Gating system, ie from the injection molding machine nozzle to the cavity between the feed channels, including sprue, runner, gate and cold slug. Especially selected gate location should be conducive to the cavity filled with molten plastic flows in good condition, the solid runner and gate attached to articles on cold material at the top of the mold is easy to be removed from the mold and (heat except channel mode). On the whole S-STAR, the financial crisis on the sheet metal industry does have some impact. But the sheet metal industry under the wave of the financial crisis shows a good development trend. Production and sales in domestic and international markets throughout the sheet metal industry in the financial crisis basically complementary balance can be achieved, so the financial crisis on the sheet metal industry has little overall impact on the amount of orders. Boronizing process commonly used in a variety of cold mold, due to the improvement of wear resistance, mold life can be increased several times or ten times. Sometimes the use of medium carbon steel Boronizing can replace high-alloy steel mold. Boronizing hot die can also be used, such as hot extrusion molds. Boronizing brittle layer, the diffusion layer is thin, weak support for the nitrided layer, therefore, can be used boron nitriding or carbonitriding boron to strengthen the transition zone, the hardness changes gently. To improve the brittleness of boride layer, can be boron vanadium, boron and aluminum alloying. Alloying including Chromizing, vanadizing, seepage titanium and other technology, can be used to deal with cold and hot die, including TD method (molten metal infiltration) has been some applications, can improve die life several times and even ten times . The use of the workpiece is heated to a higher temperature and a longer time for the aging treatment aging treatment process, known as artificial aging treatment, when the workpiece is placed at the natural conditions or prolonged storage at room temperature aging phenomenon occurs is called the natural aging treatment. The purpose of the aging process, eliminate the internal stress of the workpiece, stable organization and size of Japan's imports of S-STAR, to improve the mechanical properties. The source of high energy beam heat treatment usually refers laser, electron beam, ion beam or the like. Their common features are: supply of steel mold surface power density of at least 103W / cm 2. Their common features are: fast heating, heating area can be selected according to the needs of small deformation of the workpiece, does not require a cooling medium, the processing environment clean, good controllability, easy to implement automated processing. At home and abroad on the principle of high-energy beam of heat treatment, process etc to invest more research, more mature laser transformation hardening, small and medium-power electron beam treatment of ion implantation S-STAR rod and improve die life terms get the level of applications. From the trend of the domestic steel price index situation, late June, the trend began long products price index was weaker than plate price index. The continuation of this trend in the third quarter, S-STAR tool steel, and the weak trend of long products price index trend of expansion. The third quarter of this year, long products price index trend has been weaker than the price index sheet, and long products price index accelerated in mid-September to late fall when. Behind this is the real estate industry continues to decline in influence. These defects with the increase in the size of the ingot mold and increasingly serious. On the other hand, osteoporosis, dendrimers and carbides must guarantee the elimination of defects such as forging a certain ratio, the smaller the ingot is not desirable. For this contradiction, the general approach is to ensure that the conditions under forging ratio, try using small ingots. Because of the small size of the ingot cooling conditions were better, more dense internal organization ingot casting flaw less serious. For high-alloy (eg Cr12 type ledeburite) steel, generally smaller size should ingot, forging ratio by forging methods to ensure.
