Why is the cost of mold opening for plastic mold products so high? From ten thousand to hundreds of thousands, or even millions. This depends on the structural complexity of your product, if the product is relatively simple, the mold opening cost will be cheaper, on the contrary, the structure is more complex, and the larger product mold opening cost will be relatively high. For example, a simple building block, it only needs a set of flat molds to complete, the mold structure does not need to use a diagonal top and row position, then, this from design to tryout only need to spend about 20,000 a cost. So, what about a more complex product structure? For example, the plastic mold of the automobile structural parts, this set of molds needs to be designed with more complex components to compose, in order to be able to make the product.
A complex set of plastic molds has many structures, such as row position, oblique top, internal core extraction, front mold ejection and so on.
Let's put the product design aside, just look at the cost component of the plastic mold, is composed of three links, the first is the pre-design of the plastic mold, the second is the mold processing process (computer gong, discharge, wire cutting, milling machine, grinder, three-dimensional detection, etc.) and assembly; The last one is a tryout, and if the first sample of the test is OK, it can be put into mass production normally.
If you want to reduce the cost of plastic molds, you must first start from the source, design the product to be perfect, and take all the problems into account. Because if your product itself has a problem with the design, then, the follow-up will involve product changes, once the product needs to be changed, then the design of the mold must also be followed by the mold, after the completion of the mold, and then another round of mold trial. The time cost required for a small change in the mold is 3-5 days.
After the product design is good, you need to find a reliable plastic mold company to design the structure of the mold according to the product, a good mold company will help you save costs from the source when assessing the feasibility in the early stage, and the success rate of the rapid first sample trial is also very important, the success rate of the first sample is high, and it will also save you a lot of manpower and material costs. On the contrary, the bad plastic mold company before the mold trial, repeated repair of the mold is still not up to your size tolerance requirements, finally, it is difficult to achieve mass production, which will cause your products can not be sold in the market in a short period of time, thus missing the best market opportunity, time is money.
