The Difference between Extruder and Injection Molding Machine and The Use of Them

        Extruders, screw extruders, rely on the pressure and shear force generated by screw rotation,can make the material can be fully plasticized and evenly mixed, through the die forming.

        The difference between extruder and injection molding machine and the use of extruder:At first, the extruder is the screw extruder, which depends on the pressure and shear force generated by the screw rotation, can make the material can be fully plasticized and evenly mixed, through the mouth die forming.

Use of extruder:

        1. Pipe extrusion: suitable for PP-R pipe, PE gas pipe, PEX crosslinking pipe, aluminum-plastic     composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe and various co-extrusion composite  pipe.

        2. Sheet material extrusion: suitable for PVC, PET, PS, PP, PC and other profiles and sheet extrusion. Other kinds of plastic extrusion such as wire, rod, etc.

        3. profile extrusion: adjust the speed of the extruder and change the structure of the extrusion screw can be used to produce PVC, polyolefin and other plastic profiles. Modified granulation: suitable for mixing, modifying and reinforcing granulation of various plastics.

        Secondly, injection molding machine is also known as injection molding machine or injection machine. It is the thermoplastic or thermosetting plastics using plastic molding mold into plastic products  of various shapes of the main molding equipment. Divided into vertical, horizontal, full electric. The injection molding machine heats the plastic, applying high pressure to the molten plastic so that it shoots out and fills the mold cavity.

        The use of injection molding machine:

        The injection molding machine has the ability to form plastic products with complex appearance,precise size or dense texture with metal inserts at a time. It is widely used in various fields such as national defense, electromechanical, automobile, transportation, building materials, packaging, agriculture,culture, education and health and People's Daily life.
