國(guó)內(nèi)V法薄膜生產(chǎn)企業(yè)主要有武漢恒德科技有限公司、北京華盾塑料公司、天津市萊沃商貿(mào)有限公司等。其中，武漢恒德科技有限公司是我國(guó)比較大的V法**EVA薄膜生產(chǎn)企業(yè)，該公司現(xiàn)有4條生產(chǎn)線(xiàn)，具備日產(chǎn)12 t不同規(guī)格EVA薄膜的能力。 </p> <p> 該公司不斷改進(jìn)基于EVA的V法**膜，其醋酸乙烯含量(質(zhì)量分?jǐn)?shù)，下同)為18%-20%，維卡軟化點(diǎn)為70℃。添加山茶植物油提煉的外潤(rùn)滑劑等輔料，使其伸長(zhǎng)率較高，縱向達(dá)到717 % ,橫向達(dá)到589，接近日本同類(lèi)產(chǎn)品。目前，V法鑄造用EVA鑄型薄膜的行業(yè)標(biāo)準(zhǔn)正在制訂中。 </p><p style="text-indent:25px">目前，大部分廠(chǎng)家已經(jīng)采用頂桿起模機(jī)（見(jiàn)圖6），甚至自動(dòng)化程度更高的機(jī)械手完成起模動(dòng)作（見(jiàn)圖7）。相比之前的行車(chē)起模和簡(jiǎn)單的千斤頂起模方式來(lái)說(shuō)，起模的安全性和穩(wěn)定性已經(jīng)有了很大進(jìn)步。但是，在越來(lái)越多精密鑄件成形的過(guò)程中，逐漸發(fā)現(xiàn)部分起模頂桿或者機(jī)械手的精度和強(qiáng)度問(wèn)題。主要反映在起模頂桿導(dǎo)柱導(dǎo)套所用材質(zhì)的質(zhì)量和數(shù)量不夠達(dá)標(biāo)，或者不經(jīng)過(guò)應(yīng)有的熱處理工藝，造型起模頂桿強(qiáng)度和剛性不足。再加上加工或安裝精度不夠，造成起模過(guò)程中頂桿的撓曲變形和起模不穩(wěn)，致使鑄型部分位置擦傷破損，影響鑄型完整性，造成鑄件粘砂，甚至塌箱等缺點(diǎn)。四工位造型機(jī)的旋轉(zhuǎn)由氣缸驅(qū)動(dòng)，并有可靠的定位機(jī)構(gòu)，整機(jī)動(dòng)作采用可編程控制器（即PC）程序控制。</p><div

style="text-indent:25px">V法鑄造一般選擇用熱塑性簿膜，要求成型性好，易涂（刷）涂料，方向性小，熱塑應(yīng)力小，對(duì)熱量不敏感，燃燒時(shí)發(fā)氣量小，不產(chǎn)生有害氣體，質(zhì)優(yōu)價(jià)廉。筆者采用EVA薄膜作為V法鑄造塑料簿膜。覆膜成型時(shí)，簿膜置于加熱器下150～200mm,加熱溫度為80～120℃，加熱時(shí)間一般為20～50s。簿膜加熱至鏡面狀時(shí)應(yīng)迅速將其落下覆膜，覆膜后，須檢查簿膜是否與模樣表面緊密貼緊，是否有無(wú)孔洞或破損。對(duì)于某些難以吸膜成型的部位，采取局部強(qiáng)化抽真空措施，調(diào)節(jié)抽氣速度實(shí)現(xiàn)覆膜成型。目前國(guó)內(nèi)有十多個(gè)在建的鑄造工業(yè)園區(qū)，均采用高爐—感應(yīng)爐供應(yīng)鐵液，年產(chǎn)鑄件達(dá)100多萬(wàn)噸。無(wú)錫真空V法鑄造設(shè)備廠(chǎng)</p><p

原輔材料對(duì)于鑄件質(zhì)量有直接的影響，重視原輔材料的使用，理解原輔材料對(duì)工藝過(guò)程及產(chǎn)品質(zhì)量的影響，對(duì)于提升鑄件質(zhì)量具有重要意義。V法鑄造工藝特別強(qiáng)調(diào)薄膜和涂料的使用控制，而耐磨鑄件本身對(duì)冒口補(bǔ)縮要求相對(duì)也較高，因此EVA薄膜，涂料，冒口等材料的使用技術(shù)在V法鑄造耐磨件方面比較關(guān)鍵。尤其是涂料的噴涂控制和烘干技術(shù)，冒口的安放及發(fā)氣量控制，不僅影響鑄件質(zhì)量，同時(shí)關(guān)系著生產(chǎn)作業(yè)效率和生產(chǎn)組織安排。另外，陶瓷管等其他輔助材料也將對(duì)鑄件沖砂和澆注安全性有著重要的影響。
