Astro Manufacturing and Design strives to be at the forefront of advanced machining services. That's why we've invested heavily in EDM technology. In addition to our wire EDM services, Astro Manufacturing and Designalso offers precision sinker EDM services.

With sinker EDM technology, Astro Manufacturing and Design can manufacture parts of unimaginable complexity—even with the most rigid materials. Astro Manufacturing and Design's CNC sinker EDM machines enable us to machine complex profiles into a surface, or add threads within a fully hardened part.

We employ a wide assortment of sinker EDM machines to cover a range of close tolerance parts, from very small components to those requiring working areas as large as 19” x 16” x 11.5” high.

Our skilled sinker EDM machinists and engineers have the training and experience to offer design suggestions that will help ensure you receive the most cost effective sinker EDM parts. This combination of talent and technology allows Astro Manufacturing and Design to provide some of the fastest, most accurate sinker EDM machining services available.
