style="text-indent:25px">模具中空成型：是把由擠出或注射制得的、尚處于塑化狀態(tài)的管狀或片狀坯材趨勢(shì)固定于成型模具中，立刻通入壓縮空氣，迫使坯材膨脹并貼于模具型腔壁面上，待冷卻定型后脫模，即得所需中空制品的一種加工方法。適合中空成型的塑料為高壓聚乙烯、低壓聚乙烯、硬聚氯乙烯、軟聚氯乙烯、聚苯乙烯、聚丙烯、聚碳酸酯等。根據(jù)型坯成型方法的不同，中空成型主要分為擠出吹塑中空成型和注射吹塑中空成型兩種。擠出吹塑中空成型的優(yōu)點(diǎn)是擠出機(jī)與擠出吹塑模的結(jié)構(gòu)簡(jiǎn)單，缺點(diǎn)是型坯的壁厚不一致，容易造成塑料制品的壁厚不勻。右圖是擠出吹塑中空成型原理示意圖。注射吹塑中空成型的優(yōu)點(diǎn)是型坯的壁厚均勻、無(wú)飛邊，由于注射型坯有底面，因此中空制品的底部不會(huì)產(chǎn)生拼和縫，不僅美觀而且強(qiáng)度高。缺點(diǎn)是所用的成型設(shè)備和模具價(jià)格貴，故這種成型方法多用于小型中空制品的大批量生產(chǎn)上，在使用上沒(méi)有擠出吹塑中空成型方法普遍。舟山模具與制造縮短設(shè)計(jì)周期并提高設(shè)計(jì)質(zhì)量是縮短整個(gè)模具開(kāi)發(fā)周期的關(guān)鍵之一。</p><div
