What Engelbert Sellmaier Feinwerktechnik does

Engelbert Sellmaier Feinwerktechnik GmbH is a privately held German precision engineering manufacturer based in Bischofswiesen, Berchtesgadener Land, operating from two production halls totaling approximately 2,500 sqm with roughly 80-100 employees. The company produces miniaturized fine-mechanical components and assemblies across six core product lines: measuring movements and pointer mechanisms (over 2,000 variants for pressure, vacuum, temperature, humidity, flow, content, and torque measurement); mechanical assembly groups; small gears for medical, robotics, and automotive applications; CNC automatic turned parts on Swiss-type lathes (1-14 mm diameter); stamping and bending parts (0.05-3.00 mm thickness, up to 60 tonnes cutting pressure); and gear cutting parts (1.5-64 mm diameter, modules 0.15-1.0, accuracies ≤0.005 mm) using gear cutting machines originally developed for the Swiss watchmaking industry.

The business model is custom B2B contract manufacturing with quote-based pricing and direct sales from the headquarters. Production runs focus on small to medium series, with customers concentrated in Germany, Austria, and the Salzburg region, while international sales in more than 40 countries are channeled through the wholly-owned export subsidiary Bachmaier & Klemmer GmbH (acquired January 2007). The company maintains EN ISO 9001:2015 certification (held continuously since 1996), a DIN EN 16247-1 energy audit, and German production throughout. Ownership and management are concentrated in founder Engelbert Sellmaier as sole managing director, with no external investors or capital raises disclosed.

Brands

• Bachmaier & Klemmer: Export customer acquired in 2007, now operating as Bachmaier & Klemmer GmbH

Products and services

• Messwerke und Zeigerwerke (Measuring and Pointer Movements) High-precision fine mechanical measuring movements and pointer mechanisms for analog display instruments used in pressure gauges, thermometers, diaphragm pressure gauges, membrane gauges, capsule gauges, and flow/level measuring devices. Used by manufacturers of analog measurement and control instruments.
• Baugruppen (Mechanical Assembly Groups) Fine mechanical assemblies combining individual precision engineering components into complete systems, developed according to customer specifications or in-house joint developments, including final inspection per test plan. Used by industrial OEMs requiring complete subassemblies rather than individual parts.
• Kleingetriebe (Small Gears) Complete small gears manufactured to customer specifications, including punched parts and gear cutting parts assembled into complete fine mechanical assembly groups. Targets OEMs in medical engineering, robotics, model construction, and automotive engineering requiring miniaturization.
• Automatendrehteile (Automatic Turning Parts) Precision turned parts manufactured on CNC Swiss-type automatic lathes and automatic ring lathes (ESCO), with diameters from 2 to 14 mm. Post-processing options include punching, bending, drilling, threading, reaming, countersinking, and rolling. Used by industrial customers requiring turned precision components.
• Stanz-/Biegeteile (Stamping/Bending Parts) Precision engineering components produced in a modern stamping shop, including punched parts, bending parts, and formed parts. Material thickness processed from 0.05 to 3.00 mm with cutting pressure up to 60 tonnes; in-house tool making for cutting, bending, and progressive die tools. Used by industrial OEMs needing fine sheet metal components.
• Verzahnungsteile (Gear Cutting Parts) Precision gear cutting parts including straight-cut gears, gear segments, pinions, involute splines, pulleys, and axles with diameters from 1.5 mm to 64 mm and modules from 0.15 to 1.0. Manufactured using gear cutting machines from the Swiss watchmaking industry, achieving accuracies ≤0.005 mm; also available in plastic (injection moulding) and hybrid metal/plastic combinations. Used by OEMs producing small gears and gear assemblies.
