Nylon is one of the most widely used engineering thermoplastics. It offers an excellent combination of mechanical performance and cost. There are many nylon grades available today, the most common being nylon 6/6 and nylon 6. The properties of both nylon products are very similar; and typically, they can be used interchangeably. However, there are some advantages and limitations to each material both nylon 6/6 and nylon 6.
Cast nylon 6 (polycaprolactam) has similar mechanical properties to extruded nylon 6/6; however, it cast nylon 6 has some distinct advantages. Cast nylon 6 is often less expensive to produce, especially for large geometries, large cross-sections, etc. The casting process of cast nylon 6 results in less stress than the extrusion process, thus providing better dimensional stability. Custom irregularly shaped parts can be cast to "near-net" geometries thereby reducing machining time.
