OEM/ODM: A Process Built for Brands
Weisi offers flexible OEM/ODM cooperation — new product development, small-batch trial production, and full-scale mass production. Every project runs through the same five-step process, tracked end-to-end in our CRP digital system.
- 1
Inquiry & Requirements
Send your product idea, target spec, or reference sample. Our engineers respond within 24 hours with a feasibility assessment.
- 2
Sample Development
Structural design and sample build by the in-house R&D team — from requirements analysis to a testable prototype.
- 3
Testing & Validation
Samples validated in our 8-instrument lab: bend-life, insertion force, aging, vibration, salt spray, UV, abrasion, and real-device testing.
- 4
Mass Production
Production scheduled through the CRP system with order progress tracking — manufacturing across 10 production lines.
- 5
QC & Delivery
Finished goods tested on real devices, outgoing inspection documented, packaging transport-validated before shipment.

OEM/ODM FAQ
Can a custom cable project start with an idea rather than drawings?
Yes. In one Weisi ODM project, an Amazon seller started with ideas for three cable designs. Sales and engineering developed the requirements through 3D models, samples and tooling; all three designs had entered batch production by November 2026. Feasibility and scope are assessed for each new project.
What can be customized in an OEM/ODM project?
Appearance and structure, function, materials and process, packaging, and brand visuals. Weisi provides full technical support from requirements analysis and structural design through sample development, test validation, and mass-production introduction.
Do you support new product development from scratch?
Yes. Weisi is R&D-driven: an in-house team of 4 R&D engineers supports new product development, small-batch trial production, and full-scale mass production.
Can you build high-power and high-speed cables?
Yes. Weisi manufactures USB-C cables up to 240W, and high-speed lines including USB 3.2 Gen2 with laser-welded terminals and USB4 cables supporting 40Gbps/80Gbps custom development.
What is an E-Marker chip and do your cables include one?
An E-Marker is an identification chip required in USB-C cables rated above 60W (100W/240W) — it tells the charger and device the cable’s certified current and data capability. Weisi’s 100W/240W cable models are built with E-Marker chips as required by the USB-C specification.
