MP70FS Down Blowing Extrusion Blow Molder With Smooth Neck Trimming

The extruding device is equipped with a variable frequency motor, allowing it to accommodate the varying rotation speeds of the screw during the blowing process. A screw with a high slenderness ratio can be utilized to handle a wide range of materials, offering strong plasticizing capabilities, high production efficiency, and low energy consumption. Additionally, the barrel features a resistance heater controlled by a computer, ensuring rapid, stable, and even heating.

By installing different heads within the combined extrusion system that connects two extrusion machines, the equipment is capable of producing products with visual strip lines or double layers. This flexibility enhances the variety of products that can be manufactured.

The mould clamping device incorporates a toggle mechanism and linear guides, utilizing a double station design. This configuration allows the mould platen to move more quickly and with greater stability, improving overall operational performance.

An improved hydraulic oil circuit has been developed to deliver energy savings, faster response, and increased stability. Furthermore, the installation and maintenance of hydraulic components are made convenient by the inclusion of a removable and mobile oil tank.

The entire machine operates under computer control, with the hydraulic system employing dual proportional control for precision. The machine features automatic fault alarms, reliable operations, high levels of automation, and the capability to store data for up to 40 different moulds.

Operators can choose from three distinct modes of operation: "Manual," "Semi Auto," and "Full Auto," providing flexibility to match different production needs and preferences.

For safety, the machine is equipped with electric and mechanical safety devices on the safety door. These mechanisms prevent the mould from closing when the safety door is open, ensuring a safe and reliable working environment.

Additionally, the machine includes an oblique blowing function, further enhancing its operational capabilities and the scope of products it can manufacture.

The machine is designed to handle a variety of materials including PE, PP, PVC, PA, and more. It supports a maximum product volume of up to 10 liters.

The equipment can be configured with 1 to 4 heads depending on the production requirements. Its overall dimensions measure 3.7 meters in length, 3 meters in width, and 2.5 meters in height. The total machine weight is approximately 8 tons.

The mould clamping system provides a force of 150 kiloNewtons, ensuring secure and reliable clamping during operation. The platen can open with a stroke range from 240 to 600 millimeters, and the plate stroke is 360 millimeters. The maximum mould size supported is 500 millimeters wide by 360 millimeters high.

The screw diameter used in the extrusion system is 70 millimeters, with a slenderness ratio (L/D) of 24. It has a plasticizing capacity of 90 kilograms per hour when processing HDPE material.

The screw heating is divided into 3 stages or zones, powered by 12 kilowatts of energy. Additionally, the screw cooling fan consumes 0.28 kilowatts. The extrusion motor has a power rating of 18.5 kilowatts.

The head component includes 10 heating zones with a total heating power of 16.5 kilowatts. It accommodates a maximum extrusion gate mould diameter of 3 millimeters.

The total power consumption of the machine is rated at 70 kilowatts. The oil motor consumes 15 kilowatts while the average operating energy consumption is approximately 1.5 kilowatts.

The system operates with an air pressure range from 0.6 to 0.8 megapascals and requires a compressed air volume of 50 cubic meters per hour. Cooling water consumption is set at 55.5 cubic meters per hour to maintain optimal operation temperatures.

Implementing regular preventive maintenance is crucial for plastic molding factories. These essential routine servicing checklists help ensure that all machinery and equipment operate smoothly, minimizing unexpected downtime and enhancing overall production efficiency.

Official SOPs serve as comprehensive training manuals designed for technical adjusters and line operators. These guides provide step-by-step instructions to maintain consistency, safety, and quality in daily operations on the factory floor.

Effective management of equipment lifecycle is vital for prolonging the functionality of heavy-duty extrusion screws and hydraulic pump systems. By adopting strategic maintenance and operational practices, factories can maximize the service life of critical machinery components.
