How to judge the quality of power tool die casting parts?
1. Appearance quality includes casting surface roughness, surface quality, dimensional tolerance, geometric tolerance and quality deviation.
2. Use quality refers to the performance of castings that can meet various use requirements and work, such as wear resistance, corrosion resistance, machinability, weldability, etc.
3. Intrinsic quality refers to the chemical composition, physical and mechanical properties, metallographic structure of the die casting, as well as the pores, inclusions and cracks existing in the casting.
The products made by Dongguan Jie Aosi Die Casting Factory generally have higher profits and higher requirements for appearance quality and dimensional accuracy. To make such products, Dongguan Jie Aosi Die Casting Factory must not only do well in technology, but also in Many small aspects have to be done well.
The first thing Dongguan Jie Aosi Die Casting Factory pays attention to is the material. Zinc alloy and aluminum alloy are the main die casting materials used in Dongguan Die Casting Factory. Those who have studied chemistry know that zinc and aluminum are amphoteric substances with poor chemical stability. Acid environment or alkaline environment will be corroded, even in the air, it may be corroded or oxidized, so whether it is purchasing or storage, Dongguan Jie Aosi Die Casting Factory pays special attention to the protection of materials to avoid bad, resulting in poor die casting.
