Plastic Film Extruder Screw Barrel

Product Introduction:

After more than 100 years of development, plastic extruder has been derived from the original single screw double screw, multi-screw, even no screw and other models. Plastic extruder (main machine) can be matched with pipe, film, holding material, monofilament, flat wire, packing belt, extrusion mesh, plate (sheet) material, profile, granulation, cable coating and other plastic molding auxiliary machine, forming a variety of plastic extrusion molding production line, the production of various plastic products. Therefore, whether now or in the future, plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry. Screw is the most important component of extruder, which is directly related to the application range and productivity of extruder.

Our company is specialized in designing and manufacturing film extruder screw, made of high strength and corrosion resistance of alloy steel with high heat resistance, compression strength, strong wear resistance, corrosion resistance and other advantages, barrel and screw, implementation of plastic crushing, softening and melting and plasticizing, exhaust and compaction, and to the continuous uniform conveying rubber molding system. Generally, the length of the barrel is 15 ~ 30 times of its diameter, so that the plastic can be fully heated and fully plasticized into principle.

Product advantages:

1, Uniform film thickness

2,The stability of pressure fluctuation was increased by 30%

3,Excellent plasticizing

Scope of application:

Polyester film, nylon film, aluminized film, high barrier film, bidirectional tensile polypropylene film, low density polyethylene film, casting polypropylene film and so on are mainly used for packaging, as well as used for laminating layer. In food, medicine, chemical and other fields, food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, steamed food packaging, fast food packaging, etc. These foods are fast moving consumer goods in our life, so the demand for plastic film is also large. Used in agricultural production for plastic film, greenhouse film and various agricultural products packaging; Used in industrial production for various industrial products (machinery parts, instruments, household appliances, etc.) packaging; People used in daily life for clothing and food packaging and waterproof utensils, toys and decorations; There are a variety of materials (wood, steel, paper, etc.) surface composite film and with special functional uses of breathable film, water soluble film, insulating film, piezoelectric film and radiation film, etc., the use is very wide.
