Shot Blast Cleaning Systems – Various types of machines 08/06/20163  Air nozzle type  Tumblast with metal belt  Spinner Hanger  Overhead Conveyor  Hanger type  Polygonal Drum - Batch Type  Roller conveyor  Manipulator type  Throughfeed Blast Cleaning Systems  Shot Peening

Manipulator Type Shot Blast Systems 08/06/20164 Manipulator-type shot blast systems are known for their high performance and capability of cleaning castings of different sizes and configuration without a need of complicated tooling changes. This provides increased flexibility for changing production requirements in the cleaning shop.

Castings processed 08/06/20165

Manipulator Type Shot Blast Systems 08/06/20166 Blast cleaning and deburring of: Gear housings Cylinder blocks Cylinder heads Crankshafts Intake manifolds other serial parts in cast iron or aluminium (sand, gravity and pressure die-cast )

Manipulator Type Shot Blast Systems 08/06/20167 In-line solutions for automatic castings fettling lines Fully automatic sequence of operations including loading / unloading Easy integration, high production capacity Extensive range of machines offers high layout flexibility and allows “tailor- made solutions” adapted to customer needs Broad experience, numerous applications and outstanding references

Manipulator Type Shot Blast Systems 08/06/20168 Blast cleaning of castings of different shape and size without retooling Cleaning capacity: parts per hour depending on system used Loading capacity per manipulator: kg Cleaning of castings in pairs allows highest performance rates Workpiece scanning systems to control blast parameters (blast time, number of activated blast wheels, abrasive removal)

Manipulator Type Shot Blast Systems 08/06/20169 Castings rotate in the centre of the mani- pulator axis which ensures an optimum part-position under the blast stream Thorough cleaning of parts and internal passages Programmable cleaning of critical areas Combined manipulator motions (rotating, swinging, stopping) to expose critical areas to the blast stream Abrasive removal inside the machine and within operating cycle

Manipulator Type Shot Blast Systems 08/06/ The manipulator arms are able to seize one big or two small castings, even if they are of different heigth. The flexibility of the system allows to clamp motorblocks, cylinder heads, gear housings and many other castings DV 2DS 1

Throughfeed Blast Cleaning Systems 08/06/ Fully automatic and flexible blast cleaning of tumble-proof parts

Throughfeed Blast Cleaning Systems 08/06/ Throughfeed blast cleaning offers a number of advantages to ensure efficient and cost effective treatment of castings and forgings. The DT is equipped with a polygon-shaped trough, the blast wheel are positioned in a longitudinal axis above the flow of parts

Throughfeed Blast Cleaning Systems 08/06/ Removing sand and cores from castings Descaling castings and forgings Handling mixed and single product runs Cleaning clusters Continuous blast cleaning of tumble-proof parts Optimum utilization of abrasive energy Complete and gentle tumbling of parts No moving components in blasting area Easy integration into existing lines

Throughfeed Blast Cleaning Systems 08/06/  Fully automatic operation  Distribution of the castings over a relatively long blast cleaning zone  Blast wheels directly above the parts  Controlled throughput of castings  High capacity up to 35 t/h of parts up to 150 kg each  Low wear, maintenance friendly design

Throughfeed Blast Cleaning Systems 08/06/ Mode of operation The polygon shaped trough causes a gentle tumbling action. The high power abrasive streams aimed at the castings from above reach and thoroughly clean all surfaces and interior passages
