What are the inspection standards for aluminum alloy die casting products？

 Requirements

1. The surface condition of the die casting, observe whether there are oil stains, dust, scratches, flow marks, burrs, etc. The surface of the casting is not allowed to appear loose, air bubbles, under-casting and other defects.

2. The surface processing specifications of the die-casting parts, whether the spraying, mechanical processing, surface treatment processing and other processes meet the specifications.

3. The burrs and flashes of the die-casting parts should be removed, and the sprue opening should be filed according to the process.

4. The ejection traces should be cleaned up.

5. There is no corrosive medium in the use range of castings.

 Inspection

1. There are many types of specific inspections for die castings. Generally, there are visual inspections, dimensional inspections, internal inspections, special inspections, etc. The internal inspections also include penetration inspections, radiological inspections, ultrasonic inspections, etc., in addition to mechanical tests and analytical tests. Special inspections include corrosion tests and quality inspections.

2. It should be noted that when formulating inspection standards, too strict quality inspections should be avoided, because defect-free die castings are impractical.
