About Us


Electro Erosion Specialties, Inc.

Electro Erosion Specialties, Inc. (EESI) is a third-generation, family-run business originally located in south Seattle. In 1995, we moved our services south to the Renton/Kent valley and re-branded our shop and services. Over the years we have transitioned from selling and teaching Electrical Discharge Machining (EDM) to becoming a fully-equipped Tool and Die shop.
At EESI, we provide more than just EDM. We provide a wide array of services and machining capabilities that keep the process of your job mostly in-house. We can take your part or job from concept all the way through creation to final product. 
At EESI, we strive to keep up with the latest technology and machining practices. Our team is trained in many different software systems, from those that can design and make solids to others that perform complex machine algorithms to create a one-of-a-kind program for your part. Our highly-skilled employees can take a file and turn it into a reality using our wide range of machining capabilities.
All this, in most cases, can be done without leaving our shop floor. This greatly reduces the risk of parts getting lost or of experiencing miscommunications, extended lead times, or a part being scrapped by a supplier.
