800t Injection Moulding Machine Equipment

 Primary performance and features of Longhua Die Casting machine

1. Double proportional control (electric regulation of pressure and flow, with multi-level pressure and speed control, and low pressure die close protection functions).
2. Dual circuit design (air injection and pressure building are separately designed, no mutual interference or faults).
3. Four-stage (multi-stage) injection system:
A. Maximum speed > 8 m/s (6 m/s for those over 2000T), which can effectively control filling time and casting formation, with unique braking and uniform acceleration injection function that prevents flash and allows flexible injection process.
B. Minimum speed 0.1–0.7 m/s, precisely controlled to prevent air invasion causing air traps.
C. Pressure building time ≤15 m/s, allowing adjustment of pressure building speed according to process needs, increasing casting density without product distortion.
D. Dry cycle time reduced by over 15%; Oil pump flow increased by over 20%; Cooler capacity enhanced by over 100%; Conforming finished products increase by 100%; Productivity improved by 20% compared to past.
4. International PLC man-machine interface control system, capable of storing and monitoring casting product data, timely alarm in case of abnormalities, and eliminating large quantities of defective products.
5. Unique static and dynamic performance with dual core-pulling devices ensures precise, complex products in one go.
6. Injection system uses European draw-bar structure with multiple center and eccentric injection positions for easy adjustment, high precision, and adaptability to various complex molds.
7. Large-scale die-casting machines above 1600T use hydraulic pumping for safe and fast mold replacement.
8. Independent quick clamping system and unique hydraulic driven gear-type mold height adjusting mechanism resist impact, offering longer service life and faster production, increasing shift output by over 15%.
9. Liquid nitrogen super low temperature installation method ensures precision and extends toggle part service life.
10. High-quality, high rigidity, and wear-resistant casting platen with finite element analysis design for even stress distribution, minimal distortion, and accurate mold clamping.
11. Electric central lubrication system provides scheduled, quantitative lubrication and improves service life.
12. Electrical and hydraulic components from well-known brands in Europe, Japan, and China Taiwan.
13. Die-casting unit island design offers various interfaces and software packages for advanced intelligent peripheral devices.
14. Hydraulic system includes the most advanced uniform accelerated multistage injection system in the world.
