        本文 from automotive plastics parts 皮纹定义, achieve and design and other 方面 展开, belt/tape large 家走入 automotive inner 饰 “纹理” world!

        伴随 automotive industry development trend, 消费者 for automotive inner outer trim parts fine and property 化关注程 degree 越 越 high. plastics parts as is effect/influence automotive inner outer 饰风格 most important factors 之一, and to 美学, 触感, and safety property, can 一定程 degree low product appearance defect, improves inner outer trim parts quality and value, its and market competition important function.

        1, concept elements

        皮纹 is 指生于生 material table/sheet 皮 天然纹路, usually in type or other material 如牛, 鹿, and other surface 自然 纹路;也 can in material 如树木 table/sheet 皮, 断面, sheet/slice and other surface 纹理;随 现代 design concept expand 展, development to other or material product surface 纹理, 如石材纹路, material 纹路, electrical 火花纹路 and other.

other 皮纹

        本文 in “皮纹”, is plastics product surface 纹饰. plastics product due to different, surface 排列, 组织, different, generate coarse 糙, light slip, soft hard 感, performance is different.

        1.1 皮纹按风格 separation below/following 三 方面:

        1）特征 property

        指纹路 mono 元 形状 can use 几何形态 or 象形形态 描述. Common 形态如线状, block 状, block combined and 荔枝形状 and other and other, 如图1皮纹 mono block structure. mono 元 形状 large small, direction, 排列组 combined direction and mono combined hydrophobic degree for macro has important effect/influence.

        2） direction property

         has 皮纹 纹线特征 has obvious direction property, 如图2示, can this type of 皮纹纹线 obvious 脉络走 toward. has mono 元特征 皮纹就没 has direction property, 如图3示. automotive use leather 皮纹没 has direction property relatively less.

        3）层次 property

         leather upper basic is 立体皮纹, 立体皮纹 tool has property, in micro upper performance is in deep degree direction upper 由2～5 different deep degree value formed; in macro upper performance is leather surface saturated lubricating, 层次丰富起伏, 特征 渡自然, to 人 视觉 impact comparison and, can 借助50倍数 放 large 镜 察看层次. lower is type more 层次皮纹.

        1.2 皮纹按 large small separation can separation is below/following types:

        （1） coarse 皮纹:

         is true world already has 皮纹仿 true 演化而, 纹路接近 true 实纹理, comparison fine 腻, has 层次感, can improve/increase inner 饰档次, generally deep degree in 80～150um between. coarse generally used as automotive inner 饰 主皮纹, has very strong/high overall 协调感, need inner combined design 考虑.

        （2） fine 皮纹:

         is types fine 腻 纹路, similar surface 状态, processing process very more, main/primary has 火花纹, 喷沙纹 and other, fine generally is mono 层次皮纹, deep degree in 0～80um between. fine can mono local decoration can and multiple other 纹路进行搭配.

        （3）几何皮纹:

         is 呈现几何规则 纹理, in automotive upper main/primary 体现科技, force amount, and other concept, generally deep degree in 80～150um between. 几何纹 has strong/high direction property and property, large use large large improve/increase its processing difficult degree, price relatively high.

        3, plastics parts design key points

         plastics parts structure design combined property and quality, degree and molding difficult easy related. 经借鉴 industry design experience, for types type inner injection molding material PP and ABS, deep degree for/regarding plastics parts 拔模角 degree requirements separation different:

         parts 拔模角 degree and processing deep degree effect/influence parts demolding property can.

         generally plastics parts 拔模角 degree 需定义 in 0.5° above, for/regarding has trim parts, experience is 13μm deep degree requirements 拔模角 is 1°, ratio 如门护 sheet/plate selection 110μm 皮纹腐蚀时, that requirements front design 拔模角 degree 约8°. 但理论 value 必需结 combined 实际情况, has if method relatively large degree, this block 区域 皮纹 can versus using/adopting shallow 处理. according to molding conditions, material, parts thick and parts high degree and other factors different, deep degree and 拔模角 degree ratio/proportion has different. if 拔模角 degree small 而皮纹太 deep can can formed parts demolding 时出现卡滞 or whitening and other defect phenomenon.

         commonly used deep degree scope/range:

        ① fine 皮纹, deep degree is 0一80μm;②火花纹, deep degree is 20 一40μm, ratio deep degree fine 皮纹, more add fine and;③ wire drawing 纹, deep degree is 20一80μm;④ coarse and 几何纹,皮纹 deep degree is 100 一150μm.

         generally 说, 拔模角 degree and processing deep degree 关系见 lower table/sheet:

         table/sheet 1 拔模角 degree and processing deep degree 关系

        4 皮纹区域定义 basic 原则

        零部 parts 皮纹由主 machine design positive 式公布, generally distribution in can 见区域, high can and low can 见区, parts and parts remove outer. types 皮纹应 used for different material 体效果 different, 而零部 parts different and 搭接部 separation for requirements 各异, therefore 我们期望 in automotive type design stage/phase 即考虑 inner different 区域 皮纹布置 and 定义.

         inner design in 皮纹区域定义 basic 原则如 lower:

        1）仪 table/sheet sheet/plate, sheet/plate, A柱护 sheet/plate and other belongs to high can 见区

         plastics parts surface relatively large, this main/primary need relatively good 皮纹. 立体皮纹层次丰富, gloss and, decoration relatively good, therefore, this separation usually selection more 层次皮纹.

        2） in relatively small plastics parts surface

        如按钮, 旋钮, small electrical appliances function as sheet/plate and other surface, is small, 不适宜风格 versus for relatively large 立体纹 and 普通皮纹, comparison suitable relatively small fine 皮纹, usually use abrasion 砂纹, this make parts and 皮纹看起 精致, 协调.

        3） in 一 不 Common 面

        如储 material box/case inner 侧面, box/case inner 侧面, sleeve/set inner 侧面, and other and other tool has combined function inner can 做普通皮纹以节约 cost.

         another, in mono parts 皮纹腐蚀 and has versus combined parts 皮纹腐蚀时, need its property need maintain 皮纹 连续 property, main/primary nano lower 几点:

        1） mono parts 皮纹腐蚀区域

         generally 都腐蚀 to parts formed parts can is 止, 如图4门护 sheet/plate formed, mono parts 皮纹腐蚀均以 in sheet/plate formed can is 基准.

        2） mono parts R角

        即 parts versus 邻面交接 渡且呈弧形 区域, 皮纹需做 to can 视面往R角 direction 约2～4mm scope/range inner, ensure in 人 视觉 scope/range inner to 方都经 蚀纹处理. 如图5示, table/sheet sheet/plate right 部检修 cover/cap sheet/plate and parts combined 时, outer 露 部 separation is R角 面. if 皮纹没 has to R角, surface 就会感觉皮纹 in 断, effect/influence 美观.

        3）同一 parts has types 皮纹 交接区域:

        如门护 sheet/plate 本体, parts upper different 区域定义 两 types 皮纹, 两者 交接区域皮纹腐蚀 especially need ensure types 皮纹 平缓 渡, usually is for R角 need versus 应 处理, ratio R角稍 shallow or is in 离接缝2-3mm 方开始变 shallow.

         automotive plastics parts not only can improve/increase degree and property, for product type design, structure design and quality tube/pipe 控方面都 has important effect/influence. 本文结 combined summary this key points, can to 各位同仁以借鉴参考.
