Why ODM / OEM Teams Choose Us

Built for Product Launches

DFM Before Tooling

Free design-for-manufacturing review of your internal wiring within 24 hours — catch routing, crimp and cost issues before they reach the production line.

Automotive-Grade QC, Consumer Pricing

The same IATF 16949 system that serves our automotive clients inspects every consumer harness — a quality level most consumer cable shops can't offer.

NPI to Mass Production

Prototypes in 7–10 days, flexible pilot runs, then automated lines that scale for seasonal launch volumes without requalification.

Frequently Asked Questions

Yes. As a leading manufacturer, we operate fully automated crimping and soldering lines designed for scalability. We can ramp up production quickly to meet seasonal demands (e.g., Black Friday, Christmas) while maintaining strict quality control.

We run automated crimping for JST PH, XH and SH series, Molex PicoBlade and Micro-Fit, and equivalent micro connectors from 1.0 mm pitch. Wire gauges from 16 AWG power conductors down to 32 AWG signal wires can be combined in a single multi-branch harness.

Absolutely. All our consumer electronics wire harnesses strictly adhere to RoHS, REACH, and Sony Green Partner standards. We also offer a wide range of Halogen-Free and bio-based insulation materials for eco-conscious brands.

Yes. Our in-house tooling workshop allows us to design and fabricate custom molds for strain reliefs, logos, and unique connector shapes within 7-10 days to match your product's aesthetic requirements.
