V法鑄造用塑料薄膜厚為0.03～0.25mm。覆膜成型是將塑料薄膜加熱軟化，利用真空將薄膜吸附在凹凸不平的模樣表面上（如圖3.2所示）。由于模樣輪廓結(jié)構(gòu)復(fù)雜多樣，要求塑料薄膜具有較好的延伸性，不易產(chǎn)生折痕和破裂，泰州先進(jìn)V法鑄造效果。塑料簿膜在模樣或芯盒內(nèi)的成型能力直接影響鑄件的表面光潔度和尺寸精度，泰州先進(jìn)V法鑄造效果，因而V法鑄造的薄膜須具有以下要求： </p> <p> 好的延伸性，泰州先進(jìn)V法鑄造效果，不得有氣泡滴和***等缺點(diǎn)；<span style="font-size:12px;">成型時(shí)形狀缺點(diǎn)不應(yīng)擴(kuò)展；</span><span style="font-size:12px;">覆膜成型后失去彈性；</span><span

對(duì)于澆注系統(tǒng)的設(shè)計(jì)，不少文獻(xiàn)和資料均有詳盡解說，在此不再贅述，*就注意事項(xiàng)簡(jiǎn)要說明。 </p> <p> 澆注系統(tǒng)盡量采用半開半閉方案，這種扼流型澆注系統(tǒng)可以有效避免高紊流狀態(tài)發(fā)生，可以降低金屬液在充型腔過程中的流動(dòng)速度和對(duì)型壁、坭芯的沖擊，減少鑄造缺點(diǎn)。 </p> <p> 盡量采用陶瓷材料成型澆注系統(tǒng)，避免鋼水長時(shí)間沖刷澆道而造成由于夾砂、夾涂料產(chǎn)生的鑄造缺點(diǎn)。 </p> <p> 盡可能采用中間澆注方式，這樣可以減少因底注造成對(duì)上型壁長時(shí)間烘烤造成塌型、上型凹陷、薄膜和涂料產(chǎn)生的氣孔等，亦可減弱頂注產(chǎn)生對(duì)下型壁和坭芯的沖擊、紊流和裹氣等缺點(diǎn)。 </p> <p> 合理布置冒口，尤其是明冒口布置，一般應(yīng)布置在澆口附近和遠(yuǎn)離澆口的鑄件末端，便于透氣和排氣，易于鑄件成型和減少氣孔。南京真空V法鑄造生產(chǎn)線消除涂料、薄膜氣化產(chǎn)物對(duì)鑄型的強(qiáng)度與負(fù)壓度影響。</p><div style="width:100%;text-align: center;"><img
