What are the common knowledge of blow molding plastic molds in Suzhou

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

Blow molding is a method of producing hollow thermosetting plastic products in Suzhou. The widely circulated injection molding targets include bottles, barrels, cans, boxes, and all containers used for packaging food, beverages, skincare products, medicines, and daily necessities. Large injection molded containers are generally used for packaging chemical raw materials, lubricants, and bulk raw materials. Other blow molded products include balls, metal corrugated tubes, and small toys. For the mechanical manufacturing industry, fuel tanks, car shock absorbers, seat backs, management center fixed brackets and their guardrails, and car headrest covers are all injection molded. For the mechanical equipment and furniture manufacturing industry, injection molded parts include casings, door frames, frames, pottery, or boxes with an open surface to the outside world.

Suzhou blow molding processing of high polymers

The general raw material for plastic blow molding in Suzhou is high-density high-pressure polyethylene, and the vast majority of milk cartons are made using this type of high polymer. Other polyolefins are also often produced and processed by injection molding. According to their main applications, butadiene polymers, polyethylene, polyester, polyurethane materials, polycarbonate, and other thermosetting plastics can also be used for injection molding.

Recently, rubber products have been widely accepted in the automotive manufacturing industry. The selection of raw materials is based on mechanical strength, aging resistance, electrical properties, electronic optical properties, and other characteristics.

Suzhou blow molding processing technology

About 3/4 of the products processed by blow molding in Suzhou are produced and manufactured by extrusion injection molding. Extrusion processing technology forces raw materials to produce goods according to a hole or grinding tool.

The extrusion injection molding process consists of 5 steps: 1. Plastic preform (extrusion of hollow plastic hoses); 2. Close the petal shaped grinding tool on the embryo, clamp the grinding tool and disconnect the embryo; 3. Inflate the cold wall of the mold core, adjust the opening, and maintain a certain working pressure during the cooling period; 4. Turn on the grinding tool and remove the blown parts; 5. Repair the burrs to obtain finished products.

Some basic knowledge of Suzhou blow molding and injection molding molds has been mentioned by Kunshan Juxinchang Company. Next time, we will introduce other professional knowledge again.
