Blast cleaning of springs prior to coating
Shot blasting is the most common pre-treatment technology to prepare the surface of technical springs for subsequent coating operations. In a newly established manufacturing line for compression springs this cleaning operation takes place in a Rösler tumble belt blast machine.
Painted per customer specifications, the “RMBC 4.2-HD” is equipped with special technical features to allow the perfect blast cleaning of the compression springs as preparation for the subsequent coating process. To neutralize oil carried into the shot blast machine by the work pieces, the machine can be equipped with a dosing system for the application of a powder compound that catches and discharges the oil. © Rösler

The shot blast machine is equipped with two high performance “Gamma 300G” turbines, each with an installed power of 11kW. This ensures short cycle times. Compared to conventional turbines the Gamma 300G turbines are equipped with specially designed, curved throwing blades generating an up to 20% higher blast performance. © Rösler
The automatic blast media flow control allows not only the monitoring but also the precise adjustment of the media flow to the respective work pieces. The media replenishment is also fully automatic. © Rösler
