custom overmolding

increase reliability with customized injection molding services from MRO

MRO manufactures custom overmolded cable assemblies that deliver reliable and durable solutions for complex interconnect problems in challenging environments, made to withstand the forces of nature. 


Our cables are built extremely tough to resist crushing, shearing, cold weather, salt spray, petro chemicals, mud and grime, severe shocks, abrasion, tension, vibrations, extreme heat, water exposure, sun exposure and
continual flexing without breaking down.

With thousands in our tooling library and many manufacturing materials, our capabilities are unsurpassed. Offering these types of value added services and customizations is just one of the reasons why MRO is unique from other manufacturing companies offering electronic solutions.

We have various in-house CNC machines, including Haas and Hurco, as well as injection mold machines such as multiple Yuhdak, Moldman, and Morgan-Press. Because of this, we are able to offer our clients complete custom and cost effective options to ensure dependable connections in the field.

MRO overmolding
working together for a solution

Our collaborative approach ensures that your custom overmolded cable assemblies are exactly what you need, with quality that will stand the test of time. 

We work directly with each client, selecting the right connectors and cable, designing the mold tooling and problem solving for unique solutions to challenging applications.

MRO custom overmolding

-we are IP68 rated and capable of operating in -40C to +85C

-we offer oil and chemical resistant options that are extremely tough and flexible

-our products withstand shock, vibration, direct impact and continual flexing, without damage to the termination point

-we offer branded or identifier custom options by using CNC precision tooling that allows for the inclusion of an embossed or pad printed personalization on the overmold itself

our overmolding colour options

MRO offers an array of in-stock colour options for overmolding.

Red, Blue, Yellow, Purple, Dark Green, Light Green, Grey, Orange,
Black, White, Tan, and Brown are all in-stock options.

In addition to colour selection, we can personalize your overmolding with brand logos, or identifiers specific per project.

We also do custom colour options, with minumum order quantities respected.

Oil Gas overmolded cable

We have worked extensively with Oil and Gas clients to provide overmolded cable assemblies and custom antenna solutions that are rugged and able to withstand hazardous Class 1 Div 2 environments.  Our in-house overmolding team has worked with many clients to produce hundreds of thousands of custom molds to increase durability and solve the unique problems found throughout land and sea rigs.  Our machine shop team can make molds from start to finish, exactly to your needs, in a matter of days.  We also have an extensive selection of durable jacket options including polyurethane, thermoplastic elastomer, thermoplastic rubber, teflon and many more.  Our cables are built to withstand abrasion, extreme heat, water ingress, blunt force impact, extreme cold, continuous flex, vibration, extreme pull force, EMI, rough handling, chemicals, oil, pests, and more.

We have extensive experience providing overmolded connectivity solutions for land-based oilfield drilling, well sites, production platforms, offshore drilling, pump rooms, pump jacks, logging systems, data vans, measurement-while-drilling, seismic systems, data acquisition and telemetry, oilfield service, Rig Communications and more.

Robotics cable assembly main

Robotics cable assemblies are at risk of failure due to twisting and turning over the course of hundreds of thousands of cycles, as well as the wear that comes from operating in industrial environments. To reduce downtime, industrial robotics cable assemblies need to be able to withstand high torsion and harsh operating conditions. At MRO, we manufacture custom robotics cable assemblies with continuous flex cable and special strain relief overmolded connections that resists wear and tear—reducing downtime and saving you money.
