style="text-indent:25px">鋼箱梁成型工藝條件模具的溫度、注射壓力、保壓時(shí)間等成型條件對(duì)塑件收縮均有較大影響。模具溫度高，熔料冷卻慢，密度高，收縮大。尤其對(duì)結(jié)晶性塑料，因其體積變化大，其收縮更大，模具溫度分布均勻性也直接影響塑件各部分收縮率的大小和方向性，注射壓力高，熔料黏度差小，脫模后彈性回復(fù)大，收縮率減小。保壓時(shí)間長(zhǎng)，則收縮率小，但方向性明顯。由于收縮率不是一個(gè)固定值，而是在一定范圍內(nèi)波動(dòng)，收縮率的變化將引起塑件尺寸變化，因此，在模具設(shè)計(jì)時(shí)應(yīng)根據(jù)塑料的收縮率范圍、塑件壁厚、形狀、澆口形式、尺寸、位置成型因素等綜合考慮確定塑件各部位的收縮率。對(duì)精度高的塑件應(yīng)選取收縮率波動(dòng)范圍小的塑料，并留有修模佘地，試模后逐步修正模具，以達(dá)到塑件尺寸精度的要求（2）流動(dòng)性在成型過(guò)程中，塑料熔體在一定的溫度、壓力下填充模具型腔的能力稱為塑料的流動(dòng)性。塑料流動(dòng)性的好壞，在很大程度上直接影響成型工藝的參數(shù)，如成型溫度、成型壓力、成型周期、模具澆注系統(tǒng)的尺寸及其他結(jié)構(gòu)參數(shù)。在決定塑件大小和壁厚時(shí)，也要考慮流動(dòng)性的影響。武漢疊合梁繪圖多少錢疊合梁施工簡(jiǎn)單方便，鋼混凝土疊和梁的鋼梁部分可以作為施工的輔助構(gòu)件。</p><div
