To make molds, fitter is the foundation. As a fitter, you must be able to read assembly drawings, understand the functions and assembly relationships between the various parts of the mold, know which part should be processed first and which part should be processed later, which process should be done first and which process should be done last. You must also know The matching relationship between them, and the processing methods of various parts. In other words, you have to have the overall situation in mind. In many units, fitters have to do the turning, clamping, milling, planing and grinding by themselves. In the end, whether the mold is completed and whether it can be used depends on the mold fitter. As for other types of work, since the mold has been decomposed, each process only focuses on its own process. Regarding the parts processed by oneself and its role in the entire mold, one generally only knows the part that one does, and is not clear about other parts. Generally speaking, a fitter is like a commander and a scheduler. He not only has to do the work himself, but also directs others to do the work, playing the role of a commander. Mold fitters worry the most and have the strongest sense of responsibility in the entire mold processing. From the beginning of processing to the final mold test and the final product, it all depends on the mold fitter. If there is a problem with the mold trial, we need to find out the problem and find a way to solve it until the mold trial is successful. In addition, the actual experience of a mold fitter is very important. This takes time to accumulate. With the enrichment of work experience, you will be able to process various molds with ease.
