haomei aluminum plate not only has a strict demand for its strength and tenacity but the surface properties of mold are very important for the performance and service life. haomei aluminum mold plate surface treatment technology, is through the surface coating, surface modification, or composite processing technology, mold surface morphology, chemical composition, structure and stress state, in order to obtain the required surface performance of the system engineering.
haomei aluminum mold plate from surface treatment on the way, and can be divided into: chemical method, physical method, physical and chemical methods and mechanical methods. Although designed to improve the surface performance of the mold new technology constantly emerging, but mainly in the mold manufacturing is widely applied nitriding and carburizing and hardening film deposition. Nitriding process with gas nitriding, ion nitriding and liquid nitriding, in every way of nitriding, there are several kinds of nitriding technology, can adapt to the requirement of different steel grade artifacts. Because nitriding technology can form the surface of the excellent properties, and nitriding process with steel quenching process has the good coordination, nitriding temperature is low, at the same time without fierce cooling after nitriding, the mould deformation, therefore the mold surface strengthening is earlier by nitriding technology, is also the most widely used.
haomei aluminum mold plate, the purpose of carburizing is mainly in order to improve the overall strength of the mold toughness, namely mold work surface with high strength and abrasion resistance, this idea is the introduction of technology, with lower material, by carburizing and quenching instead of higher-level material, thereby reducing the manufacturing cost. Hardening film deposition technology is now more mature of CVD and PVD. In order to increase the bonding strength of the coating surface, now developed a variety of enhanced CVD and PVD technology. Current technology condition, the hardening of the high cost of film deposition techniques, still only applied on some precision, long life molds, if adopt the way of setting up heat treatment center, the coating will greatly reduce the cost of hardening membrane, more die if using this technique, can improve the level of mold manufacturing in China as a whole.
