Precision plastic mold processing mainly consists of a combination of a die substrate, a die assembly and a die combination. A die with a variable cavity composed of a clamping plate, and a convex die with a variable core composed of a punch combined substrate, a punch component, a punch combined clamping plate, a cavity cut-off component and a side cut combined plate. Coordinated change of mold convex, concave mold and auxiliary molding system. It can process a series of plastic parts of different shapes and sizes.
Although the mold design is performed under the expected process conditions when the molding materials and molding equipment are selected, people's understanding is often incomplete, so it is necessary to conduct a mold test after the mold processing is completed to see the molded parts. How about the quality. It is always found later that the error correction is performed.
There are many types of bad phenomena in plastic parts, and the reasons are very complicated. There are reasons for molds and reasons for process conditions. The two often intersect only. Before mold repair, we should carry out a detailed analysis and research based on the actual situation of the undesirable phenomenon of the plastic parts, and find out the cause of the defects of the plastic parts and propose a remedial method. Because the molding conditions are easy to change, the general approach is to change the molding conditions first. When changing the molding conditions does not solve the problem, consider repairing the mold.
