Thermoplastic vacuum forming

WebbIn a thermoforming process, a plastic sheet is warmed and formed into a cavity (or over a tool) using vacuum, air pressure or mechanical means. From: Durability and Reliability of … WebbVacuum forming is also known as the simplest form of plastic thermoforming as only a mold is required, and the plastic is placed over it. There are two types of molds that are used in vacuum forming that are: Male or positive mold Female or negative mold The male or positive mold is a convex-shaped one.

WebbTo use a vacuum forming machine, you must: Heat the plastic to a temperature where it becomes malleable. This can range between 100 and 225 degrees Celsius. When the optimum temperature has been reached, lay the plastic onto a mould, usually made of wood, machined aluminium or structural foam. WebbABS – which stands for Acrylonitrile Butadiene Styrene – is an amorphous thermoplastic that is very rigid. Its hard surface has excellent weather resistance and containing rubber means that ABS has a great impact resistance too. ABS is very popular when it comes to vacuum forming as its shrinkage rate ranges between 0.3-0.8%.
