Sterling Machine Technologies

What Sterling Machine Technologies does

Sterling Machine Technologies, Inc. is a privately held precision machining and fabrication services company founded in 1987 by Randy Herr and headquartered in Palmyra, Pennsylvania. It operates from a single 20,000+ square foot facility (with a 3,500 sq ft weld building added in 2021) and employs 37 full-time workers. The company provides custom precision CNC machining, large-diameter and long turning/VTL services, and ASME/AWS-certified welding and fabrication to industrial manufacturers, government contractors, utilities, transportation providers, and equipment builders throughout Central Pennsylvania — including Harrisburg, Lancaster, York, Hershey, Lebanon, and Reading.

Its core technical capability is built around large-part machining: Mazak Integrex 5-axis machines, Doosan/DMG MORI horizontal and vertical machining centers, a Mazak E-650H with 36-inch turn diameter and 120-inch length capacity, a G&L vertical boring mill with a 67-inch table, and CMM/precision inspection equipment (Romer Arms, Brown & Sharp, LK Ultima 30.20.15). Quality is anchored by ISO-9001:2015 certification, ASME Section IX, and AWS D1.1/D1.6 welding certifications, enabling access to pressure vessel, structural, and regulated procurement work. Secondary services (delivery, hydro testing, sand blasting, primer application) are bundled to reduce customer vendor count.

Sterling operates a direct-to-customer professional services model with quote-based pricing (no public rates), customer acquisition via a local SEO service-area website, online quote form, and inbound phone contact. The company is family-led (Randy Herr as President/Estimator, Shairah Herr as VP, Gina Herr as business partner), bootstrapped with no external funding or institutional ownership, and reports self-stated objectives of 100% on-time delivery and 100% conforming parts. Geographic scope is regional; social media presence and digital channels beyond the company website are not evident.
