About

Back in 1927, F. Carl Porter founded New Process Fibre (NPF) with a desire to improve manufacturing processes; Porter coined the company name after the innovative process he developed for a new, lower-cost means of turning cotton paper into vulcanized fibre.

Innovative Roots

Under the guidance of Porter’s son-in-law Henry Peters, NPF broadened its focus to improving every part of the the non-metallic stamping process, including vulcanized fiber washers.

Over the years, NPF has continued to grow and innovate — improving processes and providing essential non-metallic stamping solutions across a range of industries. Our family-run business is now in its third generation, and though our products and processes have changed since 1927, our family’s desire to constantly improve operations has never wavered.

An Overview of New Process Fibre

Solid Growth

Today, we continue the tradition of improving products, maximizing quality, and maintaining cost-effectiveness with our dedication to in-house manufacturing capabilities. We pride ourselves on keeping all operations in-house to ensure every step of the non-metallic stamping process is performed to the highest standard and we are consistently delivering the highest-quality products to our customers.

Some of our onsite capabilities include:

  • The extrusion of our own thermoplastics
  • An in-house tool room with wire EDM capability that allows us to create our own tooling
  • An extensive inventory of production equipment that makes it possible to complete virtually any job, from a small prototype run to a multi-million piece order

With all of these features available within our own facility, we can fill any order without the need for outsourcing.

Diverse Material Selection

At NPF, we stamp a wide variety of non-metallic materials in a large selection of colors. Some of the most popular materials in our diverse collection include:

  • Vulcanized Fibre: A laminated plastic comprised of natural cellulose, vulcanized fibre is a tough, resilient material that is lighter than aluminum, tougher than leather, and stiffer than most thermoplastics.
  • Acetal: A synthetic sheeting material, acetal copolymer exhibits high strength and resistance to impact and fatigue, making it a common weight-saving replacement for metal.
  • Nylon: Nylons are tough thermoplastics with a high capacity to withstand impact, wrinkling, tension, and bending in a wide range of temperatures –– from freezing to 300° F. In addition, nylons have low-friction properties, high electrical resistivity, and a strong resistance to alkalis and acids.
  • Nylon MDS: Nylons filled with MDS (molybdenum disulfide) are highly resistant to wear and exhibit physical properties about 20% greater than those of unfilled nylons.
  • High-Density Polyethylene (HDPE): HDPE is a corrosion-resistant material that has high-impact strength and can withstand extreme temperatures. The material also has high tensile strength and can resist abrasion and stress-cracking. With so many desirable qualities, HDPE is a popular material used in industries, such as food processing, chemical and petroleum manufacturing, and pharmaceutical processing.
  • Low-Density Polyethylene (LDPE): LDPE is a corrosion-resistant material made of highly branched polyethylene shaped through a die at very high pressures. LDPE has a soft surface, low moisture permeability, and good tensile strength, as well as useful electric properties. Often utilized in films and packaging materials, LDPE is commonly employed in the food processing, paper, chemical, petroleum, pharmaceutical, marine, and tanning industries.
  • Other Special Stamping Materials: NPF offers a wide variety of other special non-metallic stamping materials, such as Buckfab, Duroid®, Garlock®, Kraftpaper, and many more. If we don’t carry a certain material that you’re looking for, we are happy to work with you to bring in a special supply of it or find an acceptable replacement material. Check out our Special Stamping Materials page to see our offerings.

State-of-the-Art Tooling

NPF’s state-of-the-art tooling ensures we can accommodate a wide variety of designs and features to suit our customers’ diverse needs. With our large selection of more than 75 conventional and high-speed punch presses, over 10,000 compound washer dies, and a massive material inventory, we can create custom tooling for your non-metallic stamped parts. Our state-of-the-art tooling includes:

  • Free maintenance of your tool part design for the life of your program with a partial tooling charge
  • CAD/CAM and wire EDM capabilities
  • Custom die creations
  • Compound and progressive dies
  • Multi-cavity tools designed to save on material costs and improve throughput
  • Economical and critical tolerance tooling applications

In addition to our state-of-the-art tooling, we produce a number of extruded materials in-house, such as high-density and low-density polyethylenes, polypropylene copolymers and homepolymers, acetal copolymers, nylons, and nylon MDS. By manufacturing these materials in-house, we have more control over the materials used in stamping, adding value and quality for our customers.

A Dedication to Quality

Since 1927, we’ve been committed to delivering the highest-quality products to our customers. As part of our ongoing dedication to quality assurance, NPF constantly reviews and updates all of our systems and processes to ensure we’re meeting the highest standards. Some of our quality assurance practices include:

  • The use of hard tooling, developed in our own tool shop, for higher tolerances in production
  • The use of cutting-edge non-contact vision measurements with calibrations sourced from the National Institute of Standards and Technology
  • The implementation of a quality management system, registered with the International Organization for Standardization since 2002, with extensive documentation
