Our laser cutting services are highly effective, accurate, and cost-effective, benefitting many industries, including electronics, medical devices, military and aerospace, food and beverage processing, and agriculture.

Stamping

ESPE Manufacturing is a leader in producing stamped parts made from electrical insulation and barrier materials. We also forge components from non-metals, such as specialized composites, aramid papers, and other materials. In addition, we use various stamping methods, including compound die, progressive die, and punch press operations for our products — whether in small quantities or bulk production. Finally, we have thousands of washer die sets in stock that can help our customers save money by eliminating the need to build custom tooling.

Our stamping expertise allows us to work on the continuous strip and coil stock ranging in thickness from 0.005 in. to 0.25 in. Moreover, we have a large stamping unit with up to 40-ton presses for constructing small parts of any geometric structure. Using our tried-and-tested processes, we also maintain precise fabrication tolerances depending on the specifications.

ESPE Manufacturing offers the following production methods for our stamping services:

  • Coining
  • Compound die

Die Cutting

Die cutting is frequently the most cost-effective method for manufacturing high-quality electrical components, rubber products, and labels. At ESPE Manufacturing, we offer custom die cutting services for various applications in several industries — such as medical, automotive, aerospace, electronics, and military.

We also cut any shape of plastic and non-metal materials with thicknesses ranging from 0.003 in. to 0.062 in and employ a variety of electronic file formats to ensure extreme accuracy in our cutting tools. Our high-performance 60-ton hydraulic flatbed, punch, and steel rule die-cutting presses can handle any manufacturing capacity without compromising performance or quality.

Shearing and Slitting

ESPE Manufacturing offers precision shearing and slitting services, including razor, score, shear slitting, baloney cutting, crush cutting, and others. We can regulate blade sharpness, cutting pressures, roll tension, cutting speed, and other factors using computer controls to accomplish and keep quality cuts within very tight specified tolerances. We also process material up to 0.093 in. thick and provide rolls with diameters up to 36 in.

Nylon Machining and Fabricating

The combination of strength and durability has increased the use of nylon for commercial and industrial purposes. Manufacturers now use it to create machined parts that are more durable and long-lasting than available alternatives. As an added benefit, nylon’s thermal and chemical resistance and dielectric properties make it suitable for numerous industrial applications.

At ESPE Manufacturing, we deliver nylon machined components for washers, wear parts, seals, and gaskets.

Teflon Machining and Fabricating

Teflon® is a versatile material composed of highly specialized plastic with unique chemical and mechanical properties. Aside from non-stick kitchen cookware, it is now being used in many industrial applications due to its ability to resist corrosion and withstand extreme temperatures.

ESPE Manufacturing can fabricate the following parts using Teflon® machining:

  • Seals
  • Shoulder washers
  • Gaskets
  • Bushings
  • Electrical insulators
  • O-rings
  • Spacers

Custom Parts for Electrical Insulation and Barrier Materials

ESPE Manufacturing supports the following production volumes to meet our customers’ requirements:

Prototyping

During the prototyping phase, a few parts are manufactured for testing, resulting in cost savings by assessing issues or product defects before full production.

Low Volumes

Low-volume production usually includes trial runs from 50 to 100,000 parts and components. It also provides several benefits, including shorter lead times, reduced costs, and design flexibility.

High Volumes

High-volume production pertains to the rapid mass production of parts, usually with quantities ranging from more than 100,000 to millions. It also has several advantages, such as lower unit costs, quicker turnaround times, and economies of scale as volume increases.
