Learning Objectives for Pipe Extrusion
Master the essential knowledge, skills, and professional qualities required for successful pipe extrusion manufacturing processes.
Introduction to Pipe Extrusion
Plastic pipes are one of the main products manufactured using the extrusion molding method. This process involves continuous production where molten material from an extruder is forced through an annular die gap, compacted, cooled, and shaped. Pipe extrusion is a versatile manufacturing process that produces a wide range of plastic pipe products.
There are many types of plastic pipe products, divided into two main categories: rigid pipes and flexible pipes. These include water supply pipes and sewage pipes for urban construction, agricultural irrigation pipes, chemical pipelines, oil pipes, and electrical insulation pipes for energy and communication applications. In pipe extrusion, the design of the die structure and the precision of process parameter control play a crucial role in determining the quality of the final pipe products.
