Deburring and cleaning plastic components with CO2snow in a single dry process

Jul 19, 2019 Picture:  Plastic parts invariably have burrs after injection molding or mechanical processing. The quattroClean technology from acp systems AG has proved to be an efficient, inline-capable deburring and cleaning alternative for hard and brittle plastics such as PEEK and PPS. Deburring and cleaning are carried out in a single dry process. There are practically no limits to the use of plastics today. From medical technology through automotive engineering and electronics to household and leisure products, polymer all-rounders enable innovative solutions. However, regardless of whether components are injection-molded or mechanically processed, there are residues on the surface that have to be removed for high-quality further processing or to ensure that workpieces and components function perfectly. When it comes to burrs and residues from processing media, the quattroClean technology from acp systems AG is an effective and efficient deburring and cleaning alternative for hard and brittle plastics such as polyphenylene sulfide (PPS) and polyetheretherketone (PEEK). Environmentally-friendly, effective and dry processing step The modular quattroClean system works with liquid carbon dioxide, which has a virtually unlimited shelf life and is generated as a by-product from chemical processes as well as energy generation from biomass. CO2 is therefore an environmentally neutral, non-flammable and non-toxic gas. For the deburring and cleaning process, the carbon dioxide is fed through the non-wearing two-component ring nozzle of the quattroClean system, expanding as it exits to form fine CO2 snow. This is then bundled by a jacketed jet of compressed air and accelerated to supersonic speed. When the non-abrasive jet of snow and compressed air impacts at a temperature of minus 78.5°C onto the surface to be processed, a combination of thermal, mechanical, sublimation and solvent effects take place. The thermal effect is partially responsible for the deburring action. Shock cooling causes the burrs to...
