笔记本 front cover/cap sheet/plate

        传统 upper, 笔记本 cover/cap sheet/plate use material is high flow reinforcement flame retardant PC or 者PC/ABS alloy lower, rear 随 笔记本 toward light thin and large more function direction development, 笔记本 cover/cap sheet/plate use material has versus 当一部 separation toward flame retardant reinforcement PA, this 样做 一 large benefits is can in increase fiber add amount lower, utilizing nylon high flow property and crystallization property, reduce product injection molding difficult degree high strength and tough property. however modified nylon material disadvantages very obvious: high water absorption made parts injection molding rear 形变, and nylon flame retardant system price and for material force property can negative effect/influence, made modified nylon material application in more thin, more large 笔记本 front cover/cap sheet/plate upper. is solution this issues, year modified material and 各笔记本 large 厂都不约而同 目 light poly in PPS upper. although Raw Materials cost high other engineering plastics, 但笔者认 is PPS below/following features, it in 笔记本 front cover/cap sheet/plate this application upper has other resin can ratio 拟 独 to advantages:

        本征 flame retardant. and PC and PA different, PPS pure resin and its glass fiber (GF) /矿 powder filling composite/compounding material in add flame retardant lower, can light to V-0@0.8mm甚至 more thin thick degree V-0 flame retardant grade 别. although PC and PA has ratio PPS more price and more good force strong/high degree (especially is impact strong/high degree), is add flame retardant formulation (V-0@0.8mm grade 别) PC and PA composite/compounding material cost large upper rise, very more 时候甚至 high tool has and other force strong/high degree PPS材 material.

         ultra- high flow property, this advantages main/primary is for PC而言. new generation ultra- thin 笔记本 front cover/cap sheet/plate (thick degree 0.8-1mm) for/regarding flexural modulus requirements high 达15000 – 17000 MPa(ASTM standards). is in 3C industry cost control pressure lower, formulation design 师往往 by requirements selection cost more low glass fiber (GF), is carbon as is reinforcement filler. for/regarding PC and its alloy 而言, its relatively flow property glass fiber (GF) add amount upper generally ultra- 40 % (flexural modulus can to 10000 MPa, ASTM standards). more high add amount remove heavy effect/influence material flow property formed processing difficult outer, also generate surface fiber exposure, warpage heavy, force property can and other issues. for/regarding semi crystallization property PPS而言, its non high flow property can glass fiber (GF) filling amount light ultra- 50 %, meanwhile in high temperature melt blending extrusion process in, PPS versus relatively 于PC more low viscosity can make glass fiber (GF) relatively low degree and pressure, from in most injection molding products in tool has more long long degree, to 进一步 improves modulus 效果.

         ultra- low water absorption, this advantages main/primary is for PA而言. flow property 而言, high filling PA and PPS不 versus upper lower;而 for/regarding force strong/high degree, and other filling amount PA composite/compounding material also need more advantages. is remove flame retardant made outer, PA应 used for new generation 笔记本 cover/cap sheet/plate made factors is its relatively high water absorption: versus ratio high temperature nylon PA6T 0.6-1 % water absorption, PPS 0.03 % water absorption can 忽略不计. belt/tape rear is PPS products due to water deformation generate product defect rate need ratio and other conditions lower PA products low more.

        独特 metal and more high surface hardness. PPS material engineering 师都知道, block PPS injection molding made parts 跌落桌面时, 会发出PPS has non 常清脆 碰撞声. through made mold and combined mold temperature 搭配, PPS injection molding made parts in 人手 触碰 lower 也会发出 similar metal 声音, its surface 也会如镜面般 light slip, has metal gloss.

         large in type 手持式 power tools 传动连杆

        凡 is 知道PEEK large 名 材 material formulation and process engineering how much for it application has understanding: high high in upper military industry, aviation aerospace, electrical 装备, low 端一点 也 is 石油钻井 equipment or is high automotive machine internal and its resistant temperature parts. however remove this high large upper field/area, PEEK application its already expand to very more 普通民 use tool and plant/unit upper. in 一 笔者 non 常熟悉 案例 in, 一款特殊定 made PEEK composite/compounding material by formed use injection molding 一款手持 power tools 传动连杆(应 manufacturing 商 保密 requirements, this 里不便透露 power tools specific applications and Model/Grade). that to is what causes make PEEK can price low more more is solid metal material 呢?且听笔者 detailed analysis:

         manufacturing detailed machine 辅助模拟 analysis and testing, carbon fiber reinforced PEEK材 material force strong/high degree (flexural modulus > 12000 MPa, flexural strength > 200 MPa, notched impact strength 300 - 400 J/m, ASTM standards) and high temperature resistance property can (连续工 as temperature degree > 200 degree) can full meet/satisfy design requirements, and also has safety 冗余. this is has 以塑代钢 type application basic front 提. its in very more application in, very more metal parts force property can is large large ultra- design demand.

        此款PEEK composite/compounding material large features is its excellent wear resistant and lubricated property can, can achieve 传动连杆 in lubricated conditions lower belt/tape 动连接 parts high speed 运动; meanwhile in time high speed rear, in and parts surface 积累 自 lubricated filler 转移层(例如PTFE)会 make interface friction coefficient 进一步 reduce, make PEEK传动连杆 运动 more add 自如顺畅, 以至于 in power tools full use cycle inner, 都不必 due to 传动连杆 abrasion loss causes more parts or add lubricated 油. 而另一方面, metal 传动连杆则必需 has lubricated or 者滚动 bearings combined can use. 随 传动连杆运动 time increase, need 不断 添 add lubricated or more abrasion loss bearings can ensure machine positive use, large large reduce use efficiency increase tool use cost.

         energy saving environmental protection and more high design degree. use PEEK manufacturing light amount 化传动连杆 again combined upper in to excellent lubricated property can, make product use can consumption has versus degree reduce. meanwhile one-time property injection molding process use not only versus relatively metal process large large reduce mono parts processing cost; also can achieve product outer design fast speed and rise grade (through mold and combined), large improve/increase product speed degree, reinforcement enterprise competition force.

        纵观国 inner PPS and PEEK composite/compounding material market, large separation Domestic product is 仿照国 outer similar grade launch year-on-year glass fiber (GF) /矿 powder reinforcement specifications, overall 售价偏 low, competition force strong/high. especially is in competition more is PPS market, separation 厂家甚至采取以 recycling material / water material again processing new material, or 者以PPS/PA alloy 冒充PPS positive competition is market 份额, heavy market 秩序, loss lower 游客户 and most 终消费者 利益. through above 两 案例 specific analysis can 清楚 看 to, for current situation, has in separation understanding product application and demand upper through innovation formulation design, 并辅以 formed can processing made process, can most 终杀出 price 战 红海, true positive achieve specialty engineering plastics and high add value application.
