Customization Process

A clear and efficient workflow from concept to mass production

Step 1

Requirement Communication

Share drawings, samples, or performance specifications for initial evaluation.

Step 2

Engineering Assessment & Quotation

R&D conducts feasibility analysis, recommends optimization, and provides a detailed quote.

Step 3

Mold Design & Prototype Development

We design the mold, create fixtures, and build prototypes for verification.

Step 4

Sample Testing & Confirmation

Samples undergo full performance and dimensional testing before customer approval.

Step 5

Mass Production

With 288 machining centers, 14 die-casting machines, and complete finishing lines, we ensure stable and scalable production.

Step 6

Quality Inspection & Delivery

Each batch is inspected under unified standards, ensuring consistent quality and on-time delivery.

Quality Control

Quality is the foundation of our manufacturing process. At OKA AOQI Group, we implement a strict and standardized quality control system throughout the entire production cycle—from raw material inspection to final product delivery. Equipped with advanced testing instruments such as coordinate measuring machines (CMM), image measuring systems, spectrometers, hardness testers, and X-ray inspection equipment, we ensure precise dimensional accuracy and stable material performance. Our experienced quality team performs comprehensive inspections at every stage to guarantee that each component meets international standards and customer specifications.
