How the four indicators of the mold to directly determine your mold price?

 

Mold is also a commodity, the objective conditions of the common requirements of the mold, that is, mold technical and economic indicators - summed up can be summarized as mold precision and stiffness, mold production cycle, mold production costs, and mold life four aspects The In the mold production process in all aspects, should be based on the production conditions of the four aspects of the mold to give attention to the requirements. At the same time, mold technical and economic indicators is also a measure of a country, region and enterprise mold production technology level important symbol.

  Mold precision and stiffness

  ① the accuracy of the mold

  The accuracy of the mold includes dimensional accuracy, shape accuracy, position accuracy, and surface roughness. The accuracy of the mold is mainly reflected in the accuracy of mold parts and with the accuracy.

The precision of the working part of the mold is higher than that of the product parts. For example, the precision of the punching edge is higher than that of the product parts. The numerical size and uniformity of the punching and punching gap are also the main precision One of the parameters. Usually, measured accuracy is non-working state of the accuracy (such as blanking gap), that is, static accuracy. And in the working state, by the working conditions of the impact of static accuracy and changes, into dynamic accuracy, dynamic accuracy is really meaningful data.

  The accuracy of the mold should be coordinated with the accuracy of the product, but also by the mold processing technology constraints, with the development of manufacturing technology, mold processing technology to improve the accuracy of the mold will be a corresponding increase in mold work parts of each other Conversion production will also be a reality.

  ② mold stiffness

  For high-speed stamping die, large-scale stamping die, precision plastic mold and large plastic mold is very important, not only requires its high precision, but also requires a good stiffness. This kind of mold work load is large, when there is a large elastic deformation, not only to affect the dynamic accuracy of the mold, but also related to the mold can work properly, so in the mold design, to meet the strength requirements at the same time, To ensure the stiffness of the mold, at the same time in the manufacture should also be due to improper processing caused by additional deformation.

  Mold production cycle

  The mold production cycle refers to the time from the beginning of the order to accept the mold to the mold after the test mold to pass the time to pass the mold, the current use of mold manufacturers require mold production cycle is shorter and shorter, so the length of the mold production cycle is measured mold Enterprise production capacity and technical level of one of the integrated signs, but also related to the mold enterprises in the fierce competition in the market whether the foothold. At the same time, the length of the mold production cycle is also a measure of the level of a country's mold technology management level.

  The main factors that affect the mold production cycle are: ① mold technology and the standardization of production; ② mold the degree of specialization; ③ mold production technology means advanced; ④ mold production management level.

  Mold production costs

  The production cost of the mold refers to the sum of the costs paid by the enterprise for the production and sale of the mold. The production costs of the mold include the cost of raw materials, purchased parts, outsourcing fee, depreciation of equipment, operating expenses, etc .; from the nature is divided into production costs, non-production costs and production costs, usually about the mold production costs Refers to the mold production process has a direct relationship between the production costs.

The main factors that affect the cost of mold production are: ① the complexity of mold structure and the level of mold function; ② the accuracy of mold; ③ mold material selection; ④ mold processing equipment; ⑤ mold standardization and production of specialized degree The

  Mold life

  The life of the mold refers to the total number of parts that can be machined under the premise of ensuring the quality of the parts of the product, including the sum of the number of parts processed before and after the replacement of the work surface and the wearing parts. Generally in the mold design stage should be clear that the mold applicable to the production batch type or mold production parts of the total number of mold design life. Different types of molds are not the same as the normal damage in the form, but in general, the damage to the surface of the form of friction damage, plastic deformation, cracking, fatigue damage, bite and so on.

  The main factors affecting the life of the mold are as follows:

  ① mold structure - a reasonable mold structure to help improve the carrying capacity of the mold to reduce the mechanical load to withstand the mold;

  ② mold material - should be based on the size of the production parts of the product selection;

  ③ mold processing quality - mold parts in the mechanical processing, EDM, hardened and surface treatment of the defects, will die wear resistance, anti-bite ability to produce a significant impact on the fracture capacity;

  ④ mold working state - mold work, the accuracy of the equipment used and stiffness, lubrication conditions, the pretreatment of processed materials, mold preheating and cooling conditions have an impact on the life of the mold;

  Mold technical and economic indicators between the four aspects of mutual influence and constraints. In the actual production process, according to the product parts and objective needs of the comprehensive balance of these factors, to seize the main contradictions, to obtain the best economic benefits to meet the needs of production
