Extrusion envelopment is a manufacturing process used to create hollow, tubular structures by forcing a material through a die of a smaller cross-section than the material being extruded. This process is commonly used in the production of pipes, tubes, and other hollow profiles. The material, typically a thermoplastic or metal, is heated to a plastic or molten state and then forced through the die under high pressure. The die has a mandrel inside it, which the material flows around to create the hollow structure. The mandrel can be withdrawn gradually as the material cools and solidifies, resulting in a seamless, hollow product. Extrusion envelopment is known for its ability to produce high-quality, consistent products with precise dimensions and smooth surfaces. It is widely used in various industries, including plumbing, automotive, and construction, for the production of pipes, hoses, and other components. The process offers several advantages, such as the ability to produce long lengths of material continuously, the potential for cost savings through reduced material waste, and the capability to integrate multiple materials or reinforcements within the extruded profile. However, it also has some limitations, such as the need for specialized equipment and the potential for material degradation at high temperatures and pressures. Overall, extrusion envelopment is a versatile and efficient manufacturing process with a wide range of applications.
