In order to control the cost of mould, we must analyze the factors that affect the cost of mould.
Rational design of products
Mold enterprises often encounter such situations. In some projects, the mold has just completed the design and module, but only the change notice of the order customer comes. If it is a small change, it does not affect the mold structure, which does not matter. Sometimes the situation is severe, because changing the shape of the product, increasing the organization of the mold, or even the order of the module again. The cost has increased significantly.
3、 Whether the mold design is perfect
There are two cases that need to be analyzed.
1. Rationality and machinability of mold design
General mold enterprises must be in the old design team, experienced designers and young engineers just coming out of school. We can't ask a young engineer enterprise to independently design a high-level mold. Mold is an experienced engineer. If the mold structure is made, it can't be perfect, and some details will be rash. One of the most important and effective methods is group review.
I remember buying a German mold book in the 1970s, which has 80 boxes of advanced mold structure. The process of making mould mentioned in the book has the greatest influence on me. This process must go through multiple collective reviews of mould structure. This has the biggest impact on my mold career and really benefited a lot. Now I believe there is a consensus on this issue. Now there are many simulation methods, such as mold flow analysis, dynamic analysis of mold structure, three-dimensional comparative analysis of experimental products and designed products, which can minimize the cost of unreasonable mold design.
2. Design waste
As long as the mold users produce 500 samples, they are obviously used to develop the market. But if we design the mold 300000 times according to the service life, the cost is large, which belongs to the waste of design.
4、 Try to reduce the number of mold tests
A lot of mold processing costs of mold enterprises are calculated by the number of days. After the mold receives the order, the mold leaves the factory one day after the mold leaves the factory is qualified. If the mold still cannot be delivered for use after repeated attempts, in addition to the penalty according to the contract, the number of days the mold is in the factory and the service charge is more. Of course, the cost of mold testing is also very considerable, so the mold testing times or can not be controlled is a big blind area of mold cost control.
5. purchase of mold materials and standard parts
Select stable and reputable suppliers. If because covet cheap, and carelessly purchase, make mould problem, that is very regrettable. This is actually a lot. Although the supplier's responsibility can be investigated, the biggest loss is the mold enterprise and the mold user.
Sixth, qualified products
To sum up, in order to effectively control the cost of the mold, we must: reasonable product design, as little as possible design changes, improve the mold design and processing technology, good communication between the product engineer and the mold engineer.
