Don't just look at the price, but from the full range of quality, cycle, and service.
1. There are many types of molds, which can be roughly divided into ten categories. According to different requirements such as part information, physical and chemical functions, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., select different types of mold forming.
2. Molds with high precision requirements need to be processed by high-precision CNC machine tools, and mold materials and forming processes have strict requirements, and CAD / CAE / CAM mold skills are required to plan and analyze.
3. For some parts, due to special requirements during molding, the mold also needs advanced technology such as warm runner, gas-assisted molding, and nitrogen cylinder.
4. The manufacturer should have CNC, EDM, WEDM and CNC copy milling equipment, high-precision grinder, high-precision three-coordinate measuring instrument, computer planning and related software.
5. Generally, large-scale stamping dies (such as automobile covering molds) should consider whether the machine tool has a blank holding organization, even side lubricants, and multi-station progressives. In addition to stamping tonnage, the number of punches, feeding equipment, machine tools and mold protection equipment must also be considered.
6. Not every enterprise has and grasps the manufacturing methods and processes of the above-mentioned molds. When selecting a cooperating manufacturer, we must understand its processing capabilities, not only looking at the hardware equipment, but also combining management level, processing experience, and technical strength.
7. For the same set of molds, the quotations of different manufacturers sometimes differ greatly. You should not pay more than the cost of the mold, nor should it be less than the cost of the mold. Mold manufacturers are the same as you, they must make reasonable profits in their affairs. Ordering a set of molds with a much lower quotation would be the beginning of trouble. Users must proceed from their own requirements and comprehensively measure.
