Regulations on injection mold processing, testing, repair and maintenance of Donglai precision mold company in 2024

Injection mold processing test

After the processing of the injection mold, when selecting the molding materials, such as PC or ABS, and the injection molding machine, the mold design under the previously expected conditions is usually incomplete. Therefore, it is necessary to carry out the mold test after the processing of the injection mold to see the quality of the molded plastic parts. Find out the problem as soon as possible and carry out the mold repair to eliminate the fault.

Most of the varieties of plastic injection molding parts show adverse phenomena, and the reasons are also very messy. There are reasons for plastic mold, and there are reasons for the skills and conditions of injection molding workers. The two are usually only together. Before mold repair, detailed analysis and research should be carried out according to the actual situation of the adverse phenomenon of the plastic parts, and the causes of the defects of the plastic parts should be found out, and then the remedial measures should be put forward. Because the molding conditions are simple to change, the usual practice is to change the molding conditions first, and then consider repairing the mold when changing the molding conditions can not solve the problem.

Repair the mold should be more stable, not very grasp can not act rashly. The reason is that once the mold conditions are changed, it can not be greatly transformed and restored.

Filing of plastic mold design data, plastic mold forming parameters and other materials

After the test, if the plastic mold is not used for the time being, it should be completely wiped off the demoulding residue, dust, oil stain, etc., coated with butter or other anti rust oil or anti rust agent, and closed to the storage place for safekeeping.

From the successful processing of the planned plastic mold to the qualified inspection, the skill materials occurred during this period, such as the plastic mold assignment, part drawing, skill statement, plastic mold general assembly drawing, mold part drawing, base drawing, mold planning statement, inspection record sheet, mold trial and repair record, shall be systematically sorted out, bound, numbered and archived according to the rules. It seems like a lot of trouble, but it is very useful for repairing molds and planning new plastic molds in the future.
