Paul Murphy Plastics: Revolutionizing with Plastic Extrusion, from Pipes to Deck Railings

December 20, 2023

The article “Surprising Products That Are Made Using Plastic Extrusion” from The Boss Magazine explores the remarkable versatility of plastic as a manufacturing material and the integral role of plastic extruders in shaping a diverse array of products. Authored by The Boss Magazine, this insightful piece sheds light on how companies leverage plastic extrusion for cost-effective and efficient manufacturing.

Plastic extrusion, a high-volume manufacturing method, involves melting unprocessed plastic to create continuous shapes. Specializing in this process, companies produce items such as pipes, tubing, wire insulation, thermoplastic coatings, sheeting, plastic films, window frames, deck railings, fencing, and weather stripping.

In comparison to other manufacturing techniques, plastic extrusion excels in producing parts with uniform wall thickness and extended profiles. This cost-effective method enables continuous production of large material volumes, making it a preferred choice for various applications.

The plastic extrusion process begins with the introduction of plastic material, such as powders, flakes, granules, or pellets, into the extruder’s barrel. The mechanical energy generated by turning screws and heaters gradually melts the material, and the resulting liquid polymer is molded into a continuous shape through a die. This shape solidifies as it cools, creating the final product.

Only thermoplastics, capable of melting from a solid state and resolidifying, can undergo extrusion. Notably, thermoplastics like PVC and polypropylene are well-suited for recycling, contributing to sustainability efforts.
