How to select high-quality precision castings
Whether the quality of precision casting products is excellent or not directly affects the operating profit and reputation of the foundry, and also has a very direct impact on the customers who choose to buy precision casting products. However, there are many precision casting manufacturers on the market, and the casting products processed and produced by them are various. How can we choose high-quality precision casting products? The following methods may be used to judge the quality.
1. From the perspective of product packaging
With the increasing standardization of modern industrialization, formal precision casting manufacturers increasingly attach importance to the external packaging quality of products. When they process and produce precision casting products, they generally design the external packaging of products. The factory name, factory address, production date, use instructions, certificate of conformity and other certificates will be prepared, the packaging quality is qualified, and the identification is complete.
2. Judging by the appearance quality of castings
High-quality precision castings have smooth surface processing effect, no burr, high dimensional accuracy, and good painting quality, while poor quality castings often have defects such as rough surface, sand holes, cracks, or loose surface due to the difficulty of quality control.
3. Judge product quality through production process
In order to improve their competitiveness, regular manufacturers often use more advanced production processes to produce castings when producing and processing castings. Each casting product will go through multiple interlocking process links from design to delivery, greatly reducing the production of defects in precision castings, while small manufacturers do not have a series of process processes when processing castings.
Therefore, if you want to select high-quality precision casting parts, you can refer to the above introductions, which are very worthy of reference.
