These are the liquid plastics that are usually used by injection molds to produce the plastics that they will then sell. The polystyrene material is lower in cost and in material grade. ABS is a plastic that is hardier than the previous one but not flexible. Nylon can resist mot chemical and is more flexible the previous two. Polypropylene is the plastic usually used to manufacture containers because they are tough and flexible. Plastic Injection molding is also utilized for metal works.
A Plastic injection mold maker will have to make more molds if the molds are used for metal molding. Metal molding wears out the molds more than plastic molding because the melting temperature of metals is higher than plastics. Despite this additional cost, manufacturers still utilize injection molds for metal molding because the prices of metals that are molded this way are still profitable.
Uses of Plastic Injection Mold:
Plastic Injection molding is a manufacturing technique that is used for making parts from thermoplastic materials in production. After a product is designed by an industrial designer or engineer, the models are then made by a mold maker or toolmaker from metal, usually steel or aluminum.
Plastic Injection Mold is a method of molding in which the molding material is first placed in an open, heated mold cavity.
