Plastic Injection Molding Machine

We build all kinds of plastic injection molding machines, such as standard injection machine, synchronized injection machine, variable pump, servo motor, high speed injection molding machine, it could satisfy all kinds of customers's requests.


Introduction:

1. Reliable plastic injection machine with servo motor, equiped with servo motor, closed loop control for pressure and flow. Low noise, high precision and energy saving.

We design, manuafcture and supply our own brand of injection molding machine called "Longsheng" with clamping force ranged from 680kn to 16800kn, injection weight from 63G to 10000g, and can provide custom-built machine.

2. Inject all kinds of plastic parts, bottle preform, engineering plastic, UPVC, PVC, PE pipes fitting, pomponents for automotive, household, eletronics, telecommunication, etc

Control part:

1. It adopts imported computer for plastic injection machine, with large screen. High definiyion crystal display and human-computer interface in different languages. Through CPU independent control and individual treatment. It has raised the running speed of thr control system and alarming of successive oil temperature, thus I, proving the operating speed of the machine.

2. 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:

1. The excellent chrome, molybdenum and aluminum alloy screw and barrel have undergone the nitrilizing process, applicable to various plastic materials.

2. The injection cylinder(258T advanced) is parallel or balance for both sides of the barrel, so as to ensure the non-deviation of thr nozzle, good sealing and non-leadage. 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.

Hydralic part:

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

Mouding-adjusment 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

1. 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.

2. Perfroms thefunctions of super sensitive low pressure protection. The mechnical hydraulic and electrical protection have the human safety. The dismounable 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.
