Mould quality include the following aspects:

⑴ product quality: product size stability, consistent, finish the surface of the article, the article material utilization and so on;

⑵ life: in ensuring the quality of products, the Working cycles can be completed or the number of mold parts production;

Use ⑶ mold maintenance: whether they are the most convenient to use, easy stripping, production auxiliary time as short as possible;

⑷ maintenance costs, periodic maintenance and so on.

    The basic way to improve the quality of mold: Mold is designed to improve the quality of mold most important step to take into account many factors, including mold material selection, mold structure workability and safety, mold parts and die workability ease of maintenance, which should be considered early in the design was more comprehensive. Mold manufacturing process to ensure the quality of the mold is an important part of the mold manufacturing process precision machining and processing methods also affect the life of the mold. Accuracy of each component directly affects the overall mold assembly, the external impact of their own to get rid of precision equipment, parts need by improving processing methods to improve the technical level in the mold fitter lapping process, to improve the precision mold parts . The main parts of the mold forming surface hardening to improve the wear resistance of the surface of the mold parts, in order to better improve the quality of mold. Proper use and maintenance of the mold, the mold is also a major factor in improving quality. For example: Mold installation and commissioning should be appropriate in the case of hot runner, the power wiring to the right, the cooling water to meet the design requirements, mold in the production of injection molding machines, die casting machines, presses, the parameters to be consistent with the design requirements and many more. When used correctly mold, the need for regular maintenance of the mold, the mold guide post, guide sleeve and other parts of the relative motion should be regularly filling oil for forging dies, plastic mold, die casting mold in each of the classes should the lubricant before molding or die-forming agent is sprayed on the surface of the part.

    With the development of society, more and more attention quality of the mold, with the design and manufacture of molds degree of strengthening, implementation, quality mold mold new technology attracted more and more attention. Quality is often said that a new topic, with the improvement in the quality of mold technology improves.
