Extrusion molding is a manufacturing process used to create objects with a fixed cross-sectional profile. In this method, raw plastic material is heated until it melts and then forced through a shaped die. The molten material cools and solidifies as it exits the die, forming continuous lengths of the desired shape, such as pipes, sheets, or profiles. This technique is widely used in the production of various plastic products due to its efficiency and ability to produce complex shapes. Extrusion molding is commonly employed in industries like construction, automotive, and packaging, making it a vital process in modern manufacturing.
