Great minds think alike. I had considered using a similar drill press frame as the basis for our next model, but we want greater capacity, so we're going with a powered screw drive. The video may release before year's end.
Th model 4a includes a capacity-stretching tweak (=20%) but it will always be limited by the throw on the drill press. Still, it's adequate for many users. Video on the 4a to follow shortly. I look forward to seeing your powered system. I've been harbouring similar ideas for a long time.
No extruding all pressure. Ball screw driven extruders are the newest goto with geared down motor drive for adding incredible amounts of torque. Clamping is then the issue. 😊
Permission to ask, I tried vertical injection molding with a manual lever using HDPE plastic, but when in the barrel the HDPE plastic melts unevenly, the bottom near the nozzel has melted while the top is still thickened, how do I make it liquid evenly for HDPE material?
Even when this model or the new model is available to customers, be prepared to pay the £113 costs which is 156.00 US dollars just for the shipping to the USA
Tymzr, when the new one is ready I'll post a video here, so please subscribe to see that. Right now, life is complicated so I don't know when I'll be able to give time to this.
I've got onr of those "drill press" stands.... they're not what I'd call "great" but they sort-of "do" for home use. I've been on the look-out for a reasonably priced injection moulding machine for ages.... this might be a good plan.
Hello again. Yes, they are cheap and not very rigid. The reason this model worked is that the frame doesn't have to be rigid. The piston alignment and the strength relies on the downward force from the lever being transmitted through the mould. The second reason I stopped making these is that people just wouldn't get this, despite clear instructions sent to them. Mine is still perfectly aligned after several years of use, but some customers got fded up that theirs went out of alignment and froze. I'd get them back to re-align them which is annoying. The new model will solve both problems. The cylinder doesn't need any boring, and the piston cannot move out of alignment. I won't say how those are accomplished but you might subscribe if you'd like to see a video when it's available.
The element is about 120 watts. From cold, it takes about 5 minutes to heat the machine to working temperature. After that, from one shot to the next, you have to wait a couple of minutes to melt the new load of plastic. You can speed things up by lagging the injector barrel.
Firstly, I am not master in this field. However, what I see is the heater band wire directly connect to port 1 and 2 (~220V) of the PID controller. My concern is whether we get electrick shock when touching to the heater band during the operation (I mean when the heater bands getting hotter to reach the set temperature value) ???
Assuming i'm making something that requires a larger volume of plastic than i can pour in one shot, will this create weak points in the final mould due to earlier pours being cooler than later ones?
what would be the melting temperature of the molten plastic? & are you using recycled plastic such as -HTPP used for 3d printers. will you be devising a machine that makes larger castings of objects. when I worked in a plastics factory we used polyprophelane beads in sacks for the plastic material
Nigel, the melting point of the molten plastic depends on the plastic you use, but 200 - 250C is usual. Yes, I use HDPE and PLA - and that PLA IS from failed 3D prints. I already have a larger machine but it is not for resale currently.
Hello Chris, I would like to know if is possible buy only the stainless steel funnel with the plunger in order to avoid the excesive P&P rates to my country (Argentina). Please let me know if is possible and the price. Kind regards, Luis
Hello Luis, yes it is possible. I could provide the controller unit too - or not. When posting parcels from the UK, the prices are coarsely banded. 2Kg is a huge break point. Up to 2Kg a parcel to Argentina costs about £25. Anything at all over that costs about £70.

Hey man awesome build... I am looking to do injection molding for prototyping with PA plastic. Have you tried that already? Edit: Ah nvm I noticed that my pieces are too big with ~40000mm³... Could you build such an injector?
Depends on the mould Rodney. If the ways are wide and the part simple, mould heating is not necessary. As things get narrower, longer and more complex, injection gets harder and heating helps to keep plastic flowing until the mould is filled.
Rene - this machine will extrude any thermoplastic which melts below about 240C. Beyond that I cannot tell you as I have no experience with Teflon, but in any case, this machine is not currently availabel for customers.

Pretty clever. Liked the idea of using a resin to make the mold with. The Nazis did something like that with the gears for their planes? I think that it was. They mixed their phenolic resin with silica sand with a lost wax method. If memory is serving well enough, I think that the article that I read claimed that they might have gotten 80 or so gears from a resin/sand mold. All that they did after that was trim the new gear to speck with a file.
Hi Chris, this is great! We have a plastic shredder that we built from the plans of precious plastic and we are looking for a tool for transforming the chips into something useful. I just looked at some plans to build a similar tool like yours and then I found your machine with the drill press. I like the idea and i actually just saw that exact model in a Discovery Center here. Do you provide the plans for your machine? Or you only sell the machine? I am currently in Panama, so shipping is expensive / takes a long time, so I was wondering if I could get those ss parts machined here... Thanks so much, Nike
Hello Nike, and thanks for your comments. I do not provide plans, sorry. Postage to Panama is about £130. Do you mean you saw THIS model in a Discovery Centre? If so, please let me know where it is and if there is a website for it. Thanks Chris
Chris Wesley thx for the replay. Yeah I am pretty sure it was THIs exact drill press model. I was just looking for one the other day for a project I was working on, that’s why I remember it. www.discoverycenterpa.com/ I might order one of your machines and pick it up in Germany when I am home for xmas. How long does it take to ship to Germany? And how much is the shipping? Thx!
Oh sorry Nike, I misunderstood you. I thought you meant this exact PLASTIC INJECTION MOULDING MACHINE! That would have been concerning as I haven't sold one so far in Panama. Sorry to have wasted your time. Thanks again though - Chris
*i have many questions* Is there a reason why stainless steel is used - can it be aluminium or copper? To have more capacity, can the piston and barrel be made a larger diameter, rather than length? When injecting plastics of different color or plastic type, how is the funnel and barrel cleaned to avoid mixing of colors or plastic types? You mentioned in one of your videos that the mould could be made of plastic resin. Would the heat from the molten plastic deform a mould made of plastic? How much torque do you estimate that you are applying to the lever arm when filling the mould? :
Critical look - here are your answers. Both aluminium and copper oxidise - they tarnish. The oxide is then available to contaminate the melted plastic and the part you'remaking. I know that LNS technologies nickel plate their hot parts, but my concern there is that - when the plating's gone, the machine is open to oxidation (rust in that case). You can make the piston wider, but then the injection pressure for a given lever force is lower. It's a compromise point which you choose for the work you have in mind for the machine. The barrel is cleaned ("purged" as the industry calls it) by flushing it with something. You can buy purging compounds but I just push the new plastic in after the old and accept that I'll have to do it a few times before the old plastic is fully gone. No, the resin moulds don't melt. The injection force needed depends on the plastic being used, the temperature of the melt, and the mould, and the specific design of the mould. Long thin runs present a lot of resistance whereas short fat runs present a lot less. My GUESS is that the down force for a typical mould would be in the region of 30Kg at the lever handle.
Mehrdad - the short answer is no - not yet. The current model is 1.2 cubic inches, whic is about 20 cubic centimeters. Plastic density is about 1g per cubic centimeter, so that's also about 20 grams.
Hi, This is something we are looking into right now to reduce lead times of proving new mould tools. You mention in the comments that there is a sales page?
Hi SImon, there is a link to the new model video in the video description. I have also updated the description to link to the sales page for it, but pelase read the notes before contacting me. Many thanks, Chris
Hi I have a new design that I would like to be able to injection mould at home, it has 7 parts and the volume of plastic would be around 950g. each part is no more than 200g do you or could you make something?
Hi Adam. The capacity limit on the 4a model - the successor to this machine (th-cam.com/video/tn6-MgJ6oVU/w-d-xo.html) - is 1.2 cubic inches. For a typical thermoplastic like HDPE this equates to a mass of 19 grams - so this machine is far too small for your needs. You need a machine with ten times this capacity. Making something would be possible but it would be a prototype and involve you in a lot of up-front investment.
after reading your comment I have decided to remodel a juicer into an injection molding machine, Im seeing alot of people designing benchtop injection molding machines but all have a low capicity 10-20g. I see no reason why bigger capcity is a problem with these set ups. you are really only limited to barrel size and shaft. I take it putting a number of shots into the same mold isn't feasible ? I guess you would get separation, could this be overcome by heating the mold?
Adam, multiple shots into one mould is not feasible, no. I've also seen a lot of other people making injection moulding machines. And whilst they man demonstrate the concept OK, they are not usually practical machines. Aluminium, for example, oxidises in air, and will deposit a powder into the body of your parts. There are problem with scaling up a small machine to make a big one. One is that plastic is a very poor conductor of heat and as you increase the barrel width you increase the time it takes to melt the load throughout its width. Commercial units get around this problem in a variety of ways. Another problem with increasing barrel diameter is that the injection pressure for any given handle force drops. (pressure is force divided by area). Of course all obstacles can be overcome - commercial machines, after all, DO exist. But it's not as easy as you may think. Have fun & good luck.
Hello Joshua, it is on EBay for £425 + £25 P&P. www.ebay.co.uk/itm/201749893363. If you'd rather buy it privately, we can split the EBay fee I wouldn't have paid - so £425 all-in. The nearest thing sold commercially to this is LNS technologies' machine - currently on sale for $1,800. (techkits.com/products/model-150a/) Frankly - there's is a more professionally finished machine, but then they're a professional company. Mine does what theirs does, and it's solid stainless (there's was nickel plated last time I asked), and it's a third of the price.
Hi Stephane. I'm confused; the video you commented on is about a plastic injection mould machine I built myself. The mould is homemade from aluminium stock and those green pellets are not glue. Perhaps it's a language issue? Do let me know if I can help.
Estoy en el Reino Unido pero actualmente no los estoy haciendo para clientes. Pero si quieres, suscríbete al canal. Haré un anuncio en video cuando el nuevo modelo esté disponible.
I sell these. You are asking me to invest a lot of effort 0 in exchange for nothing - to give you proprietary information enabling you to build & sell them for yourself. Gee, that's a tough one but I'm going to decline.
Please read the comments and/or sales page for details. I'm not making this model but if you'd like to knwo when the new model is available, Subscribe and you'll get notice of the introductory video.
It depends on who is making it, whether it's aluminium or steel, and what the part is. If you outsource it, then unlikely less than several thousand pounds for an aluminium mould and far more for stainless steel. I make my own from aluminium or brass with the aid of my metal lathe. If you have a CNC router, you can make your own even easier. It's now possible to 3D print moulds, though I have no experience of that so far.
Pretty please? Suppliers and supplies come and go. Just pile on to EBay and search for one, but be careful to order one with a cast iron base. There is another kind which look the same but are far inferior - they do not have the cast iron base.
Hi leopoldo please write for pricing via my sales page as this changes from time to time and remains confidential, though there is a dated estimate in the video.
Hi Foxy, yes I do, but much of the cost and the work is in these stainless steel parts. You'd need three parts: 1. The barrel itself, with drilled tapped holes for the bottom support strut and thermocouple 2. The funnel ring, drilled and tapped for the top support strut 3. The piston, machined for a close fit in the barrel. Please write to me at chris@chriswesley.org for a price. Best Wishes, Chris

Is it possible to make one that makes nursery pots, say the large ones? For example, 20 inches tall and 20 inches wide?
No, this simple heating scheme maxes out not far from this capacity. Larger capacites need more complex design and are correspondingly expensive.
When you drive the plunger down, doesnt the piston trap some air in with the plastic potentially forming bubbles?
Hi Joe. No. Molten plastic is quite viscous and the piston doesn't need to be a gas-tight fit so air can escape past it.

All that they did after that was trim the new gear to speck with a file.
good！！！！
Hi Chris, this is great! We have a plastic shredder that we built from the plans of precious plastic and we are looking for a tool for transforming the chips into something useful. I just looked at some plans to build a similar tool like yours and then I found your machine with the drill press. I like the idea and i actually just saw that exact model in a Discovery Center here.
Do you provide the plans for your machine? Or you only sell the machine? I am currently in Panama, so shipping is expensive / takes a long time, so I was wondering if I could get those ss parts machined here...
Thanks so much,
Nike
Hello Nike, and thanks for your comments. I do not provide plans, sorry. Postage to Panama is about £130. Do you mean you saw THIS model in a Discovery Centre? If so, please let me know where it is and if there is a website for it.
Thanks
Chris
Chris Wesley thx for the replay. Yeah I am pretty sure it was THIs exact drill press model. I was just looking for one the other day for a project I was working on, that’s why I remember it. www.discoverycenterpa.com/
I might order one of your machines and pick it up in Germany when I am home for xmas. How long does it take to ship to Germany? And how much is the shipping?
Thx!
Oh sorry Nike, I misunderstood you. I thought you meant this exact PLASTIC INJECTION MOULDING MACHINE! That would have been concerning as I haven't sold one so far in Panama. Sorry to have wasted your time. Thanks again though - Chris
Chris Wesley yeah no ☺️. Then I would have bought it right there 🤣
*i have many questions*
Is there a reason why stainless steel is used - can it be aluminium or copper?
To have more capacity, can the piston and barrel be made a larger diameter, rather than length?
When injecting plastics of different color or plastic type, how is the funnel and barrel cleaned to avoid mixing of colors or plastic types?
You mentioned in one of your videos that the mould could be made of plastic resin. Would the heat from the molten plastic deform a mould made of plastic?
How much torque do you estimate that you are applying to the lever arm when filling the mould?
:
Critical look - here are your answers.
Both aluminium and copper oxidise - they tarnish. The oxide is then available to contaminate the melted plastic and the part you'remaking. I know that LNS technologies nickel plate their hot parts, but my concern there is that - when the plating's gone, the machine is open to oxidation (rust in that case).
You can make the piston wider, but then the injection pressure for a given lever force is lower. It's a compromise point which you choose for the work you have in mind for the machine.
The barrel is cleaned ("purged" as the industry calls it) by flushing it with something. You can buy purging compounds but I just push the new plastic in after the old and accept that I'll have to do it a few times before the old plastic is fully gone.
No, the resin moulds don't melt.
The injection force needed depends on the plastic being used, the temperature of the melt, and the mould, and the specific design of the mould. Long thin runs present a lot of resistance whereas short fat runs present a lot less. My GUESS is that the down force for a typical mould would be in the region of 30Kg at the lever handle.
Price
Hi Chris, I have a 2 cavity mould, the total weight of the two products is 30 grams.
Do you have a machine suitable for that.
Mehrdad - the short answer is no - not yet. The current model is 1.2 cubic inches, whic is about 20 cubic centimeters. Plastic density is about 1g per cubic centimeter, so that's also about 20 grams.
Thanks for your reply.
Hello again Chris, would you be interested in building a 2 cubic inch machine for me?
Yes. I will reply to the email you sent me with details.
I have also sent you an email with more information With pictures of the mould and the end product. Looking forward to hearing from you.
Hi, This is something we are looking into right now to reduce lead times of proving new mould tools. You mention in the comments that there is a sales page?
Hi SImon, there is a link to the new model video in the video description. I have also updated the description to link to the sales page for it, but pelase read the notes before contacting me. Many thanks, Chris
Hi I have a new design that I would like to be able to injection mould at home, it has 7 parts and the volume of plastic would be around 950g. each part is no more than 200g do you or could you make something?
Hi Adam. The capacity limit on the 4a model - the successor to this machine (th-cam.com/video/tn6-MgJ6oVU/w-d-xo.html) - is 1.2 cubic inches. For a typical thermoplastic like HDPE this equates to a mass of 19 grams - so this machine is far too small for your needs. You need a machine with ten times this capacity. Making something would be possible but it would be a prototype and involve you in a lot of up-front investment.
after reading your comment I have decided to remodel a juicer into an injection molding machine, Im seeing alot of people designing benchtop injection molding machines but all have a low capicity 10-20g. I see no reason why bigger capcity is a problem with these set ups. you are really only limited to barrel size and shaft. I take it putting a number of shots into the same mold isn't feasible ? I guess you would get separation, could this be overcome by heating the mold?
Adam, multiple shots into one mould is not feasible, no. I've also seen a lot of other people making injection moulding machines. And whilst they man demonstrate the concept OK, they are not usually practical machines. Aluminium, for example, oxidises in air, and will deposit a powder into the body of your parts. There are problem with scaling up a small machine to make a big one. One is that plastic is a very poor conductor of heat and as you increase the barrel width you increase the time it takes to melt the load throughout its width. Commercial units get around this problem in a variety of ways. Another problem with increasing barrel diameter is that the injection pressure for any given handle force drops. (pressure is force divided by area).
Of course all obstacles can be overcome - commercial machines, after all, DO exist. But it's not as easy as you may think.
Have fun & good luck.
How much are you asking for it with postage within the UK? Thanks
Hello Joshua, it is on EBay for £425 + £25 P&P. www.ebay.co.uk/itm/201749893363.
If you'd rather buy it privately, we can split the EBay fee I wouldn't have paid - so £425 all-in.
The nearest thing sold commercially to this is LNS technologies' machine - currently on sale for $1,800. (techkits.com/products/model-150a/)
Frankly - there's is a more professionally finished machine, but then they're a professional company.
Mine does what theirs does, and it's solid stainless (there's was nickel plated last time I asked), and it's a third of the price.
Hello
i have found your youtube video for terrific glue injection
can you give me the address to buy the mold and glue
thank you in advance
Hi Stephane. I'm confused; the video you commented on is about a plastic injection mould machine I built myself. The mould is homemade from aluminium stock and those green pellets are not glue. Perhaps it's a language issue? Do let me know if I can help.
Please explain how plastic molds can be used instead of an aluminum mold.
Henry, it's not sometnhing I've loooked a lot in to but there is material on the Internet for you to research.
if you don't mind can you tell me what type of plastic did you use?
Alvin, I can't recall, sorry.
I need to buy one such machines. But I need to take 350x350x6 capacity of palstic mold. How much will it cost?
I can't build such a machine for you. Machines like this adopt a simple heating strategy which cannot be scaled to the size you're interested in.
What type of Chips used for it? HDPE?
Whatever you like, more or less. The machine will heat to around 300C. I use HDPE.
mucho le agradezco la información y si me podría indicar de que lugar es saludos.
Estoy en el Reino Unido pero actualmente no los estoy haciendo para clientes. Pero si quieres, suscríbete al canal. Haré un anuncio en video cuando el nuevo modelo esté disponible.
How to buy it. Perfect and capacity for a project for me. 💕
Whats the biggest size of mould it can take?
1.2 cubic inches
Asi machine india me milti ha kya
Hi how much is 1 of these? thanks
i want to made it at home . so please send me all details , drawings and sizes of its part ...... please help me ,,,,,, please , please , please .
I sell these. You are asking me to invest a lot of effort 0 in exchange for nothing - to give you proprietary information enabling you to build & sell them for yourself. Gee, that's a tough one but I'm going to decline.
Are you making more of these? I think I'd like one:))
Please read the comments and/or sales page for details. I'm not making this model but if you'd like to knwo when the new model is available, Subscribe and you'll get notice of the introductory video.
@@chriswesley594 is this still available
Whats the cost of having a aluminum mold made ?
It depends on who is making it, whether it's aluminium or steel, and what the part is. If you outsource it, then unlikely less than several thousand pounds for an aluminium mould and far more for stainless steel. I make my own from aluminium or brass with the aid of my metal lathe. If you have a CNC router, you can make your own even easier. It's now possible to 3D print moulds, though I have no experience of that so far.
Any idea when will your new model be available for sale? I'm interested in buying one.
Sorry, I can't make any commitments now, but hoipefully in a month or two.
hi, i realise this is an old video but is this still available
Please read the FAQ. SHort story - "No, but SUBSCRIBE to be notified when I release the nex model".
Hi chris
Will you post it to Australia.
Total cost for machine and postage please.
This model is no longer made, as mentioned in very many comments here before!

Hello Chis Wesley!! I am S.korean and I was very impressed your plastic injection machine! Can i use your injection image for korea plastic campaign??
Pleas read video description.
Hi Chris, what kind of metal is the mixer made of?
Hello Omar. If you mean the injector barrel, then it tells you in the video. It is solid stainless steel.
Really cool! FYI, the link to your coaching site off your injector page has a typo so it goes to a 404.(forgot the "e" in "life") :)
Thank you Rush. I've fixed it.
Where do you get the plastic pellets from?
Matthew, it's 2021. What would be your guess as a first place to start?
Can I have the link to the drill press? I might make something like this.
Pretty please? Suppliers and supplies come and go. Just pile on to EBay and search for one, but be careful to order one with a cast iron base. There is another kind which look the same but are far inferior - they do not have the cast iron base.
Thanks. I had to search a little because most of them are aluminum, but they are still really cheap.

Wondering if you sell these or plans to make them?
Yes, I sell them. Please read the description for the link.
I am waiting for your response. Thanks.
Sorry I am not currently accepting new build backlog orders.
Hello Chris, what is the price of the machine? I am in Mexico
Hi leopoldo please write for pricing via my sales page as this changes from time to time and remains confidential, though there is a dated estimate in the video.
HI
Do you sell the cylinder and plunger separate?
Hi Foxy, yes I do, but much of the cost and the work is in these stainless steel parts. You'd need three parts:
1. The barrel itself, with drilled tapped holes for the bottom support strut and thermocouple
2. The funnel ring, drilled and tapped for the top support strut
3. The piston, machined for a close fit in the barrel.
Please write to me at chris@chriswesley.org for a price.
Best Wishes,
Chris

You need to get into 3d printing
You obviously haven't seen my 3D printing videos, Crispy. 3D printing rocks. I've earned my living from mine for hte last 3 years, but it has limitations. You can inject a part in seconds and it iwll be far stronger and with a perfetc mirror finish. You can't do that with a 3D printer.
Anyone else finding the link to the model dosent work?
Boyce, sorry but your question makes no sense. Link to model doesn't work?
