Operations  are adjusted for workload.  Typical shift run based on 8-10Hrs/day, with an available second shift if workload requires. We  also manufacture multiple components in lights out manufacturing processes (6 Axis Robot feeding  a 5 Axis Mill, or Bar Feeders on Multi-Axis CNC Machines, capable of running 24hr/7day).

Protomatic specializes in hard-to-manufacture small and medium sized precision components for R&D, medical, aerospace and other technical industries.  We support build quantities from prototype to production.

Protomatic is a Solidworks (CAE), Surfcam (CAM), and GibbsCam (CAM) user. This gives us the ability to read almost every industry standard format. If possible, native Solidworks is best, but alternately STeP, Parasolid, IGeS, or DXF can be read. For secure documents encryption please call, and formats may include Adobe PDF, Myriad or ImageR are readable.

Protomatic enlists the services of approximately 25 employees as of 2024,  and the building currently covers 30,500 square feet on two floors.  Over 30 programmable CNC style machines, such as CNC Mills, Lathes, robot, vision system, and CMMs.

Protomatic has the capability to produce many types of Inspection Sample Warrants (SW) for a majority of industries such as aerospace, automotive, medical, and electronic industries. (PFEMA, PPAP, Control Plan, GP-11, FAI, ISW, AS9102, Custom Reports utilizing sampling plans from 100%, Mil-Std-105, Mil-Std-1916 C=0, and ANSI/ASQ Z1.4.)

Protomatic is more vertically integrated for custom and specialized processes than most job shops. We employ many specialized process (Non-NADCAP) such as; programmable polishing equipment, micro deburring, virgin tumbling for medical class A surfaces, CO2 cleaning, rubber molding (vulcanized and two part castings), adhesive bonding, laser marking, and rivet assembly. Ask Sales for the process list for details.

Protomatic is continually working on compliance of NIST SP800-171 standard.
