style="text-indent:25px">注塑溫度是影響注塑壓力的重要因素。注塑機料筒有5～6個加熱段，每種原料都有其合適的加工溫度（詳細的加工溫度可以參閱材料供應(yīng)商提供的數(shù)據(jù)）。注塑溫度必須控制在一定的范圍內(nèi)。溫度太低，熔料塑化不良，影響成型件的質(zhì)量，增加工藝難度；溫度太高，原料容易分解。在實際的注塑成型過程中，注塑溫度往往比料筒溫度高，高出的數(shù)值與注塑速率和材料的性能有關(guān)，較高可達30℃。這是由于熔料通過注料口時受到剪切而產(chǎn)生很高的熱量造成的。在作模流分析時可以通過兩種方式來補償這種差值，一種是設(shè)法測量熔料對空注塑時的溫度，另一種是建模時將射嘴也包含進去。</p><p style="text-indent:25px">注塑模具溫度對塑件的影響：影響注射模冷卻的因素很多，如塑件的形狀和分型面的設(shè)計，冷卻介質(zhì)的種類、溫度、流速，冷卻管道的幾何參數(shù)及空間布置，模具材料，熔體溫度，塑件要求的頂出溫度和模具溫度、塑件和模具間的熱循環(huán)交互作用等。（1）低的模具溫度可降低塑件的成型收縮率。（2）模具溫度均勻、冷卻時間短、注射速度快可以減小塑件的翹曲變形。（3）對于結(jié)晶性聚合物，提高模具溫度可使塑件尺寸穩(wěn)定，避免后結(jié)晶現(xiàn)象，但是將導(dǎo)致成型周期延長和塑件發(fā)脆的缺陷。（4）隨著結(jié)晶型聚合物的結(jié)晶度的提高，塑料的耐應(yīng)力開裂性降低，因此降低模具溫度是有利的。但對于高粘度的無定型聚合物，由于其耐力開裂性與塑件的內(nèi)應(yīng)力直接相關(guān)，因此提高模具溫度和充模速度，減少補料時間有利的。影響注塑模具壽命的原因熱疲勞龜裂損壞失效。</p><div

style="text-indent:25px">注塑時間：這里所說的注塑時間是指塑料熔體充滿型腔所需要的時間，不包括模具開、合等輔助時間。盡管注塑時間很短，對于成型周期的影響也很小，但是注塑時間的調(diào)整對于澆口、流道和型腔的壓力控制有著很大作用。合理的注塑時間有助于熔體理想填充，而且對于提高制品的表面質(zhì)量以及減小尺寸公差有著非常重要的意義。注塑時間要遠遠低于冷卻時間，大約為冷卻時間的1/10～1/15，這個規(guī)律可以作為預(yù)測塑件全部成型時間的依據(jù)。在作模流分析時，只有當(dāng)熔體完全是由螺桿旋轉(zhuǎn)推動注滿型腔的情況下，分析結(jié)果中的注塑時間才等于工藝條件中設(shè)定的注塑時間。如果在型腔充滿前發(fā)生螺桿的保壓切換，那么分析結(jié)果將大于工藝條件的設(shè)定。注塑過程中壓力包括塑化壓力和注射壓力兩種，并直接影響塑料的塑化和制品質(zhì)量。青島托盤注塑模具定制廠家</p><p style="text-indent:25px">對于熱塑性塑料注射模，不是計劃冷卻系統(tǒng)來冷卻模具（同時加熱模具）。成都日用品注塑模具定做</p><p style="text-indent:25px">淺談注塑模具的模溫控制：熱的傳遞方式有輻射、對流和傳導(dǎo)三種，在模具中塑料帶入模具所產(chǎn)生的熱量借由傳導(dǎo)被模具吸收熱量占 95 %，由輻射、對流散發(fā)到空氣中約有 5 %，在注射加工過程中，溫度的變化是較重要的影響因素，更對于成品的品質(zhì)有極大影響，間接影響生產(chǎn)效率。模具溫度控制方式，是在冷卻管道中流動的液體冷卻模具，由于水相當(dāng)廉價，所以水是作為初級冷卻劑來冷卻模具，水可以通過引導(dǎo)模具縮短快速冷卻時間。通常較冷模具更有效，因為這樣可以有更快的生產(chǎn)周期時間。但是，這不一定是正確的，因為部分材料太冷反而有反效果。注塑模具的熱均衡控制是決定注塑件質(zhì)量的關(guān)鍵之一，如何選擇與控制，要深度結(jié)合產(chǎn)品的結(jié)構(gòu)，性能，作用，要求等，在保證質(zhì)量的同時，將成本控制到較低。成都日用品注塑模具定做</p><p
