Manufacturing Methods that Use Plastic
There are a variety of manufacturing processes that are used to shape plastic:
Injecting Molding: Molten plastic is injected into a mold, making multiple copies of the same shape.
Blow Molding: A small amount of soft, heated plastic is squeezed into the end of a mold. Compressed air is then directed at the plastic. This forms a giant bubble that swells to fill the mold. Blow molding is commonly used to make plastic bottles.
Extrusion: Molten plastic is squeezed through a nozzle to make long shapes like plastic sheets.
Compression Molding: A powdered thermostat resin is loaded into mold, where it is compressed and heated. Compression molding is often used for plastic dishes.
