3D printing of sand digitization casting process technology
- 摘要:
- 某些零件由于内部结构复杂、尺寸大,通过铸件或棒材内外表面全部加工或者分段加工后焊接的方式效率较低,传统铸造难以解决复杂内型面不加工的问题。采用基于砂型打印的数字化铸造技术生产,减少新产品的研制周期。具有响应速度快、灵活度高、精度高、工艺稳定性高等优点。
Due to the complex internal structure and large size of some parts,the efficiency of welding after full processing or sectional or pingrocess the inner and outer surfaces of castings or bars is low,and the traditional casting is difficult to solve the problem of complex inner surface not processing.Using digital casting technology based on sand printing can reduce the development cycle of new products.It has the advantages of fast response speed,high flexibility,high precision and high process stability.
