How does it happen? How did Matson metal prevent this from happening?
Foundry production is a complex multi-step process. The technical level of each process varies greatly. The skills of the operator, quality management and equipment can all affect the final quality of the sand casting or investment casting.
The key to preventing product defects in your casted products is to set clear expectations and tolerances for quality issues.
But before you can do that, you need to have a clear understanding of the different types of casting defects and their causes.
We would like to introduce the main defect type and how to avoid the problem in future.
