PMMA has the advantages of light weight, low price, and easy molding. Its molding methods include casting, injection molding, machining, thermoforming, etc. Especially for injection molding, mass production can be achieved, the manufacturing process is simple, and the cost is low. Therefore, its application is becoming more and more extensive. It is widely used in instrument and meter parts, automobile lights, optical lenses, transparent pipes, etc.
