         mold in use process in, need according to production requirements or technology requirements, using/adopting 一定 造 formed production 线, has has attention/notes fine 节时, very more factors formed mold unstable property, this 样会严 heavy effect/influence to mold manufacturing parts use can, therefore in manufacturing 时一定 need attention/notes related stability property issues.

         mold and pressure formed stability property and its effect/influence factors

        何谓 stability property? stability property separation is process stability property and production stability property. process stability property meet/satisfy production combined product tool has stability property process solution/scheme; production stability property production process in tool has stability property production can force.

        先 let 我们 看看 effect/influence mold and pressure formed stability property main/primary factors, separation is: mold material use methods; mold structural parts strong/high degree requirements;冲 pressure material property can stability property;材 material thick degree features;材质 变化 scope/range; tensile retardant force large small; pressure force scope/range; lubricant selection.

         comprehensive effect/influence stability property factors

         value attention/notes is, in pressure formed process in, due to types pressure sheet/plate has chemical formed separation, force property can and and pressure property can related features value,冲 pressure material property can unstable, pressure material thick degree 波动, and pressure 材质 变化,不但直接 effect/influence to pressure formed processing degree and quality,亦 can can mold loss bad.

        以 tensile is 例, its in pressure formed in 便占据 has non important 位. in tensile formed process in, product formed need tool 备一定 large small, solid 定周边适当 distribution force, this type of force pressure equipment function force, 边缘部 separation material deformation retardant force,以 and pressure 边圈面 upper flow retardant force. flow retardant force generate, if is pressure force function,则 mold and material between scratch force is 不够.

         is 此, also must in pressure upper can generate relatively large retardant force tensile 筋,以 increase material retardant force, from make material generate relatively large property deformation,以 meet/satisfy material property deformation and property flow requirements. meanwhile, through tensile retardant force large small and distribution,并 control material toward mold inner flow speed degree and material amount, achieve for tensile parts deformation inner force and its distribution has adjustment, from anti tensile formed product 破裂, 起皱,以 and deformation and other quality issues.

        由 upper can 见, in made pressure process and mold design process in,必 must tensile retardant force large small, according to pressure force scope/range tensile 筋并确定 tensile 筋 形式, make deformation 区域按 need deformation methods and deformation degree formed formed 形.
