Pvc Overmolding

Plastic injection overmolding also known as injection molding, is an injection-molding molding method. There are many kinds of overmolding injection molding: silicon overmolding, insert overmolding, pvc overmolding.

The injection molding process can be roughly divided into the following 6 stages:

Mold clamping, plastic injection, pressure keeping, cooling, mold opening, and product removal.

By repeating the above process, products can be produced periodically in batches. The molding of thermosetting plastics and rubber also includes the same process, but the barrel temperature is lower than that of thermoplastics, and the injection pressure is higher.

Nowadays, the trend of processing technology is developing in the direction of high-tech. These technologies include: micro-injection, high-fill composite injection, water-assisted injection, mixed use of various special injection molding processes, foam injection, mold technology, simulation technology, etc.

Material list

The main raw materials of injection molding products are: polystyrene, polyethylene, polypropylene and ABS4 kinds of resins. These four resin injection molding plastic products account for more than 80% of the total raw materials of injection molding products. Among them, the application amount of polystyrene, polyethylene and polypropylene resin accounts for 70% of the total amount of raw materials used. In addition, raw materials for injection molding products include: polyvinyl chloride, acrylonitrile-styrene copolymer, cellulose acetate, cellulose acetate butyrate, ethylene-vinyl acetate copolymer, polyamide, polybutylene terephthalate , polyethylene terephthalate, polycarbonate, phenolic resin, polymethyl methacrylate, polyoxymethylene, polyurethane, polyphenylene ether, etc.

FAQ:

1 Q: What is Overmolding in injection molding?

Overmolding is a multi-step injection molding process where two or more components are molded over top of one another. Overmolding is sometimes referred to as two-shot molding because it is a two-step process.

2 Q: What is Overmolding used for?

Overmolding is a manufacturing process that combines two, often dissimilar materials into one part. Today, two manufacturing technologies can perform overmolding—injection molding and 3D printing.

3 Q: Can you Overmold the same material?

Yes, you can overmold the same material. This is especially useful when using thermoplastics to form the interior and exterior layers in overmolding and insert molding.

4 Q: What is Overmold in manufacturing?

Overmolding is a unique custom injection molding process that results in a seamless combination of multiple materials into a single part or product.
