Revenue model
- Welding Equipment and Machinery Sales: HERZ generates revenue primarily from the manufacture and sale of plastic welding machines, hot air welding devices, extrusion welders, heating and bending machines, and related accessories. The company sells a comprehensive product catalog including roof welding machines, apparatus and tank construction equipment, extruders, air heaters, blowers, and ignitors. Products are available for purchase directly, with options to customize specifications to customer requirements.
- Equipment Rental Program: The HERZ rental program (HERZ Mietprogramm) offers short-term rental of plastic welding equipment including welding automatons, extruders, and mirror welding devices. This provides flexible access without long-term commitment, enabling customers to test equipment for specific projects or short-term specialized work. Pricing is 'fair' and equipment is of 'best quality.'
- Custom Product Development and Manufacturing: HERZ develops and manufactures products to customer specifications ('auch Produkte nach Ihren Vorgaben - vom Schweißsystem bis hin zum Lufterhitzer'), providing custom-engineered solutions for specialized industrial applications in addition to standard catalog products.
