Our product advantages:

Control part:

          It adopts imported computer for plastic injection machine , with large screen . high definition crystal display and human-computer interface in different languages. Through CPU independent control and individual treatment. It has raised the running speed of the control system and alarming of successive oil temperature , thus Improving the operating speed of the machine. It utilizes Closed –loop temperature control system to ensure the accuracy and reliability of the barrel temperature . The functions of cold –proof boot, alarming and parameter memory for the molding, with password protection. The injection and switch are controlled by imported ruler.

Injection part:

The excellent chrome , molybdenum and aluminum alloy screw and barrel have undergone the nitriding process, applicable to various plastic materials. The injection cylinder(258T advanced) is parallel or balance for both sides of the barrel, so as to ensure the non-deviation of the nozzle, good sealing and non-leakage. It is equipped with double guide pillar supporting system which can inject under multifarious pressure at various speeds. It also uses one-stop hydraulic pre-injection device.

Hydraulic part:

It adopts the imported top quality hydraulic components, proportional control for pressure and flow.

Molding-adjustment part:

Mold is adjusted by gear controlled by oil motor , the mold can be adjusted automatically in accordance with the setting pressure , which is both convenient and reliable.

Mold part

Five –fulcrum crankshaft structure , the mold and bracket structure together, with good rigidity and high-fitting precision, adopting the computerized optimized design. The mold employs finite element analysis, with double pulling and inserting device. Performs the functions of super sensitive low pressure protection. The mechanical hydraulic and electrical protection have the human safety. The dismountable fill-out hopper can be installed conveniently and automatically. The moveable platen adopts a fixed durable vertical brace that is adjustable. With little friction and balanced dependable moving. Clamp opening is synchro with ejection.
