Flame polishing

Tricky but quick

Manufacturers do not recommend this technique, but many fabricators flame polish plastic edges because the procedure is simple and fast. The problem with flame polishing is that it can cause crazing on the surface of the sheet, and this may not show up until weeks after the piece has been polished. If you are careful not to overheat the plastic, flame polishing produces a crystal-clear edge faster than any other method.

Light a propane torch and position the tip so that the blue inner cone of flame just touches the edge of the plastic as shown below. Move the flame back and forth across a small area several times, watching carefully for signs of distortion or burning. The object is to apply only enough heat to melt the rough edges and form a clear, smooth finish. Use only on acrylic and polycarbonate plastics.

Flame polishing requires careful control to avoid damaging the plastic.
