For prototypes with custom shapes, such as those created through investment casting, corrosion resistance is the utmost importance.

Electropolishing removes embedded impurities for increased part protection and longevity. PHOTOCHEMICAL MACHINING

Photochemical machining is a prototyping process used to create detailed parts. This CASE STUDY process is ideal for manufacturing parts created from extremely thin metal, as they can be machined without distorting the material. // THE PROBLEM The customer was looking to improve the finish of stainless Many companies use photochemical discs with critical holes manufactured by photochemical machining to manufacture their pro- THE BENEFITS machining.

// CORROSION RESISTANCE

To ensure parts last well into the future, they must have exceptional resistance to oxidation. Electropolishing removes the outer layer of metal and its embedded contaminants, improving the corrosion resistance for photochemical machined parts. After parts have been electropolished, they have a smooth surface that greatly reduces the possibility for corrosion sites.
