重慶升降機金屬型鑄造主要適用于大批量生產(chǎn)形狀簡單的有色金屬鑄件，如鋁活塞、汽缸、缸蓋、泵體、軸瓦、軸套等，鑄造過程中，鑄件的質(zhì)量與合金的鑄造性密切相關(guān)，所謂合金的鑄造性是指在鑄造生產(chǎn)過程中，合金鑄造成形的難易程度，容易獲得正確的外形、內(nèi)部又健全的鑄件，其鑄造性就好。應(yīng)該指出合金的鑄造性是一個復(fù)雜的綜合性能，通常用充型能力、收縮性等來衡量。影響鑄造性的因素很多，除合金元素的化學(xué)成分外，還有工藝因素等，掌握合金的鑄造性，采取合理的工藝措施，可以防止鑄造缺陷，提高鑄件質(zhì)量。
Wenzhou Lifts metal casting is mainly suitable for mass production of non-ferrous metal castings simple shapes, such as aluminum pistons, cylinders, cylinder heads, pump, bearings, bushings, etc., Wenzhou freight casting process,casting and alloy casting of quality are closely related, so-called alloy castability refers casting process, the ease of forming the alloy casting, easy access to the proper shape, and the internal sound castings, like its castability.It should be noted alloy casting of a complex combination of properties, usually filling capacity, shrinkage, etc. to measure. Many factors influence the casting of, in addition to the chemical composition of the alloy elements, as well as technology factors, master alloy castability, take reasonable technical measures, to prevent casting defects, improve casting quality.

鑄件冷卻速度快，組織致密，力學(xué)性能好，鑄件精度和表面質(zhì)量較高，實現(xiàn)了“一型多鑄”，工序簡單，生產(chǎn)率高，勞動條件好，金屬型成本高，制造周期長，鑄造工藝規(guī)程要求嚴格。
Wenzhou freight casting cooling fast, compact, good mechanical properties, high casting accuracy and surface quality, achieve "a multi-cast" process is simple, high productivity, working conditions and high metal mold cost, long manufacturing cycle, casting regulations demanding.
