Do you know the problems that need to be paid attention to when making plastic molds?

1. Don't just focus on product design and ignore plastic mold manufacturing:

After the product design plan is initially determined, there are three benefits to contact with the mold manufacturer in advance:

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 plastic mold maker can make design preparations in advance to prevent ill-consideration in a hurry and affect the construction period.

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

2. 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 of parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., choose different types of mold forming.

2. Plastic 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 must be used for design and analysis.

3. Due to the special requirements of some parts during molding, the mold also needs to use hot runner gas-assisted molding, nitrogen cylinder and other processes.

4. The manufacturer shall have CNC, EDM, WEDM and CNC copy milling equipment, high-precision grinders, high-precision three-coordinate measuring instruments, computer design and related software.

5. Generally, large-scale stamping dies (such as automobile covering parts dies) should consider whether the machine tool has a pressing 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.

6. The manufacturing methods and processes of the above-mentioned molds are not available and mastered by every enterprise. When choosing a cooperative manufacturer, it is necessary to understand its processing capabilities, not only by the hardware equipment, but also by combining the 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, 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.

3. Avoid multi-head cooperation, try to make plastic molds and product processing through one-stop:

1. With qualified molds (the test pieces are qualified), batches of qualified products cannot 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.

2. With a good mold, there is also a good forming process, which is a one-stop cooperation, try to avoid multi-head cooperation.
