Core Product Advantages & Features
1. High-Speed Double Station Shuttle Clamping
Featuring a durable toggle-clamping structure paired with high-quality linear guides, the mold platens move with outstanding stability and speed. This innovative double-station design significantly reduces dry cycle times, enabling automatic take-out systems to reach unparalleled daily production rates.
2. Intelligent Fluid Loop for Power Saving
The hydraulic system integrates a V4 dual pump alongside an electro-hydraulic proportional overflow valve (PQ Valve) to regulate speed. During fast movements, both pumps work together to provide high flow, while in low-speed, high-pressure locking phases, the larger pump unloads. This strategy effectively decreases electricity usage and reduces thermal stress on the fluid.
3. Precise Flashing Control (Zero-Drift Clamping)
To prevent mold deformation under high-pressure inflation, a specialized one-way liquid control valve (V12) is incorporated within the clamping cylinders. This valve hydraulically locks the circuit after closing, eliminating part flashes and greatly enhancing the appearance of the parting line.
4. Smart Anti-Cold-Start Screw Safeguard
The extrusion drive, controlled by a frequency changer, is electronically linked with multiple barrel heating zones. The screw rotation is inhibited until all heating areas reach the necessary processing temperatures, providing complete protection against damage caused by unmelted plastic blockages.
5. Multi-Die Head Versatility with No Dead Angles
The system supports customized triple-head as well as multi-cavity co-extrusion crossheads. Its internal melt passage includes a streamlined diffluence shuttle that eliminates polymer stagnation or "dead angles," preventing defects such as dark spots or longitudinal streaks on the parison.
6. Clean Parison Hot Knife Shearing
Equipped with a pneumatic hot knife blade heated by a low-voltage, high-strength current supplied from an isolated transformer, this feature allows for precise and instantaneous cutting of robust polymer parisons, avoiding tube collapse or layer smearing.
7. Automated Calibration with Smooth Neck Finish
Utilizing an advanced downward-blowing technique, the blow pin tip and mold neck ring automatically trim and calibrate the container neck during inflation. This process ensures consistently flat, burr-free sealing surfaces ideal for subsequent filling operations.
8. Category-4 Safety Door Interlocking Network
Operator safety is assured through dual limit sensors combined with mechanical stroke switch loops on safety guards. Opening the door immediately triggers a fault alarm and cuts power to the clamping rams, providing reliable fail-safe protection.
