While working for a stamping company, Jack saw that the need for prototyping was becoming more of an issue every day. No one was satisfied. Customers never got parts to print, and in-house people hated doing custom parts. A magazine article in 1989 describing the capabilities of the Baltec CNC-Controlled hydraulic punch press became the foundation of what is today – Prototype and Short-Run Services, Inc.

The Baltec allowed disc drive, medical, electronic, aerospace, and even other large stamping companies to get small quantities of ultra-precision parts for testing before committing to large, expensive tooling. Since then, customers have driven the company into many new areas including more massive production runs of specialty parts and lately precision Wire EDM parts from eight brand new Mitsubishis.
