Blasting machines

Blasting systems from MHG have been setting standards for nearly 40 years. Innovative technology, stable, high-quality processing and a design that is well-thought out down to the last detail guarantee first-class surface results, the highest operational safety and energy-saving, environmentally-friendly function.

Whether blasting for cleaning, deburring, lapping, production, refinement or the finest blasting of highly sensitive workpieces, the extensive MHG standard machine programme offers powerful solutions for every area of application, providing impressive returns in durability, efficiency and investment security. The same applies for our service department, which reliably supports you from the planning to the timely installation and beyond. And that comes with the best recommendations: numerous references from renowned companies both domestically and internationally.

MHG blasting systems save on operating costs without compromising quality. This is assured by the energy-efficient technology, lighting units with energy-saving lamps and the MHG energy-saving system, which automatically switches off the extraction fan and lighting when the blast cabinet is not in use. Just a press of the foot pedal is enough to reactivate the blasting process without having to switch on the blast cabinet manually.

Additional safety is provided by electrical safety cut-offs, which, corresponding to the latest regulations for safety in the workplace, automatically interrupt the blasting process as soon as the cabinet doors are opened. The special design of the MHG blasting systems, with large viewing panes and lateral doors that seal tightly even after years of use, enables safe handling of the workpieces and precise, dust-free blasting. Special air intake ducts above the viewing window additionally improve the view while blasting. The effective sound insulation of the blast cabinet also helps to noticeably reduce the noise level at the workplace.

Finally, the innovative MHG blast medium reclaim system guarantees low consumption and, at the same time, a constantly high quality of the blast medium. In this manner, efficiency and outstanding blasting results are optimally combined. Clean matter: energy-saving, safe, resource-saving.

Not only years of experience are the basis of the design of our blast machines, but also the research in our in-house test center. Through test series and beam tests, we develop our standard systems, but also special designs according to customer requirements. Whether in aircraft construction, the automotive industry, medical technology or glass design: Our blasting systems are up to the most varied challenges.

Of course, we also offer the service for our systems: Advice, maintenance and care are provided by our competent team of technicians so that you can always rely on your sandblasting machine from MHG.
 

The blasting system consists of the elements blast cabin, recovery system and an exhaust air filter. The noise insulation of the MHG sandblasting machines enables working at a low volume. The recovery system allows economical use of blast media, since already existing material can be reused. The exhaust air filter ensures dedusting of the workpiece surface and can be used with different filter material.

The functions of the three-component blasting system can be divided into grinding, aspiration, removal, separation, recovery and finally reuse of the operational blasting agents. Thus, tasks such as cleaning, matting, deburring, descaling, paint stripping and roughening of a variety of surfaces can be done in a time-saving and cost-effective manner.

Depending on the workpiece surface to be machined, the three-component blasting system can be used in hand blasting cabinets or in fully automatic sand blasting systems. The two blast processes of injector blasting and pressure blasting are supported in order to achieve a suitable abrasive effect for an optimal result.

The blasting media which can be used include plastic resins, glass beads, glass breakage, corundum, mixed corundum, normal corundum, shell granules, cast steel or chilled cast iron, and ceramics. The use of quartz sand is prohibited in Germany in dry blasting systems because of the risk of silicosis (also known as silicosis).

Our blasting units are used everywhere where surfaces are to be processed or cleaned. Individual components may be blasted by blasting machines e.g. be deburred, a paint stripping or a surface compaction. This usually happens in stationary systems. MHG GmbH offers blasting systems in a three-component system: The individual system consists of a vacuum booth in which the material is processed.

With a jet nozzle, or the blasting gun you can work very exact when needed. The negative pressure is created by the extraction system, which transports both the abrasive and the residues to the recovery system. Here both elements are separated. The recovered blasting agent is returned to the blasting process.

The MHG free jet systems consist of a blasting agent bowl on rollers, a metering valve, nozzle, remote control, breathing air hose and filter as well as the protective clothing. With this mobile device it is possible to clean surfaces everywhere, to remove a coating or to eliminate traces of corrosion.

In the processing of individual large workpieces these free jet systems are used as well as e.g. in building technology. On request, we also manufacture these blasting units in an individual customer design.
