Custom Overmolding Services

Insert overmolding integrates metal or plastic inserts into molded parts, improving structural integration and reducing separate assembly steps. For example, metal inserts in a plastic housing provide secure fastening points for screws.

Multiple materials are injected sequentially via a multi-cavity mold or rotary mechanism within a single continuous cycle. This process, commonly known as two-shot molding, 2K or 3K molding, is ideal for high-efficiency production of complex parts in one streamlined workflow, such as dual-color buttons and ergonomic grips.

Co-injection molding combines two materials within a single molding cycle, resulting in a single part with different material properties in different areas. For example, a hard plastic core paired with a soft elastomer outer layer. This process is particularly well-suited for producing parts with significantly different properties on the inside and outside.

Thermoplastic elastomer (TPE) is overmolded onto a rigid substrate to create soft, flexible zones. This technology enhances product hand feel and aesthetics. Typical applications include tool grips and wearable devices, where TPE elasticity improves comfort and durability.

Combine liquid silicone rubber (LSR) with suitable substrates to create flexible components for sealing, cushioning, and other applications requiring silicone’s specific material properties. LSR overmolding is particularly well-suited for reliable applications in high-temperature and harsh environments.

Coating the exterior of wire or cable with plastic creates a durable and sealed connection, such as a stress relief feature or protective sheathing for electronic components. This is essential for long-term, reliable applications involving movement, vibration, or humid environments.
