Extrusion molding products. The production process of stretch blow molding is to control the temperature of the parison below the melting point, and use the two-way principle to improve the strength of the products. The production process is to first inject the bottomed parison, continuously transport the material to the heating furnace, heat it to the drawing temperature, then put it into the blow molding die for axial stretching with the help of the drawing rod, and then blow molding.

Extrusion molding company telephone, extrusion method is mainly used for the molding of thermoplastic plastics, and can also be used for some thermosetting plastics. The extruded products are continuous profiles, such as tubes, rods, wires, plates, films, wire and cable coatings, etc. In addition, it can also be used for plastic mixing, plasticizing granulation, coloring, blending, etc.

A method of combining two or more layers of the same or different materials into a whole by heating and pressurization with or without binder. Lamination molding is usually operated by a laminating press. A multi-layer floating hot pressing plate is installed between the moving pressing plate and the fixed pressing plate. The commonly used reinforcing materials for lamination include cotton cloth, glass cloth, paper, asbestos cloth, etc., and the resins include phenolic, epoxy, unsaturated polyester and some thermoplastic resins.
