Vacuum forming plastic is a process for shaping plastics.Thermoforming is actually a process that refers to the conversion of a thermoplastic sheet into a three-dimensional shape using vacuum and pressure, and it has advantages over injection molding methods.
Vacuum forming plastic (thermoforming) Applications:
Production of disposable containers made of plastic or foam. These containers come in a variety of types, such as: closed containers, cups, and lidded containers.Packaging of food products that are made of plastic. Pre-made molds must be used to prepare them.Packaging of pharmaceutical products.Liner for refrigerators and freezers.Thermoforming is actually one of the oldest methods of making plastic parts. In this process, the raw material is first exposed to heat in the form of a roll or sheet until it reaches a temperature at which it can be shaped.The heat is not so high that it melts the plastic. Heat is generated by heating elements in a single or double container with a predetermined distance. After the sheet is heated and softened, it is shaped using a mold.Molds are mainly made of wood and aluminum.In mass production using the thermoforming method, a plastic roll or an extrusion machine is used in the process. Sheets up to a thickness of 1.5 mm are used as rolls, and sheets with a greater thickness are used as sheets.The thermoforming method is much more economical and efficient than the injection molding method. Its mold is much faster to prepare than the injection molding mold, and it is less expensive.In addition, making a mold made of aluminum is cheaper and faster than making it from steel. Also, the cost of setting up a production line is much cheaper than the injection molding method.
