Two component injection moulding of bi-material of stainless steel and yttria stabilized zirconia – green part

The two component injection molding (2C-PIM) is a promising technique for production of small, complex and high density, metal-ceramic parts in large scales. This method is a viable option for integrating incompatible functions or properties of the materials in a singular part or component. Thus, th...
