Surface Treatments and Finishes
Investment casting surface treatments
There are many different post cast surface treatments that can be applied to investment castings. These treatments vary from simple rust protection of carbon and low alloy steels to complete corrosion enhancing polishing and chemical conversion treatments. Stainless steels are typically electro polished if situated in marine environments, for example, or pickled and passivated if sited in less aggressive environments.
Investment casting surface finishes
Investacast typically achieves a 3.2 Micron surface finish on investment castings. However, the cast surface finish can vary according to the alloy grade and product section size.
As cast surface finish can be altered, corrosion resistance can be enhanced and improved by undertaking various post cast finishing processes. Investacast can provide a range of treatments which are carried out either on-site or via our approved sub contractors. More and more of our customers are benefiting from the extensive range of investment casting finishes that we have to offer.
These processes/treatments include :
Clear Chemical Film Coating
Electroless Nickel Coating
The diversity of treatments is extensive, making Investacast your “one stop shop” casting supplier.
