New Process Fibre, an ISO 9001:2015 non-metallic stamping company, manufactures flat and specialty washers for the fastener industry using a large variety of materials such as Nylon, Nylon 6, Nylon 6/6, High and Low Density Polyethylene, Polypropylene, PEEK®, Flame Retardant Polypropylene, Acetal, ABS, Mylar®, Teflon™ PTFE, Vulcanized Fibre, Fish Paper, Nomex®, Viton®, Paper Phenolic, PVC, Polycarbonate, Ultem®, Buckfab, and Epoxy Glass.
With over 10,000 washer dies in stock, we can meet your requirements in as little as 1 week – or less! We fabricate washers with outside diameters from 0.093″ to a maximum of 12.000″, thicknesses from 0.005″ to 0.187″, and quantities ranging from just 1 into the millions per order.
Our team has years of experience working a broad range of materials, building their own die-sets in-house, and stamping washers to exact tolerances with an extremely fast turnaround, regardless of order quantity.
We offer a large array of colors, including red, green, blue, yellow, black, orange and white, and provide color matching on certain material options. (Minimum quantities may apply for these special colors.)
All custom washers available in English and/or metric units and can have Pressure Sensitive Adhesive (PSA) applied.
Plastic & Non-Metallic Material Capabilities
A key advantage of working with New Process Fibre is the depth of its material expertise. Each polymer, laminate, or fibre material offers a different balance of strength, flexibility, insulation, and chemical resistance. This allows engineers to select washers that perform reliably in environments involving moisture, vibration, electrical insulation, exposure to chemicals, and many others.
For example, Nylon, Nylon MDS, and Delrin washers provide strength for mechanical assemblies and high wear resistance, while PTFE washers offer low surface energy, friction resistance, and resistance to aggressive media. Nomex and Vulcanized Fibre support electrical insulation needs, and PEEK washers are chosen for demanding environments where temperature stability and mechanical strength are priorities.
This broad material library helps customers match washer performance to the exact demands of their application rather than compromising with a limited set of options.
Precision Stamping and In-House Tooling
New Process Fibre maintains full control over its tooling by building most of our custom die sets in-house. This approach supports tight tolerances, consistent part quality, and fast adjustments during design changes. Because our custom part tooling does not need to be outsourced, customers benefit from shorter lead times and more predictable production schedules.
The stamping process is supported by a team experienced in handling a wide range of materials, each with its own forming characteristics. Whether the project involves thin films, rigid laminates, or engineering grade polymers, the team ensures that washers maintain dimensional accuracy and surface quality throughout production.
Customization Options for Performance and Appearance
Beyond material selection, New Process Fibre offers customization options that help engineers tailor washers to their assembly needs. Washers can be produced in English or metric units, and Pressure Sensitive Adhesive (PSA) can be applied when assemblies require simplified installation or temporary positioning.
Color options include red, green, blue, yellow, black, orange, and white, with color matching available for select materials. These choices support branding, visual identification, and assembly organization in industries where color coding is part of the workflow.
