Wire EDM Specialists

With over 60 years of combined experience, we've learned you want a job shop that can handle BIG jobs in LESS time - without sacrificing quality or customer service

 Trumont Supply offer's service's on one of the largest wire EDM machines in the American Midwest, that is uniquely positioned to handle some of the most challenging EDM wire work in the market.

In this instance, our plastics industry client required a 30" X 50" size mold that would produce a high-pressure, plastic container. We were able to accommodate that large part by using electrical discharge machining on our over-size EDM machine which has the ability to cut a 50" X 36" X 20" fully submerged part. Our precision, high-tech Makino U86 wire EDM machine cut eight lifter pockets through various parts of the block. Those pockets sides were parallel to each other but not square to the block and were positioned 10° from the vertical.
Trumont Supply offers its EDM services and experience to maximize quality and significantly reduce job costs to the benefit of its customers whenever possible.
On this cylinder mold, we achieved extremely tight tolerances of -.0000/+.0002 and performed in-process testing and inspections. We also verified to +.0001 using certified gage blocks.
Our round-the-clock service ensures the type of rapid turnaround that allowed us to produce this single unit in P-20 alloy steel in just two days.

Our goal is to exceed your expectations with value, quality and on-time delivery.
We will accomplish this by communicating with you from the start of the job to its completion and will share our thoughts on job strategy to provide you additional savings. Let us show you what real customer satisfaction is all about. Trumont Supply has served the stamping, plastic injection mold, die-casting and precision machining industries throughout its existence along with many others in and around northern Illinois.
