800t Injection Moulding Machine Equipment

 Primary Performance and Features of Longhua Die Casting Machines

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 without 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 effectively controls filling time and casting formation. It includes unique braking and uniform acceleration injection functions that prevent flash and allow flexible injection processes.
B. Minimum speed 0.1–0.7 m/s, which can be precisely controlled to prevent air invasion and air traps.
C. Pressure building time ≤ 15 m/s, allowing adjustment of pressure building speed based on process requirements, enhancing casting density without causing 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%, and productivity improved by 20% compared to previous models.
4. International PLC man-machine interface control system with data storage and monitoring capabilities, timely alarms for abnormalities, and elimination of large quantities of defective products.
5. Unique static and dynamic performance with dual core-pulling devices ensures precise and complex products in one step.
6. Injection system uses European draw-bar structure, offering multiple options for center and eccentric injection positions, easy adjustment, high precision, and applicability 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, providing longer service life and faster production, with shift output increased by over 15%.
9. Liquid nitrogen super low temperature installation method ensures precision and prolongs toggle part service life.
10. High-quality, high-rigidity, and wear-resistant casting platen uses finite element analysis 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 are well-known brands from Europe, Japan, and Taiwan.
13. Die-casting unit island design offers various interfaces and software packages for advanced intelligent peripheral devices.
14. Hydraulic system consists of the most advanced uniform accelerated multi-stage injection system in the world.
