Can I bend PVC pipe?
PVC pipe is commonly used as electrical conduit as well as irrigation piping.

How do you mold PVC plastic at home?
To mold PVC, you would need the right temperature, pressures, and molds made of aluminum to make a “sculpture”. You simply can’t melt a PVC pipe or sheeting down to a syrup and pour into a mold and hope for the best. You can heat it and bend it sure. You can also heat it and smash it flat and even curl it.
Can you injection Mould recycled plastic?

Can you injection mold PVC?
Machine Type: Generally, PVC can be molded with reciprocating screw injection molding machines. These should consist of plasticating screws to ensure that the material in its melted form is consistent for effective injection into the mold cavity.
How thin can you injection mold plastic?
2mm to 4mmOn average, the minimum wall thickness of an injection molded part ranges from 2mm to 4mm (. 080 inch to . 160 inch). Parts with uniform walls thickness allow the mold cavity to fill more precisely since the molten plastic does not have to be forced through varying restrictions as it fills.
