Plastic Injection Molding: Mold products by absorbing Plasticizing, Injection, Chilling, Ejection

Employing various techniques like thermoplastic and thermoset Injection Molding, blow molding, gyratory molding, compression molding, thermoforming, structural foam molding, etc

We offer comprehensive support from initial concept to final prototyping through production and finishing so that you get the best product and value for your money. Injection molding is widely used for manufacturing a variety of parts, ranging from the smallest accessory to entire body panels for industries like automotive, aerospace and agriculture. Plastic Injection Molding mainly involves following four steps:

Plasticizing: During this process we convert the polymer material from its hard granular form to the liquid form at correct melting point. The pellets or plastic powder is melted with in the machine. Powdered or palletized materials used in Plastic Injection Molding machines mainly are, Ethylene, Polycarbonate, Nylon, Polypropylene, Acrylonitrile-Butadiene-Styrene (ABS) and Polystyrene. Injection: It is an important step during overall Plastic Injection Molding process when heated fluid is forced in to the mold at very high pressure. It is fed in to the mold through a nozzle by a long screw plunger inside a heated barrel. Chilling: It involves cooling the melted fluid to allow it go gain rigid shape. Ejection: Here, we remove the cooled and molded object from the mold cavity.

Plastic Injection Molding is widely used to manufacture automotive parts like levers, gears and switches, and medical equipment components like blood analyzer, hear pump parts, orthopedic devices, etc. Plastic Injection Molding is the reason behind a variety of plastic products we use in modern world. Be it your lawn chairs or the PC monitor you have in front of you etc. Plastic Injection is very important process in the manufacturing industry to cast and mold plastic in different shapes and sizes. Almost 32% of all plastics by weight is processed by injection molding. Through Plastic Injection Molding we pass melted plastic in to a mold cavity of inverse shape and allow it to cool resulting in the desired plastic form. We can produce geometrically complex plastic products through Plastic Injection Molding
