What are the consequences of excessive surface polishing for plastic mould processing?
Plastic mold is an indispensable part of the plastics processing industry.Due to the wide variety of plastic varieties and processing methods, not only the structure of plastic molding machine and plastic products are different, but also the type and structure of plastic molds are different to some extent.
In the process of plastic mould processing, polishing is also a necessary step for it, but if it is not mastered well, it is easy to cause the problem of excessive polishing, which makes the quality of plastic mould processing cannot meet the standard.What are the adverse consequences of excessive polishing of plastic mould?
The so-called overpolishing refers to the deterioration of the surface quality of plastic mould processing due to too long polishing time, accompanied by defects such as orange peel and micro-pit.In particular, plastic mold processing mechanical polishing, such problems are more likely to arise.
We refer to the surface roughness and non-specification of plastic mould as orange peel, which is mainly caused by too much pressure, too long polishing time and improper polishing methods.When some users find that the surface quality of plastic mold processing is poor, they will often improve by increasing the polishing pressure and prolonging the polishing time, but they will often be counterproductive.
The micro pit formed on the surface of plastic mould processing is due to the non-metallic inclusions of steel, which are usually hard and brittle oxides. The result of pulling out of the steel surface in the polishing process will also reduce the quality of plastic mould processing.
