Plastic parts
Two types of plastics are used in the manufacture of parts: thermoplastics and thermosetting plastics.
Thermoplastics are materials that become plastic and soft when heated. The advantage of plasticity is that you can give the desired shape. After cooling, they regain their hardness and retain their new shape.
This phenomenon is repeated as many times as the heating of the part is repeated. Thermosetting plastics are materials that harden when heated and, when heated too much, char.
Note. When repairing plastic parts, pay attention to the ISO year (type of plastic), indicated on the inside of each part.
