Today, the editor of Kunshan Juxinchang Company will talk about some basic knowledge of blow molding and injection molds in Suzhou.



Blow molding in Suzhou is a way of producing hollow thermosetting plastic products. Popular injection molding targets include bottles, barrels, cans, boxes, and all containers for packaging food, drinks, cosmetics, medicines and daily necessities. Large injection molded containers are generally used for packaging of chemical raw materials, lubricants and bulk raw materials. Other blow molded products include balls, metal bellows and small toys. For the machinery manufacturing industry, fuel tanks, car shock absorbers, seat backs, center fixed brackets and guardrails and headrest coverings are all injection molded. For the machinery and furniture manufacturing industries, injection molded parts include casings, door frames, frames, pottery or boxes with an open side.
Suzhou Blow Molding Processing Polymer
The raw material of general plastics in Suzhou Blow Molding Processing is high-density high-pressure polyethylene, and most milk boxes are made of this type of polymer. Other polyolefins are also often processed by injection molding. Depending on the application, butadiene polymers, polyethylene, polyester, polyurethane, polycarbonate and other thermosetting plastics can also be used for injection molding.
Recently, rubber products have been widely accepted in the automobile manufacturing industry. The selection of raw materials is based on mechanical strength, aging resistance, electrical properties, electronic and optical properties and other properties.
Suzhou blow molding processing technology
About 3/4 of the products processed in Suzhou blow molding are produced by extrusion injection molding. The extrusion process forces raw materials to follow a hole or mold to produce products.
The extrusion injection molding process consists of 5 steps: 1. Plastic parison (extrusion of hollow plastic hose); 2. Close the flap and grinding tool on the parison, clamp the grinding tool and disconnect the mold 3. Blow the mold toward the cold wall of the mold core, adjust the opening and maintain a certain working pressure during the cooling period; 4. Open the mold and remove the blown parts; 5. Trim the burrs to obtain the finished product.
Some basic knowledge about Suzhou blow molding and injection molding. The editor of Kunshan Juxinchang Company mentioned this first, and will introduce other professional knowledge next time.
