Analyze the reason of silver pattern of injection molded products from plastic aspect
Injection molding products are prone to silver pattern phenomenon in the production process, and this phenomenon is multifaceted. And the plastic reason is one of them:
1, moisture absorption from the atmosphere or moisture absorption from the colorant, the colorant should also be dried, it is best to install a dryer on the machine.
2, if the plastic humidity is large, the proportion of recycled material is too much or contains harmful debris (debris is easy to decompose), the plastic should be fully dried and the debris should be eliminated.
3, mixed with other plastics is also a reason
4, the amount of lubricants and stabilizers added to the plastic is too much or mixed unevenly, or the plastic itself with volatile solvents. When the heat degree of mixed plastics is difficult to take into account, decomposition will also occur.
