Cast Nylon Quick Guide: Uses, Specifications & Buying Checklist
2025-10-02

Why Learn About Cast Nylon?
In industrial parts and equipment maintenance, common challenges include heavy metal components, frequent wear, and high replacement costs. Cast nylon is increasingly chosen as a replacement material thanks to its light weight, wear resistance, and cost-effectiveness.
What Is Cast Nylon?
Cast nylon is an engineering plastic manufactured through a casting process, primarily derived from nylon 6 monomer. Compared with extruded nylon, cast nylon offers higher molecular weight, greater mechanical stability, and the ability to produce large-size components, making it widely used in machinery, automotive, and food equipment industries.
Common Types of Cast Nylon
MC Nylon 6 – Standard grade, versatile, suitable for most mechanical components.
MC901 – Modified wear-resistant grade, commonly used for gears and pulleys.
MC907 – Low-noise, chemical-resistant grade, ideal for food machinery transmission parts.
Special modified grades – Enhanced with lubricants, impact modifiers, or other additives for demanding applications.
👉 Example: In food conveyor systems, MC907 can replace metal bushings, reducing both noise and lubrication requirements.
How to Select & Use (Step-by-Step)
Define the application – Load-bearing? Transmission? Wear resistance?
Check specifications – Select the right diameter, thickness, and color.
Confirm machining methods – Turning, milling, and drilling are suitable; avoid overheating to prevent deformation.
Review storage conditions – Limit moisture absorption to maintain dimensional accuracy.
Bonus Tips
Always confirm the material grade (e.g., MC901, MC907) before purchase to avoid confusion.
Request cutting or customization services in advance to save on secondary machining costs.
Use sealed, dry packaging for storage to extend shelf life.
Key Takeaways
Cast nylon is a cost-effective engineering plastic, especially suitable for metal replacement and weight reduction.
Common grades include MC Nylon 6, MC901, and MC907.
For procurement, focus on application → specifications → machining & storage.
