Three precautions in the process of plastic mold processing

writer:LI SONG Share

Plastic mold processing refers to the processing of forming and blanking tools, in addition to shearing molds and die-cutting molds. Under normal circumstances, the mold consists of two parts, an upper mold and a lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold will be obtained or the corresponding waste will be removed.

Work pieces ranging from electronic connectors to automotive dashboards can be molded. Progressive mold refers to a set of molds that can automatically move the processed workpiece from one station to another, and get the molded part at the last station.

High-Quality Preform Mold
Shanghai Lisong Machinery will introduce you to three precautions in the process of plastic mold processing:
1: Mold cleaning thimble during plastic mold processing
The service life of the cleaning thimble of the mold is one year. If the cycle exceeds one year, the thimble will become dirty on the surface due to gas accumulation and mold impurities. It is recommended to clean up in time. After the cleaning is completed, we recommend that there is no friction between the thimble, and it is recommended to coat the surface. The upper layer of lubricating oil acts as an isolation,

2: Mold molding cycle during plastic mold processing
This cycle includes injection time and product cooling time. How to control the production time of these two modules is particularly important, and it is directly related to the quality of the product.

Three: The speed of plastic injection during plastic mold processing
Because the plastic mold is simply to inject rubber into the mold, the injection speed is particularly important. Whether the injection speed is fast or slow directly affects the shape of the product after molding.
