Custom Over Molding

Over Molding? What’s that?

Using Plastic Injection machines we are able to “mold over” various electrical interconnect components such as industry common connectors, splices and even toggle switches. This provides added protection against liquids, heat and impact as well as allowing for better fit and ease of your product assembly.

Whether you are looking to weatherize an existing industry-common connector, protect a splice in your harness or simply need a full custom design, DSM&T has the knowledge and capability to deliver what you need.
