What are Molding Companies?

Molding companies specialize in creating customized plastic products through the molding process. The molding process involves heating and melting plastic resin and injecting it into a mold, where it cools and hardens into the desired shape. Molding companies may use different types of molding techniques, depending on the product specifications.

Types of Molding Companies:

There are several types of molding companies, each specializing in different molding techniques. Injection molding companies use high pressure to inject molten plastic into a mold, producing complex and precise shapes. Blow molding companies use air pressure to inflate a plastic tube, creating hollow objects like bottles and containers. Rotational molding companies use heat and rotation to create large, hollow objects like tanks and playground equipment. Compression molding companies use heat and pressure to compress plastic into a mold, creating solid products like automotive parts and electronic components.
