After the tryout die is qualified or not, is one of the most concern, general acceptance in accordance with the following requirements.
  1.the quality of plastic parts inspection. The shapes of plastic parts should be intact, its smooth surface, not all kinds of molding defects not allowed. Dent remains the top out of the plastic parts should not be too deep, generally not more than 0.5mm. Carefully follow the pattern check plastic part dimension and surface roughness, shall comply with the requirements of drawings, and flash not excessive. The die should be able to the stable production of qualified plastic parts, therefore, to produce plastic parts can be see. 2.Performance test of mould. Mould is composed of many parts, each part coordination and work effectively, therefore, can be checked as follows. The moving mould parts is flexible and stable, motor coordination, work stable and reliable action. Action check the correct position, die can be stably, can meet the requirements of molding and productivity. The main stress parts have sufficient strength and stiffness, at work does not generate deformation. Easy demolding, plastic parts according to the predetermined requirements remain in fixed or moving die, the demoulding mechanism of action is agile. The mold has good stability, convenient adjustment, work safety, performance parts and near good. Insert the correct, reliable, convenient installation, convenient charging work, less consumption of raw material.
