First, do not just focus on product design, ignore the plastic mold manufacturing.
Some users in the development of products or new products trial production, often only focus on early product development and development, ignoring and plastic mold production units of communication. Product design program initially identified, that is, in advance with the mold manufacturers have 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, mold production can be prepared in advance to prepare to prevent hurry to consider ill, affecting the duration.
3, the production of high-quality plastic mold, only the two sides with the supply and demand in order to ultimately reduce costs and shorten the cycle.
Second, do not just look at the price, from the quality, cycle, service all-round consideration.
1, a lot of mold types, can be divided into ten categories. According to the parts of the material, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, life, economy and other different requirements, choose different types of mold forming.
2, high precision requirements of the mold need to use high-precision CNC machine tools, and mold materials, forming processes have strict requirements, need to use CAD / CAE / CAM mold technology to design and analysis.
3, some parts due to the special requirements when forming, mold need to use hot runner, gas-assisted molding, nitrogen cylinder and other advanced technology.
4, manufacturers should have CNC, EDM, WEDM and CNC milling equipment, high-precision grinding machines, high-precision three coordinate measuring instrument, computer design and related software.
5, the general large-scale stamping die (such as car cover mold) to consider whether the machine has a blank holder, and even side lubricants, multi-station level and so on. In addition to stamping tonnage also consider the red, feeding device, machine tools and mold protection device.
6, the mold manufacturing methods and technology is not every enterprise has and master. In the choice of collaboration manufacturers must understand its processing capacity, not only to see the hardware equipment, but also with the management level, processing experience and technical strength.
7, the same set of molds, different manufacturers offer sometimes a big gap. You should not pay more than the value of the mold at the same time, it should not be less than the cost of mold. Mold manufacturers like you, in the business to obtain a reasonable profit. Customizing a set of very low molds will be the beginning of trouble. Users must proceed from their own requirements, a comprehensive measure.
Third, to avoid long cooperation, as far as possible plastic mold production and processing products through train.
1, with a qualified mold (specimen qualified), may not be able to produce bulk of qualified products. This is mainly related to the processing of machine tool selection, forming process (forming temperature, forming time, etc.) and the technical quality of the operator.
2, with a good mold, but also a good shape processing, it is best one-stop collaboration, try to avoid long cooperation. If the conditions do not have, we must choose a full responsibility for the parties at the same time must be written clearly.
