具多重软硬度的组件及其制造方法
【技术领域】
本发明是有关于一种具多重软硬度的组件及其制造方法， 特别是有关于 一种利用共射或双料双射等方式一体成型的组件及其制法者。
【背景技术】
随着科技及社会的进步， 人们生活所需的产品也不断地推陈出新， 且产 品中的组件也朝多重使用机能 （如增加摩擦或具密封效果等） 方向发展， 其 中也有利用组件中各部位软硬度的不同， 来提升组件的使用机能； 但是， 目 前具多重软硬度的组件均采多件式的组合设计， 如中国台湾专利公告第
322118号、 第 269354号及第 352780号等专利数据中， 揭露多种门窗框上使用 的边框导块、上阻风块及下阻风排水块等组件，而所述组件的主体 1主要是以 硬质塑料 a制成 (如图 1至图 3所示：)， 而另一采软质塑料 b制成的构件 2则固设于 所述主体 1的适当位置， 以组设形成一具多重软硬度的组件； 但是， 此种多件 式的组件在制造上， 需配合组件的数量开设等量的模具，分别生产再行组装， 而使组件成本居高不下， 为改善此一状况， 有许多业者是将此类组件改用双 料射出成型方法生产制成， 其内容如下：
现有的双料射出塑料成型是以两次射出成型的步骤来完成， 其第一次射 出成型的步骤： 是将一呈熔化状态的第一塑料先导入至第一射出单元中， 接 续， 再将第一塑料射入至一模具的模穴中， 以形成一组件半成品； 而第二次 射出成型的步骤： 是将模具以旋转或移动的方式将所述组件半成品移至第二 射出单元处， 再将预置于所述第二射入单元内的第二塑料射出， 令其接合于 所述第一塑料所形成的组件半成品上， 以构成一具有双重材质的塑料射出成 型组件。
而中国台湾专利公告第 1281884号公告，是揭露一种无接缝双料射出成型 方法及其制成品， 其包含一模具， 此模具设有一公模与二母模， 所述公模具 有一公模仁， 而所述母模则具有一第一母模及一第二母模， 所述第一母模具 有一第一母模穴及一第一母模仁， 所述第二母模具有一第二母模穴， 其无接 缝双料射出成型方法包含以下的步骤： 组合所述公模与第一母模， 使所述公 模仁与所述第一母模仁紧密结合； 将第一塑料射入所述第一母模穴以成型所 述第一塑料； 将第一母模与第二母模相互置换， 使第二母模与公模结合， 使 所述公模仁与所述第二母模仁紧密结合， 并形成一第一母模仁的穴位空间； 将第二塑料射入所述穴位空间以成型所述第二塑料， 最后形成一制品。 虽然 上述的现有射出成型方法， 固然可接合两种塑料于一组件， 但其需要较复杂 的模具结构， 而且， 模具的置换也会使制程时间增加。
另一种双料射出塑料成型技术， 是属于共射成型技术 (co-injection molding)中的其中一种成型技术， 称之为三明治共射出成型技术， 请参照图 4 所示。 三明治射出成型***设备包含一注射*** 91、 一固定侧固定板 92及一 可动侧固定板 93， 其中， 所述固定侧固定板 92上设有一母模 94， 所述母模 94 具有一母模穴 941。所述可动侧固定板 93上设有一公模 95，所述公模 95具有一 公模仁 951。 所述母模 94与公模 95结合后形成一模穴空间 96， 又所述母模 94 上设有一流道 97，而所述流道 97的两端出口是为一浇口 971，其中近所述固定 侧固定板 92的浇口 971是供与所述注射是统 91相连接， 而另一浇口 971是设于 所述模穴空间 96的壁面上， 令所述注射*** 91的塑料可经由所述流道 97而导 入至所述模穴空间 96之中。
再如图 4所示， 所述注射*** 91具有一注射口 911、 一第一注射器 912及 一第二注射器 913 ;其中，所述第一注射器 912是设于所述第二注射器 913内并 可移动于其中， 又所述第一注射器 912内装有熔化的第一塑料 9A, 所述第二 注射器 913内装有熔化的第二塑料 9B , 改变所述第一注射器 912抵接所述注射 口 911的状态， 可控制所述注射*** 91的运作。
又如图 4所示， 所述第一注射器 912是抵接于所述注射口 911， 并在一预 设的时间内，所述第一注射器 912将所述第一塑料 9A经由流道 97及浇口 971射 入模穴空间 96之内， 使其填充于所述模穴空间 96的部份空间。
另请参照图 5所示， 所述第一注射器 912退离所述注射口 911， 接着所述 第二注射器 913将第二塑料 9B经由流道 97及浇口 971射入模穴空间 96之内， 而 所述第二塑料 9B推挤先前射入的第一塑料 9A, 使第一塑料 9A被推至所述模 穴空间 96的表面， 而第二塑料 9B则被包覆于所述第一塑料 9A之内， 经固化后 形成一射出成型组件， 其为一外部为第一塑料 9A而内部为第二塑料 9B的组 件， 而此种将一塑料包覆于另一塑料中的共射制法一般业界称之为 「三明治 共射成型方法」，且此种成型方法相较于前述的现有双料射出成型方法， 因无 转换模穴的制程， 所以能够节省大量制程时间； 但是， 此类三明治共射成型 方法虽然能节省制程时间， 但在应用上， 目前仍仅局限于将一塑料包覆于另 一塑料内的用途上。
再请参考图 6所示， 是为共射成型技术的另一实施态様式， 其设备与上 述三明治共射成型的设备大致相同，其差异之处在于所述浇口 971上接设有二 注射*** 91 '及 91"， 而所述注射*** 9Γ 内装有熔化的第一塑料 9A, 所述注 射*** 91"中则内装有熔化的第二塑料 9B; 待射出时再以同时或间隔等方式， 将两种塑料经所述浇口 971及流道 97射入至模穴空间 96中，俟固化后所形成的 组件与上述「三明治共射成型技术」相同， 均为一塑料包覆另一塑料的态様， 所以此种具有二注射*** 9Γ及 91"的共射成型设备， 仍属三明治共射成型的 技术范畴， 其同样具有节省制程时间之效， 但在应用上却仍仅局限于将一塑 料包覆于另一塑料内的用途上。
【发明内容】
本发明的主要目的是在提供一种具多重软硬度的组件及其制造方法， 其 主要是利用两硬度互异的塑料依序射入至同一模穴中， 令射出成型后的组件 外部布设有所述两塑料。
本发明的又一主要目的是在提供一种具多重软硬度的组件及其制造方 法，其中所述两硬度互异的塑料于射出成型后，其组件外部除局部的接合外， 所述组件内部中两塑料的接合处是为一不规则状的接合界面， 因而增加两塑 料的接合面积， 能够有效提升两塑料的接合强度。
本发明的再一主要目的是在提供一种具多种软硬度的组件及其制造方 法， 由于所述制法的流程均在同一模穴中射出成型完成， 据此， 除可简化模 具的结构而节省模具成本外， 也因无模穴转换的制程， 而具节省制程时间及 提高生产效率等诸多效益， 因此能以较低的成本生产， 而具提升商场竞争力 的效益。
本发明的另一主要目的是在提供一种具多重软硬度的组件及其制造方 法， 其中所述制法是可依组件所需的使用机能， 调控所述两塑料射出的次序 与时间， 令所制成的组件上可形具多个软硬度不同的区域外， 且因组件软硬 差异可依所需， 而保有组件原有强度外， 也能增加摩擦、 弹性卡掣及密封等 诸多机能。
本发明的另一主要目的是在提供一种具多重软硬度的组件及其制造方 法， 其中所述制法是可用于原设有 0型环的组件， 令制后所得的组件， 其软 质塑料可环设于原设有 0型环的部位上， 而省除 0型环的设置， 进而达到简化 组件数量及节省成本等功效。
为达上述的目的， 本发明采用如下技术方案： 一种具多重软硬度的组件 包含一原质部及至少一异质部， 两者的硬度互为不同且相互接合成一体， 而 所述原质部及所述异质部均至少具有一外露表面， 且所述原质部与所述异质 部相接合处是至少有一呈不规则状的接合界面。
为达上述的目的， 本发明还采用如下技术方案： 一种具多重软硬度的组 件及其制造方法， 其包含步骤： a . 提供一硬质塑料及一软质塑料； b . 熔化 所述两硬度不同的塑料； c .射出所述两呈熔化状态的塑料至一预设的模穴中； d . 待固化后， 所述两硬度不同的塑料是形成一多重软硬度的组件， 且所述组 件内部及表面于所述两塑料的连接处是形成一不规则状的接合界面。
本发明的有益效果为： 由于上述制法可依据组件实际之需求， 而调控所 述两塑料射出的次序与时间， 使所制成的组件上可形具多个软硬度不同的区 域， 以增加组件之摩擦、 弹性卡掣及密封等多项使用机能外， 且由于上述制 法的流程均在同一模穴中射出成型完成， 因而能简化模具结构， 且因无模穴 转换的制程， 而能节省制程时间及提高生产效率等诸多效益， 所以本发明具 有降低组件成本， 提升产品商场竞争力的效果。

为了让本发明的上述及其它目的、 特征、 优点能更明显易懂， 下文将特 举本发明较佳实施例， 并配合所附图式， 作详细说明如下。
请参考图 7所示， 本发明具多重软硬度的组件制造方法的第一实施例， 其所需的射出成型***包含一注射*** 11、 一固定侧固定板 12及一可动侧固 定板 13。 所述固定侧固定板 12上设有一第一模体 14， 所述第一模体 14具有一 第一模穴 141。 所述可动侧固定板 13上设有一第二模体 15， 所述第二模体 15 具有一第二模穴 151，所述第一模穴 141与所述第二模穴 151共同形成一模穴空 间 16。 又所述第一模体 14上设有一流道 17， 所述流道 17的两端出口是为一浇 口 171，其中近所述固定侧固定板 12的浇口 171是供与所述注射*** 11相接连， 而另一浇口 171则与模穴空间 16相通，令所述注射*** 11中的塑料可经所述流 道 17而导入至所述模穴空间 16之中。
续请参考图 7所示， 所述注射*** 11具有一注射口 111、一第一注射器 112 及一第二注射器 113。所述第一注射器 112可移动于所述第二注射器 113内。所 述第一注射器 112内预装有呈熔化状态的第一塑料 A, 而所述第二注射器 113 内也预装有呈熔化状态的第二塑料 B , 通过改变所述第一注射器 112抵接所述 注射口 111的状态， 可控制所述注射*** 11的运作。
再请参考图 7所示， 本发明第一实施例的具多重软硬度的组件制造方法 的第一步骤是： 提供一硬质塑料 A及一软质塑料 B , 在本步骤中， 所提供的塑 料为第一塑料 A及第二塑料 B ,其分别可互换的选自硬质塑料 A及软质塑料 B。
请参考图 7所示， 本发明第一实施例的具多重软硬度的组件制造方法的 第二步骤是： 将所述两硬质不同的塑料熔化并导入至少注射*** 11中。 在本 步骤中， 所述注射*** 11的第一注射器 112内装有熔化的第一塑料 A, 所述第 二注射器 113内装有熔化的第二塑料8。
请参考图 7及图 8所示， 本发明第一实施例的具多重软硬度的组件制造方 法的第三步骤是： 依序射出所述两硬质不同的熔化塑料至一预设的模穴中。 在本步骤中， 如图 7所示， 所述第一注射器 112内装有熔化的第一塑料 A, 移 动所述第一注射器 112至所述注射口 111 , 在一预设的时间内， 第一注射器 112 经由所述流道 17及浇口 171将第一塑料 A射入所述模穴空间 16的局部空间后 停止。
请再参考图 8所示， 所述第一注射器 112退离所述注射口 111， 接着所述第 二注射器 113经由所述流道 17及浇口 171将第二塑料 B射入所述模穴空间 16。 此时， 后射入的第二塑料 B会把先前射入的第一塑料 A推向两旁， 并穿过所述 第一塑料 A后充满模穴空间 16除了第一塑料 A以外的空间。
请参考图 9所示， 是为第一实施例的另一射出成型***， 其是于浇口 171 上接设二注射*** 1 Γ及 11"， 其中所述注射*** 1 Γ内装有熔化的第一塑料 A, 而另一注射*** 11"则装有熔化的第二塑料 B, 接着于射出的过程， 再依序射 出所述两熔化的塑料至模穴空间 16中， 而后射入的塑料则会推挤并穿过前方 的塑料， 直至所述两塑料布满整个模穴空间 16为止。
请再参考图 10A所示， 上述两实施态样， 于模穴空间 16内的硬质塑料 A 及软质塑料 B固化形成一组件后，所述第一塑料 A于组件上是形成一原质部 a, 而所述第二塑料 B则形具成一异质部 b， 且所述异质部 b包含一位于所述原质 部 a芯部的部份， 以及一穿越所述原质部 a而在其后方形成的部份， 而且所述 原质部 a与异质部 b之间有呈不规则的接合界面 c。
由上述内容得知， 本发明第一实施例是可在一模穴空间 16中依序射入两 硬度互异的塑料并使其固化， 以形成一具有两种材质的一体成型组件， 且于 所述组件上所述原质部 a及异质部 b除具有外露表面外，所述异质部 b因局部被 包覆于所述原质部 a中， 因而可增加两者接合的稳固性及其强度。
再者， 虽然在本发明第一实施例的具多重软硬度的组件制造方法中， 先 射入的所述第一塑料 A固化形成的为一原质部 a， 而所述第二塑料 B形成一异 质部 b。但本发明不受限于此结构顺序， 另一种情况是： 先射入的所述第一塑 料 A固化形成的为一异质部 b， 而所述第二塑料 B形成的为一原质部 a。 也即， 上述方法不限定先射入的塑料的硬度大于或小于后射入的塑料。 所以， 所述 第一塑料 A的硬度可能大于或小于所述第二塑料B。 例如， 在一实施例中， 硬 度较大的塑料为高密度聚乙烯 (PE：)、 聚丙烯 (PP) 、 ABS或尼龙 (NYLON)等其 中一种， 而硬度较小的塑料为低密度聚乙烯 (PE：)、 热可塑性橡胶 CTPR：)、 聚氯 乙烯 (PVC：)、 热可塑性聚胺酯 (TPU)等其中一种。
请再参考图 10B所示， 其揭示本发明第二实施例的具多重软硬度的组件。 其相似于本发明的第一实施例的具多重软硬度的组件， 但不同之处在于： 通 过改变预设的射入时间与射入点的位置或射入点数量， 以使所述不规则的接 合界面 c进一步形成一较宽的界面， 而所述较宽的接合界面 c， 具有介于第一 塑料 A与第二塑料 B之间的硬度， 且其硬度可以是多重的。
如上述的本发明第一或第二实施例的具多重软硬度的组件及制造方法， 可以用来制造具有多重软硬度需求的组件， 如一容器， 并可为盆体、 篮体或 盘体等等。
如图 11所示， 其揭示本发明第三实施例的具多重软硬度的盆体。 一射出 成型盆体 2经由第一或第二实施例的制造方法所制成， 所述盆体 2的大部份由 原质部 a所形成， 而所述盆体 2的底部 21与放置平面接触的部份， 则由异质部 b 所形成， 其中所述原质部 a与异质部 b的细部构造特征相似于第一或第二实施 例， 所以在此不再予以详细绘示或说明。 在第三实施例中， 若所述异质部 b 由较软质的塑料所制成时， 可增加所述底部 21与放置平面间的摩擦力， 以防 止所述盆体 2在放置平面上滑动。或者，所述异质部 b由较硬质的塑料所制成， 则可以增加所述盆体 2的底部 21与放置平面间的摩耗，以符合不同的使用环境 需求。 也就是说， 本发明并不限定组件的某一部位， 要使用硬质或软质的塑 料制成，而是依照组件所述部位所需要的特性来决定要使用何种硬度的塑料。
再者， 上述的本发明第一或第二实施例的具多重软硬度的组件及制造方 法， 也可用于门窗零件， 如一边框导块、 一上阻风块及一下阻风排水块等， 所述些门窗零件的主体通常使用较硬的塑料形成一原质部 a，可使得安装的嵌 配或螺固状态能更稳固。 另外， 在所述些门窗零件与门窗框接触或摩擦的部 位， 则使用较软的塑料形成异质部 b， 以增加门窗零件的气密性， 并可减少因 摩擦而产生的噪音。 所述原质部 a与异质部 b的细部构造特征相似于第一或第 二实施例， 所以在此不再予以详细绘示或说明。
请参考图 12A所示， 其揭示本发明第四实施例的具多重软硬度的边框导 块的侧视图。所述边框导块 3的主体为一嵌入部 31，所述嵌入部 31的外侧设有 若干个补强肋 32， 又所述嵌入部 31的一端设有一滑槽 33， 所述滑槽 33内侧设 有若干个档板 34， 其中所述嵌入部 31为硬质塑料构成的原质部 a， 而若干个档 板 34是为软性塑料构成的异质部 b; 再者， 所述补强肋 32是可依实际需求， 调 节所述两塑料的射出次序， 令所述补强肋 32可形成原质部 a、 异质部 b或接合 界面 c等其中一种。
请参考图 12B所示， 其揭示本发明第四实施例的具多重软硬度的边框导 块的使用状态图。 所述边框导块 3是插设于一活动窗框 C内， 所述边框导块 3 的滑槽 33则跨置于一固定窗轨 D上， 所述活动窗框 C可沿固定窗轨 D滑动。 由 于所述嵌入部 31为硬质塑料构成的原质部 a， 所以使所述边框导块 3可稳固地 嵌入活动窗框 C内。另外， 由于所述若干个档板 34为软性塑料构成的异质部 b， 而当所述档板 34受到所述固定窗轨 D的挤压时， 所述檔板 34是可更佳地贴合 于所述固定窗轨 D上， 以防止外部空气的溢入， 而增益气密的效果； 另同时 所述等补强肋 32也因触及所述活动窗框 C的内壁面而行顺向曲弯变形， 而弹 性卡掣于所述活动窗框 C中， 使所述边框导块 3能更加地紧密充塞于活动窗框 C。
请参考图 13A所示， 其揭示本发明第五实施例的具多重软硬度的上阻风 块的侧视图。所述上阻风块 4的主体为一固定板 41，所述固定板 41设有若干个 鳍片 43， 其中所述固定板 41为所述原质部 a， 而所述鳍片 43为所述异质部 b， 且所述固定板 41与鯖片 43的交接处是为不规则的接合界面 c。
请参考图 13B所示， 其揭示本发明第五实施例的具多重软硬度的上阻风 块的使用状态图。 所述阻风块 4固设于一固定窗轨 D上， 所述固定窗轨 D上另 组合有一活动窗框 C, 所述活动窗框 C可沿固定窗轨 D滑动。 由于所述固定板 41为硬质塑料构成的原质部 a， 使得所述阻风块 4可稳固地装设于所述固定窗 轨 D内， 且由于所述若干个鳍片 43为软性塑料构成的异质部 b， 其受到所述活 动窗框 C的挤压 b会弯曲变形， 因而能借助所述阻风块 4的弹性变形， 阻绝两 者间空隙的产生， 而达更佳的阻风功效。
如图 14A所示， 其揭示本发明第六实施例的具多重软硬度的下阻风排水 块的侧视图。所述下阻风排水块 5的主体为一固定板 51，所述固定板 51设有若 干个阶梯状鳍片 53，所述固定板 51为原质部 a， 而所述等阶梯状鳍片 53为异质 部 b， 且所述固定板 51与所述阶梯鯖片 53的交接处是为不规则的接合界面 c。
请参考图 14B所示， 其揭示本发明第六实施例的具多重软硬度的下阻风 排水块的使用状态图。 所述下阻风排水块 5是卡固于一固定窗轨 D上， 所述固 定窗轨 D上另组合有二活动窗框 C, 所述活动窗框二 C可沿固定窗轨 D滑动。 由于所述固定板 51为硬质塑料构成的原质部 a， 所以使得所述阻风排水块 5稳 固的固设于所述固定窗轨 D内。 另由于所述若干个阶梯状鳍片 53为软性塑料 构成的异质部 b，其受到所述二活动窗框 C的挤压，迫使所述鳍片 53弯曲变形， 以阻隔空气的进入， 而增益阻风的效果。
请参考图 15所示， 本发明第七实施例的具多重软硬度的组件制造方法。 其所需的射出成型***包含一第一注射*** 60、 一第二注射*** 61、 一固定 侧固定板 62及一可动侧固定板 63。 所述第一注射*** 60内装有熔化的第一塑 料 A , 所述第二注射*** 61内装有熔化的第二塑料B。 所述固定侧固定板 62 上设有一第一模 64， 所述第一模具有一第一模穴 641。 所述可动侧固定板 63 上设有一第二模 65， 所述第二模 65具有一第二模穴 651， 所述第二模穴 651与 所述第一模穴 641共同形成一模穴空间 66。所述固定侧固定板 62与所述第一模 64之间设有第一流道 67及第二流道 68。 所述第一流道 67设有至少一第一浇口 671， 所述第一浇口 671是位于所述第一流道 67与所述模穴空间 66交接处， 且 所述第一流道 67是可将所述第一注射*** 60的塑料导入所述模穴空间 66之 中； 所述第二流道 68设有至少一第二浇口 681， 所述第二浇口 681是位于所述 第二流道 68与所述模穴空间 66交接处， 且所述第二流道 68是可将所述第二注 射*** 61的塑料导入至所述模穴空间 66之中。
续请参考图 15所示， 本发明第七实施例的具多重软硬度的组件制造方法 的第一步骤是： 首先提供一硬质塑料 A及一软质塑料 B。 在本步骤中， 所提供 的塑料为第一塑料 A及第二塑料 B , 其分别可互换的选自硬质塑料 A及软质塑 料
再请参考图 15所示， 本发明第七实施例的具多重软硬度的组件制造方法 的第二步骤是： 将所述两硬质不同的塑料分别熔化导入至二注射***中。 在 本步骤中， 所述注射***的第一注射*** 60内装有熔化的第一塑料 A, 所述 第二注射*** 61内装有熔化的第二塑料B。
请再参考图 16所示， 本发明第七实施例的具多重软硬度的组件制造方法 的第三步骤是： 同时射出所述两塑料至一预设的模穴中。 在本步骤中， 在一 预设的时间内， 第一注射*** 60经由所述第一流道 67将所述第一塑料 A射入 所述模穴空间 66之内。
所述第一注射器 60将所述第一塑料 A经由第一流道 67及第一浇口 671射 入模穴空间 66之内。 同时， 第二注射*** 61经由所述第二流道 68将所述第二 塑料 B射入所述模穴空间 66之内。 于是第一塑料 A与第二塑料 B会在模穴空间 66内会合。 这里所谓的同时， 是指第一注射*** 60与第二注射*** 61射出的 时间差异在数秒钟之内， 第一注射*** 60与第二注射*** 61射出的时间还会 因为各别流道及射入口的型式与数量以及各塑料想要达到的分布情形而有所 不同。
请再参考图 17A所示， 本发明第七实施例的具多重软硬度的组件制造方 法的第四步骤是： 固化所述模穴内的硬质塑料 A及软质塑料 B以形成一组件。 在本步骤中， 所述第一塑料 A固化形成一原质部 a， 而所述第二塑料 B形成一 异质部 b， 所述异质部 b位成为所述组件的一局部， 而所述原质部 a成为所述组 件的其它的部份， 并且所述原质部 a与异质部之间有不规则的接合界面 c。
如上所述， 虽然在本发明第七实施例的具多重软硬度的组件制造方法 中， 所述第一塑料 A固化形成的为一原质部 a， 而所述第二塑料 B形成一异质 部^ 但本发明不受限于此结构顺序， 另一种情况是： 所述第一塑料 A固化形 成的为一异质部 b， 而所述第二塑料 B形成的为一原质部 a。 也即， 上述方法 不限定先射入的塑料的硬度大于或小于后射入的塑料。 所以， 所述第一塑料 A的硬度可能大于或小于所述第二塑料B。在一实施例中， 硬度较大的塑料较 佳是可为高密度聚乙烯 (PE：)、 ABS、 聚丙烯 (PP)或尼龙 (NYLON)等其中一种， 而硬度较小的塑料较佳为低密度聚乙烯 (PE：)、 聚氯乙烯 (PVC) 、 热可塑性橡 胶 (TPR：)、 热可塑性聚胺酯 (TPU)等的其中一种。 请再参考图 17B所示， 其揭示本发明第八实施例的具多重软硬度的组件。 其相似于本发明的第七实施例的具多重软硬度的组件， 但不同之处在于： 通 过改变预设的射入时间与射入点的位置或射入点数量， 以使所述不规则的接 合界面 c进一步形成一较宽的界面， 而所述较宽的接合界面 c， 具有介于第一 塑料 A与第二塑料 B之间的硬度， 且其硬度可以是多重的硬度。
如上述的本发明第七或第八实施例的具多重软硬度的组件及制造方法， 可以用来制造具有多重软硬度需求的组件， 如一容器， 其选自盆体、 篮体或 盘体。
再者， 上述的本发明第七或第八实施例的具多重软硬度的组件及制造方 法， 也可用于门窗零件， 如一边框导块、 一上阻风块及一下阻风排水块等， 所述些门窗零件的主体通常使用较硬的塑料形成一原质部 a，可使得安装的嵌 配或螺固状态能更稳固。 另外， 在所述些门窗零件与门窗框接触或摩擦的部 位， 则使用较软的塑料形成异质部 b， 以增加门窗零件的气密性， 并可减少因 摩擦而产生的噪音。
此外， 请再参考图 18所示， 其揭示本发明的另一应用范围为一种具 0型 环效能的塑料组件， 其均可由上述的本发明第一、 第二、 第七或第八实施例 的具多重软硬度的组件及制造方法所制成。 而所述组件 7的大部份由原质部 a 所形成， 而所述 0型环部 71则由异质部 b所形成， 其中所述原质部 a与异质部 b 的细部构造特征相似于第一、 第二、 第七或第八实施例， 所以在此不再予以 详细绘示或说明。在本发明第九实施例中，所述异质部 b由较软质的塑料所制 成， 因此使所述组件 7与其它对应的组件进行组装时， 所述 0型环部 71能被紧 迫而稍微变形， 以产生密封而具防止流体泄漏的功效。 也就是说， 所述组件 7 的 0型环部 71能取代一现有的 0型环， 进而简化所述具 0型环组件 7的构造及 具节省成本的效能。
