【注塑件縮水問(wèn)題解決】不管是注塑件的表面縮凹還是內(nèi)部縮孔，都屬于它的縮水問(wèn)題，往往都是因?yàn)轶w積較厚的部位冷卻時(shí)熔膠補(bǔ)充不足而造成的缺陷。一旦有這類缺陷產(chǎn)生，不管無(wú)論如何加大壓力、加大入水口、延長(zhǎng)注射時(shí)間，注塑件的縮水問(wèn)題還是無(wú)法得到解決。這該怎么辦呢？從以往的實(shí)踐經(jīng)驗(yàn)看，在注塑件常用的原料當(dāng)中，由于冷卻速度快，PC料的縮孔問(wèn)題很難解決，PP料的縮凹和縮孔問(wèn)題也是比較難處理的。因此當(dāng)遇上厚大件比較嚴(yán)重的縮水問(wèn)題時(shí)，就需要采取一些非常規(guī)的注塑技巧。在生產(chǎn)的時(shí)候，首先要保證注塑件出模不變形的前提下，采取盡量縮短冷卻時(shí)間的方法，讓注塑件在高溫下提早出模。因?yàn)榇藭r(shí)注塑件外層的溫度仍然很高，表皮沒(méi)有過(guò)于硬化，工件內(nèi)外的溫差相對(duì)已不是很大，有利于整體收縮，從而減少了注塑件內(nèi)部的集中收縮。由于注塑件總體的收縮量是不變的，所以整體收縮得越多，集中收縮量就越小，內(nèi)部縮孔和表面縮凹程度因此得以減小。其次在注塑件提早出模后，要對(duì)其作適當(dāng)?shù)睦鋮s，使注塑件表面保持一定的硬度，令其不易產(chǎn)生縮凹。但如果注塑件的縮凹問(wèn)題較為嚴(yán)重，適度冷卻將無(wú)法消除，就要采取凍水激冷的方法，使注塑件表面迅速硬化才可能防止縮凹。鎮(zhèn)江注塑件加工外發(fā)常州注塑加工廠商,一對(duì)一設(shè)計(jì)、技術(shù)支持服務(wù)。</p><div

【塑膠件注塑加工冷卻時(shí)間】在注塑件廠家的注塑加工中，塑膠件注塑加工件冷卻時(shí)間約占整個(gè)注塑加工周期的80%。冷卻不良常常導(dǎo)致制品翹曲變形或產(chǎn)生表面缺陷，影響制品的尺寸穩(wěn)定性。合理地安排注塑、保壓和冷卻時(shí)間，可提高產(chǎn)品質(zhì)量和加工率。注塑件廠家解釋道：制件冷卻時(shí)間通常是指塑膠件熔體從充滿塑膠模具型腔起到可以開(kāi)模取出制件時(shí)止的這一段時(shí)間?？梢蚤_(kāi)模取出制件的時(shí)間標(biāo)準(zhǔn)，常以制件已充分固化，具有一定強(qiáng)度和剛性為準(zhǔn)，在開(kāi)模頂出時(shí)不致變形開(kāi)裂。即使是使用同一種塑膠件成型，它的冷卻時(shí)間也隨壁厚、熔融塑膠件的溫度、成型件的脫模溫度及塑膠模具溫度而異。要在所有的場(chǎng)合下能正確地計(jì)算出冷卻時(shí)間的公式目前尚未發(fā)表，而只有在適當(dāng)假定的基礎(chǔ)上進(jìn)行計(jì)算的公式。計(jì)算公式還因冷卻時(shí)間定義不同而異。目前，注塑件廠家通常以三種標(biāo)準(zhǔn)作為冷卻時(shí)間參考依據(jù)。塑膠件注塑加工件壁厚部位中心層的溫度，冷卻到該塑膠件的熱變形溫度以下所需要的時(shí)間；塑膠件注塑加工件斷面內(nèi)的平均溫度，冷卻到規(guī)定制品的出模溫度所要的時(shí)間；結(jié)晶性塑膠件成型件壁的厚部分中心層溫度，冷卻到其熔點(diǎn)以下所需要的時(shí)間，或達(dá)到規(guī)定的結(jié)晶化百分比所需的時(shí)間。</p><p
