Injection molding machine build

Hi everyone, I recently came up on a few TONS of thermoplastic rubber and polymer pellets. I am attempting to build an injection molding machine using various scraps from the massive collection of junk i have available. To start, i have multiple choices for the heating elements including electric kettles, curling irons, and basic clothes irons. I plan to utilize steel pipes and flat steel plates along with a hydrolic jack and air compressor tips for this project. If anyone has some ideas, advice, or basic blueprints for this type of machine build, i would be ever so grateful. Thanks in advance, i look forward to hearing your inputs! Shelley aka TwistedTools

Have a look on AliExpress. You can get a cheap injection molding machine for like $1000. I would recommend just buying that, but if not have a look at what they've got and try to duplicate it.

Just a thought to work FROM.

I worked in reproduction of WAX PARTS, for lost wax casting.

Our SHOP MADE wax melting pot was a smaller sized PRESSURE COOKER, that was PRESSURIZED with a *dry output compressor line* with a regulated pressure per each wax needs (multiple pots, we NEVER cross contaminated WAXES).

The output was a simple bronze port, with a simple 90° valve. We had multiple MOLDS, for each kind of WAX USED (a lower temperature wax & a high temperature WATER SOLUBLE WAX were our two main items). The Water soluble wax was a CORE, which AFTER it was inspected, and possibly corrected, had the lower temperature wax injected AROUND IT.

That made our FINISHED part, NEARLY impossible to machine from metal (Aluminum in our case). I can not provide aphoto's, the product was a PATENTED PROPERTY, but the designing process is used by many COMPANIES.

MAKE 50 of those and put them into a 5 gallon bucket of water, the SOLUBLE part of that wax, disintrigated (that was just corn starch, mixed with high temp. Wax at the factory) . . .

My point, you might come up with a lower cost build it yourself injection for YOUR MATERIALS.
