Injection Molding Machines for PET
-Electric Plasticizing
1. Introduction
PET is a widely used thermoplastic in the packaging industry, especially for products like preforms, bottle caps, and containers. However, due to its high melting point, moisture sensitivity, and fast crystallization behavior, PET cannot be processed using standard injection molding machines.
Our PET-specialized machines are purpose-built to handle these challenges, ensuring high-quality, crystal-clear output and efficient cycle times.

6. FAQ Section
Q1: How is a PET injection molding machine different from a standard one?
A: PET machines use a specialized screw, have higher plasticizing capacity, and require integrated drying and heating systems.
Q2: What screw L/D ratio is best for PET?
A: Typically 24:1 to 26:1, depending on the shot size and product thickness.
Q3: Do I need a special drying system for PET?
A: Yes. PET requires drying at ~160°C for 4–6 hours to remove moisture before molding.
