Analysis of high-gloss seamless injection mold temperature machine

In ordinary injection molding processing, when the mold temperature is set low, although the molding cycle can be shortened, it is easy to produce sink lines and cause poor appearance quality. On the contrary, when the mold temperature is set high, the appearance quality of the product surface can be improved, but it is prone to warpage, sag, size defects, etc., while prolonging the molding cycle and increasing the cost.

High-gloss 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 oven to control the temperature of the mold in a molding cycle, so that the advantages of the above two methods can be brought into play.

Features of high-gloss non-marking injection mold temperature machine:

①7-inch LCD true color LCD display (optional), touch Chinese digital input, full Chinese interface, simple operation.

②The full-closed loop system controls the detection of input and output temperature, and the actual temperature of the mold is fed back to the PLC, and the digital color graph changes display to ensure accurate and stable output.

③Six alarms for high temperature steam or high temperature hot water, cold water, air temperature and pressure, interlock with injection molding machine signals by time and action.

④The whole machine adopts components imported from Europe and America.

⑤Single and double mold temperature detection (optional), the input and output pipelines are made of stainless steel pipes, and multiple sets of input and output interfaces.

⑥The whole machine is equipped with heating, cooling, and cold-heat conversion control functions.

⑦Recovery system of high temperature hot water and cooling water.

First, the temperature of the mold is made to exceed the thermal deformation temperature of the resin by spraying steam before injection, and then the molten resin is injected to form a molded product with no sink lines and good surface quality. After the molten resin injection is completed, the cooling process begins. Use cooling water to quickly drop the mold temperature below the temperature at which the resin is thermally deformed. In this way, by accelerating the curing speed of the resin, the molding cycle can be shortened, and problems such as warpage and sag can be solved.

High-gloss steam injection molding can eliminate the melting lines, welding marks, ripples and silver lines on the surface of the product, completely solve the surface shrinkage of plastic products, and make the surface finish of the product reach the mirror level. The product does not require subsequent processing of spraying, which effectively reduces costs and shortens delivery time. In addition, high-gloss injection molding can also solve the floating fiber phenomenon caused by fiber-added products, thereby making the product quality more perfect. In thin-wall molding, high-gloss injection can help improve injection fluidity and improve product quality and strength. It can also reduce the injection cycle of thick-wall molding by more than 70%.

The high-speed cold and hot mold temperature controller has an 8-inch LCD true color Siemens LCD display, touch-type Chinese digital input, full Chinese interface, and simple operation. The fully closed loop system controls the detection of input and output temperature, feedbacks the PLC with the actual temperature of the mold, and displays the change of the digital color graph to ensure the accuracy and stability of the output. Steam, cold water, and mold temperature are displayed, and time and action are used to interlock with injection molding machine signals.

The newly developed high-gloss mold temperature controller has three models suitable for injection molding machines of 600-800 tons and 300-500 tons and less than 300 tons. The biggest feature is that it does not use boiler equipment. The whole machine is equipped with a high-temperature hot water machine. And the refrigerator, and added the hot water and cooling water recovery system, compared with the imported machine introduced in the market, based on the 600-ton injection molding machine, 1160 kWh of electricity per day (calculated at 20 hours/day) can be saved, which can save 12 A ton of water (calculated at 20 hours/day), compared with the use of boiler steam heating, saves more than 170,000 yuan per year, which has significant energy-saving effects and considerable profits. This is the advantage of Chuanbensite high-gloss mold temperature controller.

In addition to flat panel TV panels, this technology can also be widely used in home appliances such as computer LCD monitors, air conditioners, automotive interior parts, automobiles, communications, and medical industries.
