Heavy Duty Plastic Tool Box Blow Molding Machine

Product Description:

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 and continuous production of hollow plastic products, making it an ideal choice for demanding manufacturing environments.

Powered by an energy-efficient hydraulic system, the machine operates with precision and reliability. The integration of a dynamic microcomputer controller allows for precise regulation, ensuring consistent parison wall thickness and faster cycle times. These technological advancements contribute to enhanced productivity and product quality.

In addition to performance, the MP70FS prioritizes operator safety with advanced safety mechanisms incorporated into its design. As a result, it serves as a robust manufacturing platform tailored for smart factories aiming to maximize output while minimizing operational expenses.


Features:

Core Product Advantages & Features
1. High-Speed Double Station Shuttle Clamping

The product features a robust toggle-clamping system combined with high-quality linear guides, ensuring the mold platens move with exceptional stability and speed. This double-station shuttle design significantly reduces dry cycle times, enabling automated take-out lines to reach unparalleled daily throughput.

2. Intelligent Fluid Loop for Power Saving

The hydraulic system integrates a V4 dual pump with an electro-hydraulic proportional overflow speed regulating valve (PQ Valve). During high-speed movements, both pumps work together to provide the required flow. At low-speed, high-pressure lockup phases, the larger pump unloads, which significantly decreases electrical consumption and reduces fluid thermal stress.

3. Precise Flashing Control (Zero-Drift Clamping)

To prevent mold deflection during high-pressure inflation, the clamping cylinders include a specialized liquid control one-way valve (V12). This design hydraulically locks the circuit immediately after closing, effectively preventing part flashes and greatly enhancing the appearance of the parting line.

4. Smart Anti-Cold-Start Screw Safeguard

The frequency-changer-driven extrusion mechanism is electronically interlocked with multi-zone barrel heaters. The screw is prevented from rotating until all heating zones reach their designated processing temperatures, fully protecting the screw assembly from damage caused by un-melted plastic blockages.

5. Multi-Die Head Versatility with No Dead Angles

This system supports custom triple-head and multi-cavity co-extrusion crossheads. The internal melt path incorporates a streamlined diffluence shuttle that eliminates polymer stagnation and dead angles, avoiding defects such as dark spots or longitudinal stripes on the parison.

6. Clean Parison Hot Knife Shearing

Equipped with a pneumatic hot cutter blade heated by low-voltage, high-strength current supplied from an isolated transformer, the cutter cleanly and instantly slices through tough polymer parisons. This prevents tube collapse and layer smearing, ensuring a clean cut.

7. Automated Calibration with Smooth Neck Finish

The design incorporates an advanced down-blowing process where 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 that are prepared for downstream filling.

8. Category-4 Safety Door Interlocking Network

Operator safety is guaranteed through dual limit sensors and mechanical stroke switch loops on the safety guards. If the door is opened, it immediately triggers an automatic fault alarm and cuts off the output circuit to the clamping rams, providing a fail-safe protection mechanism.

Applications:

The MP70FS stands out for its exceptional versatility in processing various polyolefin resins. It is capable of handling materials such as PE, PP, PVC, PA, PC, PS, and EVA, enabling the production of structural components and parts with high strength and durability.

In the fast-moving consumer goods (FMCG) and rigid cosmetic packaging sectors, the MP70FS excels with its high-speed multi-cavity molding capabilities. This makes it ideal for manufacturing personal care containers including bottles, jars, and pots efficiently and reliably.

When it comes to industrial oils and chemicals, the MP70FS delivers precision molding needed for creating robust and long-lasting products. Examples include lubricant jugs, agrochemical containers, and stackable chemical barrels engineered to withstand demanding industrial environments.

The commercial hardware and cases market also benefits from the MP70FS’s technology. It produces high-impact, double-walled blow-molded cases for power tools and other rigid consumer product enclosures that require superior protection and durability.

Additionally, the MP70FS plays a crucial role in automotive sub-systems by manufacturing impermeable polyamide (PA) components such as air ducts, vehicle expansion tanks, and structural panels that contribute to vehicle performance and safety.
