Manufacturing Process

Injection molding is a process in which a polymer is heated to a highly plastic state and forced to flow under high pressure into a mold cavity, where it solidifies. The molded part, called a molding, is then removed from the cavity. The process produces discrete components that are almost always in a net shape. The production cycle time is typically in the range of 10 to 30 seconds, although cycles of 1 minute or longer are not uncommon for large parts.
