Technical question 16, Why can't the product's 3D modeling drawing be used for product modeling?

Why can't the product's 3D modeling drawing be directly used as the product's mold file?

The 3D modeling diagram usually refers to the 3D appearance diagram of the product. As long as it is used to reflect and display the appearance of the product, there is no design about the combination of product accessories and the internal structure of the product. Generally speaking, the appearance 3D modeling diagram is solid.

The documents required for mold opening must not only show the appearance of the product, but also the internal structure diagram of the product. The more important thing is the matching diagram of product accessories made for different processes and materials.

The documents used for mold opening will take into account the point, surface, radian and wall thickness of the product according to the characteristics of the process and the characteristics of the material. At the same time, the final size obtained after processing and cooling of the product will also be considered, especially the plastic mold opening file, and the shrinkage of the plastic material during processing must also be considered.

The same is true for stainless steel molds, because the internal structure must be considered in order to develop different molds according to different processes, so that the cost can be reasonably used to produce qualified products. Therefore, in general, solid 3D files cannot be used for mold opening. The files that can be used for mold opening must be documents that fully reflect materials, processing methods, and product structures.
