What is the difference between extruded nylon sheet and cast nylon sheet?

The main difference between extruded nylon sheet and cast nylon sheet (also known as MC nylon sheet) lies in their manufacturing processes, resulting in significant differences in performance and application scenarios. Simply put, cast nylon offers higher strength, greater wear resistance, and can be produced in larger sizes, but it is more expensive. Extruded nylon, is cost-effective and highly efficient to produce, making it ideal for standard, general-purpose components.

Process Differences Between Extruded and Cast Nylon Sheet

Extruded nylon sheet: After heating and melting the nylon raw material, it is extruded through a screw and then formed into continuous sheets by a die. These sheets are then cooled and shaped, and subsequently cut to the specified dimensions.

The cast nylon sheet is carried out using the monomer casting process: The activated nylon monomer (such as caprolactam) is directly injected into the mold, and then polymerizes and solidifies at room temperature or low temperature. After demolding, the plates are directly obtained, which is a “one-step process”.

Comparison of the performance between extruded nylon sheet and cast nylon sheet

The cast nylon sheet have a higher molecular weight, greater crystallinity, and a more compact and uniform internal structure. As a result, their strength, rigidity, and wear resistance are more outstanding. Moreover, the finished products have almost no internal stress and can be used to produce large-sized components.

The extruded nylon sheet has balanced comprehensive properties. Its mechanical strength, rigidity and toughness are all good, but its overall strength and wear resistance are not as good as those of cast nylon. It is suitable for applications where the force is moderate.

Extruded nylon sheet and cast nylon sheet classification

Extruded nylon sheet: PA6 nylon sheet, PA66 nylon sheet, PA46 nylon sheet, PA6 GF30 nylon sheet, PA66 GF30 nylon sheet, PA66 MOS2 nylon sheet

Cast nylon sheet: MC nylon sheet, MC901 nylon sheet, oil filled nylon plates, glass filled nylon sheet, MOS2 nylon sheet, solid lubricant nylon sheet

Extruded nylon sheet specifications and cast nylon sheet specifications

Specifications of the extruded nylon sheet: 2000×1000×1 – 100mm, 1000×1000×1 – 100mm. Colors: natural color, black, blue, green, red, purple, etc.

Specifications of the cast nylon sheet: 2400×1200×5 – 300mm, 2000×1000×5 – 300mm, 2500×1250×5 – 300mm, 2400×1200×5 – 300mm, 2050×1040×5 – 300mm, 1000×1000×5 – 300mm  Colors: Natural color, black, blue, green, red, purple, etc.

How to correctly choose between extruded nylon sheet and cast nylon sheet?

Based on the differences in process and performance between extruded nylon sheet and cast nylon sheet, if you need to process large-sized components with high load-bearing capacity, high wear resistance, and high impact resistance, it is more appropriate to choose cast nylon sheet, such as shaft sleeves, gears, and wear-resistant plates for mining machinery. If you need to process ordinary gaskets, stop blocks, and conventional structural components, and you are seeking cost-effectiveness and forming efficiency, then extruded nylon sheet is a better choice.
