XACT EMS manufactures high-performance overmolded cables for defense, aerospace, industrial machinery, robotics, and harsh-weather field systems. Our low-pressure molding, high-pressure injection molding, and pour-molding capabilities produce assemblies that outperform traditional strain-relief and sealing methods — delivering maximum durability where failure is not an option.

Overmolded interconnects are the preferred solution for protecting assemblies against moisture, chemicals, impact, vibration, EMI, and repeated flexing. XACT designs overmolded solutions that exceed the performance of standard backshells and traditional cable boots — ensuring reliable operation in mission-critical systems.

What We Deliver

Low-Pressure Molding (LPM)

Soft, low-heat encapsulation ideal for PCBs, sensors, embedded electronics, and small connectors that can’t tolerate high temperatures.

High-Pressure Injection Molding

Industrial-grade sealing and mechanical strength with excellent repeatability for medium- and high-volume runs.

Pour Molding / Potting

Deep, chemical-resistant encapsulation for irregular geometries, large transitions, cable breakouts, and harsh-environment applications.

Custom Overmold Tooling

In-house tooling for strain relief geometry, wire transitions, backshell replacement, and EMI shielding integration.

Rugged Cable Construction

IP67/68 sealing, chemical resistance, multi-material molding (TPU, TPE, PA), and validation under shock, vibration, flex, and temperature cycling.
