Electrical Insulating Materials for Custom Manufacturing
Electrical insulation parts are made from a variety of materials with different physical, mechanical, and chemical properties. Since all insulators are not the same, it is important to consider strength, flexibility, cost, and compliance with relevant codes when choosing the best electrical insulator for your application. Electrical insulating materials used in the fabrication process should have the following properties:
- Good mechanical strength
- Excellent dielectric strength
- Superior resistivity to prevent the flow or leakage of electricity
- Non-absorbent and free from impurities
- Wide temperature range to avoid impacts of sudden temperature changes
ESPE Manufacturing is an industry-leading specialist with extensive knowledge of flame-retardant, electrically insulating materials. We’ll assist in selecting materials that will provide superior shielding and thermal protection for industrial and consumer electronics.
The primary materials we work with include ITW Formex®, Nomex®, and fishpaper/vulcanized fiber. We also work with many other grades and types of plastics and papers.

Fabrication Methods
We use a variety of custom plastic fabrication methods to produce items. No specification is too complex for our production team. We’re one of the most experienced and proven companies in the field of laser cutting, die cutting, and digital cutting of plastics for electrical insulation parts. With our fleet of hydraulic presses, we can stamp items to exacting tolerances. Our custom plastic fabrication capabilities also include CNC turning and milling, as well as shearing and slitting.
At ESPE Manufacturing Co., Inc., we can accommodate a variety of production volumes to best fit your needs:
- Prototyping : Prototyping is an essential step in most design and development processes. In the prototyping phase, an extremely low volume of parts is produced for real-world testing, ultimately saving time and money by identifying functionality issues or design flaws in advance of full production.
- Low volumes : Low-volume production typically involves runs ranging from 50-100,000 parts. Low-volume production offers several advantages including, cost-savings, faster time to the market, and design flexibility.
- High volumes : High-volume production refers to the mass production of products over short time periods, with volumes ranging from more than 100,000 to millions. Some advantages of high-volume production include a lower cost per unit, faster turnaround times, and economies of scale as volumes increase.
