Triple Die Head Double Station Extrusion Blow Molding Machine MP70FS

Product Description:

The MP70FS represents a premier industrial-grade double station extrusion blow molding machine designed to achieve high-efficiency and continuous production of plastic hollow products. Its robust construction and advanced features make it an ideal choice for demanding manufacturing environments.

Powered by an energy-efficient hydraulic system and precisely controlled through a dynamic microcomputer, the MP70FS ensures rapid cycle times while maintaining consistent parison wall thickness. This combination guarantees both productivity and product quality at every stage of the manufacturing process.

Furthermore, the machine prioritizes operator safety with exceptional protective measures integrated into its design. As a result, the MP70FS serves as a cutting-edge manufacturing solution, perfectly suited for smart factories aiming to enhance throughput and minimize overall operational expenses.

Features:

This system is built with a robust toggle-clamping framework combined with premium linear guides, ensuring the mold platens move with remarkable stability and high speed. The innovative double-station design significantly reduces dry cycle times, enabling automatic take-out lines to reach exceptional daily throughput rates.

The hydraulic core integrates a V4 dual pump alongside an electro-hydraulic proportional overflow speed regulating valve (PQ Valve). During high-speed movement, both pumps operate in unison to maximize flow, while in low-speed, high-pressure lockup phases, the larger pump unloads. This efficient design substantially cuts electric consumption and minimizes fluid thermal stress.

To prevent mold deflection during intense high-pressure inflation, a specialized liquid control one-way valve (V12) is incorporated within the clamping cylinders. This hydraulic locking mechanism secures the circuit after closing, effectively eliminating part flashes and greatly enhancing the appearance of the parting line.

Featuring a frequency-changer extrusion drive electronically linked to multi-zone barrel heaters, this system prevents screw rotation until all heating zones have reached their required processing temperatures. This interlock thoroughly protects the screw assembly from damage caused by un-melted plastic blockages.

Supporting customized triple-head and multi-cavity co-extrusion crossheads, the internal melt path includes a streamlined diffluence shuttle. This design eliminates polymer stagnation areas, commonly known as dead angles, preventing defects such as dark spots or longitudinal stripes on the parison.

Equipped with a pneumatic hot cutter blade powered by low-voltage, high-strength current from an isolated transformer, this feature allows for instant and clean slicing of tough polymer parisons. It helps avoid tube collapse and layer smearing during the cutting process.

Utilizing 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 ensures perfectly flat, burr-free sealing surfaces that are ready for subsequent filling operations.

Operator safety is prioritized with dual limit sensors and mechanical stroke switch loops installed on the safety guards. Opening the safety door triggers an immediate fault alarm and cuts power to the clamping rams, providing reliable fail-safe protection.

Applications:

The MP70FS machine delivers exceptional versatility when working with a wide range of polyolefin materials. It is compatible with resins such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamide (PA), polycarbonate (PC), polystyrene (PS), and ethylene-vinyl acetate (EVA). This extensive resin compatibility enables the production of durable and high-strength structural components across various industries.

In the Fast-Moving Consumer Goods (FMCG) and rigid cosmetic packaging sectors, the MP70FS excels by enabling high-speed, multi-cavity molding. This capability is ideal for manufacturing personal care containers like bottles, jars, and pots with consistent quality and efficiency.

Within the industrial oils and chemicals market, the machine ensures precision molding of robust items such as lubricant jugs, agrochemical containers, and stackable chemical barrels. This precision guarantees the functionality and durability required for demanding industrial applications.

For commercial hardware and cases, the MP70FS is used to produce high-impact, double-walled blow-molded cases for power tools and rigid enclosures for consumer products. These sturdy components provide reliable protection and longevity for their contents.

In the automotive sub-systems arena, the MP70FS supports the manufacturing of impermeable polyamide (PA) air ducts, vehicle expansion tanks, and structural panels. These parts contribute to vehicle performance and safety, leveraging the machine's ability to process high-performance materials.
