Common Mistakes in Die Casting Mold Making

Byxiuhui

For those familiar with the die casting industry, it is impossible to overstate the importance of the mold throughout the entire die casting process. A high-quality mold can help avoid over 70% of product defects. The root causes of the most secondary process and surface treatment defects are closely tied to the raw casting design and the mold solution.

Using plain and easy-to-understand language, we will break down common misconceptions during the mold development phase for die castings, providing a valuable reference for clients currently looking for die casting suppliers. This article series will be divided into chapters, dissecting the various pitfalls in the die casting mold making process one by one:

  1. Early Communication and Design Misconceptions: Why is DFM analysis more important than a quotation?
  2. Mold Cost Misconceptions: Focusing only on the mold unit price while ignoring the total comprehensive cost is a major mistake!
  3. Mold Forming and Post-Processing: Is a higher ejector position really more cost-effective?
  4. Casting Structure Misconceptions: Which structures, such as sharp corners, thin walls, and deep slots, will make die casting impossible to achieve?
  5. Tolerance Misconceptions: Can die castings always meet the tolerances specified on CAD drawings?

This article serves as an introduction to the series. We will subsequently write individual, in-depth technical articles addressing each of the above misconceptions, explaining the principles, case studies, and preventive solutions. Stay tuned.
