In the last years, surface finishing in the automotive industry and motor racing experienced robust growth, a trend that is expected to consolidate with new challenges and opportunities related to fuel efficiency, gas emissions, longer part life, component downsizing and electric vehicles.
Dry electropolishing performs high-quality, fully automated surface finishing increasing efficiency, performance and lifespan of automotive components. Metal-to-metal contact power transfer components like gears, transmission parts, crankshafts and camshafts, bearings and other high value, delicate or complex parts are treated with precision following specific finishing requirements.
The technology is able to improve surfaces with smoothness, precision and negative skewness impacting positively in fuel consumption and CO2 emissions reduction of automotive vehicles.
DLyte surface finishing has also impact in the fatigue life and overall safety and reliability of the parts providing an ultraclean, corrosion resistance and free of burrs surface. Additionally, the process gives auto parts a uniformly bright, shiny and chrome-like appearance.
DLyte also improves the work environment of companies by replacing traditional polishing and hazardous materials. Surface finishing automation protects technicians from exposure to chemical agents in the workplace.
The consumables used are safe and clean, without the risk of generating liquid chemical waste or dust during the polishing process.
DLyte precisely surface smooths, deburrs, rounds and passivates parts made from any manufacturing method, including forging, casting, machining, in the automotive industry.
Common applications are gearbox and engine components, such as cylinder heads and engine blocks, transmission components, fasteners and exhaust systems, fuel lines, bearings, camshafts and crankshafts, injector nozzles, valves and decorative parts.
Among the key technical advantages of the DryLyte technology, it is worth noting the following:
- Extremely low and homogeneous roughness finishes (down to Ra 0.01 microns)
- Geometry preservation, tight tolerances and edge rounding in a controlled way
- Increased resistance to corrosion (30 times more than passivation)
- Reduced coefficient of friction up to 30%, and also reduced fuel consumption
- Noise and heat reduction
- Negative RSK leading to better lubrication and increase of bearing ratio
- Increased part durability
- Faster and absolutely reliable and traceable processes
