What Witosa does
Witosa GmbH is a privately held, family-owned German engineering company founded in 2005 and headquartered in Frankenberg-Wangershausen, Hesse. The company is owned and led by brothers Torsten and Willi Glittenberg as managing directors. It specializes in hot runner systems and hot runner technology for plastic injection molding, serving moldmakers and plastics processors primarily in the DACH region with selected international reach into Switzerland and Brazil.
The company's defining technological bet is the systematic application of additive manufacturing (laser-powder bed fusion of metal powders) to hot runner components, which enables internal geometries — integrated isolation chambers, honeycomb insulation inserts, and converged cooling/ejection/gating channels — that conventional subtractive machining cannot produce. Its flagship MONOLITH® brand of additively manufactured hot runner nozzles, launched in 2021, is complemented by MONOLITH®FLAT for ultra-close nozzle pitches, MONOLITH®PLUS MULTI and MULTI-WELL for multi-cavity and gate-free well plate production, Energy BLOCKER® insulation inserts (claimed up to 52% energy reduction versus titanium inserts), needle shut-off drives installable in clamping plates as low as 47mm, and a three-tier R6/R7/R8 temperature controller family with OPC UA integration for Industry 4.0 environments. Products are sold engineered-to-order with project-specific thermal simulation and a free 24h Expressdaten preliminary CAD service.
Witosa runs a sales-led, consultative go-to-market combining direct enterprise sales, application engineering, trade fair presence (FAKUMA, Interplast), customer seminars at its technology center, and regional sales representatives (notably Casafer in Brazil). Revenue is generated primarily through engineered-to-order hardware sales of hot runner systems and components, supplemented by free pre-sale technical consultation, Moldflow simulation support, and an optional 3-year Full Service contract that includes free wear parts. Pricing is quote-based and not publicly disclosed. The company operates without external institutional investment or parent company and does not publish financial results.
