We are making foundry leak rate of car wheels stuck what I do is scrap rate is very high quality. The supervisor asked us to write a chapter on how to reduce the scrap rate of the article! Please experts explain. I have just entered the factory less than half a year. The words the better. Satisfied with my infinite points.
If the pressure casting, and filling pressure.To sum up, the main two points are: Casting Technology of parts and selection of casting processIn the case of non changing parts, mainly for the improvement of the process, and the rest is nothing!
Then, from the casting process, there are many kinds of casting, casting choice other approach, perhaps has a good effect on this. If you this is the sand casting, it requires the sand fineness (sand tightness), moisture content (permeability), runner set, casting temperature, metal components.
This is a relatively systematic problem!First of all, from the part of the casting performance, for those less important and can modify the place, improve the structure, and then can have better casting!
