什么是失蜡铸造?
失蜡铸造(Lost Wax Casting / Investment Casting)是一种古老的金属成型工艺,距今5000年。现代珠宝业用它制作几乎所有复杂银饰:镂空吊坠、花纹戒指、立体耳环。
工艺流程
- 制蜡模:3D打印或手工雕蜡,制作单个首饰蜡模
- 组树:把几十个蜡模焊接在蜡柱上,组成"蜡树"
- 制壳:蜡树浸入石膏浆料,重复涂挂6-8层
- 脱蜡:高温蒸汽/烤箱把蜡熔失,留下石膏空腔
- 浇铸:925银加热到900°C熔化,倒入石膏壳
- 敲壳:冷却后敲碎石膏,得到银树
- 后处理:剪件、执模、抛光、电镀
精度与成本
失蜡铸造精度可达±0.1mm,能做出0.3mm的镂空细节。起订量通常50件起,单价随批量递减:50件单价最高,500件降20%,1000件降35%。
