Polishing acrylic sheets is necessary if you want smooth and translucent to clear finishes to your plastic products. There are three main methods of polishing acrylics, each method producing a different result. Different types of products will require a different method of polishing. The three methods used by most fabricators are Diamond polishing, Flame polishing, and manual polishing.
This method results in perfect smoothed out edges on straight or sloping surfaces. Suitable for acrylic materials up to 2100mm in length this method will ensure your product does not have any structural weak spots improving on the longevity of the product. Overall diamond polishing results in attractive and longer-lasting products typically used for high-end retail, thick materials, and items that will be viewed up close.
This method of polishing acrylic sheets involves heating the surface so much that it causes slight melting to create smoothness around the edges. This is necessary on items with edges that are difficult to reach/access or for holes. It’s far cheaper than the other two methods and is faster to do whilst still providing high-quality finishes.
The last method used by plastic fabricators for acrylic sheets is manual polishing. Through utilizing a rotating polishing disk or polishing cloth with paste this method requires extensive manual labor and takes longer than diamond or flame polishing. Manual polishing is commonly used in larger items, low volume items and to repair or remove scratches.
