The main process parameters of injection molded parts include: 1. melt temperature: melt temperature of the melt flow properties play a major role, since there is no specific melting Zhongshan plastic injection molded parts, called the melting point is the temperature range of a molten state, the plastic molecules The structure and composition of different chain, thus affecting their mobility is also different, rigid molecular chain obviously affected by temperature injection molded parts, such as PC, PPS, etc., and flexible molecular chains such as: PA, PP, PE, etc. By changing mobility temperature is not obvious, it should be adjusted according to different materials and reasonable injection temperature. 2. Barrel temperature: melt temperature is very important, plunger cylinder temperature used only guidance. Melt temperature can measure or method to measure the use of air jet nozzle in place. Plunger cylinder temperature setting depends on melt temperature, screw speed, back pressure, quantity and injection molding cycle shot. If you do not have experience in processing a particular level of plastics, start from the lowest setting. In order to facilitate control, radio Liaogang divided area, but not all are set to the same temperature. If the operation or operations for a long time at high temperature, the temperature of the first zone is set to place a lower value, this will prevent premature melting plastic and diversion. Before the start of injection molded parts, make sure the hydraulic oil, hopper closure, mold and plunger cylinders are at the correct temperature. 3. Injection pressure: Melt required to overcome the resistance to advance, direct impact on product size, weight, and deformation, etc., various plastic products of different required injection pressure, for as PA, PP and other materials, to increase the pressure will make it flow significantly improved, the size of the injection pressure determine the density of the product, i.e. the appearance of the gloss. It has no fixed value, but more difficult mold filling, injection pressure increases. 4. Mold temperature: Some plastic materials due to high crystallization temperature, the crystallization speed is slow, requiring a higher mold temperature, somewhat due to the need to control the size and deformation, or release of, or to a lower temperature a higher temperature, such as a PC general require more than 60 degrees, while the PPS in order to achieve a better appearance and improved flowability, mold temperature 160 degrees sometimes Guangzhou injection molded parts, and thus improve the appearance of mold temperature on the product, deformation, size, plastic mold aspects have not arrived in the estimate effect. World tool market is growing in demand. Which Europe, machine tools and cutting tools. And increased application versatility of the tool, replacing a lot of simple single-function tool ever. Future users will be more emphasis on research and development plant tool, not only in the field of materials technology and surface coatings, but also in its production process tool products, the focus on production practices that will help to increase the tool factory in which they are familiar with the field of market competitiveness. At present, the domestic market demand for large continuous mold, according to forecasts, "Twelve Five" period, the total market steady upward trend in the mold, but requires domestic mold must meet user needs in terms of quality, delivery and so on. Moreover, appliance, automotive, plastics industry demand maximum mold. International market in recent years, labor costs increase industrial countries, developing countries, especially the forward shift Southeast Asian countries. Its domestic production of high precision molds based, manual labor into large molds rely on imports. Therefore, the middle and low mold international market potential is huge. As long as the quality of domestic mold could have improved delivery can guarantee the mold export prospects are very optimistic. In addition, the demand for the international market is also a great standard mold. At present, only a small amount of exports. In recent years, the domestic mold industry accelerated restructuring, mainly for large, sophisticated, complex, long-life mold and mold standard growth rate higher than the overall growth rate of the industry; plastic injection molding and compression ratio of the increase, market-oriented the number of professional mold manufacturers and the ability to increase rapidly Zhuhai injection molded parts, injection molded parts, metal injection molded parts Chen Feng leader provided by the Dongguan City Hardware Products Co., Chen Feng.
