How To Improve Mold's Quality

- Jul 12, 2019-

Mold quality includes the following aspects:

(1) Product quality: the stability and conformity of the product size, the smoothness of the surface of the product, the utilization rate of the product materials, etc.;

(2) Mold life: the number of work cycles or the number of parts produced by the mold under the premise of ensuring the quality of the product;

(3) Mold  maintenance: whether it is the most convenient to use, easy to demould, and the production auxiliary time is as short as possible;

(4) Maintenance costs, maintenance periodicity, etc.

      The basic way to improve mold's quality:  mold's designing is the most important steps to improve the quality of the mold. Many factors need to be considered, including the selection of the mold material, the usability and safety of the mold structure, the machinability of the mold parts and the mold. The convenience of maintenance, these should be considered as thoughtfully at the beginning of the design. The manufacturing process of the mold is also an important part of ensuring the quality of the mold.


     The processing precision method in the mold manufacturing also affect mold's life. The accuracy of each component directly affects the overall assembly of the mold. In addition it will influent accuracy of  equipment , it is necessary to improve the machining accuracy of the mold parts by improving the machining method of the parts and improving the technical level of the fitter in the mold grinding process. Surface strengthening of the main forming parts of the mold to improve the surface wear resistance, thereby improving the quality of the mold. The correct use and maintenance of the mold is also a major factor in improving the quality of the mold.

      For example, the installation and debugging mode of the mold should be appropriate. In the case of hot runners, the power supply wiring should be correct, and the cooling water circuit should meet the design requirements. The parameters of the injection molding machine, die casting machine and press in the production of the mold should be consistent with the design requirements. and so on. When the mold is used correctly, the mold needs to be regularly maintained. The guide post, sleeve and other parts with relative movement of the mold should be filled with lubricating oil. For each of the forging mold, plastic mold and die-casting mold, A lubricant or mold release agent should be applied to the surface of the molded part before molding.


      With the development of society, the quality of molds has received more and more attention. With the enhancement of design and manufacturing molds and the realization of new mold technologies. Quality is improving as mold technology improves.
