Problems solved by technology

Hexavalent chromium is an ingestion poison / inhalation poison, and skin contact may cause allergies; it is more likely to cause genetic defects, inhalation may cause cancer, and has a persistent danger to the environment
The major defects of existing electroplating grade nylon materials are: 1. Need to use special nylon electroplating potion; 2. The bonding force of substrate electroplating is not high, which cannot meet the adhesion requirements of metal electroplating products; 3. The production is not flexible, High cost, the cost of traditional nylon electroplating process is about 2.4 yuan / DM, while the cost of ABS electroplating process is about 1.2 yuan / dm
Therefore, the market application is not as broad as ABS
