Stainless Steel & Plastic Machining

Typically, new systems and water filter replacement parts use components that are made of stainless steel, a hard-to-machine material. Some parts are made from specialty plastics instead. RAND specializes in plastic machining and also prides itself on working with stainless steel, a hard-to-machine metal.
