Frequently Asked Questions
What materials are used for the aluminum die casting process?
The process utilizes AlSi10MnMg/DX17 material, which is processed using an 800T aluminum die-casting machine.
How is the air tightness of the product tested?
We use Airtight Tooling and Airtightness Test Equipment. The test pressure is maintained between 20kpa and 30kpa, with a stabilized pressure of 10 seconds, a test time of 10 seconds, and leakage strictly controlled within 0.3kpa.
What are the requirements for powder spraying?
The color must match the sample and be uniform. The powder thickness must be uniform with no accumulation of tumors and no exposed bottom.
How are the products packaged for transportation?
The products are placed inside knife cards and packed using dividers, containers, bubble wrap, and desiccant to prevent any damage, scratches, or deformation.
What checks are performed during final quality control (FQC & OQC)?
Final inspections verify dimensions, appearance, and outer packaging using calipers, projectors, pin gauges, and tooth gauges. All testing is conducted with calibrated equipment meeting customer and SIP requirements.
