Precautions for plastic mold
Time：2022-11-29 16:49:00Views：
一、Don't just focus on product design and neglect plastic mold manufacturing。
When developing products or trial production of new products, some users tend to focus on product development and development at the initial stage, ignoring the communication with plastic mold manufacturers. After the preliminary determination of the product design scheme, it has two advantages to contact 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 mold maker can make design preparation in advance to prevent improper consideration in a hurry and affecting the construction period。
3、To make high-quality plastic molds, only through close cooperation between the supplier and the demander can we finally reduce costs and shorten the cycle。
二、Don't just look at the price, but consider the quality, cycle and service in an all-round way。
1、There are many kinds of moulds, which can be roughly divided into ten categories. According to the part material, physical and chemical properties, mechanical strength and dimensional accuracy、Different types of dies are selected for forming due to different requirements on service life and economy。
2、The molds with high precision requirements need to be processed by high-precision CNC machine tools, and the mold materials and forming processes have strict requirements. CAD/CAE/CAM mold technology is also needed to design and analyze。
3、Some parts have special requirements during molding, and the mold also needs to use advanced processes such as hot runner, gas assisted molding, nitrogen cylinder, etc。
4、The manufacturer shall have CNC, EDM, wire cutting machine tools and CNC profiling milling equipment, high-precision grinder, high-precision three coordinate measuring instrument, computer design and relevant software, etc。
5、In general, whether the machine tool has a blank holder mechanism, even an edge lubricant, multi station progressive, etc. should be considered for large stamping dies (such as automobile covering die). In addition to punching tonnage, punching times, feeding devices, machine tools and mold protectors should also be considered。
6、The manufacturing methods and processes of the above molds are not available and mastered by every enterprise. When selecting a cooperative manufacturer, we must understand its processing capability. It depends not only on hardware equipment, but also on management level, processing experience and technical strength。
7、For the same set of molds, there is sometimes a big gap between quotations from different manufacturers. You should not pay more than the cost of the mold value, nor less than the cost of the mold. Mold manufacturers, like you, should make reasonable profits in business. Customizing a set of molds with a much lower price will be the beginning of trouble. Users must comprehensively measure from their own requirements。
三、Avoid multi head cooperation and try to integrate plastic mold production and product processing。
1、With qualified molds (qualified test pieces), it is not necessarily possible to produce qualified products in batches. This is mainly related to the selection of the processing machine, 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. It is a coordinated process, and try to avoid multi head cooperation. If the conditions are not met, one party should be selected to be fully responsible, and it must be clearly written at the time of contracting。
