(1) It can ensure that the designed product has a good forming process, and the finalized design will not be modified because the parts are difficult to process.
(2) The mold maker can make design preparations in advance to prevent ill-consideration in a hurry and affect the construction period.
In short, to make high-quality molds, only the close cooperation between the supply and demand sides can ultimately reduce the cost and shorten the cycle.
2. Don't just look at the price, but consider the quality, cycle and service in all aspects
There are many types of molds, which can be roughly divided into ten categories. According to different requirements of parts material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., different types of molds are selected for forming.
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 technology needs to be designed and analyzed. Some parts have special requirements during molding, and the mold also needs to use hot runner and gas-assisted molding. Manufacturers should have CNC, EDM, wire cutting machine tools and CNC copy milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer design and related software. Generally, large-scale stamping dies (such as automobile cover molds) should consider whether the machine tool has a blank holder mechanism, or even edge lubricants, multi-function bit progression, etc. In addition to stamping tonnage, punching times, feeding devices, machine tools and mold protection devices should also be considered.
The manufacturing methods and processes of the above-mentioned molds are not possessed and mastered by every enterprise. When choosing a cooperative manufacturer, you must understand its processing capabilities, not only by hardware equipment, but also by management level, processing experience and technical strength. For the same set of molds, there is sometimes a big gap between the quotations of different manufacturers. You should not pay more than the value of the mold, nor less than the cost of the mold. Mold manufacturers, like you, want to make reasonable profits in their business. Ordering a set of molds at a much lower price can be the start of trouble. Users must start from their own requirements and comprehensively measure. A much lower die would be the start of trouble. Users must start from their own requirements and comprehensively measure.
3. Avoid multi-head collaboration and try to make one-stop mold making and product processing.
With qualified molds (qualified test pieces), batches of qualified products may not be produced. This is mainly related to the selection of the machine tool for processing the parts, the forming process (forming temperature, forming time, etc.) and the technical quality of the operator. With a good mold, there is also a good forming process, preferably one-stop cooperation, and try to avoid multi-head cooperation. If the conditions are not met, it is necessary to choose one party to be fully responsible, and it must be clearly defined when the contract is signed.
