Surface Finishing for Sanitary Compliance

In the food and beverage industry, the surface finish is just as critical as the material itself. We offer specialized finishing processes ensuring your sanitary stainless steel machining projects meet strict hygiene standards. A rough surface can trap bacteria and contaminants, so we focus on achieving low Ra values for maximum cleanability and safety.

Electropolishing for Bacterial Resistance

For parts in direct contact with food, we highly recommend electropolishing. This process removes surface material on a microscopic level, eliminating micro-crevices where bacteria can hide. It results in electropolished food processing parts that are easier to sterilize and significantly more corrosion-resistant than standard machined surfaces. This is essential for components like manifolds and filling nozzles that require frequent sanitation.

Bead Blasting and Anodizing for Non-Contact Parts

Not every component touches the product. For structural aluminum frames, brackets, and housing, we provide Type II and Type III anodizing. This hardens the surface and prevents oxidation in humid environments. Bead blasting is also available to create a uniform, non-reflective matte finish that effectively hides machining marks on external equipment covers.

Passivation for Enhanced Corrosion Resistance

To ensure longevity in wet, wash-down environments, our stainless steel components undergo passivation. This chemical treatment removes free iron from the surface of corrosion-resistant CNC machining parts (specifically 304 and 316L), restoring the protective oxide layer. This step is vital to prevent rust formation during frequent chemical cleaning cycles used in food plants.

Achieving Specific Ra Surface Roughness Targets

Food safety regulations often dictate specific roughness averages (Ra). We use precision grinding and polishing to hit exact targets, typically Ra 0.8µm or smoother for food contact zones. Understanding the influence of surface roughness Ra on the performance of parts allows us to optimize your components for both efficient fluid flow and strict sanitation compliance.
