When a casting is produced, by-products are
generated. Small pieces originating from spills, gates, runners, and risers are
returned to the casting process as recycling material. To ensure a consistently
high overall quality of the raw material, it is essential that this recycling
material is perfectly clean without any sand, casting shell, or other residues
on the surface.
Subjecting these by-products to a blast cleaning process from Rosler Metal Finishing before they are re-melted offers many advantages. Besides the resource-saving use of raw materials, the effective cleaning of the recycling material increases the uptime of the smelting furnaces by significantly reducing the amount of unwanted slag.
Components made from steel, nodular cast iron, and
grey iron can be processed by mass finishing equipment.

Getting castings and forgings ready for the subsequent processing steps presents some of the toughest surface finishing challenges. Shot blasting machines can handle all of these tasks from removing residual sand, casting shells, flashing, die marks, or scale. Whether cast iron, steel, stainless steel, super alloys, titanium, aluminum, zinc, or magnesium, the comprehensive portfolio of Rosler Metal Finishing blasting systems for the foundry industry enables the optimal process for any requirement.
Shot blasting is an essential part of most forge
and foundry operations and has been used since the late 1800s. This specialized
surface finishing process throws small metal (or mineral) pellets, called blast
media, onto the surface of a work piece at incredibly high speeds, ranging from
200-800 feet per second. The impact on the work pieces from this process is
what blasts the contaminants from the parts and produces the desired surface
When properly applied prior to finishing, blasting
achieves three key aspects of the finishing process:
