Custom Overmolding for Wire Harnesses and Connectors
Sealed, impact-resistant connections for marine, off-road and industrial equipment — built in Conway, Arkansas
Sealed, Impact-Resistant Connections for Harsh Environments
Uniforce overmolds electrical connections to protect them where marine, off-road and industrial equipment takes the most abuse. Overmolding creates a sealed, impact-resistant part that keeps out water and moisture and stands up to vibration.
Because we also build the harness, overmolding is part of one integrated process: harness assembly, testing and molding in the same Conway, Arkansas plant. We design custom molds in-house for unique connector geometries.

Where Overmolded Harnesses Are Used
Overmolded connections hold up where water, dust and vibration would wear out a standard connector:
Marine
Dashboards, switches, lighting and engine interfaces exposed to water and spray.
ATV / UTV
Off-road equipment that sees mud, washdowns and constant vibration.
Heavy Vehicles ~ School Buses
Wiring for safety-critical systems that has to last.
Agriculture
Machinery that works in dust, moisture and high-stress conditions.
If your connections need to survive tough conditions, we can build and overmold the harness for you.
Overmolding FAQs
What is wire harness overmolding?
Overmolding forms a molded plastic layer around a wire-to-connector joint or splice. It seals the connection and adds strain relief so it lasts longer in wet, dirty or high-vibration conditions.
Why overmold instead of using heat shrink or boots?
Overmolding creates one sealed, impact-resistant piece, so there is no gap for water to get in. It also gives a cleaner look on finished OEM products.
Can you overmold harnesses you build for us?
Yes. We build, test and overmold harnesses in the same plant, with custom molds designed in-house.
What industries use your overmolded harnesses?
Marine, ATV/UTV, heavy vehicles and school buses, and agriculture.
