style="text-indent:25px">如何控制塑料模具制品的色差？色差是注塑中常見的缺陷,因配套件顏色差別造成注塑機(jī)成批報(bào)廢的情況并不少見。色差影響因素眾多，涉及原料樹脂、色母（或色粉）、色母同原料的混合、注塑工藝、注塑機(jī)、模具等，正因?yàn)闋可婷嫫毡?，因此色差控制技術(shù)同時(shí)也是注塑中公認(rèn)較難掌握技術(shù)之一。在實(shí)際的生產(chǎn)過程中我們一般從以下幾個(gè)方面來進(jìn)行色差的控制。消除注塑機(jī)及模具因素的影響：要選擇與注塑產(chǎn)品容量相當(dāng)?shù)淖⑺軝C(jī)，如果注塑機(jī)存在物料死角等問題，盡量更換設(shè)備。對(duì)于模具澆注系統(tǒng)、排氣槽等造成色差的，可通過相應(yīng)部分模具的維修模來解決。必須首先解決好注塑機(jī)及模具問題才可以組織生產(chǎn)，以削減問題的復(fù)雜性。</p><p style="text-indent:25px">塑料模具，是塑料加工工業(yè)中和塑料成型機(jī)配套，賦予塑料制品以完整構(gòu)型和精確尺寸的工具。由于塑料品種和加工方法繁多，塑料成型機(jī)和塑料制品的結(jié)構(gòu)又繁簡(jiǎn)不一，所以，塑料模具的種類和結(jié)構(gòu)也是多種多樣的。我國塑料模具在高技術(shù)驅(qū)動(dòng)和支柱產(chǎn)業(yè)應(yīng)用需求的推動(dòng)下，形成了一個(gè)巨大的產(chǎn)業(yè)鏈條，從上游的原輔材料工業(yè)和加工、檢測(cè)設(shè)備到下游的機(jī)械、汽車、摩托車、家電、電子通信、建筑建材等幾大應(yīng)用產(chǎn)業(yè)，塑料模具發(fā)展的前景是一片生機(jī)。中國全年塑料模具產(chǎn)值達(dá)534億元人民幣左右?你相信嗎?</p><div

style="text-indent:25px">塑料模具并不難，不管塑料產(chǎn)品怎樣變化，對(duì)于來成形此塑料產(chǎn)品的模具而言，它的結(jié)構(gòu)無非就是上述的幾個(gè)方面。而模具之間的差別就在于模具是大還是??？各個(gè)附助零件、附助設(shè)置、附助系統(tǒng)的位置或者方式不一樣。處理死角的方法、結(jié)構(gòu)、大小等有所變化而已。當(dāng)然，要使設(shè)計(jì)出來的模具加工簡(jiǎn)單、裝配方便、壽命長(zhǎng)、價(jià)格適中、成形產(chǎn)品不錯(cuò)，設(shè)計(jì)經(jīng)驗(yàn)特別重要。好的經(jīng)驗(yàn)，可以處理設(shè)計(jì)、加工當(dāng)中出現(xiàn)的問題，對(duì)待設(shè)變也比較有把握。塑料模具中常用到傳動(dòng)系統(tǒng)的地方是注塑機(jī)上液壓傳動(dòng)系統(tǒng)：注塑機(jī)液壓系統(tǒng)的液壓傳動(dòng)：是以液壓油為工作介質(zhì)，通過動(dòng)力元件(油泵)將原動(dòng)機(jī)的機(jī)械能變?yōu)橐簤河偷膲毫δ?，再通過控制元件，然后借助執(zhí)行元件(油缸或油馬達(dá))將壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)負(fù)載實(shí)現(xiàn)直線或回轉(zhuǎn)運(yùn)動(dòng)，且通過對(duì)控制元件遙控操縱和對(duì)流量的調(diào)節(jié)，調(diào)定執(zhí)行元件的力和速度。當(dāng)外界對(duì)上述系統(tǒng)有擾動(dòng)時(shí)，執(zhí)行元件的輸出量一般要偏離原有調(diào)定值，產(chǎn)生一定的誤差。料模具盡管成為時(shí)下誘人的奶酪，但櫻桃好吃樹難栽。寧波塑料汽配模具</p><p style="text-indent:25px">塑料模具一般說來可以被分為哪幾類？寧波塑料汽配模具</p><p style="text-indent:25px">模具設(shè)計(jì)和制造與塑料加工有密切關(guān)系。塑料加工的成敗，很大程度上取決于模具設(shè)計(jì)效果和模具制造質(zhì)量，而塑料模具設(shè)計(jì)又以正確的塑料制品設(shè)計(jì)為基礎(chǔ)。塑料模具設(shè)計(jì)要考慮的結(jié)構(gòu)要素:澆注系統(tǒng)，也就是由注塑機(jī)噴嘴至型腔之間的進(jìn)料通道，包括主流道、分流道、澆口和冷料穴。特別是澆口位置的選定應(yīng)有利于熔融塑料在良好流動(dòng)狀態(tài)下充滿型腔，附在制品上的固態(tài)流道和澆口冷料在開模時(shí)比較易于從模具內(nèi)頂出并予以去除（熱流道模除外）。寧波塑料汽配模具</p></p><br
