Plastic extrusion is a continuous high volume manufacturing process in which a thermoplastic material is homogeneously melted and then forced out of the shaping die by means of pressure. There are different types of an extruder. Generally, extruders can be classified as continuous or discontinuous extruders.

This process allows for varying thickness, textures, and colors. The die shape used during the extrusion process offers a wide range of shapes and sizes. Additives can be used in the molten plastic to improve the products properties for durability, fire resistance, and friction.
