It offers strong plasticizing ability, high production output, and low energy consumption. Additionally, the barrel is equipped with a resistance heater controlled by a computer, ensuring rapid, stable, and uniform heating.

By installing different heads within a combined extrusion system that connects two extrusion machines, it is possible to manufacture products featuring visible strip lines or double layers. This flexibility allows for diverse product designs and enhances the functionality of the machinery.

The mold clamping device incorporates a toggle-type mechanism along with a linear guide. It features a double station design, which enables the mold platen to move faster and more steadily, improving operational efficiency and product consistency.

An improved hydraulic oil circuit has been implemented, resulting in power savings along with rapid and stable hydraulic performance. The system's installation and maintenance are user-friendly, facilitated by a removable and movable oil tank.

Full machine control is managed through a computerized system, with the hydraulic system employing double proportional control. The machine includes an automatic fault alarm system, ensuring reliable operation, high automation, and the capability to store data for up to 40 sets of molds.

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

For enhanced safety during operation, the machine is equipped with safety doors that incorporate both electrical and mechanical safety devices. This design prevents mold closing when the safety door is open, making the operation safe and dependable.

The machine supports two blowing functions: straight cutting and oblique cutting, allowing for versatile processing options to meet various product specifications.

Additionally, the machine is equipped with an oblique blowing feature, further expanding its functional capabilities.

Technical Parameters:

The machine is designed to handle specific types of materials, including Polyethylene (PE) and Polypropylene (PP). It supports a maximum product volume of up to 10 liters. The setup includes three heads, allowing for efficient multi-head operation.

The overall dimensions of the machine measure 3.5 meters in length, 5.6 meters in width, and 2.65 meters in height. The total weight of the machine is approximately 15 tons, reflecting its robust construction.

Equipped with a mould clamping system, the machine can exert a clamping force of 200 kN. The platen opening stroke varies between 240 mm to 640 mm, providing flexible operation. Additionally, the plate stroke extends up to 750 mm to accommodate various mould sizes.

The maximum allowable mould dimensions are 700 mm in width and 420 mm in height, which supports a wide range of mould configurations for diverse product designs.

The extrusion system features screws with varying diameters, including 100 mm, 75 mm, and 25 mm, tailored for different processing requirements. Corresponding screw slenderness ratios range from 22 to 26 L/D, optimizing plasticizing efficiency.

When processing High-Density Polyethylene (HDPE), the plasticizing capacities are specified as 218 kg/h for the largest screw and 3 kg/h for the smallest. The number of heating zones per screw ranges from 2 to 4, with heating power levels from 1.4 kW to 17.4 kW. Screw fans and extrusion motors also vary in power, supporting precise temperature control and material throughput.

The machine head includes 14 heating zones powered by a 30 kW heating system, ensuring uniform material flow and quality during extrusion.

The total machine power consumption is 210 kW, encompassing all operational components. The oil motor requires 31 kW, while the air pressure system operates between 0.6 to 1 MPa. The compressed air volume intake is approximately 1.2 cubic meters per minute.

For cooling, the system uses water at a flow rate of 1000 liters per minute, maintaining optimal operating temperatures throughout the process.

Applications:

Extrusion blow molding machines are extensively used in the production of various hollow plastic containers across multiple sectors. In the personal care and cosmetics industry, they manufacture items such as shampoo bottles, shower gel containers, liquid soap bottles, and other cosmetic packaging.

In the chemical sector, these machines produce lubricant bottles, pesticide containers, and chemical reagent bottles. Additionally, food and beverage packaging relies on them for milk bottles, juice containers, and edible oil packaging, primarily using HDPE materials. The pharmaceutical industry also benefits from extrusion blow molding for producing medicine bottles and disinfectant containers, particularly for non-sterile products.

Large hollow containers such as chemical drums and plastic barrels ranging from 5 to 200 liters are commonly produced using extrusion blow molding. The automotive industry also utilizes this technology for fabricating components including fuel tanks, air ducts, coolant tanks, and various fluid reservoirs. Moreover, equipment housings in the form of hollow cases and enclosures are manufactured using these machines.

In agriculture, extrusion blow molding is employed to create pesticide sprayers, fertilizer containers, water cans, and various irrigation-related hollow parts. These components are essential for efficient agricultural practices and resource management.

The technology is also vital in producing consumer goods like plastic toys, including hollow toys and balls. Household items such as trash bins, storage containers, water tanks, and small reservoirs are manufactured through extrusion blow molding processes.

Extrusion blow molding machines are capable of producing multi-layer co-extrusion products, including barrier bottles designed to prevent permeation and provide oxygen barriers. Additionally, they process recycled plastic materials to produce non-food-grade containers. Special material variants such as anti-static, chemical-resistant, and flame-retardant plastics are also fabricated for specific industrial needs.

These machines generally handle a variety of plastic materials including HDPE (High-Density Polyethylene), which is the most commonly used. Other materials include LDPE, LLDPE, and PP (Polypropylene). PVC is also processed, though its use is restricted in some regions. For specialized applications, materials like EVA and PA (Nylon) are utilized.

Overall, extrusion blow molding machines are indispensable for producing hollow plastic products across diverse industries. They play a crucial role in packaging, chemical manufacturing, automotive parts production, agriculture, and consumer goods, enabling efficient and versatile plastic container and component fabrication.
