What factors will affect the processing accuracy of injection molds?


Author: MULAN -Plastic Molding Manufacturer

How to improve the processing accuracy of injection molds? Then we need to know which problems will affect the processing and production accuracy of injection molds. The following plastic mold factory Xingye Xiaobian will introduce the factors that affect the processing accuracy of injection molds: 1. Dimensional accuracy refers to the actual working size and tolerance range of the processed parts. Dimensional accuracy is controlled by dimensional tolerances.

Dimensional tolerances are the allowable variations in part dimensions during cutting. In the case of the same basic size, the smaller the dimensional tolerance, the higher the dimensional accuracy. 2. Shape accuracy refers to the actual problem of processing the surface of product parts.

The degree of overlap between the geometric shape and the ideal is the geometric shape. There are linearity, flatness, circularity, cylindricity flatness, circularity, cylindricity and line profile. The accuracy of different shapes is controlled by shape tolerance management.

In addition to roundness and cylindricity, tolerances for all these shapes are grouped into 12 classes of accuracy requirements. Level 1 is high and level 12 is low. 3. Position accuracy refers to the research surface difference between the processed parts and the actual working position and accuracy of the enterprise.

The accuracy evaluation of position information includes parallelism, perpendicularity, inclination, coaxiality, symmetry, position, circular runout and full runout. The position positioning accuracy is controlled by the position tolerance, and the position tolerance for various purposes is divided into 12 accuracy rating levels. When designing mechanical parts and machining accuracy, attention should be paid to the shape error in the position tolerance of the internal control system, and the position error should be smaller than the size tolerance.

The above are some contents that will affect the processing accuracy of injection molds. For more information about injection molds, please visit Xingye official website: http://www.dgxingyesj.com.
