Below is a list of Plastic Shapes manufacturers from Pittsford, New York. Plastic shapes are specially-formed plastic objects that have been processed by a plastic shaping process. There are many plastic shaping processes, and they include molding, extrusion, casting and other methods. Each method is intended to create a different kind of plastic shape. Molding, for example, is the process best suited for the creation of complex, discrete products. Examples of discrete products include fasteners, pallets and cases for small electronics. Extrusion, on the other hand, allows for the creation of complex, continuous products. Examples of continuous products are trim, hoses and tubes.
