HDPE Industrial Bottle Extrusion Blow Molding Machine with Double Station Toggle

The MP70FS represents the pinnacle of industrial-grade blow molding technology as a flagship double station extrusion machine. Designed specifically for the efficient production of hollow plastic products, it excels in delivering consistent, high-quality output suitable for demanding manufacturing environments.

Powered by an energy-efficient hydraulic system, the MP70FS optimizes power consumption without compromising performance. Its operations are precisely controlled through an advanced dynamic microcomputer, ensuring seamless process management and enhanced product uniformity, particularly in maintaining consistent parison wall thickness.

Safety is a top priority with the MP70FS, featuring robust protective measures that ensure exceptional operator protection. This machine stands out as the ideal solution for smart factories aiming to increase production throughput while simultaneously minimizing overall operational expenses.

• High-Speed Double Station Shuttle Clamping
  Constructed with a robust toggle-clamping framework and top-quality linear guides, the mold platens move with remarkable stability and speed. This dual-station setup effectively reduces dry cycle times, enabling automatic take-out lines to reach unparalleled daily production rates.
• Intelligent Fluid Loop for Power Saving
  The hydraulic system integrates a V4 dual pump alongside an electro-hydraulic proportional overflow speed regulating valve (PQ Valve). For high-speed operations, both pumps work together to provide necessary flow. During low-speed, high-pressure locking phases, the large pump unloads, significantly reducing electricity consumption and minimizing thermal stress on the fluid.
• Precise Flashing Control (Zero-Drift Clamping)
  To prevent mold deformation under high-pressure inflation, a specialized liquid control one-way valve (V12) is installed within the clamping cylinders. This feature hydraulically locks the circuit immediately after closing, eliminating part flashing and greatly enhancing the appearance of parting lines.
• Smart Anti-Cold-Start Screw Safeguard
  The frequency-converter extrusion drive is electronically interlocked with multi-zone barrel heaters. The screw remains stationary until all heating zones fully reach their designated processing temperatures, thereby safeguarding the screw assembly from damage caused by unmelted plastic blockages.
• Multi-Die Head Versatility with No Dead Angles
  This system supports customized triple-head and multi-cavity co-extrusion crossheads. Its internal melt path incorporates a streamlined diffluence shuttle that eliminates polymer stagnation points (dead angles), preventing defects such as dark spots or longitudinal stripes on the parison.
• Clean Parison Hot Knife Shearing
  Equipped with a pneumatic hot cutter blade, heated by low-voltage, high-strength current supplied via an isolated transformer, it cleanly and instantly slices through resilient polymer parisons. This mechanism prevents tube collapse and avoids layer smearing during cutting.
• Automated Calibration with Smooth Neck Finish
  Employing an advanced down-blowing technique, the blow pin tip and mold neck ring automatically trim and calibrate the container neck throughout the inflation cycle. This process ensures a perfectly flat, burr-free sealing surface that is ready for subsequent filling on the production line.
• Category-4 Safety Door Interlocking Network
  Operator safety is guaranteed through dual limit sensors and mechanical stroke switch loops integrated within the safety guards. Opening the door instantly triggers an automatic fault alarm and interrupts the output circuit to the clamping rams, offering reliable fail-safe protection.

The MP70FS machine delivers unparalleled flexibility in processing a wide range of polyolefin materials. It is capable of handling various resins such as PE, PP, PVC, PA, PC, PS, and EVA. This versatility enables the production of structural and high-strength components suitable for numerous applications.
