Liquid Silicone Rubber Keyboard Moulding Machine Precision Keypad Equipment
Product Description
Liquid Vertical Injection Molding Machine With Double Sliding Board.
BETTER LSR Injection Molding Machine made with CE and ISO Production Controller, Vertical Double Slides Table LSR Injection Molding Machine is widely used in medical silicone products, electron silicone seal,ect.
Vertical Liquid Silicone Rubber (LSR) Injection Molding Machine,Direct pressure mould opening and closing system, horizontal injection structure, it can adjust the mould faster, and control the position more precisely. It is more suitable for producing the LSR parts which can be automatically removed from the mould.
The main feature of the vertical LSR molding machine:
* Advanced sliding rail structure, which can reduce the oil pollution and make the machine works faster and steadier.
* Active pin valve-pattern nozzle sealing system, which can guarantee the injection more accurately.
* Meet the requirements on multi-station production.
* High-performance servo motor system is installed, which can guarantee the machine work more accurately and more energy-savingly.

LSR injection machine:vertical sliding /vertical rotary /horizontal etc.
Injection unit:
1. Square hydraulic motor:its position accuracy is ≤0.1MM;
2. Non-return valve between the motor and tube;
3. Bidirectional axial :positioning to avoid the wiggle of the screw；its swing accuracy is ≤0.05MM;
4. Barrel :LSR using ;spline design;pneumatic sealant shut-off nozzle;
5. Injection cylinder:one-piece casting ,its diameter is 5~10mm bigger than normal ;
6. Oil circuit: specially design for LSR, its storage position accuracy is ≤0.05MM;
7. Oil pump : aluminum jacketed oil seal that installs easily and locate well;Oil pump with bidirectional buffering,which moves smoothly;
8. Dorsal bracket ring: protect the O-ring;
9. Air cylinder :internal installed pneumatic sealing needle nozzle；electronic measuring ruler(Gefran-Italy)
10. Optional-Rexroth full closed loop servo valve .(real-time monitoring pressure, speed, back pressure and automatic feedback correction.)
The main feature of the double-material LSR molding machine:
* One common machine, two functions.
* Meet the requirements on double-material injection technology
* Save labor force, improve the efficiency and yield.
* Independent double injection system
* Satisfy the molding technology for both of the thermoplastic material and thermosetting material on one common machine
* The perfect combination on both of the plastic and LSR molding technology
