WebbThermoforming is a plastic manufacturing process that involves heating a plastic sheet and forming it using a mold to specific shapes. The shaped plastic then gets cooled down and trimmed to result in the finished part. The process is executed using a thermoforming machine to heat and stretch the pliable thermoplastic sheet over the mold. Webb22 jan. 2024 · PMMA (polymethyl methacrylate) is a transparent and rigid thermoplastic material. It is also known as acrylic, acrylic glass and plexiglass. PMMA is widely used in the production of lenses, diffusers and light guides in lighting industry because of its high light transmittance providing property.

Webb9 mars 2024 · PMMA is an optically clear (transparent) thermoplastic, and it is widely used as a substitute for inorganic glass, because it shows high impact strength, is lightweight, shatter-resistant, and exhibits favorable processing conditions. [3] Outstanding properties include weather resistance and scratch resistance. Webb4 maj 2024 · PMMA holds its formed shape as it cools down to be machined, drilled, or sawed. When it is shaped, molds can be made from wood or plastic, which is cost-effective. Because it is thermoplastic and softens under high temperatures, acrylic can be formed into virtually any shape.
