RTM

What Is RTM?

Resin Injection (also known as Resin Transfer Molding or RTM) continues to gain popularity as an effective alternative to conventional molding processes. It offers the unique advantage of delivering detailed parts that are smooth on both sides. This versatile closed-mold process also emits significantly less styrene than open-mold and spray-up processes. Resin Injection allows preloading of the mold with glass and all types of inserts, bosses and coring materials.

How Does RTM Work?

First the reinforcement is formed on a Preformer, generally built to the specific part design. Then, gelcoat is applied to the mold and the reinforcement is loaded into the mold cavity. The mold is closed and the injection process begins.

When Should You Choose RTM?

When you need speed and accuracy, particularly on complicated part shapes. RTM allows the production of several identical parts per hour from a single mold, while reducing labor and material costs (compared to open molding). There are several different methods of Resin Injection including: manual injection, RTM lite, and fully automated injection.
