Freely 100 points setting parison container wall-thickness control.

Precision of the analog reach upto 16 bytes.

Display fully-automatic cycle time.

Display real-time failure alarm information and diagnosis.

Alarms display for adjustments of heating, temperature-value, pre-heat, high-low temperature...

Multi-function safety interlocks.

Freely Parameters setting on panel buttons directly.

Mould Die Head System

The minimized centre distance of multi-runner die-head design provide higher flexibility of the mold with more cavities.

Adopt centre feeding flow-distribution and core-type complementary runner give container wall-thickness more even&faster color change.

Extrusion system

Frequency converter for motor driver.

Enhance screw-end cooling zone water-jacket design provides efficient material feeding, higher extrusion capacity and stable quality control.

High precision temperature PLC control.

Multi-purposes design of screw provides not only uniform plasticization but also high production.


Hydraulic System

We co-operate with the world-brand high standard hydraulic manufacturers, Vickers, Bosch\Rexroth, Yuken and Moog providing us the most efficient pumps, proportional valves, directional valves, accumulators and filters in addition to our professional circuits-design, fast response, high speed, stable, energy saving, low noise, long working life and both environmental&user-friendly from our machines are gained.

Air Supply System

Thanks to our experience for many years in this field and the expertise suppliers of FESTO and SMC from Germany and Japan, we adopt and produce a series of high quality&reliable air-circulation system including the blowing technology, clearance airing and airing drying system to our machines.


Clamping system

Clamping cylinder at mold platen centre giving evenly-pressure loading and good quality production hence longer mold life is also benefited.
