Tool manufacturing unit by the manufacturing process technology to write cards and prepare for the processing and manufacturing. Parts in the mold manufacturing process to strengthen the inspection, the inspection focused on the size accuracy. After the mold assembly, mold inspection by the inspector under the test table, the main mold parts to test whether the performance of good, the only way to slang mold manufacturing quality. Although the selected molding material, molding equipment, in the desired process conditions for mold design, but awareness is often imperfect, and therefore must be in the mold is completed, the test model test, to see the parts forming how the quality. Always found after the repair to eliminate errors of the model. cell phone jammer is especially good in design.
Plastic types of adverse phenomenon mostly, because it was complex, with mold reasons, there are reasons for process conditions, the two often pay only together. In the repair mode before the emergence of plastic parts should be based on the actual situation of negative phenomena, the detailed analysis to identify causes of defects caused by plastic parts made after remedy. Easy to change because the molding conditions, so the general practice is to change the molding conditions, molding conditions when the change does not solve the problem, before considering repair of mold. Repair of mold should be cautious, not quite sure not to act rashly. The reason is that once the mold conditions change, you can not make a big renovation and restoration. Die by the test, if not in use, you should completely erase stripping waste, dust, oil, etc., coated with butter or oil or other rust rust inhibitor, related to storage sites custody. The working frequency of cell phone jammer also includes 1805~1880MHz.
The mold design to mold successful start, inspection date, during which the technical data generated by, for example, mission statement, parts diagrams, technical specifications, the mold assembly diagram, mold parts diagrams, base maps, mold design specification, test records table, mold repair mold test records, required to be systematically finishing, binding, numbering archiving.
