basic parameters

processing process

drying 处理:

due to PA6 very easy absorption water separation, therefore processing front drying especially need attention/notes, if material is use anti water material packaging supply, container maintain 密闭. if wet degree large 于0.2%, in 80℃ above hot gas in drying 16 small 时. if material already in gas in ultra- 8 small 时, 建议进行 temperature degree is 105℃, 8 small above true dry.

熔 melt temperature degree :

230-280℃, for/regarding reinforcement product types is 250-280℃.

mold temperature degree :

80-90℃, mold temperature degree very significantly effect/influence crystallization degree, crystallization degree also effect/influence parts machine features. for/regarding structure parts crystallization degree very important, therefore mold temperature degree is 80-90℃. for/regarding thin 壁, process/workflow relatively long parts 也建议施 use relatively high mold temperature degree. increase large mold temperature degree can improve/increase parts strong/high degree and rigid degree, reduce tough property. if thick large 于3mm, use 20-40℃ low temperature mold. for/regarding glass fiber reinforcement material mold temperature degree large 于80℃.

injection pressure : generally in 750-1250bar between (取决于材 material and product design )

injection speed degree : high speed ( for reinforcement material need micro reduce )

runner and gate :

for/regarding PA6 solid time very short, therefore gate non important. gate 孔径不 need small 于0.5*T( this 里T is parts thick degree ).

if use hot runner, gate dimensions ratio use runner small 一, is hot runner can 够帮助 retardant material solid. if use 潜入式 gate, gate most small 直径应当 is 0.75mm.

features

PA6 chemical material features and PA66 very versus 似, however, it melting point relatively low, but also process temperature degree scope/range very wide. it impact resistant property and resistant solvent understanding property ratio PA66 need good, wet property more strong/high. is parts many quality features need to wet property effect/influence, therefore use PA6 design product need separation this 一点. is improve/increase PA6 machine features, add various modifier. glass fiber is most Common additives, has is high impact resistance property also add combined formed 橡胶, 如EPDM and SBR and other. for/regarding has additives product, PA6 shrinkage 1% to 1.5% between. add glass fiber additives can make shrinkage rate reduce to 0.3%(但 and process/workflow versus direction also need high 一 ). molding shrinkage rate main/primary material crystallization degree and wet property effect/influence. shrinkage rate also and parts design, thick and its it process parameters formed 函数关系.

automotive application overview

PA6 in automotive upper application 广泛, automotive is plastics important and fast speed growth market, PA6 tool has good comprehensive property can, density low, easy molding, design degree large, thermal insulation insulation, but also in mold and cost upper has obvious advantages. PA6 not only tensile strength high, impact property can excellent but also heat deflection temperature (HDT) high, heat resistant, friction coefficient low, wear resistant loss, lubricated, oil resistant, chemical resistance can excellent, but also especially is use glass fiber (GF) or other material filling reinforcement modified, improves material property can and 档次, meet/satisfy most parts and demand. currently PA6 automotive products types type more, dispersion hot device 箱, front 格栅, add hot device 箱, dispersion hot device sheet/slice, toward 柱罩, lamp covers, 吸附罐, gears outer 罩, 风扇叶 sheet/slice, various gears, dispersion hot device water 室, gas device outer housing/shell, gas tube/pipe, control 开关, gas tube/pipe, true 空连接 tube/pipe, safety gas 囊, electrical table/sheet outer housing/shell, water device, 泵叶轮, bearings, sleeve/set, base/seat, 车门 手, 车轮罩 and other, 总之, and automotive machine parts, electrical parts, 车身部 parts and safety gas and other more 部位. its in automotive machine lower parts use amount most large, this is due to automotive toward small type 化, light amount development, machine 室体积 shrink small, temperature degree rise high, requirements machine lower parts more high temperature resistance, 而PA6 through modified, can separation to upper requirements. has industrial analysis is PA6部 parts not only 起保护 function, also has function.
