FAQ's

What are your lead times?

For rapid prototypes, the expected lead time is 7 days. For mass production, your order is delivered in 15 to 20 days.

Do your custom wiring harnesses meet industry standards?

Absolutely. We hold ISO 9001 and UL certifications, comply with TS 16949 and IATF 16949 standards, and adhere to REACH and RoHS EU regulations.

Do you offer non-disclosure agreements (NDAs)?

Yes. We respect your privacy, and we’re happy to provide an NDA if you’d like one.

What is your production capacity?

We can handle small orders as well as large-scale production requirements without compromising on quality. No order is too big or too small.

What’s the difference between custom wire harness assembly and cable assembly?

Wire harnesses focus on organization, bundling wires with ties, tape, or sleeves for controlled environments. Cable assemblies provide robust protection with a durable outer jacket, shielding wires from moisture, heat, and friction in demanding conditions.
