First of all, don't just focus on product design, ignoring plastic mold manufacturing.

Some users only pay attention to product development and development when developing trial products or new products, but neglect to communicate with plastic mold manufacturers. After initially determining the product design plan, there are two advantages that can be contacted with the mold manufacturer ahead of time.

1, ensure that the design product has good molding process, and will not change the design because of difficult parts processing.

2, mold production can be prepared ahead of time, to avoid hasty consideration, delay the construction period.

3, the production of high quality plastic mold, only supply and demand closely cooperate, in order to reduce costs and shorten the cycle. Secondly

Do not just look at the price, but also consider the quality, the cycle and the service.

1, there are many kinds of moulds, which can be roughly divided into ten categories. According to the different requirements of parts and materials, choose physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life and economy, choose different types of mold molding.

2. The high precision requirement of the mold requires the use of high precision CNC machine tools, the mold materials and forming process have strict requirements, mold design and analysis need to use CAD/CAE/CAM technology.

3. Some parts have special requirements in forming. The mold also needs advanced technology, such as hot runner, gas-assisted molding, nitrogen cylinder and so on.

4. The manufacturer should have CNC, EDM, linear cutting machine, NC profile milling equipment, high-precision grinder, high-precision coordinate measuring instrument, computer design and related software.

5. For general large stamping dies (such as automobile cover dies), it is necessary to consider whether the machine has side pressure mechanism, whether there is side lubrication, multi-station stepping, etc. In addition to impulse, blanking, feeding devices, machine tools, mold protection devices.

6, the manufacturing methods and processes of the above moulds are not available to every enterprise. When choosing partners, we should not only know their processing ability from hardware equipment, but also combine management level, processing experience and technical strength.

7, for the same set of moulds, the prices of different manufacturers are sometimes quite different. You should not pay more than the value of the mold, nor should you pay less than the cost of the mold. Die makers like you should get a reasonable profit in their business. Ordering a set of molds at a lower price is a tricky start. Users must start from their needs and take comprehensive measures.
