The production process of products are mainly divided into the following 4 steps

1.smelting 2. casting 3. heat treatment 4. machine processing

*Before smelting, We will conduct a spectroscopic analysis of raw materials to ensure their quality.

During smelting, we mainly control the temperature and time of melting. Time and temperature are set by machines and equipment. Meanwhile, We are equipped with a timing device and handheld thermometer to check actual parameters.

*Before casting, We will analyze the aluminum liquid before the production.

During casting, the main parameters are temperature, time and pressure. Temperature, time and pressure will be set up on the machine and then cast. At the same time, We will record the time, temperature and pressure of each product and mark it for tracking.

FAI of the casting: We will use X-ray for flaw detection, analyze the interior structure before production. During production, the product will be inspected randomly to verify quality consistency.

*We mainly control the temperature and time which are controlled by computers and monitored by a recorder for process parameters check.

After heat treatment, We will test the mechanical properties on the test specimens to check if they can meet the standard requirements.

*Before machining, our technician will prepare the working instruction and production process.

FAI will be done on the first machined part before serial production. After that, the operators will conduct self-inspection and random inspection will be done by the quality department during production.

The inspection instruments will be maintained and calibrated periodically.

The inspector will conduct the FAI, routine inspection and delivery inspection of the machined products.
