The raw material inspection of metal stamping parts is a key point to ensure the quality, mainly including inspections of material types, specifications, performance, etc.

Dongguan Changdong Metal Stamping Parts Company, ordered a universal tensile testing machine in 2023. Usually, Changdong metal stamping parts company will inspect the following main contents of the raw materials of metal stamping parts:

1. Material type inspection: Ensure that the materials used meet the design requirements, such as stainless steel, carbon steel, aluminum, etc.

2. Specification size inspection: Check whether the size, thickness, width, etc. of the material meet the drawings and technical requirements.

3. Surface quality inspection: Check whether there are scratches, pits, oxide scale and other defects on the surface of the material.

4. Mechanical property inspection: mainly includes hardness, tensile strength, elongation, etc., to ensure that the material has sufficient strength and toughness.

5. Chemical composition inspection: Chemical analysis of the material to ensure that its composition meets the standard requirements.

6. Non-destructive testing: such as ultrasonic flaw detection, magnetic flaw detection, etc., to check whether there are defects such as cracks and pores inside the material.

7. Material certificate: Check the material certificate provided by the supplier to confirm the source, specifications and performance of the material.

8. Environmental adaptability inspection: such as corrosion resistance, wear resistance, etc., to ensure that the material has good performance in a specific environment.

Through the above tests, the quality of raw materials for metal stamping parts can be ensured, thereby improving product quality and reliability.

For unqualified raw material, we can quickly find out it in time and return or replace it with raw material supplier, to ensure that the material used in the production meets the requirements.
