What form is the plastic after melting?
I would like to know how does it look like/feel like after melting the mixed plastic? Do we need special care for these “materials”? Besides, I wonder if any poison gases/smell will be released during melting and compression? If yes, is there any good way to control or even clear the gases?
Melting plastic makes the plastic particles transition from Solid to hot liquid, and then back to solid after cooling down.
While liquid, the plastic is really hot (usually around 100 and 250 celcius degrees, and touching it will leave an uncomfortable burn because it will stick to your skin).
Some types of plastic don’t really release any gases like PLA or PETG, but some others like PVC release fumes that are irritant to your lungs. You can find more info about it here:
Most types of plastic fumes are not deadly, but if you are planning to work on any of the machines like the extruder, compression or injection machine, I recommend you to work on an open space to allow any fumes to dissipate quickly. If you are working on a place with low ventilation, it would be good to buy an air purifier and step away of the room while the melting is in progress.
