3set Number of heads Economical Automatic Blow Moulding Machine

Product Description:

The MP plastic blow molding machine is designed specifically for manufacturing various types of plastic hollow products made from high molecular materials. This advanced machine is capable of producing hollow items with capacities ranging from as small as 5 milliliters up to large sizes of 100 liters.

Its versatility allows it to create a wide array of products including bottles, pots, jars, barrels, toys, toolboxes, bed boards, desk boards, chairs, and automotive parts, among others. This extensive range demonstrates the machine's adaptability to different market needs.

Moreover, the MP blow molding machine supports processing multiple plastic materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamide (PA), polycarbonate (PC), polystyrene (PS), and ethylene-vinyl acetate (EVA). It ensures a flawless production process, delivering high-quality results across various applications.

Features:

The extruding device is equipped with a variable frequency motor, which meets the requirements for screw rotation changes during the blowing process. It utilizes a screw with a large slenderness ratio, enabling the processing of various materials. This design provides strong plasticizing capabilities, high productivity, and low energy consumption. Additionally, the barrel is heated by a computer-controlled resistance heater, ensuring rapid, stable, and uniform heating.

By installing different heads in the combined extrusion system located between two extrusion machines, it is possible to produce blown products featuring visible strip lines or double layers. This versatility enhances the range of products that can be manufactured using the equipment.

The mould clamping device employs a toggle mechanism and a linear guide system. Featuring a double station design, the mould platen moves at a faster and more stable speed, improving operational efficiency and precision.

The hydraulic oil circuit has been optimized with an improved design that saves power while ensuring rapid and stable performance. Installation and maintenance of the hydraulic components are made convenient by the inclusion of a removable and mobile oil tank.

The entire machine is managed by a computer control system, and the hydraulic system utilizes double proportional control for enhanced responsiveness. It includes features such as automatic fault alarms, reliable operation, high automation levels, and memory storage for data related to 40 different mould sets.

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

Safety is prioritized with the inclusion of safety doors that integrate electrical and mechanical safety devices. These prevent the mould from closing when the safety door is open, ensuring a secure and reliable working environment.

This machine supports two types of blowing functions: straight cutting and oblique cutting, allowing for versatile processing options.

Furthermore, an oblique blowing function is available, expanding the operational capabilities of the machine.

Technical Parameters:

The extrusion system consists of multiple screw sizes, each with specific properties and performance data. Below are detailed parameters for each screw configuration:

Additionally, the extrusion head has its own heating system consisting of 14 zones and consumes 30 kW of power.

Applications:

Extrusion blow molding machines are extensively used in the packaging industry to manufacture a wide range of hollow plastic containers. These include bottles and containers for personal care and cosmetics products, such as shampoo bottles, shower gel containers, liquid soap bottles, and various cosmetic jars.

In the chemical sector, these machines produce containers like lubricant bottles, pesticide containers, and chemical reagent bottles, ensuring safe and effective packaging. The food and beverage industry relies on them for items such as milk bottles, juice bottles, and edible oil containers, predominantly made from High-Density Polyethylene (HDPE).

Pharmaceutical packaging is another vital area where extrusion blow molding is applied, producing medicine bottles and disinfectant bottles for non-sterile products.

Large hollow containers such as chemical drums and plastic barrels, ranging from 5 to 200 liters, are commonly made using extrusion blow molding machines. These containers serve various industrial and logistical purposes.

In the automotive industry, this technology is used to create essential components including fuel tanks, air ducts, coolant tanks, and fluid reservoirs. Furthermore, it produces equipment housings, which are hollow cases and enclosures for protecting various mechanical and electronic devices.

Extrusion blow molding machines also contribute significantly to agriculture by manufacturing pesticide sprayers, fertilizer containers, water cans, and other irrigation-related hollow components. These products are designed to be durable and practical for everyday agricultural use.

In the consumer market, a variety of plastic household items are produced with this technology. This includes hollow plastic toys such as balls, trash bins, storage containers, as well as water tanks and small reservoirs, emphasizing versatility in usage.

Specialized extrusion blow molding products include multi-layer co-extruded items like barrier bottles that offer anti-permeation and oxygen barrier features to protect sensitive contents. Additionally, the process supports the production of recycled plastic products, particularly non-food-grade containers made from recycled materials.

Moreover, specialized materials such as anti-static, chemical-resistant, and flame-retardant plastics are also processed using extrusion blow molding to meet unique industrial requirements.

The extrusion blow molding process typically works with a range of plastic materials. The most commonly used is High-Density Polyethylene (HDPE). Other materials include Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), Polypropylene (PP), and Polyvinyl Chloride (PVC), the latter of which is restricted in some regions.

For specialized applications, materials such as Ethylene Vinyl Acetate (EVA) and Polyamide (PA, Nylon) are also utilized.

Extrusion blow molding machines are indispensable in the manufacturing of hollow plastic products. They play a crucial role across various industries including packaging, chemical, automotive, agricultural, and consumer goods, enabling the production of durable, versatile, and functional plastic containers and components.
