Common factors affecting the surface finish of
Plastic Mold steel:
1, the quality of plastic mold steel
High-quality plastic mold steel is a prerequisite for good polishing quality. Otherwise, various inclusions and pores contained in plastic mold steel are not conducive to polishing, which will affect the polishing effect.
Control measures: Use good quality plastic mold steel.
2, the workpiece surface condition
During the machining process, the surface layer of the plastic mold steel may be damaged due to heat, internal stress or other factors, and the cutting parameters may affect the polishing effect.
Preventive measures: Ensure that the surface of the workpiece is in good condition.
3, heat treatment process
If the heat treatment is not properly performed, the surface hardness of the steel or the characteristics are different, which will cause difficulty in polishing.
Prevention measures: strict control of heat treatment process.
4, polishing technology
Since polishing is mainly done by hand, if the technology is not properly used, even the highest quality steel will not achieve a high degree of mirror effect. Therefore, human skills are still the main reason that affects the quality of polishing.
Control measures: Use a person with a certain polishing technology to polish.
The above-mentioned content is the common factor that the plastic mold steel surface polishes poorly and control measures. If there is an appropriate polishing technology with high-quality tool steel and the right heat treatment process, then the surface of the plastic mold steel can certainly be polished to a satisfactory finish.
