Double Station Toggle Blow Molding Machine with Variable Frequency Motor and Centralized Microcomputer Control

The MP70FS stands as a premier industrial-grade extrusion blow molding machine, featuring a double station design. It is specifically engineered to support high-efficiency production, enabling continuous manufacturing of hollow plastic products with precision and reliability.

Powered by an energy-efficient hydraulic system and controlled through an advanced dynamic microcomputer, the MP70FS ensures outstanding cycle speeds. This technology also maintains consistent parison wall thickness, which is critical for producing uniform and high-quality plastic items.

Beyond performance, the machine prioritizes operator safety, incorporating features that protect personnel during operation. As a result, it serves as the ideal manufacturing solution for smart factories aiming to enhance throughput while minimizing overall operational costs.

• High-Speed Double Station Shuttle Clamping: Constructed with a durable toggle-clamping mechanism and high-quality linear guides, the mold platens move with remarkable stability and speed. This dual-station design effectively reduces dry cycle times, enabling automatic take-out lines to reach unprecedented levels of daily productivity.
• Intelligent Fluid Loop for Power Saving: The hydraulic system incorporates a V4 dual pump paired with an electro-hydraulic proportional overflow speed regulating valve (PQ Valve). When high-speed travel is required, both pumps work together to provide flow. During slower, high-pressure locking phases, the larger pump unloads, significantly reducing electricity consumption and thermal stress on the hydraulic fluid.
• Precise Flashing Control (Zero-Drift Clamping): To prevent mold deflection under high-pressure conditions, a specialized one-way liquid control valve (V12) is installed within the clamping cylinders. This hydraulic lock secures the circuit immediately after closing, eliminating part flashes and greatly enhancing the aesthetic quality of the parting line.
• Smart Anti-Cold-Start Screw Safeguard: The extrusion drive, powered by a frequency converter, is electronically interlocked with multi-zone barrel heaters. This setup ensures the screw cannot rotate until all heating zones reach the designated processing temperatures, fully protecting the screw assembly from damage caused by unmelted plastic blockages.
• Multi-Die Head Versatility with No Dead Angles: Supporting custom triple-head and multi-cavity co-extrusion crossheads, the internal melt path is designed with a streamlined diffluence shuttle. This innovation eliminates polymer stagnation areas, known as dead angles, thereby preventing dark spots or longitudinal stripes on the parison surface.
• Clean Parison Hot Knife Shearing: The system features a pneumatic hot cutter blade heated by a low-voltage, high-strength current from an isolated transformer. This equipment instantly and cleanly slices through tough polymer parisons, avoiding tube collapse and layer smearing.
• Automated Calibration with Smooth Neck Finish: Utilizing an advanced down-blowing process, the blow pin tip and mold neck ring automatically trim and calibrate the container neck during inflation. This ensures perfectly flat and burr-free sealing surfaces, ready for efficient post-line filling operations.
• Category-4 Safety Door Interlocking Network: Operator safety is prioritized through dual limit sensors and mechanical stroke switch loops integrated into the safety guards. Opening the door immediately triggers an automatic fault alarm and interrupts the output circuit to the clamping rams, providing a fail-safe protection mechanism.

The MP70FS provides exceptional versatility in processing a wide range of polyolefin resins, including PE, PP, PVC, PA, PC, PS, and EVA. This capability enables the production of structural and high-strength components suited for various industries.

In the fast-moving consumer goods (FMCG) and rigid cosmetic packaging sector, the MP70FS supports high-speed multi-cavity molding. This is ideal for manufacturing personal care containers such as bottles, jars, and pots with precision and efficiency.

For industrial oils and chemicals, the machine ensures precise molding of robust lubricant jugs, agrochemical containers, and stacking chemical barrels, enhancing durability and reliability in demanding environments.

Within the commercial hardware and cases market, the MP70FS produces high-impact, double-walled blow-molded power tool cases and rigid enclosures for consumer products, offering excellent protection and strength.

When it comes to automotive sub-systems, this equipment creates impermeable polyamide (PA) components, including air ducts, vehicle expansion tanks, and structural panels, contributing to enhanced vehicle performance and longevity.
