Description
500-4000ton plastic injection molding machine for mid-sized/large-sized plastic parts
Designed to mold medium to large plastic parts efficiently, this two-platen injection molding machine integrates features that boost its performance and usability. The plastic injection molding machine uses low-friction linear guides for mold locking, speeding up both the mold opening and closing processes. A screw, specially designed with a high L/D ratio, enhances the plasticizing capabilities, allowing for consistent and effective molding. Linear guides support the lock mold and injection platform, reducing resistance and wear and providing smooth operation with precise mold locking accuracy of up to ±1%. This plastic injection machine handles clamping forces from 500 to 4000 tons, suitable for a wide range of molding tasks.

Key Components
Large pillar clamping system
Engineered for precise engagement and strong locking force, ensuring stable and reliable molding.
High-pressure cylinder design
Incorporates high-pressure cylinders and valves for even force distribution and robust lock mold force during injection processes.
Efficient hydraulic circuit
The system includes a high-pressure release for mold opening, which boosts the opening force and ensures smooth operations, alongside low-pressure protection to extend mold life.
Durable injection unit
Features a multi-axis drive mechanism that provides stability and precision throughout the injection process.
Removable Tie Bar Unit (Optional)
This feature overcomes factory height limitations and simplifies mold installation, especially for large molds that cannot be loaded from the top of the machine.
Moving Platen Support System
Specifically designed for two-platen machines, this moving platen support structure ensures the parallelism and accuracy of the platen's movement, even when heavy molds are mounted.
Clamping Unit
The platens are designed with the aid of Finite Element Method (FEM) analysis to ensure uniform force distribution across the machine and mold. This extends machine lifespan and enhances product quality.
Features
- The design includes durable structures from leading European manufacturers, enhancing the injection molding machine's longevity.
- Its compact lock mechanism reduces space requirements in factories by over 30%.
- Offers a large mold stroke and capacity, making it ideal for producing a wide variety of products, including large deep bucket-type items.
- Designed with minimal elbow-joint wear, the molding system requires less lubrication and reduces maintenance costs.
- a supplementary pressure cylinder maintains precise lock mold force within a ±1% error margin during injection.
