The following issues need to be paid attention to when making molds.
1. Don't just focus on product design and ignore mold manufacturing.
When some users develop products or trial production of new products, they often only focus on product research and development at the initial stage, neglecting the communication with the mold making unit. After the product design plan is initially determined, there are three benefits to contact with the mold manufacturer in advance.
I.It can ensure that the designed product has a good forming process, and the finalized design will not be modified due to the difficult processing of the parts.
II.The mold maker can make design preparations in advance to prevent ill-consideration in a hurry and affect the construction period.
III.To make high-quality molds, only the close cooperation between the supplier and the client can ultimately reduce the cost and shorten the cycle.
2.Don't just look at the price, but consider the quality, cycle, and service all-round.
I. 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.
II. 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 for design and analysis.
III. Some parts have special requirements during molding, and the mold also needs advanced technology such as hot runner, gas-assisted molding, and nitrogen cylinder.
IV. 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, etc.
V. Generally, large-scale 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, the number of punches, feeding devices, machine tools and mold protection devices must also be considered.
VI. The manufacturing methods and processes of the above-mentioned molds are not possessed and mastered by every enterprise. When choosing a cooperating manufacturer, you must understand its processing capabilities, not only on the hardware and equipment, but also on the management level, processing experience, and technical strength.
VII. 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, like you, must make reasonable profits in their business. 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.
3.Avoid multi-head collaboration, try to make mold making and product processing one-stop.
I. With qualified molds (test pieces are qualified), it may not be possible to produce batches of qualified products. 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.
II. Not only having a good mold, but also a good forming process. It is best to have a one-stop cooperation, try to avoid multi-head cooperation.
