黄铜比青铜等其他金属更具延展性, 这使得更容易铸造复杂的细节.
它很容易流入模具, 确保复杂设计和大型零件的高质量结果.
3. 黄铜失蜡铸造工艺
失蜡铸造工艺涉及几个关键步骤来制造高质量的黄铜零件. 这是该过程的细分:
设计和模型创建
第一步涉及创建零件的详细蜡模型. 艺术家或制造商使用各种雕刻工具将蜡塑造成所需的形状.
在这个阶段, 该模型可以定制复杂的细节，可能包括纹理, 精细图案, 或标志.
构建模具
蜡模型完成后, 它涂有陶瓷外壳. 外壳是用细沙和粘合剂的混合物逐层建造的.
每一层之后, 模具经过干燥和硬化，以确保外壳坚固.
层数通常取决于零件的尺寸和复杂性, 较大的部件使用较厚的外壳.
去除蜡
然后蜡模型熔化并从壳中排出, 留下一个反映原始设计的空腔.
这可以通过将模具放入高压釜或烤箱中来实现, 蜡融化的地方, 留下坚实的, 硬化陶瓷模具.
倒黄铜
下一个, 黄铜在温度约为 1,150°C 的熔炉中熔化 (2,102°f).
将熔化的黄铜小心地倒入预热的模具中, 确保它填充型腔的所有复杂细节.
确保最佳的铸造质量, 黄铜通常在真空或压力下浇注，以避免气泡或空隙.
冷却和打破模具
浇注后, 让黄铜冷却并凝固. 一旦铸件充分冷却, 陶瓷外壳破损, 露出黄铜铸件.
在此刻, 除去所有剩余的贝壳碎片, 并且铸造对象已准备好完成.
收尾工作
最后一步涉及清洁, 抛光, 并向黄铜铸件添加任何必要的细节.
该物体可能会经历打磨等过程, 抛光, 和电镀以获得所需的表面光洁度.
在某些情况下, additional patinas or coatings are applied to enhance the visual appeal.
