Energy Saving Hydraulic Extrusion Blow Molding Machine

The MP70FS stands as a premier industrial-grade extrusion blow molding machine, designed with dual stations to optimize production efficiency. This advanced equipment is specifically engineered for the continuous manufacturing of hollow plastic products, making it ideal for high-demand industrial environments.

Equipped with an energy-efficient hydraulic system and controlled by an intelligent microcomputer, the MP70FS ensures outstanding cycle speeds and consistently uniform parison wall thickness. These features contribute to superior product quality while enhancing operational reliability.

In addition to its performance capabilities, the MP70FS prioritizes operator safety through its advanced design and control mechanisms. As a result, it serves as the ultimate manufacturing solution for smart factories aiming to boost output and minimize overall operational expenses.

• High-Speed Double Station Shuttle Clamping
  Constructed with a sturdy toggle-clamping framework and high-quality linear guides, the mold platens operate with exceptional stability and rapid movement. This double-station design significantly reduces dry cycle times, enabling automatic take-out systems to reach unparalleled daily production rates.
• Intelligent Fluid Loop for Power Saving
  The hydraulic system integrates a V4 dual pump paired with an electro-hydraulic proportional overflow speed regulating valve (PQ Valve). During high-speed travel, both pumps deliver combined flow, while in low-speed, high-pressure lockup scenarios, the larger pump unloads. This approach considerably decreases electrical consumption and minimizes thermal stress on the fluid.
• Precise Flashing Control (Zero-Drift Clamping)
  To prevent mold deflection under high-pressure inflation, a specialized liquid control one-way valve (V12) is embedded within the clamping cylinders. This valve hydraulically locks the circuit after closing, effectively eliminating part flashes and significantly enhancing the appearance of the parting line.
• Smart Anti-Cold-Start Screw Safeguard
  The frequency-changer extrusion drive is electronically linked with multi-zone barrel heaters, ensuring the screw remains stationary until all heating zones reach their optimal processing temperatures. This interlock mechanism fully protects the screw assembly from damage caused by unmelted plastic blockages.
• Multi-Die Head Versatility with No Dead Angles
  This system supports custom triple-head and multi-cavity co-extrusion crossheads. Its internal melt path features a streamlined diffluence shuttle, eliminating polymer stagnation or dead angles, thereby 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 from an isolated transformer, the device cleanly and instantly slices through tough polymer parisons. This process helps prevent tube collapse and layer smearing during cutting.
• Automated Calibration with Smooth Neck Finish
  Utilizing an advanced down-blowing technique, 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, which are ready for subsequent post-line filling operations.
• Category-4 Safety Door Interlocking Network
  Operator safety is guaranteed through the use of dual limit sensors and mechanical stroke switch loops integrated into the safety guards. When the door is opened, an automatic fault alarm is triggered immediately, and the output circuit to the clamping rams is interrupted, providing a fail-safe protection mechanism.

• Material Processing: The MP70FS provides exceptional versatility in processing polyolefin materials. It is capable of handling a wide range of resins such as PE, PP, PVC, PA, PC, PS, and EVA. This flexibility enables the production of structural and high-strength components across various industries.
• Consumer Goods Packaging: In the Fast-Moving Consumer Goods (FMCG) and rigid cosmetic packaging sectors, the MP70FS excels with its high-speed multi-cavity molding capabilities. It is ideal for manufacturing personal care containers including bottles, jars, and pots that require precision and durability.
• Industrial Chemical Containers: For the industrial oils and chemicals market, this machine delivers precise molding performance essential for creating reliable and sturdy lubricant jugs, agrochemical containers, and stacked chemical barrels. Its accuracy ensures that products meet stringent industry standards.
• Hardware and Protective Cases: Within the commercial hardware and cases category, the MP70FS produces high-impact, double-walled blow-molded cases. These include power tool cases and rigid enclosures designed to protect consumer products, combining strength with functional design.
• Automotive Components: Additionally, the MP70FS is well-suited for automotive sub-systems. It manufactures impermeable polyamide (PA) components such as air ducts, vehicle expansion tanks, and structural panels, contributing to improved vehicle performance and reliability.
