The mobile workstation for manual material application

The SONDERHOFF DM 70 COMPACT is a low-pressure mixing and dosing machine for the processing of one or two components in manual operation for sealing, bonding and potting. This machine precisely processes and doses liquid, medium and high viscosity compounds such as polyurethanes, silicones, epoxy resins or other polymeric reactive materials.

Simple processing

The SONDERHOFF DM 70 COMPACT is designed in such a way that you as an operator can easily and safely fulfil the most divers tasks. The operation is carried out with a 7’’ touch screen. The SONDERHOFF DM 70 COMPACT is based on a non-recirculating system with continuous material dosing by means of precision gear pumps. The processed materials are mixed by a static mixing head (SONDERHOFF MK 20) or a dynamic mixing head (SONDERHOFF MK 50). All machine components are housed on a mobile chassis. The easy access to the machine allows fast and comfortable completion of service and maintenance work.

Guaranteed quality

The mixing and dosing machine SONDERHOFF DM 70 COMPACT processes the used materials with constantly high production quality. The machine control allows the operator to store and monitor the main material-processing parameters, such as material reactivity data. In addition, parameters for automatic rinsing or automatic repeat shot dosing, and the gauging and shot time can be programmed, as well as the material feed quantity and mixing ratio can be set variably.

Flexible today, flexible tomorrow

The SONDERHOFF DM 70 COMPACT for the processing of one or two components permits the manual application of a wide range of materials by means of a handheld pistol, consisting of either the SONDERHOFF MK 20 or SONDERHOFF MK 50 mixing head. It is a mobile stand-alone system that can be used in your production in a space-saving manner. Functional design, proven technology and reliable processes guarantee the profitability of your investment.
