  • Publication number: 20070262492
    Abstract: Method for finishing a machined and cut acrylic piece to eliminate porosity of the cut and machined surfaces includes exposing all sides of the piece, then inserting the exposed piece into a heated oven, keeping the piece in the oven while the oven is maintained at a set temperature or within a set temperature range, and then removing the piece from the oven after the predetermined period of time. After this beating cycle, the machined and cut surfaces are non-stressed and therefore the acrylic piece is resistant to forming striations even when the cut and machined surfaces are exposed to oil and chemicals which cause striations in machined and cut surfaces of non-treated acrylic pieces. The predetermined period of time for heating the piece depends on a thickness of the piece and on whether the temperature in the oven environment is measured and controlled.
