Three Important Points For Making Plastic Mold

Three important points for making plastic mold

First, do not only heavy product design, ignoring plastic mold manufacturing.

Some users in the development of products or new product trial, often initially focused on product development and development, neglect and plastic mold production unit communication. After the initial determination of product design, that is, in advance contact with the mold manufacturer has two benefits:

1, can guarantee the design of the product has a good forming process, not because the parts difficult to process and modify the stereotypes design.

2, the design of the mold can be prepared in advance to prevent the hasty consideration of the impact of the duration.

3, the production of high-quality plastic mold, only the supply and demand both sides close cooperation, can ultimately reduce costs, shorten the cycle.

Second, do not only look at the price, from the quality, cycle, service all-round consideration.

1, many kinds of molds, can be divided into ten categories. According to the different requirements of parts materials, physicochemical properties, mechanical strength, dimensional accuracy, surface finish, service life and economy, different types of mold forming are selected.

2, the high precision of the mold needs to use high-precision CNC machine tool processing, and mold materials, forming process have strict requirements, but also need to use/mold technology to design, analysis.

3, some parts due to the special requirements of molding, mold also need to use hot runner, gas-assisted molding, nitrogen cylinder and other advanced technology.

4, manufacturers should have CNC, EDM, wire cutting machine tools and CNC imitation milling equipment, high-precision Grinder, high-precision Three-coordinate measuring instrument, computer design and related software.

5, the general large-scale stamping die (such as auto cover parts die) to consider whether the machine tool has crimping mechanism, or even side lubricants, multi-position progressive. In addition to stamping tonnage also consider punching, feeding devices, machine tools and mold protection devices.

6, the above-mentioned mold manufacturing methods and processes are not owned and mastered by each enterprise. In the selection of cooperation manufacturers must understand its processing capacity, not only to see the hardware equipment, but also to combine the management level, processing experience and technical force.

7, on the same set of molds, different manufacturers sometimes have a big gap. You should not pay more than the cost of the mold, but also should not be less than the cost of the mold. Mold manufacturers like you, to make a reasonable profit in the business. Ordering a much lower price mold would be troublesome to begin with. Users must start from their own requirements, comprehensive measurement.

Third, avoid long cooperation, as far as possible plastic mold production and processing of products through-train

1, have a qualified mold (test pieces qualified), not necessarily can produce batches of qualified products. This is mainly related to the selection of machining machine tools, forming process (forming temperature, forming time, etc.) and the technical quality of the operators.

2, have a good mold, but also have a good shape processing, preferably one-stop collaboration, as far as possible to avoid long cooperation. If the conditions are not available, you must choose a party to be fully responsible, in order to write the contract clearly.
