The yield stress of any plastic is usually not use to describe the material because all plastics yielding stress is a function of the rate at which it is loaded and its temperature. For example if you leave something like silly putty on the corner of a table it will eventually creep over the edge of the table under its own weight, but if you cool it down to can use it to hit nails into wood. Same thing applies to poly-carbonate and other plastics just to a lesser extent. Often the ultimate stress is used to determine if a plastic will fail but even that assumes that the plastic is a room temperature.

Thermoforming is done by heating a sheet of plastic to a certain temperature, at which point it can be shaped or molded into a desirable product. After cooling, excessive plastic is trimmed away and one is left with a usable part or product to sell.
Vacuum forming is a simplified form of thermoforming. Thermoforming heats plastic to a certain temperature, and is put on a mold while applying a vacuum to the mold.
Plastic thermoforming is a manufacturing process whereby a sheet of plastic is heated to a point where it is pliable, shaped to form an object and trimmed to form a useful product. Due to the plastic that is cut off or left over after the product is shaped, many production lines recycle the scraps to improve efficiency and reduce costs.

The company Molded Plastic Industries offer a variety of solutions for molded and plastic thermoforming services needed for industry. Examples included composite thermoplastics.
Vacuum forming is one of the most common methods of processing plastic. The vacuum forming process involves heating a sheet of plastic until it is soft.
