currently, injection molding parts production injection molding parts processing is and plastics injection molding parts mold 密切关联 industry. injection molding parts product and injection molding parts production efficiency and plastics injection molding parts mold has 密切 联系. statistics, 80% above quality and efficiency and plastics injection molding parts mold has 关. injection molding parts mold in injection molding parts injection molding parts processing important property performance in below/following 几点. 一: injection molding parts mold 交付期, is can 够开始 amount front 提. injection molding parts mold manufacturing injection molding parts processing tube/pipe water is injection molding parts mold manufacturing efficiency important conditions 之一. 二: injection molding parts mold molding cycle, this 点决定 injection molding parts production efficiency. injection molding parts mold design 者 思路 and is injection molding parts mold molding cycle factors, another molding cycle also and injection molding parts production and injection molding parts mold has 关. 三: injection molding parts product quality （ dimensions degree, appearance, strong/high degree ）, main/primary 取决于 injection molding parts mold quality, good injection molding parts mold ensure production product stability property. 塑模材 material classification and basic property can 如今, for injection molding parts process requirements 越 越 high. plastics injection molding parts mold structure structure day complex. in injection molding parts production process in difficult 免出现 product defect. is mold temperature, material temperature and product 出模时 temperature degree high 而导致 deformation; material temperature low, mold sticking, 间隙太 small formed true 空态; demolding difficult, injection molding parts mold material abrasion loss and other causes formed products degree decline; is plastics hot separation understanding or temperature degree low products surface formed effect/influence products strong/high degree. this causes and injection molding parts process and injection molding parts mold material related. in injection molding parts injection molding parts mold industry in, injection molding parts mold material 包括钢材 and has color metal material, commonly used has carbon structure 钢, alloy structure 钢, injection molding parts mold 钢, 不锈钢 and other; has color metal material copper alloy, aluminum alloy, zinc alloy and other. injection molding parts mold for its material use property can requirements and injection molding parts mold parts function has 关, plastics injection molding parts mold formed 形零部 parts tool has below/following basic property can: 一: good force property can. formed 形零部 parts for its material force property can requirements strong/high degree, rigid degree, tough property, surface hardness and wear resistance can; 二: good corrosion resistant property can; 三: good heat resistant property and fatigue resistance; 四: small thermal expansion coefficient. different injection molding parts mold material features 钢材: is application scope most 广, amount most more material. from generally carbon to carbon tool 钢, from alloy tool to hard 钢, from 马氏体实效钢 to hard alloy, can as plastics injection molding parts mold made as material. China alloy output/production volume already tool world front 列. and its it material versus ratio. mechanical properties, 传统 位 and property ratio in relatively high advantages, 钢材占据 整 industry 主导 位. force property can is can 挑剔, is it thermal conductivity 普遍不 high. alloy material 一: copper alloy copper alloy 包括铍 copper and alloy copper. copper main/primary formed separation is copper, another add 0.5%-3.0% 铍 and its it 元素, through hot rear can to 40HRC above. due to 锻造铍 copper alloy tool has high strength, high hardness, high resistant fatigue and corrosion resistant property can, therefore copper main/primary used for injection molding parts mold core parts. copper also has main/primary advantages, high thermal properties, it can made as internal method cooling water type parts, injection molding parts mold type and injection molding parts mold type 腔, utilizing it high thermal properties will plastics to mold cavity hot amount speed expand dispersion 出. alloy copper similar copper in plastics injection molding parts mold in application, is alloy copper is 不含铍元素, due to 铍元素 in and welding is for has 害, therefore in USA and Europe certain field/area, copper is by prohibited use. alloy copper property can and copper versus more, and its thermal properties high copper. 二: aluminum alloy aluminum alloy remove can using/adopting molding processing outer, also can using/adopting property molding processing, therefore aluminum alloy can as is injection molding parts mold core parts use. is aluminum alloy strong/high degree, hardness and heat resistant property 差, electroplating property and welding property 也不理想, therefore can used for small amount production products injection molding parts mold. Ampco copper alloy has large 家族, it 包括铍 copper, alloy copper, aluminum copper and other alloy, widely used in injection molding parts mold 业. lower 面以Ampco copper alloy is 例说明 copper alloy in injection molding parts production in advantages. improve/increase production efficiency: due to Ampco copper alloy thermal conductivity relatively high, most high is injection molding parts mold 钢 10倍, and thermal conductivity 会随 工 as temperature degree improves improve/increase. therefore plastics products in hot amount can speed through injection molding parts mold molding parts to cooling system. improve/increase injection molding parts parts quality:熔 melt plastics in its rear cooling type process in, due to products 几何形状 effect/influence, mold cavity surface temperature degree very difficult uniform 一致, if products cooling speed degree has 差异, that will 会导致 products shrinkage 不均, and generate internal stress, this for products molding quality has effect/influence, heavy will effect/influence product qualification rate. if in hot amount comparison poly 集 区域 using/adopting Ampco copper alloy as block, this can shrink short products overall molding cycle, or overall type 腔, type full using/adopting Ampco copper alloy, due to alloy good thermal properties, can obtain uniform mold temperature, make products uniform cooling shrinkage, decrease/reduce warpage deformation 发生, improve/increase injection molding parts products quality! processing simple, light property can color:Ampco copper alloy in processing 时无需 hot 处理, decrease/reduce is hot 处理引起 deformation, and make processing more is 简便. if selection Ampco copper alloy, this parts can 不设出计 cooling water 道, need and ring cooling liquid 接触就 can to cooling 效果. another, Ampco copper alloy light property can good, selection 适当 抛 light methods, has can obtain 镜面 抛 light 效果. long injection molding parts mold lifespan: injection molding parts mold use lifespan and injection molding parts mold material hardness and for temperature degree force 敏感程 degree has 关. has Ampco copper alloy hardness can to 40HRC above, if 不进行 surface and other 处理, hardness can and hard injection molding parts mold versus 媲美. is Ampco copper alloy tool has high thermal properties, can will injection material material hot amount speed expand dispersion, reduce mold cavity inner hot degree, meanwhile reduce temperature degree force, decrease/reduce mold cavity hot cracks and hot generate trend, improve/increase injection molding parts mold use lifespan. injection molding parts mold design more is simple: in injection molding parts processing 时, plastics processing 者希望 will melt plastics in hot amount speed uniform to cooling system in, is this has shrink short formed cycle, improve/increase plastics products quality. is 钢材 自身 导 thermal properties high, 例如P20 has 38W/m.K, due to copper alloy high thermal properties, injection molding parts mold design engineering can in design cooling system 时不必像 use injection molding parts mold is that in molding parts cooling water upper large 做文章, use copper alloy can decrease low front cost.
