Compressive strength and the compressive yield strength of the mold is often subjected to high bending strength and bending stress in use, thus requiring the mold material should have a certain compressive strength and flexural strength. In many cases, the compression test and bending test conducted conditions close to the actual operating conditions of the mold (for example, the measured compressive yield strength of the steel mold and punch work has shown more consistent deformation resistance) . Another advantage of the bending test is to be absolute value of the variable, and can be more sensitive to reflect differences in deformation resistance under different heat treatment and texture between different kinds of steel. Alloy steel and high carbon steel parts carbon ratio, high carbon steel tools, molds and other parts, in order to reduce deformation and cracking, often using isothermal quenching methods. The finished piece is heated rapidly quenched slightly above the horse's transformation began isothermal isothermal bath furnace to complete bainite transformation occurs, get lower bainite isothermal quenching operation called quenching. Austempering get is bainite rather than martensite. But with considerable good mechanical properties. The main factor is the restricted cross-sectional size of the workpiece. From the third quarter of 2014, the number of available days of average inventory of iron ore, the overall downward trend was shock-speed steel, mainly due to new production overseas iron ore market is significantly higher than China, the biggest consumer of iron ore new increasing demand, supply and demand pattern of international iron ore market has undergone substantial changes. Secondly SKH-57 high-speed steel, subject to the adjustment of China's real estate industry for 10 months, market confidence in the iron and steel industry, the largest proportion of consumer demand for building materials suffered a serious setback, combined with the previous two years, the steel trade and industry has been a continuous shuffling, steel terminal both weaker demand and trade aspects of the formation of a great impact on market confidence, the steel industry related commodity spot prices hit a low point this year, futures prices also repeatedly refresh the lowest since listing. When the mold to complete production tasks should take different approaches depending on the injection carefully remove residual injection, available copper rod, copper wire and professional mold cleaners remove residual injection mold and other deposits, and then air-dried. Dongguan mold steel disable wire, steel bars and other hard objects to clean, so as not to scratch the surface. Dongguan rust injection mold steel corrosion caused if, to use the grinder polishing and spray anti-rust oil S705 professional high-speed steel, and then the mold in a dry, cool, no dust at the store. In particular for a tire mold cleaning, mold absorb specific wavelengths of laser energy is very small, will not cause damage to the mold surface contaminants (sulfur compounds, inorganic oxides, silicone oils, carbon black, etc.) to absorb large amounts of energy to be instantaneously inflated, vaporized, away from the mold surface SKH-55 high-speed steel, so as to achieve the cleaning effect. Laser cleaning methods are: 1) Laser dry cleaning method, which uses pulsed laser direct radiation decontamination; 2) Laser + liquid membrane method, which first deposited on the surface layer of the substrate film, and then use laser radiation decontamination; 3 ) Laser + inert gas, i.e., while the laser radiation, with an inert gas purging the substrate surface. When the dirt from the surface of the release, it will immediately be blown gas from the surface, in order to avoid contamination of the surface again. Learn from the advanced mode of cooperation overall development layout, attract industry leaders building demonstration of industrial projects, the introduction of domestic research institutes, construction research collaboration agencies to support the development of relevant policies, and strive to 5 years or so to build the annual turnover in the "City of Mineral" demonstration base 50 billion yuan scale.
