Membership in the Precision Machined Products Association (PMPA), an international trade association that represents the precision-machined products industry and provides members with technical resources, benchmarking data, advocacy, and networking to support sustainable success in precision machining operations.:contentReference[oaicite:0]{index=0}

Precision Machined Products Association (PMPA) Membership

Involves the fabrication and assembly of electronic components, semiconductor devices, printed circuit boards, and advanced microelectronics, as well as the manufacture of supporting mechanical components such as casings, enclosures, and structural parts. Cleanroom processes, ESD controls, precision machining, and adherence to industry standards (e.g., IPC, JEDEC) are critical for achieving high-density, high-performance products in mass-market, specialized, and ancillary applications.

Electronics & Semiconductors

Produces ultra-precision Swiss-turned standoffs, connector pins, and RF shields used in high-density PCB assemblies and semiconductor test fixtures.

The design, manufacturing, and assembly of components and systems for passenger cars, commercial and off-highway vehicles, rail rolling stock, and emerging electric/Autonomous mobility platforms. High-volume production, IATF 16949 compliance, JIT supply chains, and continuous innovation ensure reliable powertrains, safety-critical systems, and cost-efficient delivery across a broad transportation landscape.

Automotive & Transportation

Manufactures precision fuel-system metering sleeves, throttle shafts, and sensor housings for recreational and specialty automotive platforms.

The design, fabrication, and assembly of diverse products across multiple end‐use industries or specialized, project‐based needs. Emphasis is on versatility, custom solutions, and broad expertise to handle unique or varied manufacturing projects outside of more narrowly defined sectors.

General Manufacturing

Supplies custom Swiss-turned pins, bushings, and miniature valve components for diverse OEMs requiring repeatable ±0.0005 in tolerances across low- to mid-volume programs.

The design, manufacturing, and integration of high‐precision components, systems, and subsystems for commercial aircraft and military platforms, with emphasis on meeting stringent certifications such as AS9100, ITAR, and MIL‐STD. Priorities include advanced materials, rigorous quality assurance, and robust engineering to ensure reliability in mission‐critical applications.

Aerospace & Defense

Swiss-turned fuel-system pins, sensor housings, and firing-pin sleeves for small-caliber applications, meeting DFARS and customer AS9100 flow-downs.

The development, manufacturing, and supply of precision-engineered medical systems, devices, and critical components, including diagnostic equipment, surgical instruments, implantable devices, laboratory systems, and precision medical components. Emphasizes adherence to ISO 13485 and FDA QSR standards, traceability requirements, sterile processing, rigorous validation, and use of biocompatible materials such as titanium, stainless steel, and medical-grade polymers to ensure patient safety and clinical effectiveness across global healthcare settings.

Medical Devices & Healthcare Equipment

Machines micro-diameter surgical pins, catheter contacts, and biomedical fasteners from 17-4PH stainless and PEEK for single-use and reusable medical devices.

Design and manufacturing of precision instrumentation and analytical equipment utilized in laboratory, industrial, research, and testing environments. These instruments typically include spectrometers, chromatographs, microscopes, analytical sensors, and lab automation systems, built to strict accuracy standards and compliance requirements (ISO, ASTM, FDA, or equivalent).

Scientific Instrumentation & Analytical Equipment

Provides precision connector pins and miniature valve components for scientific analytical instruments requiring leak-free gas control and sub-micron repeatability.

Founded in 1973, Hannes Precision Industry, Inc. is a family-run contract manufacturer that machines ultra-tight-tolerance Swiss components for electronics, automotive, defense, medical, and scientific-instrument markets. Two Norwalk, CT plants house eight Tornos DECO CNC Swiss lathes, Hardinge secondary lathes, Agathon/Hoffmann grinders, and a Serec vapor degreaser. ISO 9001:2015 certified, the shop applies in-process SPC and automated optical inspection to hold ±0.0005 in. Materials processed include stainless steels, brass, beryllium copper, aluminum, tool steels, and engineering plastics. Lead times run 1 week to 26 weeks, and a stock-for-rush policy ships same-day on repeat parts.

Administrative and engineering headquarters occupying office space adjacent to production on Pleasant Street. Houses sales, estimating, quality engineering, and final-inspection labs in a climate-controlled environment. Downtown East Norwalk location sits two minutes from I-95 and South Norwalk freight rail, enabling same-day customer visits and rapid parcel shipments across the Northeast.

Corporate Office

Primary production plant on Fort Point Street containing eight Tornos DECO CNC Swiss lathes with automated bar feeders, Hardinge secondary lathes for cross-drilling and slotting, Agathon and Hoffmann grinders, and a Serec vapor degreaser. The cell layout supports lean, one-piece flow and in-process SPC. Shipping docks 0.5 mi from CT-136 and Norwalk Harbor enable efficient inbound steel and same-day LTL to Northeast hubs.

Production Plant
