In an ordinary injection molding process, when the mold temperature is set low, although the molding cycle can be shortened, a bridging line is likely to occur, resulting in poor appearance quality. On the other hand, when the mold temperature is set high, the appearance quality of the product surface can be improved, but warping, sagging, and dimensional defects are easily generated, and the molding cycle is prolonged to increase the cost.
High-steam injection molding technology can solve the above two problems at the same time. It uses the steam and cooling water generated by the steam furnace to control the temperature of the mold in a molding cycle, so that the advantages of the above two methods can be fully utilized.
First of all, by injecting steam before injection, the temperature of the mold reaches a temperature exceeding the thermal deformation of the resin, and then the molten resin is injected to form a molded product with no surface line and good surface quality. After the molten resin injection is complete, the cooling process begins. With cooling water, the temperature of the mold rapidly drops below the temperature at which the resin thermally deforms. In this way, by accelerating the curing speed of the resin, the molding cycle can be shortened, and problems such as warpage and sagging can be solved.
High-gloss steam injection eliminates dissolved wiring, melting marks, corrugations, and silver lines on the surface of the product, thoroughly solving the surface shrinkage phenomenon of plastic products, and making the product surface finish to a mirror level. The product does not require subsequent processing of the spray, which effectively reduces costs and shortens delivery time. In addition, high-gloss injection molding can also solve the fibrillation phenomenon caused by the fiber-added products, so that the product quality is more perfect. In thin-wall molding, high-gloss injection molding helps to increase the flowability of injection molding and improve product quality and strength. It can also reduce the thick-walled injection molding cycle by more than 70%.
Aode's high-speed fast-cooling hot die temperature machine has a 8-inch LCD True Color Siemens LCD display, touch-type Chinese input, full Chinese interface, and simple operation. The full-closed-loop system controls the detection of input and output temperatures. It uses the actual temperature of the die to feed back the PLC, and changes the number of color images to ensure that the output is accurate and stable. Steam, cold water, and mold temperature display, interlocked with injection molding machine signals with time and action.
High-gap steam injection molding applications are currently used in liquid crystal televisions, computer liquid crystal displays, automotive liquid crystal displays, car lights and optical instruments, etc.
Ord's newly developed high-temperature die temperature machine has three models that are suitable for injection molding machine 600-800 tons and 300-500 tons and 300 tons or less. The most important feature is that it does not use boiler equipment, the whole machine is equipped with high-temperature water heater and Freezer, and increased hot water and cooling water recovery system, compared with the imported machine imported from the current market, with 600 tons of injection molding machine calculation, can save 1160 degrees of electricity per day (by 20 hours/day), can save 12 tons The water (calculated according to 20 hours/day) is calculated by using boiler steam heating. The annual savings are over RMB 170,000. The energy saving effect is significant and the profit is considerable. This is the advantage of Aude high gloss die temperature machine.
In addition to flat panel TV panels, this technology can also be widely used in computer LCD monitors, air conditioners, automotive interior parts and other home appliances, automotive, communications, medical and other industries.
In the high-light injection molding, the most critical depends on the mold, material and mold temperature control machine (referred to as the mold temperature machine). The high light injection mold temperature machine of Aode Machinery Co., Ltd., which has strong research and development capabilities, fills the technical gap in the domestic market.
