CHARACTERISTICS OF PE –INJECTION MOLDING MANUFACTURING IN CHINA

Plastic forming material –PE, or polyethylene, is a thermoplastic polymer that is widely used in various applications, including packaging, construction, and automotive industries. It is a lightweight, durable, and chemically resistant material that is easy to process and recycle. PE can be produced in different grades, including high-density polyethylene (HDPE) and low-density polyethylene (LDPE), which have different properties and applications. HDPE is commonly used in pipes, bottles, and containers, while LDPE is used in films, bags, and packaging materials. PE is also used in foam products, such as insulation and cushioning materials. Its main advantages are:

(1) PE material excellent electrical properties. High insulation resistance and electric strength; Over a wide frequency range, the dielectric constant and the dielectric loss tangent value of tgδ and substantially independent of frequency change. As the communication cable insulation materials are almost ideal one medium.

(2) Mechanical properties, full flexibility, and tough, resistant capacitive good.

(3) Heat aging resistance, low-temperature resistance, cold resistance, and chemical stability.

(4) Good water resistance, low moisture absorption, insulation resistance immersed in water is generally not declined.

(5) PE material as the non-polar materials, a large gas permeability. The permeability is low-density polyethylene is the most excellent in various plastics.

(6) the proportion of light, its specific gravity less than one. LDPE is particularly prominent, about 0.92g / cm3; large low-pressure polyethylene, although its density is only about 0.94g / cm3.

(7) PE material has a good processing performance, easy-to-melt plasticizing. And difficult to break down, cooling easy molding, product geometry, and structure size easy to control.

(8) with its lightweight wire and cable production, use, laying convenient, easy fitting.

PE can be processed using various plastic molding techniques, including injection molding, blow molding, and rotational molding. Injection molding is the most commonly used technique for producing high-volume parts with complex shapes. Blow molding is used to produce hollow parts such as bottles and containers. Rotational molding is used to produce large parts with complex shapes such as tanks and playground equipment.

In conclusion, PE is an excellent material for plastic molding due to its unique properties such as strength, flexibility, and resistance to chemicals and moisture. Its availability in different grades makes it suitable for various applications. The plastic molding techniques used with PE make it possible to produce parts with complex shapes and high volumes. As a result, PE is a popular choice for manufacturers in various industries.
