Precinmac is a diversified precision manufacturing group supplying complex, high-tolerance components and assemblies for aerospace, defense, semiconductor, and nuclear sectors. Founded in 1974, the company operates through eight specialized portfolio brands - including Hoppe, HPG, Major Tool & Machine, MMPCO, Petersen Inc., Shields, Trimaster, and Viper Northwest - across eight locations in the United States and Canada.
The group combines precision machining, fabrication, engineering, and program management under a single-source model. All facilities hold ISO 9001:2015 and AS9100D certifications. Precinmac brings over 150 years of combined engineering experience to component design and manufacturing, operating on lean manufacturing principles with emphasis on quality assurance and on-time delivery.
For organizations handling sensitive supply chains in defense, aerospace, and semiconductor equipment manufacturing, Precinmac's infrastructure supports the precision requirements and traceability demands those verticals impose. The consolidation of specialized capabilities - from concept through completion - reduces vendor complexity for programs requiring high-tolerance assemblies with documented quality pedigree.
