The ultimate guide to make the PERFECT sheet | 2024

[@plastmakers]

The best video about sheet making tips I have ever seen! Great job

[@Precious_Plastic]

Thanks tomas!

[@samueliduo-iq8hc]

@@Precious_Plastic please what is the cost of your medicines?

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.

Such an awesome community. I didn't realize it had grown so large! I want to start one of these businesses in the future!

[@Precious_Plastic]

The future will be now 😁

[@dmbrookfield]

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 :)

[@nisdedenorth6095]

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

[@rennatg]

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!

[@krobot4703]

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.

[@Carolineshavhani]

Thank you so much for this video. Is enlightening. Now I feel like trailing this.

[@ranocchiasimpatica]

Me laying on the sofa: oh yeah let's watch this video, you never know, i might need to make a plastic sheet tomorrow

[@ranocchiasimpatica]

But yeah the sheets do look pretty flawless!!! Good job!

[@dittagecoeco2738]

​@@ranocchiasimpatica ahah alla fine ti hanno convinta. Mi sa che cmq a prescindere dai lastroni di plastica, potrebbe essere la bellezza ossessiva di un lavoro artigianale ad averti intrigata. Ciiaooou

[@Precious_Plastic]

Waiting for your sheets 🔥

[@recyclingguy]

What solution are they using for 6:16 mould release? What temperature temperature does it work with?

[@jamesrowlands8971]

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.

[@raduion9492]

Hello, thank you for such nice video! Could you please tell me the type of silicone you used for preparing the mould?

[@ronyerke9250]

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?

[@polylabnz2652]

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!

[@Precious_Plastic]

And now have the knowledge! Let us know how it goes

[@geraldhoenderdos6853]

Where can we get plans for the press?

[@jasongroupindustries]

Helloo Impressive work you've done. What is the minimum and maximum thickness of plastic sheet that can be done

[@mavigogun]

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?

[@Kato414]

I had the same question in mind.

[@dmbrookfield]

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.

[@mavigogun]

@@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.

[@dmbrookfield]

@@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 :)

[@BTom16]

This would be amazing countertop material. These folks are doing brilliant work. ❤

[@lenkakraus9769]

Guys you are amazing❤

[@dittagecoeco2738]

Exciting results and style 🔥🔥🔥. I hope to get there one day 🤛

[@Precious_Plastic]

Time, failures, iterations, and a bunch of motivation will surely get you there!

[@yawwilliamssalifu4677]

this is genius precious indeed good work done

[@crowviki6583]

Great video, may i know how much the machine costs and where it is available

[@mohamedelsaka]

What type of silicone do u use?

[@chalilopez10]

Hello, the cooling press jack for how many tons is it? thank you

[@danielbraverman3349]

THank you very much. That was usefull!!

[@Precious_Plastic]

Super happy this was helpful!

[@ilantzriker7504]

Another great video with very useful information. thanks

[@victorycalibre9320]

amazing one👍👍👍👍👍👍🔥☕

[@Precious_Plastic]

Hope is useful 🤙

[@briepower8226]

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?

[@xaviercarrillo3088]

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.

[@Precious_Plastic]

Both! Depends on your business model. We've seen both models working, depends what you prefer to do

[@hailetesfay3313]

Great Video

[@bridgetkundwa9359]

hello how can i get materials/ machines for starting ths busness in our community there are many waste plastics

[@johnpyaso1846]

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.

[@mavigogun]

Pure GOLD! -or, rather, "pure PLASTIC excellence!"

[@dittagecoeco2738]

They call It precious plastic 😂

[@Precious_Plastic]

Glad you enjoy 🔥❤️🥰

[@shankariab1687]

Satisfaction when something is done perfectly 😌

[@Precious_Plastic]

Yay!!

[@TheSeaMonkeyProject]

awesome video guys! how much do you pump up every 10 mins?

[@Precious_Plastic]

Hey guys :) they pump until "can't no further", sorry not a definite number /:

[@travisjohnston1923]

Why use HIPS? It dissolves in water... Kinda why it's used for supports in 3-d printing with PLA...

[@yunusyahya1677]

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

[@kamotorosyan1106]

Not sure what the confusion is, i find prunes usually do the trick

[@frankwolf9187]

Where can you buy these sheets?

[@rakeshshah8801]

Brilliant

[@benmcintyre1538]

What type of plastic #? are “hips”?

[@Precious_Plastic]

HIPS stands for High Impact Polystyrene, so ye #6

[@Rachelcenter1]

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.

[@AuroraSinclair]

Step one: Prunes
