Shanghai Daoqin Plastics Co., Ltd.

         plastics mold can nitrogen 化处理. USA, China, 香港, standards 编号: AISI H13, DIN: (Europe)1.2344; Japan SKD61, types 钢材出厂 hardness is: HB185~HB230 must hot 处理.

         use in plastics mold upper hardness generally is 480~520HRC, can nitrogen 化处理, due to must need hot 处理, processing relatively is difficult, in mold price upper comparison 贵一, is must need hot to 40HRC above hardness, mold generally use machine processing comparison difficult, therefore in hot 处理之 front need 先做工 parts coarse processing, its is: water 孔, 螺钉孔, and 攻牙必 must good 才进行 hot 处理, need heavy 做, that is 费时失事, types 钢材也 very use in plastics mold upper, therefore has very more Brand, commonly used Brand is: 一胜百(ASSAB)编号 is: 8407;德胜(THYSSEN)编号 is GS344ESR or GS344EFS. (generally use in parts is GS344ESR, use in parts is GS344EFS); Japan large made 钢DAIDO STEEL HI(Japan more 数指定 use), has very more Brand, due to commonly used, therefore can 尽录.

        X45 Ni Cr Mo 4 cold as 钢, AISI 6F7 Europe 编号: DIN 1.2767, types 钢材出厂 hardness HB260, must need hot 处理, generally hardness is 500 ~ 540HRC, Europe comparison commonly used 此钢, tough property good, light 效果也 non good, due to in 华南 区不普遍, therefore Brand more, 如, 德胜(THYSSEN)GS767.

        X42 Cr 13(不锈钢), AISI: 420 STAVAX DIN: 1.2083 出厂 hardness HB180~240, must need hot 处理, hardness 480~520HRC, combined nitrogen hot 处理(锐角 方会 crazing). corrosion resistant and light 效果良 good, therefore generally transparent parts and has property material, 例如: PVC and anti material, V2, V1, V0 type plastics very combined suitable types 钢材, 此钢材也 very use in plastics mold upper, Brand very more, 如, 一胜百(ASSAB)S-136ESR.

        德胜(THYSSEN)GS083-ESR, GS083 GS083VAR; using/adopting need attention/notes, if is transparent parts, that and 动模镶 parts need GS083ESR(据钢厂资 material ESR electrical heavy solvent is improve/increase 钢材 晶体 uniform, light more 佳), is transparent parts parts generally must need high light degree, can selection GS083, is price comparison 廉宜一, effect/influence mold quality, material has 时客户也会 requirements used as 模架, is anti 锈关系, can ensure cooling pipeline water 畅顺, to production cycle stability, types has very more Brand, can 尽录.

        X 36 Cr Mo 17, DIN: 1.2316, AISI 420 STAVAX, hardness HB265~380, 视乎钢厂 specifications, if is transparent parts generally using/adopting 此钢材, is light to high light degree 时, due to hardness very easy has 坑纹, meanwhile in 啤塑也 very easy has 花痕, need again light, therefore also is use 1.2083 ESR经 hot 处理调质 hard 至480 ~ 520HRC very more 麻烦(although hardness high, machine 械切削 relatively easy, mold formed cycle short 一).

         using/adopting large more is anti function in and other price mold upper, has plastics material, upper and PVC, V1, V2, V0 type, use in plastics mold upper very 普遍, Brand more. 一胜百(ASSAB)S-136H, hardness is HB290~330, 德胜钢厂(THYSSEN)GS316(HB265~310), GS316ESR (30~34HRC), GS083M(HB290~340), GS128H(38~42HRC), Japan large 同(DAIDO) PAK90(HB300~330).
