Thermoplastic materials are widely used across various industries due to their versatility, durability, and ease of processing. However, like all materials, thermoplastics exhibit certain behaviors under specific conditions that can impact their performance. One such behavior is creep, a time-dependent deformation under constant stress. Understanding thermoplastic creep is essential for engineers and designers to ensure the longevity and reliability of products.
Extrusion is a popular manufacturing process used to create parts with a consistent cross-sectional profile. It involves forcing material through a die to shape it into a continuous profile, which can then be cut to the desired length. When designing parts for extrusion, several critical factors must be considered to ensure optimal performance, manufacturability, and cost-effectiveness. Here are some key considerations and best practices for designing extruded parts.
