What issues should I pay attention to when making plastic mold products?

First, some users in the development of products or new products trial production, often initially focused on product development and development, neglecting communication with the mold production unit. After the initial design of the product design, that is, in advance contact with the mold manufacturer has two advantages:

(1) It can guarantee that the designed product has a good forming process, and will not modify the stereotyped design because the part is difficult to process.

(2) The mold maker can make design preparation in advance to prevent inconvenience in the haste and affect the construction period.

In short, the production of high-quality plastic mold products, only the close cooperation between the supply and demand, in order to ultimately reduce costs and shorten the cycle.

Second, don't just look at the price, we must consider all aspects 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 and economy, different types of molds are selected.

Molds with high precision requirements need to use high-precision CNC machine tools, and the mold materials and forming processes have strict requirements. CAD/CAE/CAM mold technology needs to be designed and analyzed. Some parts have special requirements due to molding. Hot runners and gas-assisted molding are also required. 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, etc. Stamping dies (such as automotive cover parts molds) should consider whether the machine tool has a crimping mechanism, even side lubricants, multi-function level advancement, etc. In addition to stamping tonnage, it is necessary to consider the punching, feeding device, machine tool and mold protection device.

The manufacturing methods and processes of the above-mentioned molds are not possessed and mastered by every enterprise. When selecting a cooperative manufacturer, we must understand its processing capabilities, not only the hardware equipment, but also the management level, processing experience and technical strength. Molds, different manufacturers sometimes have a big gap. You should not pay more than the cost of the mold, and should not be less than the cost of the mold. The mold manufacturer like you, to obtain a reasonable profit in the business. Custom one A set of molds with much lower quotations can be a hassle to start. Users must start from their own requirements and measure them comprehensively. A much lower mold will be a troublesome start. Users must start from their own requirements and measure them comprehensively.

Third, avoid multi-headed collaboration, try to make mold and product processing one-stop

With a qualified mold (test piece qualified), it is not always possible to produce a batch of qualified products. This is mainly related to the selection of the machine tool, the forming process (forming temperature, forming time, etc.) and the technical quality of the operator. With good molds, there must be good forming and processing. It is best to work together in a one-stop manner. Try to avoid long-term cooperation. If the conditions are not available, you must choose one party to be fully responsible. Be sure to write clearly when ordering the contract.
