1. What material is good for hot pressing mold?
1. Recommend hot-pressed die steel HMAX series HMAX new high-red hard, high-strength and high-wear-resistant mold series, of which HMAX-3 die steel is one of the HMAX die steel series, the matrix is pure, the structure is uniform, it is a high-performance chromium-molybdenum-vanadium alloy steel, with good resistance to thermal cracks, cracking, thermal wear and plastic deformation.
2. What materials are used for hot forming molds? 8566 mold steel, anti-collapse and wear-resistant, the performance you want is readily available, especially for this kind of hot pressing conditions that require high heat resistance and high strength, 8566 die steel is better at it.
3. H13 steel (improved version of H11 steel) is the main material of hot forging steel and cold forging die sleeve in mainland China, and it is also a hot work die steel with strong versatility. It is an ideal steel to replace 3Cr2W8V steel, and the service life can be increased by 2-3 times. 4Cr3Mo3SiV(H1 steel has high toughness, high temperature softening resistance and moderate wear resistance.
4. Cemented carbide is an alloy material that is processed and formed by mixing metal powders such as tungsten and cobalt with binders. Tungsten carbide has extremely high wear resistance, hardness and toughness at high temperatures, so it is widely used in making hot pressing molds. Tungsten carbide has high strength and rigidity, and is suitable for machining high-hardness, wear-resistant metal materials.
5. Alloy steel: Alloy steel is a high-quality mold material with high strength, high hardness, high wear resistance and good toughness. The material is suitable for the manufacture of large hot press molds or high-demand molds. Tool steel: Tool steel is a commonly used mold material with high hardness and strength, which is suitable for manufacturing small hot pressing molds.
6. Commonly used hot forging hot extrusion die materials include aluminum alloy, copper alloy, titanium alloy, steel, etc. Aluminum alloy aluminum alloy mold has the characteristics of light weight, good thermal conductivity and strong corrosion resistance. However, the strength of aluminum alloy is low and cannot withstand the action of high temperature and high pressure. Therefore, aluminum alloy molds are suitable for low-pressure, low-temperature, low-speed hot forging and hot extrusion processing.
2. What is hot stamping
1. Thermocompression molding is a molding process in which a preheated polymer is placed into an open heated mold cavity. The mold is then closed and pressure is applied so that the material touches all areas of the mold. Compression forming molds usually use a hydraulic press, and the upper and lower parts of the mold are fixed on the pressing material and placed on the open mold, and then the press is closed.
2. The molds used in hot stamping are generally referred to as hot pressing molds. The structure and design of the hot stamping die are basically the same as those of the cold forming die, and the differences are mainly reflected in the following aspects. (1) Determination of hot stamping process parameters. The parameters different from the design of the cold forming die mainly include: the clearance of the hot pressing die, the calculation of the size of the working part of the convex and concave die, etc.
3. Hot pressing molding is a replication technology that can transfer the structural material on the mold to the polymer matrix by the hot pressing method at the appropriate temperature and pressure.
According to the different contact methods between the mold and the substrate during the transfer process, the hot pressing process can be divided into three types, which are flat pressing, stepping and rolling.
4. Hot pressing mold Hot pressing mold forming is a molding method in which the composite material is first put into an open hot pressing mold. Close the mold and apply pressure to force the material into contact with all areas of the mold while maintaining heat and pressure until the material cures. This process is capable of producing parts of varying lengths, thicknesses, and complexities.
5. Recommended hot-pressed die steel HMAX series HMAX new high red hard, high strength and high wear resistance mold series, of which HMAX-3 die steel is one of the HMAX die steel series, the matrix is pure, the structure is uniform, it is a high-performance chromium-molybdenum-vanadium alloy steel, with good resistance to thermal cracks, cracking, thermal wear and plastic deformation.
6. Hot pressing is the process of heating and pressurizing the slab after paving and forming to make a fiber board with certain mechanical strength and water resistance. Whether it is a wet process for the production of rigid or semi-rigid boards, or a dry process for the production of rigid or medium density boards, they are hot-pressed to become sheets.
