失蜡法（英文lost wax casting），又称脱蜡法，是一种铸造方法，中国古代在青铜器铸造上已经使用这种方法，现代的铸造工艺中称其为熔模精密铸造。南通方鼎精密铸造有限公司采用的失蜡铸造铸造工艺生产系列的碳素钢，合金钢，不锈钢精密铸造零件，采用全自动射蜡机，制壳焙烧流线线生产，节省的人力，有效控制技术质量参数，缩短了铸造流程时间。silicasol investment casting process and silicasol-water glass composite investment casting process. Adopting the most advanced investment casting process, the company has manufactured more than 100 kinds of precision investment castings in stainless steel, alloy steel and carbon steel, etc. The output is over 1000T per year.南通方鼎精密铸造有限公司是一家专业提供精密铸造的公司，期待您的光临！江苏碳素钢精密铸造厂家推荐

南通方鼎铸钢厂的蜡(模)料的线收缩率约为0.9-1.1%。c.熔模存放时，将进一步产生收缩，其收缩值约为总收缩量的10%，但当存放12小时后，熔模尺寸基本稳定。d.蜡模径向收缩率为长度方向收缩率的30-40%，射蜡温度对自由收缩率的影响远远大于对受阻收缩率的影响(射蜡温度为57-59℃，温度越高收缩越大)。（4）制壳材料的影响：采用锆英砂、锆英粉、上店砂、上店粉，因其膨胀系数小，为4.6×10-6/℃，因此可以忽略不计。（5）型壳焙烧的影响：由于型壳的膨胀系数小，当型壳温度为1150℃时，为0.053%，因此也可以忽略不计。（6）浇铸温度的影响：浇注温度越高，收缩率越大，浇注温度低，收缩率越小，因此浇注温度应适当。河北不锈钢精密铸造件南通方鼎精密铸造有限公司为您提供精密铸造，欢迎新老客户来电！

熔模精密铸造的优点就是由于熔模铸件有着很高的尺寸精度和表面光洁度，所以可减少机械加工工作，只是在零件上要求较高的部位留少许加工余量即可，甚至某些铸件只留打磨、抛光余量，不必机械加工即可使用。由此可见，采用熔模精密铸造方法可大量节省机床设备和加工工时，大幅度节约金属原材料。南通方鼎精密铸造有限公司的熔模精密铸造工艺，可以精密铸造各种合金的复杂的铸件，特别可以精密铸造高温合金铸件。如很难加工的曲面内腔，其流线型外廓与冷却用内腔，用机械加工工艺几乎无法形成。用熔模精密铸造工艺生产不仅可以做到批量生产，保证了铸件的一致性，而且避免了机械加工后残留刀纹的应力集中。

当然，砂型铸造生产的铸件精度、表面光洁度、材质的密度和金相组织、机械性能等方面往往较差，所以当铸件的这些性能要求更高时，应该采用其它铸造方法，例如方鼎铸造厂采用熔模（失蜡）铸造生产碳素钢不锈钢合金钢的铸钢零件，精密铸造有硅溶胶和水玻璃两种粘结剂，表面光洁度分别达到Ra3.2-6.3Ra6.3-12.5尺寸精度ISO8062CT4-6CT6-8。Nangtong Founding Precision Casting CO., LTD， furnace melting process, water glass lost wax casting process, silicasol investment casting process and silicasol-water glass composite investment casting process.南通方鼎精密铸造有限公司致力于提供精密铸造，有需要可以联系我司哦！淮安五金配件精密铸造供应商
