Cheers!

As a person who has worked in the Plastics industry as a setter/production technician for 7 years. This is oddly satisfying to watch. Not the normal cycle times I am use to but still great video.

[@faustinomartinez707]

Está genial. Saludos

[@erikcederb]

Have you thought about instead of just threading it on, getting plastic into the threads etc, to use a 37 degree flare hydraulic fitting on the barrel nose instead? They are super common, cheap, and would make it much faster and easier to exchange mold/plug.

[@PreciousPlasticMelbourne]

A quick release fitting is on the cards for future moulds. Stay tuned!

Great great work and explainatio. Thankyou! Please i have one thing to ask: how much torque (how manu Newtons) do you put in the torque wrench to thighten the mould's bolts? Thankyou again ciao

[@heikkiruokonen5185]

This is so cool! How does the heating work? Are those induction or thermal resistance elements? I have an unused log splitter just waiting to be misused! Do you have to use anything to keep the piston clean, like oil or silicone?

[@PreciousPlasticMelbourne]

Cheers! These are band heaters which you can pickup online. These ones are “premium” and cost $60aud each. Might be overkill.. not sure. Once the plastic is heated it doesn’t stick to the steel piston. We Use LDPE & HDPE only so we’re dealing with low melting temps.

If you don't want to invest in a CNC machine, try casting the mould from a 3d printed original part.

[@donaldmcronald6796]

Do you have any recommendations where to get metal molds at a reasonable price?

[@warwickmilne3149]

what is the biggest piece it can do. for example a fishing lure like a stick bait?

[@PreciousPlasticMelbourne]

Max would be ~50g of HDPE. A longer barrel/piston and more band heaters would be required for larger shots.

[@zulyvallejo4305]

Hi, thanks for share all these machines for create many things from waste plastic, I wonder if you can recomend how to make a plastic bottle punch machine, we work with small companies that recolect the plastic from the streets and then sell them but this process is made by hand. Thank a lot.

[@darrylhaynes9208]

Pipe thread bung

[@spencerstromberg]

What happens if you don’t pack the plastic as it’s heating? It doesn’t melt or you get air bubbles? The removing of the tip every time looks like it’ll wear out the threads over time, there’s gotta be a better solution for that, but i like it. I want to build one as I generate 20 kilos a day of scrap hdpe from my business

[@PreciousPlasticMelbourne]

Good question. We use this technique when making thick parts to prevent sink marks, however it's not necessary for all moulds. We actually found that filling the hopper and letting the rod fill the barrel after each shot actually works well for smaller parts. Having said that, it's difficult to monitor if the mould is full.

@@PreciousPlasticMelbourne what's the cost or price this machine or any contact number for purchasing.

[@excitedbox5705]

Although precious plastic is a great idea the inefficiencies of these systems are actually worse for the planet than the highly optimized industrial processes. Simply wrapping your barrel in a fiber insulation will cut your melting time and energy usage by a MASSIVE amount. Right now you are putting more heat into the room than into the plastic. This is the same as banning plastic bags. If you consider that paper bags weigh many times more and the increased fuel used for transportation paper bags use more oil than plastic bags which can be used multiple times, recycled and used to replace trash bags. Paper bags are usually destroyed half way through their first use if they even last that long. It is much more important to focus on recycling and increasing efficiency than trying to do these low tech replacements.

[@mortarriding3913]

While there's some validity to what you're saying, you skip over two fairly substantial solutions. First with PP; they set up with the intention of preventing plastic going to landfill, that there currently aren't any waste streams for. With fully developed machines, and processes, they should be able to achieve that goal, while not attempting to be competitive with more efficient industrial processes. Second with single use bags; take your own bag. Stop being lazy.

[@Acecool]

Paper comes from renewable trees instead of oil... when the bag is done being used, it can be turned into egg cartons, etc.. Obviously, cloth is better.

[@ilyarepin7750]

who cares about "the planet" people watching this want to make an injection molder for hobby or business use.

[@GoingtoHecq]

The point of precious plastic is basically that it's a sort of movement to prevent plastic from going to landfill and encourage people to reuse it. It's not meant to be some big superpac with billions of dollars in research funds providing industrial machinery and fully researched and finished processes. It's more a social thing to help bring about a necessary change in how we view and use plastic.
