About the hetech group
The hetech group is a full-solution provider for particle foam and paper fiber technology (molded pulp). The company was formed in 2025 from the merger of HIRSCH Technology/HIRSCH Maschinenbau and Erlenbach Maschinen and belongs to the HIRSCH Servo Group. It manufactures and supplies pre-expanders (vacuum, fluidized bed, high-pressure, IR), shape and block molding systems, cutting and recycling systems, aluminum molds for EPS, EPP and paper fiber, as well as silo, loading and peripheral systems through to turnkey complete systems. The value chain ranges from consulting, engineering and mold making to testing, installation and commissioning, through to maintenance, retrofit and global service. Industries served include packaging, construction/insulation materials, automotive, HVAC, technical applications and recycling. Competence centers are located in Lautert (Germany), Seeboden and Glanegg (Austria), Petrovany (Slovakia) and Grosuplje (Slovenia); the sales office is in Abstatt.
