Determinants and measurement standards of plastic mold processing quality

2019-11-19

The processing quality of plastic molds includes the two aspects of processing accuracy and surface quality. Processing accuracy is the degree of conformity of the actual dimensions, shape, and orientation of the appearance of the part after machining with the ideal geometric parameters required by the drawing; It is a few parameters to measure the appearance of plastic mold processing.

Generally, the processing accuracy of plastic molds is measured by tolerance grades. The smaller the grade value, the higher the precision; and the processing error is represented by a numerical value. The larger the value, the greater the error. High processing accuracy means small processing errors and vice versa. It must be known that the actual parameters obtained by any machining method will not be necessarily accurate. From the perspective of the function of the part, as long as the machining error is within the official service range required by the part drawing, it is believed that the machining accuracy is guaranteed.

The appearance quality of plastic molds depends on the machining quality of the parts and the assembly quality of the machine. The machining quality of the parts is also composed of the two parts of the machining accuracy and the appearance quality. The main factor affecting the machining accuracy is the scale accuracy.

There is also the function of the processing materials used in plastic molds, which requires high hardness of steel materials; at the same time, mold processing equipment is also required to have thermal stability and high reliability. For complex cavities and multifunctional composite molds, as the shape of the part becomes more complicated, the design and production level of the mold must be improved.

Especially when multiple grooves and multiple materials are formed in a set of molds or assembled into a multifunctional composite plastic mold of a component, a large number of processing programming programs are required, which have high deep hole cavity induction cutting ability and high stability, which improves Processing difficulty.

The above-mentioned determinants and measurement standards for the quality of plastic mold processing are introduced here. I hope it is helpful to everyone. If you have any other questions, please contact us.
