- In this video we are taking a quick look at a factory in Liuyang, China that makes fiberglass mortars for consumer and profession fireworks. The mortars being made in this video were all for consumer shell kits.

Awesome video Joel, love to see more China videos from you!
A pyros dream is to go to China and see their amazing firework shows.They take it really seriously there
HB were its at
I’m just glad to see you making a video . You were the very first pyro channel I came across and I miss watching your stuff !
Thanks for watching! More content on the way!
Thats cool i prefer hdpe but i cant hate on fiberglass safely gets the shells up and doesnt wiegh near as much
Totally agree with that.
I never knew they were made like this pretty cool👍🏼
I really enjoy fireworks. Hello From NM!!! Can u do another video in some small fireworks like firecrackers and such!!!! Really enjoyed your other one
I'll see what I can do.
Joel Robinson ok cool thank you!
4 rows deep ~6 feet tall = low stock. Hahaha! Awesome. Thanks for sharing.
Right!? I guess a company could order a truck load of racks and wipe that out though.
When they get enough to fill a semi is will be high stock.
Im about to make a few 5" to see how it goes
That's pretty cool, let me know how it goes!
That was amazing thank you for sharing that
Wow what a awesome video thanks man
Wow, how did I miss this video 5months ago. Very cool to see the inner makings of how this stuff gets made👍👍. I'm down for any video about the production of Fireworks both here or in China!!! Thanks for the awesome Video.
I just snuck this one past you haha!
@@JoelRobinsonPyrotechnics yes sir I'd say you did. Now Ima go back and see what else you got past me😂😂
Haha! Happy hunting!
Can't imagine working around all that fiberglass. I hate those little slivers I get just from touching the inside of a tube.
I couldn't imagine it either.
How many layers of glass do they use
That is a great question, but I did not get that information when I was there unfortunately.
Hello from Arizona 🌵 Joel!
Cheers Mate!
How many shoots resist these tubes.
Good question. You should be able to continue to use them as long as you are not seeing visual damage to the structure of the tube.
Welcome back to TH-cam Joel...
Thanks! Posted a video last week if you haven't checked it out yet :). Have another coming up soon too.
@@JoelRobinsonPyrotechnics Yup... Saw it... I'm working on posting my New Year's video and my pre New Year's video after I passed 100 subs... An accomplishment for me for sure. Still need to get a Cobra system to play with
So which is recommended more, HDPE or fiberglass mortars?
I can point out benefits of either one, but at least in the consumer world, I would recommend HDPE.
We want to make fibre glass tube of varieties size
Please tell me what kind of resin use hot or cold
Um polyester resin and fiberglass cloth
You mix cold it heats up to cure
What are they pouring??
A type of plaster mixture to create the plugs.
How does the fiberglass get picked up by the lathe to begin with?
They had some type of sleeve they would slide over the wood dowel, then start coating with the resin mixture and fiberglass strands.
@@JoelRobinsonPyrotechnics Hard to understand how that sleeve could grip the dowel and later release it.
@@goodmaro I am not sure what the sleeve was made of either but it looked like it became part of the tube. Meaning, they didn't remove it later (from what I saw)
@@JoelRobinsonPyrotechnics That much I understood. But somehow it grips the lathe well enough to transmit the spin, and then releases off the end when it's done.
@@goodmaro Now you got me extra curious haha. I'm going to see if I can get an answer from my contact that took me there.
Hey Joel, are you able to make these in an oval shape tubing as well?
Also, do you have a contact info?
Why would you want one?
I like the guy smoking while pouring the plugs.
I was actually surprised to see how many still smoked in China.
What kind of material is this plug?
Looks like hydrolic cement
Thx
I got some of thoes they seem really cheap and went with dr11s from pyroboom
They definitely are one of the cheaper routes. HDPE is the way to go in my opinion.
How many times can fiberglass mortars be reused?
As long as the plug is intact and there is no visible damage (crackles or flakes on the fiberglass, plug, etc) it should be fine to continue to use.
@@JoelRobinsonPyrotechnics Awesome, thanks! Have a happy and safe 4th!
@@andyhedden1554 you as well!
None of the ones from World Class have nails. The plugs can just slide around in the tubes without the screws holding it to the base but even then you could just pull the tube off the base. I have a video I shot recently. I have to throw a bunch out. The ones from PyroKIng use a wooden base not that plastic garbage bases.
Low Stock. lol. Those only go to the racks? None used in canister kits?
The ones on the wall were only used in racks. They also made bases to attache and use for shell kits too.
Yeah, buy bulk when you can.
gosh i can only imagine the splinters
I was thinking about the guy's back that was pouring the plugs. Or the guy cutting all the tubes breathing all the fiberglass dust.
👍👍👍
Why Fiber glass??Why are they not using Iron tubes??
Fiberglass is widely used across the world in the firework industry. HDPE is also used. Very large shells will use steel tubes and be buried in the ground, but you only see that at special events.
@@JoelRobinsonPyrotechnics - Thanks
@@JoelRobinsonPyrotechnics Bro,
Just have another doubt..... sorry in disturbing you again...., What is your opinion in using Concrete Tubes for larger fireworks displays with 6" & 8" inch diameter..
@@P4PYROIND Fiberglass is the standard for large-diameter shells. I wouldn't trust concrete to hold up with multiple shell launches personally.
@@JoelRobinsonPyrotechnics - Thanks🧡🙏
Почему наши так делать не могут
More China vids, please!
I should have a few more videos from China I'll be sharing soon. :)
Every tube I have seen has wood below the clay.
The ones specifically in this video were for those pre-built racks you can buy at some stores, but they also do tubes for shell kits.
@@JoelRobinsonPyrotechnics Which are apparently better them the garbage they put in non-bulk kits.
Is fiberglass better, Sam, worse than HDPE
It's a shame so many end up in the dump. 207
I have so many from shell kits that I either give away or make poor man racks. Save the mortars!
@@JoelRobinsonPyrotechnics Your cool man !
Right before corona hit
I mean, I was technically in the region when it first starting breaking out.
Happy you made it home before the lockdown! ☺️
