style="text-indent:25px">注塑過程中溫度的控制：1料筒溫度：注射模塑過程需要控制的溫度有料筒溫度，噴嘴溫度和模具溫度等。前兩種溫度主要影響塑料的塑化和流動(dòng)，而后一種溫度主要是影響塑料的流動(dòng)和冷卻。每一種塑料都具有不同的流動(dòng)溫度，同一種塑料，由于來源或牌號(hào)不同，其流動(dòng)溫度及分解溫度是有差別的，這是由于平均分子量和分子量分布不同所致，塑料在不同類型的注射機(jī)內(nèi)的塑化過程也是不同的，因而選擇料筒溫度也不相同。2、噴嘴溫度：噴嘴溫度通常是略低于料筒較高溫度的，這是為了防止熔料在直通式噴嘴可能發(fā)生的"流涎現(xiàn)象"。噴嘴溫度也不能過低，否則將會(huì)造成熔料的早凝而將噴嘴堵塞，或者由于早凝料注入模腔而影響制品的性能。3、模具溫度：模具溫度對(duì)制品的內(nèi)在性能和表觀質(zhì)量影響很大。模具溫度的高低決定于塑料結(jié)晶性的有無、制品的尺寸與結(jié)構(gòu)、性能要求，以及其它工藝條件（熔料溫度、注射速度及注射壓力、模塑周期等）。合理的注塑時(shí)間有助于熔體理想填充，而且對(duì)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。濟(jì)南透明注塑模具定制</p><p
