Investment Casting

 

         Investment casting is an advanced metal forming process used to produce metal parts in high quality, functionality and cost-effectiveness. When combined with modern production knowledge and technologies, it can be applied to produce parts of varying degrees of complexity, in virtually any volume and for the broadest possible spectrum of applications.

A highly versatile casting process, lost wax casting has for some time been perceived as a comparatively expensive process. But when compared to alternative processes which require extensive welding or machining, an investment cast component can often dramatically reduce overall part production costs. Of course, investment casting is not the appropriate process for every metal part requirement. However, for many challenging part applications, investment casting offers a proven and cost-effective metalforming solution.

 

WHY INVESTMENT CASTING

 

  • Excellent accuracy and flexibility of design.
  • Useful for casting alloys that are difficult to machine.
  • Exceptionally fine finish surface.
  • Suitable for large or small quantities of parts.
  • Low cost tooling investment.
  • Suitable for most ferrous / non-ferrous metals.
