How Does it Work?

Injection Molding

Injection molding is a process in which hot, molten material is pushed or injected into a steel die or mold which contains an internal cavity of your part shape. This process has been perfected over the past 60 years with plastics and is now being utilized in various industries including metals and advanced ceramics.

Ceramic Injection Molding

Ceramic injection molding is very similar to that of plastics as far as the molding process itself. Machines designed to heat and inject the molten material into a steel mold are easily found. However, that is where the similarities end. In order to inject a ceramic part the ceramic powder must be suspended in a medium that will flow when heated. Once the shape is created the part must be fired or sintered at high temperatures before the part will possess the properties unique to advanced ceramics.

The diagram below illustrates the basic steps to the process of ceramic injection molding.
