Moreover, the MP plastic blow molding machine supports multiple plastic materials such as PE, PP, PVC, PA, PC, PS, and EVA. It not only handles these different materials efficiently but also ensures an excellent molding process, resulting in high-quality finished products.

Features:

The extruding device features a variable frequency motor that accommodates the varying rotational speeds of the screw during the blowing process. Utilizing a screw with a high slenderness ratio enables the processing of a wide range of materials, offering robust plasticizing capabilities. This design ensures high production efficiency while maintaining low energy consumption. Additionally, the barrel uses a resistance heater managed by a computer system, which provides rapid, stable, and uniform heating.

By fitting different heads in the combined extrusion system placed between two extrusion machines, products with clear strip lines or double-layered structures can be manufactured. This flexibility allows for diverse product configurations according to specific requirements.

The mould clamping mechanism employs a toggle type and linear guider design. Featuring a double station, the mould platen moves with increased speed and enhanced stability, contributing to improved productivity and precision during operation.

An improved hydraulic oil circuit design results in power savings along with rapid and stable performance. The system is optimized for efficiency, ensuring smooth and consistent hydraulic operation.

Installation and maintenance of hydraulic components are made convenient by the inclusion of a removable and mobilizable oil tank. This design simplifies servicing and enhances overall machine upkeep.

The entire machine is controlled via a computer system, utilizing a hydraulic system with double proportional control. It features an automatic fault alarm, reliable operation, high automation levels, and memory storage for up to 40 sets of mould data, facilitating quick changeovers and minimizing downtime.

Operators can choose among three different modes: “Manual," “Semi-Auto," and “Full Auto," adapting the machine’s functionality to various operational needs and preferences.

Safety is ensured through an electric and mechanical safety door system that prevents mould closing if the door is open. This mechanism guarantees safe and reliable operation, protecting operators during use.

The machine supports two blowing cutting methods: straight cutting and oblique cutting. Both functions provide versatility in producing different product shapes and finishes.

Moreover, the oblique blowing function enhances the machine’s capability by allowing angled blowing processes, adding further flexibility to product design possibilities.

This section provides the fundamental details regarding the machine’s capacity and dimensions. The machine is compatible with materials such as PE and PP. It can handle a maximum product volume of 10 liters and comes equipped with three heads. The overall machine dimensions measure 3.5 meters in length, 5.6 meters in width, and 2.65 meters in height. The machine weighs 15 tons, indicating its robust construction.

The mould clamping system is designed for efficiency and strength. It features a mould clamping force of 200 KN, ensuring the mould is held firmly during operation. The platen has opening strokes adjustable between 240 mm to 640 mm, and the plate stroke extends up to 750 mm. The maximum mould size accommodated by this system is 700 mm in width by 420 mm in height.

The extrusion system specifications vary based on different screw sizes and configurations. The screw diameters range from 25 mm up to 100 mm, with slenderness ratios (L/D) mostly in the range of 22 to 26, which impacts the plasticizing efficiency. The system is capable of plasticizing high-density polyethylene (HDPE) at rates from 3 kg/h to 218 kg/h depending on the screw used. Heating is divided into multiple zones to ensure optimal temperature control, with screw heating power varying from 1.4 kW to 17.4 kW. The extrusion motor power ranges significantly from 1.5 kW to 55 kW to suit different operational needs.

The head component includes 14 heating stages or zones and is powered with a total heating capacity of 30 kW. This setup ensures precise temperature management during the extrusion process for consistent quality.

The overall energy consumption of the machine is detailed as follows: the total machine power is rated at 210 kW, with an additional oil motor power requirement of 31 kW. The machine operates under an air pressure ranging from 0.6 to 1 MPa, consuming compressed air at a volumetric rate of 1.2 cubic meters per minute. Cooling water is supplied at a rate of 1000 liters per minute to maintain optimal temperature control throughout the system.

Applications:

An extrusion molding machine is extensively utilized across various industries. It primarily serves to manufacture products from materials such as plastic, rubber, and others by means of the extrusion process. The machine finds diverse applications in several fields, including but not limited to:
