Critical aerospace components require first-class surface treatment. From engines, fuselage, wings, and landing gear to seats, gears, propellers, blades, fasteners and tanks for fuel, water, and waste, Rosler has industry experience and expertise.
While mass finishing and shot blasting methods are equally useful to manufacturers of new components and in the overhaul and repair of existing components, shot peening – a particular type of shot blasting – is especially advantageous for aerospace work pieces thanks to its ability to provide surface finishing and create internal compressive stress for improved component life.
Shot Blasting Capabilities
Rosler’s shot blasting technology meets the strict surface finishing requirements predicated by tight tolerances for safety and longevity. This impact-based process propels small metal or mineral pellets onto a work surface at speeds of 200-800 feet per second.
Desired finishes including cleaning, texturing, removal of or preparation for coating, and peening can be pinpointed to specific areas of a given work piece as well as the entirety of large, structural components.
During mass finishing, the process water injected into the finishing machine is contaminated with the chemical ingredients of the compounds, fines from the grinding or polishing media, and metal fines from the work pieces.
In case of ball burnishing, when acidic or alkaline compounds are used, the process water can also contain dissolved metals or be alkaline or acidic. Or, for example, when the work pieces are covered with oil from machining or stamping operations, the water can even be contaminated with oil.
Rosler has developed a series of closed-loop, water circulation systems using centrifuge technology to remove these contaminants regardless of their origin and allow clean process water to be reused and/or safely discharged. In addition to offering more effective work piece processing, cleaning process water saves money and the environment through reduced consumption, compound usage, disposal costs, and regulations.
Rosler Metal Finishing has decades of experience in the forge and foundry industries, especially when it comes to mass finishing for die-casted work pieces.
Our Forge & Foundry Blog Series continues with an overview of our top five mass finishing machines for precise cleaning of die castings.
Standard Rotary Vibrators
Media and parts are placed into a circular processing bowl in standard rotary vibrators. The energy from a vibratory motor causes the media and parts to freely tumble over each other. Some models are equipped with an internal separation device for separating the finished work pieces from the media.
Rotary vibrators can be used for batch and continuous feed processing.
Rosler’s standard rotary vibrator models include the models EC, Euro, A, and R.
Ideal Work Pieces — Small to fist-sized die-castings such as shoe buckles, furniture fittings, gear shifter forks, electrical components
Finding a solution to our clients’ needs is nothing new for Rosler, nor is combining multiple solutions into a single finishing system. Take our work with Polish brake pad manufacturer Lumag Sp. z o.o. (Lumag), for example.
When they faced the challenge of de-oiling, deburring, and surface roughening brake pad carrier plates as part of their punch press process, they turned to us for a cleaning and mass finishing solution.
Upon its founding in 1988 by Marek Zak, Lumag specialized in the production of brake linings. As the company implemented its own brake pad manufacturing technology, their products and offerings evolved. In addition to achieving enormous technological progress and applied engineering solutions, Lumag amassed a collection of machinery in need of constant upgrades and integration.
In order to meet the continuous rise of quality and safety standards for its brake pads for drum and disk brakes for commercial vehicles as well as brake pads for passenger cars and motorcycles under the trade name Breck, Lumag needed a partner with automotive expertise who could combine multiple solutions in a single system.
