In the final analysis, a mold is also a product, so what are the factors that affect the price of a mold? In fact, it can be summarized into four aspects: the precision and stiffness of the mold, the time period for producing the mold, the direct production cost of the mold, and the service life of the mold. In each link of the production mold, attention should be paid to the four requirements of the mold according to the production conditions.
First, the accuracy of the mold
The accuracy of the mold includes the accuracy of the size, the accuracy of the shape, the accuracy of the position and the roughness of the surface of the mold. The most critical aspect of the accuracy of the mold is the accuracy of the parts and the accuracy of the fit.
The precision of the working part of the mold is higher than that of the product. For example, the precision of the blanking edge size is higher than that of the product. The numerical size and uniformity of the blanking gap between the punch and the die are also the precision. main reference data. The usually measured accuracy is basically the accuracy in the non-working state (such as blanking gap), that is, the static accuracy. When working, due to the influence of working conditions, the static accuracy changes to the dynamic accuracy, so the dynamic accuracy can be said to be truly meaningful data.
Usually the accuracy of the mold should be consistent with the accuracy of the product, and at the same time, it is affected by the mold processing technology. With the development of production technology and the improvement of processing mold technology, the precision of the mold has also been improved to a certain extent, and the interchangeable production of mold working parts will also become a reality.
2. The stiffness of the mold
This is very important for high-speed stamping molds, large stamping molds, precision plastic molds, and large plastic molds, which not only require high precision, but also require good rigidity. This kind of mold has a large workload. When the elastic deformation is large, it will not only affect the dynamic accuracy of the mold, but also affect whether the mold can work normally. Therefore, in the mold design, the rigidity of the mold should be ensured on the basis of meeting the strength requirements, and additional deformation due to improper processing should be prevented during the manufacturing process.
3. Mold production time cycle
The time period of mold production refers to the time from ordering the mold to the delivery after the mold test is qualified. At present, mold users require the production cycle of the mold to become shorter and shorter, so the length of the mold production time is to judge the production technology of a mold enterprise. And one of the comprehensive elements of management level will also affect whether the mold enterprise has a better development in the market competition. At the same time, the length of the mold production time period is also one of the factors to judge the technical management level of a mold production enterprise.
4. The service life of the mold
The service life of the mold is also a major factor affecting its price. The longer the service life, the higher the price will naturally be.
