Guangzhou Metalstar Prototype Co., Ltd. quality control

Short lead time or emergency is the normal status of prototyping tasks, but good quality is the life of a prototype factory. So, how to deliver good quality prototype parts in short lead time is the question which we keep asking to ourselves.

To achieve the goal as our company slogan -” Get it right, First time, Every time!”, as an ISO9001-certified manufacturer, Metalstar prototype implements strict quality controlling procedure for all our prototype stamping tasks, from one single part to small amount production all the same. So, we hereby share with our customers about our primary quality control procedures as following 3 steps,

1, Raw Material Purchasing & Verifying (RMPV).

    1.1, per raw material defined in customers’ design files, or use alternative raw materials agreed by customers, all raw materials must be purchased with material certificate, qualification or test report form provided by vendor.

    1.2, Metalstar verifies the raw materials again in-house or send sample pieces to 3rd party for testing and to make sure the correct raw materials to be used for prototype parts’ fabrication.

2, Fabricating Process Self-Check (FPSC) & In Process Quality Control (IPQC).

    2.1, during the tooling and prototype parts’ stamping and fabricating steps, the mold-makers check every detail of the processes or semi-finished parts by himself before releasing it to next step.

    2.2, the IPQC team members to conduct routing inspection for all the fabrication steps defined in the Quality Control Plan(QCP), this way is for discovering the defects during fabrication process, and for preventing the non-conforming parts from flowing into the next process.

3, First Article Inspection Report (FAIR). FAIR is the last checking and inspection step before sending prototype parts to customers, and it is also the most important step for ensuring that we always deliver qualified prototype parts to our customers or notify to our customers what the quality status of the prototype parts are, so that to give clear information about the prototype parts’ status before our customers to use them on next steps. In general, the FAIR content included the checking and verifying results of dimensions, technical notes, raw material and other specific requirements from customers.
