Top 6 Plastic Injection Molding Companies in Michigan

Plastic mold making is the process of obtaining plastic products by injecting molten plastic pellets under high pressure into a mold and after it cools and solidifies forms a final plastic product. It is a process appropriate for goods with irregular shapes being manufactured in large numbers. This process was first done by John W. Hyatt, an American inventor who was trying to replace billiard balls from being made out of ivory to plastic.
