OTEC

What OTEC does

OTEC Präzisionsfinish GmbH is a privately held German manufacturer of precision surface finishing equipment, headquartered in Straubenhardt-Conweiler, Germany. Founded in 1996, the company employs 51-100 people and operates a global network of more than 40 sales representative offices. Its product portfolio is built around two technology platforms: Gleitschleifen (mass finishing), comprising centrifugal disc (CF series), drag (DF series), stream (SF series), and vibratory bowl machines; and Electrofinish (electrochemical polishing), offered across multiple EF series (EF-Performance, EF-Vario, EF-One, EF-Compact) with vertical-specific variants for dental, jewellery, and pharmaceutical applications. Supporting the platforms are separation systems, centrifuges, and a complete consumables line covering ceramic, zirconia, plastic, stainless steel, and dry-grinding media. All manufacturing is conducted in-house at the Straubenhardt facility, with 100% 'Made in Germany' positioning and an underlying supplier base of more than 430 German partners.

The business model combines four revenue streams: hardware sales of CF, DF, SF, and EF machines; recurring consumables from process media; contract processing services via the OTEC Finishing Services subsidiary (toll processing for customers without their own equipment); and aftermarket service, sample processing, and digital process simulation. Go-to-market is sales-led, combining direct enterprise sales from headquarters, a global dealer/distributor network, demonstration-driven lead generation through sample processing, and trade show presence (most recently AMB 2026). End markets include medical technology, dental, automotive, jewellery/watchmaking, aerospace, tooling, pharmaceutical, ceramic and plastic parts, food processing, and additive manufacturing, with GYSIN AG disclosed as a reference customer. R&D is anchored in long-standing research collaborations with Fraunhofer IPK and the WBK Institute of Production Science at the Karlsruhe Institute of Technology.

The company holds ISO 9001:2015, ISO 14001:2015, and AEO certifications and is led by Managing Directors Helmut Gegenheimer, Soran Jota, and Nico Gegenheimer. No external funding rounds, M&A activity, parent company, or public listing are evidenced in available materials, consistent with a founder/family-controlled, operationally profitable specialty industrial equipment business.

Core offering

OTEC develops, manufactures, and sells precision surface finishing machines and related process media for industrial component manufacturers. Its portfolio covers two technology platforms: mass finishing (Gleitschleifen) machines including centrifugal disc, drag, stream, and vibratory finishing systems, and electrochemical polishing (Electrofinish) equipment. The company also supplies abrasive consumables, separation/centrifuge equipment, and contract finishing services, with all hardware manufactured at its Straubenhardt, Germany headquarters.

Product overview

OTEC Präzisionsfinish GmbH is a German technology company and market leader in mass finishing and electrochemical surface treatment technologies. The product portfolio consists of two main technology platforms: Gleitschleifen (mass finishing / tumble finishing) and Electrofinish (electrochemical polishing), complemented by separation equipment, process media (abrasives), and finishing services. The Gleitschleifen platform includes CF-Serie (centrifugal disc finishing), DF-Serie (drag finishing), SF-Serie (stream finishing) in manual and automated variants, and Trogvibrator (vibratory bowls). The Electrofinish platform offers multiple series (EF-Performance, EF-Vario, EF-One, EF-Compact) with specialized variants for dental, jewellery, and pharmaceutical applications. Supporting equipment includes separation systems (FS-Serie, UNISEPA, magnetic separation, sieve separation) and centrifuges. OTEC also supplies comprehensive process media including ceramic, plastic, and stainless steel abrasives for wet processing, and plastic polishing bodies, dry granulates (corn, walnut) for dry processing. All products are manufactured exclusively in Germany at the Straubenhardt headquarters.
