Plastics can be some of the most challenging materials to finish using a tumbling machine and media. For this part we were asked to develop a process to remove the excess glass fiber/plastic flashing from the molding process.
Frequently we are asked to deburr and clean parts that have been laser or plasma cut. This is a common application for the C&M Topline Mr. Deburr machine and good results are easily achieved with standard medias.
Plastic parts are notoriously difficult o run in a tumbling process. For this part the goal was to remove the mold parting line and impart a matte finish for a second post process. We chose a fast cutting, large size ceramic media in order to effectively abrade the plastic. The tumbling process has removed the raised parting line quite effectively in a short period of time. This result is seen on all parts both glass and iron filled.
The blades provided had many hours of use in the field at temperature. The surfaces of each blade were blackened by heat exposure. The process significantlybrightened each blade and removed any surface imperfections caused by the combustion process
