Furthermore, the MP blow molding machine supports processing of multiple materials such as PE, PP, PVC, PA, PC, PS, and EVA. It ensures an excellent molding process, delivering high-quality results for diverse material requirements.

Features:

The extruding device is equipped with a variable frequency motor, enabling it to meet the demands of screw rotation changes during the blowing process. The screw, characterized by a high slenderness ratio, is capable of processing a wide range of materials. It boasts excellent plasticizing ability, high production efficiency, and low energy consumption. Additionally, the barrel utilizes a resistance heater controlled by a computer system, ensuring rapid, stable, and even heating.

By installing different heads within the combined extrusion system that connects two extrusion machines, this setup can produce blown products featuring visual strip lines or double-layer structures. This versatility enhances the range of products that can be manufactured.

The mould clamping device employs a toggle mechanism alongside a linear guider. Featuring a double station design, it allows the mould platen to move rapidly and with enhanced stability, contributing to improved operational efficiency.

The hydraulic oil circuit has been improved for energy efficiency, delivering fast response times and stable performance. The design focuses on power saving without compromising operational reliability.

Installation and maintenance of hydraulic components are made easy thanks to the inclusion of a removable and mobile oil tank. This feature facilitates convenient servicing and upkeep of the system.

The entire machine is controlled via a computer, and its hydraulic system uses double proportional control technology. It features an automatic fault alarm system, ensuring reliable operation. Moreover, the machine supports high automation levels and can store data for up to 40 different moulds.

Operators can select from three different modes of operation: “Manual," “Semi-Auto," and “Full Auto," providing flexibility depending on production requirements.

For safety, the machine is equipped with an electric and mechanical safety door mechanism. This system prevents the mould from closing when the safety door is open, ensuring safe and reliable operation at all times.

The machine supports two blowing cutting functions: straight cutting and oblique cutting. These options allow for diverse processing capabilities to meet various application needs.

Additionally, the machine is equipped with an oblique blowing function, further expanding its operational versatility.

Technical Parameters:

The system is compatible with materials such as PE (Polyethylene) and PP (Polypropylene). The maximum product volume is designed to be up to 10 liters. The equipment features three heads for simultaneous operation. The machine dimensions measure 3.5 meters in length, 5.6 meters in width, and 2.65 meters in height, with an overall weight of 15 tons.

The mould clamping system exerts a force up to 200 kiloNewtons, ensuring stable and secure clamping during operation. The platen opening stroke ranges from 240 to 640 millimeters, allowing flexible adjustment. The plate has a stroke length of 750 millimeters. The maximum mould size accommodated is 700 by 420 millimeters (width x height).

The extrusion system consists of screws varying in diameter and slenderness ratio to adapt to different production demands. The plasticizing capacity with HDPE material varies accordingly, with screw heating stages and power tailored to achieve optimal melting and consistency.

The extrusion head features 14 heating zones to precisely control temperature during operation, with a total heating power of 30 kW to maintain consistent output quality.

The machine has a total power consumption of 210 kW. The oil motor requires 31 kW, while the compressed air system operates at a pressure between 0.6 and 1 MPa, with an air volume of 1.2 cubic meters per minute. The cooling water flow rate is maintained at 1000 liters per minute to ensure optimal temperature control during operation.

Applications:

Extrusion blow molding technology is widely utilized in the production of various hollow plastic containers. In the personal care and cosmetics sector, it is used to manufacture containers such as shampoo bottles, shower gel bottles, liquid soap bottles, and a range of cosmetic containers.

In the realm of chemical packaging, products like lubricant bottles, pesticide containers, and chemical reagent bottles are commonly produced using this method. For food and beverage packaging, extrusion blow molding is employed to create milk bottles, juice bottles, and edible oil containers, primarily utilizing high-density polyethylene (HDPE).

The pharmaceutical industry also benefits from this technology by producing medicine bottles and disinfectant bottles, particularly for non-sterile products.

The manufacturing of large hollow containers such as chemical drums and plastic barrels, ranging from 5 to 200 liters in capacity, relies heavily on extrusion blow molding. Additionally, this technology is applied in creating automotive components, including fuel tanks, air ducts, coolant tanks, and various fluid reservoirs.

It also serves in fabricating equipment housings, which include hollow cases and enclosures essential for protecting industrial machinery and electronics.

In agriculture, extrusion blow molding is instrumental in producing pesticide sprayers, fertilizer containers, and water cans. It is also used to create hollow parts related to irrigation systems, contributing to efficient water management and crop care.

The technology extends into consumer goods by manufacturing plastic toys such as hollow toys and balls. It is also used in making practical household items like trash bins, storage containers, water tanks, and smaller reservoirs, offering durability and convenience for everyday use.

Extrusion blow molding is capable of producing advanced multi-layer co-extrusion products, including barrier bottles designed to prevent permeation and provide oxygen barriers. Additionally, this process supports the creation of recycled plastic items, specifically non-food-grade containers made from recycled materials.

Specialized materials are also processed, enabling the production of plastics with properties such as anti-static behavior, chemical resistance, and flame retardancy, which are important for niche applications.

The materials most frequently used in extrusion blow molding include high-density polyethylene (HDPE), which is the predominant choice. Other materials include low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), polypropylene (PP), and polyvinyl chloride (PVC), although PVC use is restricted in certain regions. For specialized products, materials like ethylene-vinyl acetate (EVA) and nylon (PA) are also utilized.

Extrusion blow molding machines are vital for producing a wide array of hollow plastic products. They hold a central position in industries such as packaging, chemicals, automotive, agriculture, and consumer goods, enabling efficient and versatile manufacturing solutions.
