Introduction and Machine features"

A. These kinds of machinery are designed for making PET preforms, PP/PE plastic caps for any size of water bottles. And other kinds of plastic products.

B. Features:

B1. PLC controller

With the latest control technology, this high-performance control system provides the ideal communication between the injection molding machine and the operator. The uniform operating concept and logical, clear structure of the functions make machine operation easy and user-oriented.

B2. Clamping System
With high sensitivity in the opening and closing processes and protects injection molds from excessive wear and tear. The fast mold closing device is optimized to shorten the cycle time.

B3. Automatic Mold Height Adjustment Unit
Automatic molds’ height adjustment by hydraulic motor through the gears system ensures fast and constant settings to different mold height, achieve platen parallelism and consistent tonnage. The photocell detects function to insure the high precision.

B4. Hydraulic System
The energy-saving hydraulics are fitted with sound reduced and are made of high-quality components. They allow much greater forces to be transferred and enable very uniform and precision movements of the machine.
