Yizhong hardware is committed to the continuous improvement and optimization of all custom manufacturing capabilities from prototype to production, and the corresponding quality control process, including CNC machining, rapid prototyping and rapid tooling.

We strictly follow the ISO 9001 certified quality management system, based on a series of standardized production procedures and work instructions, and use advanced testing equipment to measure and inspect each production step to ensure that your project meets stringent quality specifications.

Inspection And Quality Control Procedures

Our quality process is run through the whole projects from RFQs to production shipment.

  • Two independent reviews of the purchase order is where our QA begins, determining that there are no questions or conflicts regarding dimensions, material, quantities, or delivery dates.
    Then reviewed by experienced personnel involved in the set up and production and individual inspection reports are made for each operation that is required to produce the part.
    All special quality needs and instructions are documented and inspection intervals are then assigned based on tolerances, quantities or complexity of the part.
    We minimize risk by tracking and analyzing every step of our manufacturing process to minimize part to part variation, and assure consistent, reliable quality for every part, every time.

Consistent quality control, from part to part, product to project, we pay attention to detail, problem-solving, researching new materials and processes, investing in technology, building and sustaining a team of professional rapid manufacturing.
