Do not just look at the price of plastic mold, from the quality, cycle time, consider a full range of services, many different types of mold can be broadly divided into ten categories. Depending on the requirements of component 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 need to use high-precision CNC machining, and mold material, forming process has strict requirements itw plastic mold, need to use CAD / CAE / CAM mold technology to design and analysis. 3, some parts due to the special requirements of the molding, the need to use the hot runner mold, gas-assisted 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 there are blank machine organizations, and even edge lubricants, and other multi-position progressive. In addition to stamping tonnage also consider red times, feeding equipment, machine tools and mold protection. 6, the mold manufacturing methods and processes, and not every company has mastered. When selecting collaboration manufacturers must understand its processing capacity, not only to see the hardware, but also with the level of management, processing experience and technical strength. 7, for the same set of molds, different manufacturers offer sometimes have a big gap. You should not have to pay a fee higher than the value at the same mold, and should not be less than the cost of the mold. Mold plastic mold manufacturers, like you, want to obtain a reasonable profit in the business. Customize a quote will be much lower mold begins troublesome. Users must request from their own view, a comprehensive measure. Plastic mold processing knowledge points: 1, molds, micro-injection molding processing equipment that require much higher relative to traditional injection: plastic mold processing usually have two trends: the first is the use of mirror spark machining, in order to ensure high-precision degree, it is best to use a graphite electrode EDM, because the loss of graphite electrodes than ordinary copper electrode is much smaller. The second approach is more commonly used by electric mold processing, using electroforming process can ensure very high accuracy, but the disadvantage is the long processing cycle, each hole should be independently processed, as well as in production if there is minor damage can not be repaired only replace the damaged points. 2, in the mold, the mold temperature is also a micro-injection molding is a very important parameter. Faced with the high-end needs of customers, currently more common practice is to borrow ideas in the field of high-gloss plastic, import rapid heating and cooling systems: theory, high mold temperature is helpful for micro-injection molding, for example, can prevent the thin-walled filling difficulties, lack of material But excessive Dongguan mold temperature will bring new problems, such as longer cycle and post mold shrinkage deformation. So introducing new mold temperature control system seems quite important in the injection molding process, the mold temperature increases (which can exceed the melting point of the plastic used), so that the melt can be quickly filled with pvc plastic mold cavity to prevent the melt during filling reduce excessive temperature caused by filling failure; and when stripping, mold temperature can rapidly reduce the temperature is maintained at a slightly lower than the plastic heat distortion temperature, and then the top of the mold. itw plastic mold plastic mold _ _ Rui Shi Plastic Co. offered by Dongguan Rui Shi plastic mold.
