Services

Three ways to work with us

Robots in development change every week, so the service is built for that. Start where your project is: each service stands on its own, and any of them can lead into the next.

Service 01

Build-to-print prototyping

“I have a drawing. I need it built, and I need it next week.”

You bringA drawing, a pinout, a BOM or a clear spec. Quantity one is fine.
You getSamples built and tested to the agreed scope. Simple assemblies in about a week, and no commitment to a later run.
Start with a drawing
Service 02

ODM, custom design and manufacturing

“I know what the joint has to do. I need help designing the cable.”

You bringFunctional requirements, the connectors at each end, the space inside the arm or chassis, or an early concept. No production drawing needed.
You getA manufacturable cable or harness design developed with our engineering partners: wire, screen, connectors, routing and bend radius. Prototyped, refined and built under your brand.
Start from a requirement
Service 03

Prototype-to-mass production

“I need a partner from rev A through volume.”

You bringA prototype to validate, or a released design you want produced.
You getA first article approved by you, then pilot and volume runs to the approved revision at our manufacturing partners in Shenzhen or Thailand, with every change carried forward. Repeat orders go straight to production.

Applications

Made for machines that move all day

Each application has its own failure mode: torsion in a wrist, drag-chain flexing on a gantry, vibration on a moving chassis. We pick the construction for yours.

Industrial 6-axis robots

Dress packs, joint cables and controller harnesses that take wrist torsion and millions of cycles on the lower axes.

Torsion ±180°/m · PUR · UL AWMHow we build for it

Collaborative robots

Slim hybrid cables through hollow joints, with power, brake and encoder in one small-diameter construction.

Hybrid · slim OD · low-friction jacketHow we build for it

AGV and AMR

Battery, drive, lidar and safety harnesses for a chassis that vibrates all shift, with locking connectors and strain relief.

Humanoid robots

High-density harnesses for 30 or more actuators, where every gram and every millimetre of routing counts.

Micro-coax · 0.08 mm² pairs · lightweight jacketsHow we build for it

SCARA and Delta

High-cycle flex cables for pick-and-place, rated for continuous acceleration in drag chains and swing arms.

How it works

What happens after you hit send

Your customer team is in the US and answers around the clock. Engineering review and production happen with our manufacturing partners in Asia. Together that makes a 24-hour clock that works in your favour.

Support

US-based customer support, 24 hours a day

Robotics teams prototype constantly. Quantity one, a new revision every week and a request that is a bit unusual are the normal case here, not the exception. So support runs as a 24-hour service: a US-based customer team for your RFQs, questions and order updates at any hour, with our manufacturing partners' engineers and factories in Asia working the other half of the clock.

Every RFQ is acknowledged the same day, reviewed with our partner's engineers overnight, and answered the next morning with a quote or a firm date. You never explain your project twice.
