W-series high precision plastic injection molding machine

Detailed Product Description

 high precision injection molding mahcines: toggle type

•     Advantage of control system

1.       Advanced control system of Techmation from Taiwan.

2.       Precise and stable PID temperature control.

3.       The position of injection and ejection is controlled by linear position transducer.

4.       Multi-types of alarm information.

5.       Great volume memory, specific parameters can be stored and extended.

6.       Parameters can be recorded when changed and manufacturing under monitoring.

7.        Imported hydraulic components.

8.       Proportional control for pressure and flow.

9.       Adjustable back pressure control.

•     High-strength frame structure

Finite element analysis ensures reasonable stress distribution; continuous casting structure eliminates the stress concentration in the platen and ensures high strength and rigidity.

A. Clamping structure

1.       The continuous casting structure of back platen and the movable platen enhance the rigidity and reduce the deformation.

2.       Great between-tie-rods distance and long clamping stoke; finite element analysis of the fixed and movable platens ensures the high strength and rigidity, so the deformation is greatly reduced and high precision is ensured.

3.       High speed clamping system adopts the differential hydraulic oil circuit; low speed mold opening system ensures stable action and protects the mould from damage.

4.       Volume monitored and fix quantity lubrication system provides high lubricating pressure and ensures reliable lubrication.

    B. Injection Unit

1.       Double hydraulic injection system cylinders, short driving distance save up space.

2.       Screw and barrel are made of high quality, ion-nitride treated or by other ways of treatment alloy steel and ensures great longevity.

3.       Modular design makes it convenient and rapid to change component.

4.       Center services lubrication system in injection unit ensures convenient maintenance.

5.       Injection unit can be rotated and its easy to interchange barrel and screw.

6.       Cold start prevention of screw..

7.       4 stages control for injection and 3 stages control pressure hold make processes flexible and ensure high quality of final product.
