OEM & Custom Manufacturing Partnership
HISVIA facilitates OEM manufacturing partnerships between overseas companies and verified Chinese factories. We understand that IP protection, confidentiality, and quality consistency are non-negotiable for OEM relationships.

The Engineering Journey
From drawing to delivered part — every stage documented
An OEM engagement is not a transaction. It is a structured engineering process where your design moves through defined stages — each with its own quality gate before the next begins.

Drawing & Engineering
Your drawings, specifications, and quality requirements are reviewed under NDA. Our engineering team matches the right manufacturing process — CNC, casting, forging, or hybrid — before any metal is cut.

Prototype
First article produced from your drawings. Material verification, dimensional check, and functional review. You approve the prototype before any production tooling is committed.

Sampling & Approval
A small batch is produced using the committed tooling. FAI (First Article Inspection) report is generated. Your quality approval is required before bulk production begins.

Production
Bulk production runs with the agreed quality program — PPAP, in-process inspection, and traceability from raw material to finished part. Your tooling is dedicated to your orders.

Inspection & Export
Pre-shipment inspection with full documentation — dimensional reports, material certificates, COO. Export packing, documentation, and logistics handled as part of the partnership.
IP Protection
Intellectual Property Protection
We take IP protection seriously. Our OEM process includes contractual safeguards and practical measures to protect your designs, specifications, and business interests.
NDA executed before any technical information sharing
Design files and specifications shared only with contracted factory
Contractual prohibition on factory using your designs for other customers
Tooling and molds owned by you, not the factory
Option for split manufacturing across multiple factories to protect complete design
Brand-neutral packaging and documentation — your brand, not ours
Custom Manufacturing
Capabilities beyond standard catalog
Reverse Engineering
3D scanning, material analysis, and CAD modeling from existing parts. Create production-ready drawings and specifications from physical samples.
Custom Design & Engineering
Design optimization for manufacturability. Material selection consulting. Engineering support from concept to production.
Tooling & Mold Making
Custom tooling, jigs, fixtures, and molds for your specific parts. You own the tooling — we manage the production.
Custom Quality Program
PPAP, FAI, and custom inspection protocols. Your quality standards, our execution. Full traceability from raw material to finished part.
