Manufacturing of Standard and Custom Washers
At AREM-CNC, we specialize in the precision machining of custom washers, designed and produced according to drawings or under DIN, ASTM, or ISO standards.
Our washers are machined with micrometric precision, ensuring a perfect fit, high strength, and reliability in all types of industrial applications.
We manufacture custom washers for sectors such as energy, petrochemical, valves, construction, marine, and nuclear, where material quality and dimensional accuracy are critical factors for safety and overall system performance.
We offer a broad catalog of CNC-machined washers in various geometries and configurations:
We also develop custom washers combining different shapes, thicknesses, and materials to achieve the ideal performance for each application.
Surface Treatments
To increase the durability and performance of each washer, we apply various surface treatments according to the operating environment:
White zinc plating 5–7 microns
Yellow dehydrogenated zinc plating 12 microns
Hot-dip galvanizing HDG A 153
Mechanical zinc plating
Geomet 321
Silver plating
Electroless nickel plating
Xylan/Xylar 1070–1424
Takecoat 1000

These processes enhance corrosion resistance, improve tribological behavior, and maintain dimensional stability in highly demanding environments.
Each material is selected based on its intended use — thermal resistance, corrosion behavior, compatibility with dynamic loads, or aggressive environments.
