Leaders in electrical discharge machining (EDM)

Posted by IndustryNet on Wednesday, October 24, 2018

100000289Small_hole_drilling_EDM_machinesElectrical discharge machining (EDM) is sometimes known as die sinking, wire erosion, burning, spark eroding, spark machining or wire burning.

This process of shaping materials via the use of sparks or electrical discharges is a key part of the precision machining industry due to the precise nature of the components produced. 

Positioning EDM in the industry

To better understand what the top EDM companies contribute to the field, you must first have a feel for this sector. There are 137 companies in electrical discharge machinery and machining, accounting for 1,679 jobs.

The average current sales in EDM is $115.40 million. Of those companies, only three are women-owned and three are minority-owned. Nine of the companies import raw materials and 107 have domestic distribution with 127 offering international distribution.

To put those figures in perspective, consider that precision machining as a whole has 124,276 jobs with 7,638 companies and current average sales of $25.70 billion. As such, EDM accounts for 1.35% of the industry's jobs, 1.79% of companies, and 0.45% of its sales.

Those interested in the distribution of EDM companies across the country will find the largest number of them, 65 or 47%, in the Midwest. This is followed by the West with 29 or 21.17% of companies, the Northeast with 24 or 17.52% of companies, and finally the South with 19 or 14% of companies.

Industry growth trends

Those current figures do not exist in a vacuum and the EDM industry has experienced growth within the last year. Take the 1,679 current jobs, for example.

By comparison with the current figures, the sector had 1,614 jobs last year, indicating an increase of 4.03% over the past year. The increase in average sales from the previous year is similar at 3.78% based on $111.20 million average sales a year ago.

Top 10 companies by number of jobs

One of the most effective methods of determining the top companies in the world of electrical discharge machining is based on the number of jobs that they provide.
