What is extrusion blow molding

What is extrusion blow molding? Extrusion blow molding is one of the ways of plastic processing.Modern blow molding technology originated in the 1930s. After years of development, it has developed into the third largest plastic processing method after injection molding and extrusion.

What is extrusion blow molding? First explain what extrusion is?Through the action between the extruder barrel and the screw, the material is heated and plasticized, pushed forward by the screw, and continuously passes through the head to make various cross-sectional products or semi-products. A processing method.

What is extrusion blow molding? Then explain what is blow molding?Also known as hollow blow molding, it is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state), and compressed air is introduced into the parison immediately after closing the mold to blow the plastic parison. It expands and sticks closely to the inner wall of the mold, and after cooling and demoulding, various hollow products are obtained.

1.Meet high hygiene standards: pure electric drives are more suitable for food, medicine, beverages and other products with strict hygiene requirements

2.Adopt famous factory pneumatic, hydraulic and electrical control components, long service life.

3.The extrusion motor adopts frequency conversion speed regulation, which can adapt to the requirements of the blow molding process for the change of screw speed.

Used in chemical, petroleum, food, lighting, tools, automobiles, motorcycles, toys and other fields, used to blow plastic barrels, chemical barrels, auto parts (water tank, fuel tank, air conditioning outlet duct, car tail), toys (wheels) , hollow motorcycles, basketball hoops, children’s castles), tool bags, dust collector pipes, stadiums and bus seats, etc.
