Hot runner mold by heating means the cast system will not be solidified plastic, nor with the article is released, so called non-runner mold. Advantages: 1) No waste 2) reduce the injection pressure, multi-cavity mold 3) can shorten the molding cycle 4) improve the quality of product characteristics for the hot runner molding compound may be employed: 5) a wide range of the melting temperature of the plastic. At low temperatures, good liquidity, high temperature, good thermal stability. 6) sensitive to pressure, without pressure does not flow, but when pressure is applied to the flow. 7) good specific heat, in order to rapidly cool the mold. Available runner plastics have PE, ABS, POM, PC, HIPS, PS. Common runner in two ways: 1) add hot runner mold 2) absolutely hot runner mold. Die die die protector oxtail monitor, also known as mold monitor or electronic eye, the various types of injection molding machines running real-time monitoring, detection and control of mold protection system. In the manufacturing sector mold, many companies large losses in molds, due to the different product specificity, irregularities, despite the use of many mold mold protection measures Sigma monitor, we can not avoid losses caused by mold damage and to persons damage. Mold protection machine vision contrast functions like a computer CPU powerful computing speed of image data in real-time computation of injection molding machine online protection, through analysis of image capture operation of the machine to intelligently monitor the operation of the injection molding machine, which can effectively detecting whether the product is qualified, and in mold residue before check to prevent mold damage folder, its detection accuracy and applicability of the various brands of domestic injection molding machine, are much higher than similar foreign products.
