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，正因為牽涉面普遍，因此色差控制技術(shù)同時也是注塑中公認(rèn)較難掌握技術(shù)之一。在實際的生產(chǎn)過程中我們一般從以下幾個方面來進(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。重慶塑料兒童滑板車玩具</p></p><br
