Rosler Metal Finishing has worked in the forge and foundry industries for decades. With more than 80 years of experience, we have developed sophisticated shot blasting systems for countless work pieces including forgings, non-sand castings, and powdered metal components.
Our Forge & Foundry Blog Series continues with an overview of our shot blasting machines most frequently used on these specific types of work pieces.
It is important to understand your work piece and process requirements including whether components will be processed continuously or in batches. When it comes to finishing forgings, non-sand castings, and powdered metal components, our shot blasting machines are divided into three categories based on how the work pieces are fed into the machine: continuous, batch, and specially engineered shot blasting machines.
Continuous Shot Blasting Machines
RMBD Continuous Tumble Belt Machine
The high-capacity, continuous feed RMBD is available in a heavy-duty version for large forgings and castings, which is equipped with 6 x 40 HP turbines, a steel-slatted work piece transport belt, and a magnetic separator.
Ideal Work Pieces — Large volumes of small- to mid-sized work pieces such as connecting rods, transverse car links, parts for automatic transmissions, locking systems, brake pads, oil pans, cylinder head covers
RHBD Continuous Spinner Hanger Machine
With an overhead monorail trolley transport system, the RHBD is capable of processing single, large, and heavy work pieces in continuous feed mode while batches of small- to mid-sized work pieces can be placed on a special work piece fixture shaped like a Christmas tree. The special foundry version features extra wear-proof lining in the blast chamber and a magnetic separator.
Ideal Work Pieces — Forged levers, crankshafts, impellers, large pistons
RDGE Continuous Wire Mesh Belt Machine
Work pieces pass through the shot blast area on a wire mesh belt, never touching each other during the shot blast process within the RDGE.
Ideal Work Pieces — Delicate mid-sized components such as chassis frame components for cars, housings, all kinds of gears, door pillars for passenger cars
Batch Shot Blasting Machines
RMT Multi-Tumbler Batch Shot Machine
The RMT’s specially shaped rotary drum optimizes work piece mixing.
Ideal Work Pieces — Very small to mid-sized, sturdy components such as bushings, fittings, small shafts, chain links, levers
RMBC Batch Tumble Belt Blast Machine
The heart of the RMBC batch machine is an endless belt made from rubber or steel slats forming a trough. Work pieces tumble intensively within the trough.
Ideal Work Pieces — Relatively small and mid-sized, sturdy components including cast turbine blades, all kinds of fittings, small pump housings, shafts, small gears, springs
RHBE Batch Spinner Hanger Machine
An electric trolley running on an overhead rail, usually in the shape of a Y, drives the work pieces in and out of the RHBE shot blast machine.
Ideal Work Pieces — Mid-sized to very large and heavy work pieces weighing up to 15 tons including very large crankshafts, gears
RDT Rotary Table Machine
Single, large components or small batches of smaller work pieces are placed on a rotary table within the RDT and blasted from above.
Ideal Work Pieces — Mid-sized to large, heavy components; frequently used for cleaning of forgings and other molds
RWK Turning Chamber Machine
The RWK is equipped with a circular chamber divided into two 180° sections with one section in the blast chamber and the other section at the load/unload station. After each cycle the chamber rotates 180° to allow for simultaneous loading/unloading and processing.
Ideal Work Pieces — Circular and semi-circular parts up to 48 in high such as drive shafts, bevel gear components, automotive wheels
RWT Turning Table Machine
Much like the RWK, the RWT includes a circular chamber divided into two 180° sections with one section in the blast chamber and the other section at the load/unload station. After each cycle the chamber rotates 180° to allow for simultaneous loading/unloading and processing. Differing from the RWK, the RWT is better suited for smaller, delicate work pieces.
Ideal Work Pieces — Circular and semi-circular parts including sprockets, small drive shafts, small pistons, fuel pump wheels
Specially Engineered Shot Blasting Machine
RKWS Crankshaft Shot Blast Machine
Designed to blast clean various sizes of crankshafts, the RKWS features a carousel divided into three or four chambers to create multiple blast chambers and one load/unload station. Fully automatic operation is enabled with the use of robotic work piece handling.
Ideal Work Pieces — Crankshafts in lengths of 12-28 in and weights of 14-55 lbs
