a. Experience method:

The experience method is often a more useful way to solve problems. It uses other people's or one's own improvement on a certain problem as a reference to repair.

b. Investigation method:

The problem of some plastic injection molds must be carefully investigated through the defect of the material strip to find out the working position of the variation, and then the problem can be solved. Repairing crush is the first manifestation of this method, but some problems are actually not as obvious as crushing. If you simply rely on experience, you may not find the basis for the problem. Therefore, we must carefully investigate the variation of the material strip and the plastic injection mold, in order to truly achieve the intent of the investigation method.

c. Comparative method:

Some parts are more complicated. When the dimensions are not good, it is difficult to determine which station is the problem. This is to compare this set of plastic injection molds with the strips of other molds, or compare the current strips with Compare the strips that have been produced normally, find out their differences, and then prescribe the medicine. When the scale is not good, the comparison method is used to compare with each forming station, and the true cause of the problem will often be found quickly.

d. Measuring method:

When repairing molds, we sometimes encounter such a phenomenon. There may be several stations that can cause a certain size or deformation. After measuring each station, we find the problem. This is the measurement method. It is mainly to slowly measure each station of the material strip, so as to find the variant station. If this method is used, it can repair the multi-station blanking or the defective scale after the station is formed.
