Product design change
Mold companies often encounter such a situation. In a certain project, mold has just been designed, mold frame has just been ordered back, but customer’s change notice come. If it is a small change, it will not affect the overall structure of mold. Sometimes it’s more serious, because shape of product changes, mechanism needs to be added to mold, and even mold base must be reordered. Cost has increased. So try to minimize design changes. Now there are a lot of rapid prototyping methods. Before mold is made, 3D will be used to make the whole vehicle assembly, and 3D of product can be corrected in time to minimize cost increase caused by product design change. We used to participate in the research and development of a German brand automotive. The model was going to Germany to try assembly. Plane had tossed dozens of back and forth. This cost is a material fee or a processing fee. It is really hard to say.
Is mold design perfect?
Here are two situations to analyze:
First, rationality and processability of mold design
In general mold companies, there must be old and experienced designers in design team, as well as young engineers who have just come out of school. We can’t ask young engineers to design high-level molds independently when they just come to company. Experienced mold engineers, if mold structure produced by closed doors, can not be perfect, there will definitely be some unconsidered details. One of the most important and effective methods is collective review. There are many simulation methods, such as mold flow analysis, mold structure dynamic analysis, trial products and design 3D comparison analysis, which can minimize cost increase caused by irrational mold design.
Second, design waste
If mold user require mold only produces 500 samples to develop market, but we design according to mold with a life of 300,000 times, this cost will be large, which is a waste of design.
