Select plastic mold to note three matters

Source: AdminPopularity:336Time: 2016-06-23SML

First, not only on product design, mold manufacturing plastic neglect
Some users in the development of new products or product trial, often only the initial focus on product research and development, neglect communicating with plastic molding units. After the initial product design to determine that in advance contact with the mold manufacturers has two advantages:

1, you can ensure that the design of the products are good forming process, the parts will not be difficult to process and modify the design type.
2, mold design before they do in advance to prepare, prevent ill-considered haste, affect the duration.
3, the production of high-quality plastic mold, only the supply and demand sides work closely together in order to ultimately reduce costs, shorten cycle.

Second, do not look at price, from the quality, cycle, considering a full range of services
1, many different types of mold can be broadly divided into ten categories. Depending on the requirements of parts and materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc., to select a different type of mold forming.

2, high precision molds requires the use of high-precision CNC machining, and mold material, forming process, there are stringent requirements, the need to use CAD / CAE / CAM technology to mold design, analysis.

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

4, the manufacturer should have CNC, EDM, EDM and CNC profile milling equipment, high-precision grinding machines, high-precision coordinate measuring instrument, computer design and related software.

5, generally large stamping dies (such as car cover mold) to consider whether the machine has a clamping mechanism, even edge lubricants, and other multi-position progressive. In addition to the tonnage stamping also consider pumping, feeding device, machine tool and mold protection.

6, the mold manufacturing methods and processes, and not every company has mastered. When choosing collaboration manufacturers must understand its processing capacity, not only to look at the hardware, but also with the level of management, processing experience and technical strength.

7, the same set of molds, different manufacturers offer sometimes a big gap. You should not pay higher than the value of the cost of the mold at the same time should not be less than the cost of the mold. Mold manufacturers like you, want to get a reasonable profit in the business. A custom quote will be much lower molds start trouble. The user must from their own requirements, the overall measure.

Third, avoid long collaboration, try to mold making and plastic products processing train
1, with qualified mold (specimen qualified), may not be able to produce a batch of qualified products. This is mainly the selection and processing machine parts, technical quality forming process (forming temperature, forming time, etc.) and the relevant operator.

2, with good mold, but also a good shaping, preferably one-stop collaboration, avoid long collaboration. If the conditions are not met, we must choose the party has overall responsibility, in the contract or contracts must be written clearly.
