What are the general requirements for mold making?

(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 produce high-quality molds, only the close cooperation between the supplier and the demander can ultimately reduce costs and shorten the cycle.

2. Don't just look at the price, but from the full range of quality, cycle, and service

There are many types of molds, which can be roughly divided into ten categories. According to different requirements of parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., different types of mold forming are selected.

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 is required to design and analyze. Due to the special requirements of some parts during molding, the mold also needs to use hot runner and gas-assisted molding. The manufacturer shall have CNC, EDM, wire cutting machine tools and CNC copy milling equipment, high-precision grinders, high-precision three-coordinate measuring instruments, computer design and related software. Generally, large-scale stamping dies (such as automobile covering parts dies) should consider whether the machine tool has a blanking mechanism, even edge lubricant, and multi-functional position progression. In addition to stamping tonnage, the number of punches, feeding devices, machine tools and mold protection devices must also be considered.

The manufacturing methods and processes of the above molds are not available and mastered by every enterprise. When choosing a cooperative manufacturer, we must understand its processing capabilities, not only by the hardware equipment, but also by combining the management level, processing experience and technical strength. For the same set of Helmet Mould, 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, like you, must make reasonable profits in their business. Ordering a set of molds with a much lower price would be the beginning of the trouble. Users must proceed from their own requirements and comprehensively measure. A much lower mold can be the beginning of trouble. Users must proceed from their own requirements and comprehensively measure.

Third, avoid multi-head collaboration, try to make mold making and product processing one-stop.

With qualified molds (qualified test pieces), batches of qualified products may not be produced. This is mainly related to the selection of the part processing machine tool, 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, it is best to cooperate in one-stop, 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 clear when signing the contract.
