Order Cast Nylon at Piedmont Plastics
Cast nylon, also known as nylon 6 or polyamide 6 cast (PA6 C), is an engineering plastic with superior performance and versatility. It’s manufactured through a casting process that boosts its mechanical strengths, like toughness and stability, making cast nylon a great choice for industrial and mechanical applications.
Able to be cast in large or custom diameter rods, tubes, and sheets, nylon 6 is highly resistant to wear, abrasion, and impacts, which can extend the lifespan of various products and components. One of the best advantages of cast nylon is its durability and how well it works with minimal lubrication, helping to cut down on maintenance costs and equipment downtime. Near net casting allows for better yields and more cost-effective parts.
Cast nylon is often used to make gears, bearings, and rollers and is crucial in areas like the automotive, electronics, and industrial machinery sectors where strong materials are needed. Nylon 6 can replace metal bearings and bushings to reduce weight, minimize lubrication needs, decrease wear and noise, and lower labor and downtime costs. It's also easy to shape and machine, which makes it a versatile option for customized projects. This adaptability and strength ensure that cast nylon can meet the tough demands of engineers and designers who need dependable and effective materials.
Whether you're in need of cast nylon rod for structural components, cast nylon tube for fluid handling systems, or cast nylon sheet for large scale industrial projects, Piedmont Plastics offers expert guidance and a comprehensive selection of products to meet your specific needs. We can even provide customized services to meet your project’s exact specifications.

Key Features of Our Cast Nylon
Cast nylon possesses many features that make it a top choice in numerous applications. Here’s a closer look at the key attributes of this versatile material:
High Impact and Wear Resistance: Cast nylon boasts excellent resistance to impacts, wear, and tear without deforming or cracking under stress. This makes it suitable for components that undergo intense friction, constant movement, and frequent shocks.
Self-lubricating: Cast nylon has a low coefficient of friction, reducing the need for additional lubrication and minimizing maintenance requirements.
Easy to Machine: This material can be easily cut, drilled, and shaped with standard metalworking tools, allowing for high precision and complex designs in manufacturing without the need for specialized equipment.
Corrosion and Chemical Resistance: Unlike metals, cast nylon does not rust or corrode, making it an excellent choice for applications exposed to corrosive substances, chemicals, or environments.
High Compression Strength: Cast nylon can withstand high compressive loads, which is crucial for structural components that must support substantial weight or force without compromising their integrity.
High Heat Tolerance: Cast nylon maintains its form and function under elevated temperatures, which is beneficial for applications involving heat-intensive processes.
Light Weight: The lightweight characteristics of cast nylon make it easier to install, fabricate, and transport, thus also providing cost savings.
FDA Compliance: Certified grades of cast nylon are safe for direct contact with food.
These features collectively make cast nylon an adaptable and effective material across a spectrum of applications, ensuring both performance and durability in the most demanding conditions.
