Double Station custom blow molding machine fully automatic model MP 100

Product Description:

The MP plastic blow molding machine is specifically designed for manufacturing a wide range of plastic hollow products made from high molecular materials. This versatile equipment excels in producing items that vary in size, from as small as 5 milliliters up to 100 liters.

It is widely used to create various hollow products such as bottles, pots, jars, barrels, toys, toolboxes, bed boards, desk boards, chairs, and even automotive parts. Its adaptability makes it suitable for numerous applications across different industries.

Moreover, the MP plastic blow molding machine supports processing multiple types of materials, including PE, PP, PVC, PA, PC, PS, and EVA. This wide compatibility ensures that manufacturers can achieve excellent results through an optimized production process.

Features:

The extruding device is equipped with a variable frequency motor that effectively meets the rotational requirements of the screw during the blowing process. The screw, characterized by a high slenderness ratio, is capable of processing a wide variety of materials. It offers strong plasticizing performance, ensuring high production efficiency while consuming low energy. Additionally, the barrel utilizes a resistance heater controlled by a computer, allowing for fast, stable, and uniform heating.

By installing different heads in the combined extrusion system between two extrusion machines, it is possible to produce blown products with visible strip lines or double-layer structures. This flexibility enhances the range of products that can be manufactured.

The mould clamping device features a toggle type mechanism and a linear guide. With a double station setup, the mould platen moves more quickly and smoothly, improving overall operational efficiency.

The hydraulic oil circuit has been improved for better power saving, rapid response, and stable performance. Installation and maintenance of hydraulic components are made convenient with a removable and mobilizable oil tank.

The entire machine is controlled via computer. Its hydraulic system uses double proportional control, enabling reliable operation with high automation levels. Furthermore, it includes an automatic fault alarm system and can store data for up to 40 sets of moulds.

Users can choose from three operational modes: "Manual," "Semi Auto," and "Full Auto," providing flexibility depending on the application requirements.

Safety is a priority, as evidenced by the safety door incorporating both electric and mechanical safety devices. This feature prevents mould closing when the safety door is open, making the operation safe and dependable.

The machine supports two blowing cutting functions: straight cutting and oblique cutting. Additionally, it includes an oblique blowing function to further extend its operational capabilities.

Technical Parameters:

The extrusion system consists of various screws with different diameters and their corresponding technical specifications. The screw diameters include 100mm, 75mm, and 25mm, each differing in slenderness ratio, plasticizing ability, heating zones, and power ratings.

The extrusion head is equipped with 14 heating zones, having a total heating power of 30 kW. This configuration ensures uniform temperature distribution during operation.

The machine's total power consumption is 210 kW, which includes the oil motor power of 31 kW. The system operates with an air pressure range between 0.6 and 1 MPa, consuming compressed air at 1.2 cubic meters per minute. Additionally, the cooling system requires a water flow rate of 1000 liters per minute to maintain optimal operational temperatures.

Applications:

Extrusion blow molding is widely used to manufacture a variety of hollow plastic containers. In the personal care and cosmetics sector, it produces items such as shampoo bottles, shower gel bottles, liquid soap bottles, and cosmetic containers. The chemical packaging field uses these machines to create lubricant bottles, pesticide containers, and chemical reagent bottles.

For food and beverage packaging, common products include milk bottles, juice bottles, and containers for edible oil, primarily made from HDPE. In the pharmaceutical industry, extrusion blow molding is employed to make medicine bottles and disinfectant bottles, mainly for non-sterile products.

The technology is also essential for producing large hollow containers like chemical drums and plastic barrels, ranging in size from 5 liters up to 200 liters. Automotive components such as fuel tanks, air ducts, and coolant tanks or fluid reservoirs are manufactured using extrusion blow molding. Additionally, it is utilized to create various equipment housings, including hollow cases and enclosures.

In agriculture, extrusion blow molding produces essential items such as pesticide sprayers, fertilizer containers, and water cans. It is also used for manufacturing hollow parts related to irrigation systems, providing durable and lightweight solutions for farm use.

This process is commonly used for consumer products like plastic toys, including hollow toys and balls. It also fabricates household items such as trash bins, storage containers, water tanks, and small reservoirs, contributing to everyday convenience and storage solutions.

Specialized extrusion blow molding products include multi-layer co-extrusion items like barrier bottles designed to prevent permeation and provide oxygen barriers. The technology supports recycled plastic products, which are typically non-food-grade containers made from recycled materials. Additionally, it facilitates the production of special material products with properties such as anti-static, chemical resistance, and flame retardancy.

Extrusion blow molding machines commonly process various materials. High-Density Polyethylene (HDPE) is the most frequently used. Other materials include Low-Density Polyethylene (LDPE) and Linear Low-Density Polyethylene (LLDPE), Polypropylene (PP), and Polyvinyl Chloride (PVC), although PVC use is restricted in certain regions. For specialized applications, materials like Ethylene Vinyl Acetate (EVA) and Polyamide (PA or Nylon) are also employed.

Extrusion blow molding machines are vital for manufacturing hollow plastic products. Their versatility and efficiency make them indispensable across various industries including packaging, chemical, automotive, agricultural, and consumer goods sectors, supporting a wide range of applications and materials.
