Forge & Foundry, Part 9 – Frequently Used Shot Blasting Machines for Forgings, Non-Sand Castings, and Powdered Metal Components

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 — 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.
