The reasons for the excessive impurities of zinc alloy die-casting part.
Nov 08, 2023
There are many reasons for the excessive impurities of zinc alloy die-casting , which mainly include the following aspects:
1. The raw materials do not meet the standards and contain impurities. These impurities may be in the process of metal melting, transportation, pouring, etc., oxides generated with air, or metal compounds generated by metal melting.
2. Recycling materials, water oral materials, flying edge and other secondary materials may bring impurities. These impurities may be produced during the recurrence and processing of raw materials.
3. Pollution in the production process, such as equipment, tools, or impurities on the hand may directly or indirectly pollute zinc die-casting.
4. The wear and falling of the mold may also cause zinc alloy casting castings to contain impurities. The material, manufacturing accuracy and life of the mold will affect the quality of the product.
5. The design of the pouring system is unreasonable or improperly used, which may lead to impurities such as oxides and sand mixed in metal solution, which will affect the quality of zinc alloy die-casting.
6. Improper operation of employees. For example, if you do not follow the prescribed operation steps, it may also affect the quality of the product.
