Categorization as either a thermoplastic or a thermoset has to do with the way the plastic, once created, responds to heat. Thermoplastics: Plastics that can be heated to their melting point, cooled, and re-heated again without significant degradation. Instead of burning, thermoplastics liquefy, allowing them to be easily injection molded and then subsequently recycled.
This method is just one step, from PET granule to finished bottles, all the processors are done in one integrated machine. That is from the injection mold of the preform to the removal of the preform from the injection cavity, and to stretch blow the preform to a bottle all in one machine, while the temperature remain constantly high for the whole process as injection molding and blow molding .

Plastic Injection Molding Process. Injection molding is one of the main methods by which parts are manufactured from plastic. The first step in the injection molding process is to feed plastic pellets into the hopper, which then feeds the pellets into the barrel. The barrel is heated and contains a reciprocating screw or a ram injector.
Once the plastic resin is melted completely into a liquid, the next step is to drain it of imperfections and contaminants. The way this is done is the molten thermoplastic travels down the screw and through a series of screens to be filtered.
Plastic products are made out of raw plastic using a host of moulding techniques  which always involve mixing and melting of the raw material inside a screw extruder , as the first step. One exception to this are epoxy resins , which are diluted in a solvent, cast to the final shape in a liquid form and solidified as their two ingredients react and co-polymerise .
Plastics are polymers, chains of simple organic chemicals (monomers), linked together in long chains. The monomers are synthesized in refineries, from oil. The linking of the monomers in the polymer chain is done inside polymerization reactors, un.
