Totally different plastics require completely different melting temperatures and strategies. For instance, polyethylene (PE) may be melted at decrease temperatures utilizing a easy plastic extruder, whereas PET and PVC require extra specialised gear.
2. Finish Product
The specified finish product can even decide the kind of gear wanted. If you wish to produce pellets or flakes, you have to a granulator. If you wish to create a selected form or object, you could want a mould or injection molding machine.
| Plastic Kind | Melting Temperature | Gear |
|---|---|---|
| Polyethylene (PE) | 105-135°C | Plastic Extruder |
| Polyethylene Terephthalate (PET) | 250-270°C | PET Recycling Machine |
| Polyvinyl Chloride (PVC) | 150-170°C | PVC Extruder |
3. Scale of Operation
The dimensions of your operation can even affect your gear alternative. If you’re recycling small quantities of plastic, a handbook plastic shredder could also be enough. For bigger operations, a completely automated recycling line could also be crucial.
Melting the Plastic
Melting plastic is a course of that can be utilized to recycle plastic or to create new objects. The method includes heating the plastic till it liquefies, after which pouring or molding it into the specified form. There are a couple of completely different strategies that can be utilized to soften plastic, however the most typical methodology is to make use of a warmth gun. Warmth weapons are designed to emit scorching air, which can be utilized to soften plastic. To soften plastic utilizing a warmth gun, first clear the plastic and take away any grime or particles. Then, maintain the warmth gun about 6 inches away from the plastic and transfer it forwards and backwards till the plastic begins to soften. As soon as the plastic is melted, you may pour it right into a mould or form it by hand. Watch out to not overheat the plastic, as this will trigger it to burn or smoke.
As soon as the plastic has been melted, it may be used to create quite a lot of completely different objects.
