For high-precision molds, high-precision CNC machine tools are required for processing, and the material and forming process of the molds require strict requirements, and CAD/CAE/CAM mold technology is also required to design and analyze. However, if some parts have special requirements during molding, advanced hot runner, gas-assisted molding, nitrogen cylinder and other processes are required. Mold processing manufacturers should have CNC, wire-cut machine tools, EDM and CNC copy milling equipment, followed by high-precision grinders, high-precision three-coordinate measuring instruments, computer software and related designs. Generally, large-scale precision stamping dies (such as automobile covering parts dies) should consider whether the machine tool has an edge holding mechanism, even edge lubricant, multi-station progressive, etc. In addition to stamping tonnage, it is also necessary to consider the number of strokes, feeding devices, machine tools and mold protection devices.
The manufacturing methods and processes of the above molds are not available and mastered by every enterprise. When choosing a cooperating manufacturer, it is necessary to understand its processing capabilities, not only by its hardware equipment, but also by considering its management level, processing experience and technical strength.
For the same set of molds, the quotations obtained by different manufacturers are different. You should not pay more than the cost of the mold, nor should it be less than the cost of the mold. Ordering a set of molds with a much lower quotation would be the beginning of the trouble. Users must proceed from their own requirements and comprehensively measure.
A mold with a qualified test piece may not be able to produce a batch of qualified products. It is mainly related to the selection of the part processing machine tool, the forming process, the temperature, the time and the technical level of the operator. If you have a good mold, you must also have a good forming process. It is best to work in one-stop cooperation and avoid multi-head cooperation as much as possible. If the conditions are not met, it is necessary to choose one party to be fully responsible, and it must be clearly stated when signing the contract.
