Please share more details on the surfaces of the hot press. What is the thickness? Are you using the same heating elements from the original design?Any details to look for. It would really help people like me who is in the process of building their sheet press set-up
Oh yeah please share some more about the machine, I’m also in the process of building a sheet press and I’m very interested about those thicker aluminium plates and how did you do with the resistances? Thanks!
I presume the mold is OVER FILLED, so that applied pressure encourages voids to escape out the sides as the squeeze is applied. Here's what I don't get: once both faces are in contact with the mold frame, no more pressure can be applied... yet, part of their formula for bubble-free sheets involves interval cranking of the hydraulic press.... which would be impossible if the frame mold were in contact with the upper press face. Is the top face of the press never in contact with the frame mold? Is pressure in the mold entirely relying on the viscosity of the the plastic at melt temperature?
I'm also interested in this, but bubbles implies air, in concrete you would use a concrete vibrator to agitate the bubbles, but you can't agitate, but as air escapes and the volume changes you would need to increase pressure again? I guess at an industrial scale or more complex press (expesnive), that press would be automatic and would maintain a constant pressure. Both the videos were brilliant on this topic.
@@dmbrookfield While eliminating some color patterning control, the common method to eliminate voids is to fill the press mold from an extruder not unmelted shred stock. A plunger-type top mold would allow for greater sustained pressure application; looking back at the development of the Precious Plastic Sheet Press, early versions featured plunger-type mold tops. Flat mold tops reduce needed clearance, fabrication costs, ease removal and maintenance demands, reducing production time and labor costs. All design is a trade.
@@mavigogun Thank you so much for the answer, I keep forgetting to check for replies. Yup everything is a trade off, increasing the pressure with a motorised more powerful press would do more as well I guess, but that increases costs.. Thanks :)
I can think of a few things to optimize production, but with their relatively 'low tech' approach working so well, it'd be difficult to throw anything on other than to boost production rates. Getting rid of bubbles is really quite easy, which is to dry your material, usually for several hours at half of what your molding temperature is running. Now if you want to crank out as many as you possibly could in one day, having water-cooled platens would make a Huge difference. That would be the single largest difference and relatively easy to do, especially if you have access to CNC partners. Pumps don't need ridiculous flow rates (making the operation cheaper) and the water source itself can be recycled over and over without much degradation in a closed loop, as the water is never coming into direct contact with your plastic.
Hi, im interested in doing this. What price do these sell for, please? Also, examples of a few types of customers who are buying them. Because I'm concerned that they go to the bigger companies. No?
Bro, love followed your program.lam interested can you come to Papua New Guinea 🇵🇬 in port Moresby and teach me so that we learn from your knowledge.Thankyou, John Pyaso.
I probably missed it, in the last video but what do you do with the final product (the sheets)? just sell it to businesses or do you create thing with them? thank you.
What are some of the primary uses of these large sheets? Are they mainly fashion or design pieces? Can they be used in a source of manufacturing? Im genuinely curious as to what happenes after the sheet is made.
I once worked in a shop that made molds for blowmolding. Those molds had passages and fittings for liquid heating and cooling. Do you have any plans to try that out?
Such an awesome community. I didn't realize it had grown so large! I want to start one of these businesses in the future!
The future will be now 😁
Me laying on the sofa: oh yeah let's watch this video, you never know, i might need to make a plastic sheet tomorrow
But yeah the sheets do look pretty flawless!!! Good job!

Waiting for your sheets 🔥

I have to say I loved watching both the videos from TRS great detail on the problems, sort of makes you want to go visit them :)
Thank you so much for this video. Is enlightening. Now I feel like trailing this.
What solution are they using for 6:16 mould release? What temperature temperature does it work with?
Where can we get plans for the press?
Guys you are amazing❤

Awesome! Thank you guys. I'ts gonna take me a while to get to such great quality sheets, haha. But I'm not giving up!
And now have the knowledge! Let us know how it goes
this is genius precious indeed good work done
I'd love to hear some in detail safety information about handling HIPS as we've so far avoided it due to a lack of clarity on that.

This would be amazing countertop material. These folks are doing brilliant work. ❤
What type of silicone do u use?
Helloo
Impressive work you've done.
What is the minimum and maximum thickness of plastic sheet that can be done
amazing one👍👍👍👍👍👍🔥☕
Hope is useful 🤙
Hello, the cooling press jack for how many tons is it? thank you
Great video, may i know how much the machine costs and where it is available
Why use HIPS? It dissolves in water... Kinda why it's used for supports in 3-d printing with PLA...
hello how can i get materials/ machines for starting ths busness in our community there are many waste plastics

Both! Depends on your business model. We've seen both models working, depends what you prefer to do
can you come up with a way for the average person to make sheets themselves. The average person doesnt have the equipment that you do.
awesome video guys! how much do you pump up every 10 mins?
Hey guys :) they pump until "can't no further", sorry not a definite number /:
Brilliant
What type of plastic #? are “hips”?
HIPS stands for High Impact Polystyrene, so ye #6
Where can you buy these sheets?
www.therecyclestudio.com/
Step one: Prunes
The best video about sheet making tips I have ever seen! Great job
Thanks tomas!
@@Precious_Plastic please what is the cost of your medicines?
Hi I want to start recycling plastic from my place Kenya. I'm looking for a machine that can work well please help. Thank you
Not sure what the confusion is, i find prunes usually do the trick
Pure GOLD! -or, rather, "pure PLASTIC excellence!"
They call It precious plastic 😂
Glad you enjoy 🔥❤️🥰

Hello, thank you for such nice video! Could you please tell me the type of silicone you used for preparing the mould?
Another great video with very useful information. thanks
Great Video
Satisfaction when something is done perfectly 😌
Yay!!
THank you very much. That was usefull!!
Super happy this was helpful!
Exciting results and style 🔥🔥🔥. I hope to get there one day 🤛
Time, failures, iterations, and a bunch of motivation will surely get you there!
