Extruder Moulding for PA66 Thermal Break Strips | POLYWELL Solutions

The term "extruder moulding" is not a standard technical term within the plastics industry and is likely a conflation of two distinct processes: extrusion and injection moulding. To ensure clarity, it is essential to distinguish between them. Extrusion is a continuous process used to create long, uniform products like pipes, profiles, and sheets. In extrusion, material is continuously melted and forced through a die to form a specific cross-section. Injection Moulding, on the other hand, is a cyclical process where a specific amount of molten plastic is injected into a closed, cooled mould cavity under high pressure to produce discrete, three-dimensional parts. The machinery, process controls, and final products for these two methods are fundamentally different. Therefore, in professional communication, it is crucial to use the precise terms. If the context involves creating long, continuous shapes, the correct term is "extrusion." If it involves producing individual, complex parts like housings or containers, the correct term is "injection moulding." Using the accurate terminology prevents misunderstanding and ensures effective collaboration in manufacturing and engineering projects.
