Basic common sense, classification of existing molds, classification of illuminating applications, general classification of molds, hot molds, cold molds, plastic molds. Total external heat treatment can be proportionally used Long and short progress classification: 1st grade: 1 millionth order or higher; 2nd grade: 500,000 to 0,000,000th grade; 3rd grade: 300,000- to 500,000th grade; 4th grade: 100,000 to 300,000th grade 5th grade: 100,000th order or less; 1st grade, 2nd grade, can heat treatment hardness required Favorable cutting performance under the condition, of course, with reduction, on the other hand. Causes Domestically produced imitation materials, etc. Contrast, confusion of steel numbers, reason for inadequate operation Reference material advancement Contrast study, the following material equalization advancement material. After the reform of the mass production of Japan's mass manufacturing equipment, the temporary equipment technology imported into Japan, Europe, Minatodai, etc., Hong Kong general use European beauty technology materials, and Taiwan mold Japanese materials technology.

Injecting plastic molding material used in the injection plastic material. Injecting plastic material for selection. Strongly acidic plastics present PVC, POM, PBT; weakly acidic plastics present PC, PP, PMMA, PA. Corrosive plastics General selection S136, 1.2316, 420 etc. Molding material, Weakly corrosive selectable S136, 1.2316, 420, SKD61, NAK80, PAK90, 718 etc. Product appearance requirement Opposite imitation material material selection, transparency requirement, surface requirement, mold surface requirement, optional material available S136, 1.2316, 718, NAK80, PAK90, 420, transparency requirement, high-level imitation tool application S136, secondary measure 420.

 

300,000 to 500,000 Molding molds for molds, S136H, 1.2316H, 718H, 1.2083H, etc. P20, 718, 738, 618, 1.2311, 1.2711, etc. for molds of 300,000 or less. Opposite ultra-low demanding imitation tool can use S50C, 45 # steel direct imitation embryo type cavity. Cold cropping tool for main use. Nyo: Cold-molded stamping, cold-molding, cold-molding, deep-printing, mold-molding, cold-molding, Japanese-powdered-molding, etc. Cold cropping tool steel  ,. Various kinds of steel tool steel, alloy tool steel, high speed steel powder high speed steel Japanese powder high alloy steel tool steel. After that, cold cropping tools, steel-like recommendation, comparison, comparison, and comparison. Hot work tool  Main use for manufacturing opposition High temperature state condition work progress Pressure processing work tool. Nyo: Die-casting mold, heat-molding mold, mold-molding, mold-molding, etc. Regular heat-working tool steel: Medium-high content additive Cr, W, Mo, V, etc. Alloy elemental alloy tool steel; .. Alloy pressure Molding Tool Opposite Material Requirement Comparison High, Adaptation  pho. H13, SKD61, 8407, etc.
