Frequently Asked Questions

What materials can this injection molding machine process?

This machine is specifically designed for PET (Polyethylene Terephthalate) material, primarily for producing bottle preforms for beverages and food packaging.

How precise is the injection control system?

The machine utilizes a high-precision linear potentiometer with a deviation of less than 0.01mm, combined with a PID temperature controller accurate to within ±1°C.

Is the machine easy to operate for different bottle sizes?

Yes, the microprocessor controller features a shut-down memory that can store up to 100 sets of mold data, allowing for quick transitions between different production requirements.

What safety features are included for the screw and heating system?

The PID temperature control system includes limitations for screw cold starts and broken wire detection to prevent mechanical damage and ensure consistent heating.

Does the system include auxiliary equipment?

The full setup includes a dehumidifying dryer, auto-loader, chiller system, and mold temperature controllers to provide a complete production environment.

What is the construction material of the machine?

Key components and contact parts are made from high-quality Stainless Steel (SUS304 and SUS316) to ensure durability and food-grade safety standards.
