S390M steel mold material _ Yong Wei (certified) _ S390M provided by Shenzhen, Dongguan City, An Yongwei steel mold shop. Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) is specialized in "Die steel, DC53, SKD11.SUS440C, SUS420" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Simon / R. High-speed steel is a high hardness, high wear resistance and high heat resistance of tool steel, also known as high-speed tool steel or steel front. Process performance high speed steel with good strength and toughness, so prices tend to be high-speed steel material several times S390M other die steel materials, the correct use of high-speed steel and proper post-maintenance can significantly enhance the economic efficiency S390M manufacturers, Shenzhen Hang Sheng years of sales of special steel mold steel, summed up a set of methods to use and maintain high-speed steel. The use of high-speed steel: a first step we use advanced equipment online and offline detect mold dimensional accuracy, surface roughness and hardness tested qualified acceptance relatively high speed steel mold material on registration, make storage shelves. 2, the second step in the use of the collar job with a polished die hole, and the diversion mold and die and die pad profiles during assembly, and view, in time to ensure that no mistakes are made to the machine in heating. Note: The high-speed steel mold material furnace heating time can not be more than ten hours, because the heating time is too long, then work with the die hole will be easier cause corrosion or deformation. 3, the third step in a high-speed steel mold material extruded beginning when S390M, it is best to slowly increase the pressure, because the impact force can cause blocking mode. If blocking occurs when the mold, then immediately stop suspense. Avoid working with crushed die hole. Maintenance of high-speed steel: After the high-speed steel mold material unloading, then leave to cool to time one hundred fifty degrees to one hundred and eighty degrees in the slot into the base to cook, it is because of the mold base and cook at high temperatures, it is more likely to be heat shock cracking. And the need to adopt more advanced erosion wash method to recover save lye, shorten the etching time and realize there is no pollution cleaning. The main failure mode of plastic mold wear, corrosion, deformation and fracture ① thermosetting plastic mold surface wear serious extravagant rub, resulting nap S390M steel mold surface roughness becomes larger and dull, this will affect the plastic parts of the appearance. In this case, the mold should periodically remove the polish, after repeated polishing, cavity size and tolerance will fail. In particular, when a plastic containing mica, silica sand, glass fibers and other solid inorganic filler, the cavity will significantly increase the wear, increase the cavity does not cause the surface roughness meter, but also make the size of the mold cavity changes
