Yes. Our in-house R&D team supports CAD files, 2D drawings and 3D models for custom wire harness projects. We also provide DFM analysis, routing optimization and prototype support to improve manufacturability and reduce production costs. All customer design files are protected, and NDA agreements are available upon request.

Yes. Our in-house manufacturing capabilities include automatic wire processing, terminal crimping, soldering, ultrasonic welding, overmolding, low-pressure molding and complete cable assembly. Keeping production under one roof helps ensure consistent quality and shorter lead times.

We source wires, cables, connectors and accessories from trusted global and local suppliers based on customer requirements. We support brands such as Alpha Wire, Belden, LEMO, Amphenol and TE Connectivity, with components sourced through authorized distributors including DigiKey and Mouser.

Every wire harness undergoes comprehensive in-house inspection before shipment. Our testing capabilities include continuity, insulation resistance, Hi-Pot, terminal pull-force, connector retention and waterproof air-leak testing. Environmental testing such as salt spray and RoHS compliance verification is also available.

Yes. We can manufacture custom wire harnesses from engineering drawings, CAD files, BOMs or physical samples. Our engineers review every project before production to ensure quality, manufacturability and cost efficiency.

Yes. We offer prototype manufacturing before mass production to verify fit, function and performance. Early prototype validation helps reduce development risks and shortens the production timeline.

We manufacture custom wire harnesses for automotive, industrial automation, robotics, medical equipment, renewable energy, telecommunications and other OEM applications. Every cable assembly is customized to meet the technical requirements of each industry.

Yes. We provide both OEM and ODM wire harness manufacturing services. From engineering support and prototype development to mass production and quality control, we deliver customized cable assembly solutions tailored to your technical and production requirements.
