What is Thread Rolling?
Thread rolling is a cold-forming process that creates precise, high-strength external threads by displacing material rather than cutting it. Unlike traditional threading methods, thread rolling enhances the tensile strength, fatigue resistance, and uniformity of threads while maintaining tight tolerances.
Advantages of Thread Rolling
- Stronger threads – Cold-formed threads increase tensile strength and durability.
- Superior finish – Produces smooth, work-hardened surfaces with no burrs.
- High-speed production – Efficient for large-scale manufacturing.
- Minimal material waste – No chips or shavings, reducing material costs.
- Increased wear resistance – Enhanced thread hardness extends component lifespan.
What is Knurling?
Knurling is a machining process used to create textured patterns on metal surfaces for improved grip, aesthetics, or mechanical function. This process is commonly used on hand tools, fasteners, and industrial components requiring a non-slip surface.
Types of Knurling We Offer
- Straight Knurling – Produces parallel grooves for a uniform grip.
- Diagonal Knurling – Angled patterns for enhanced friction and aesthetics.
- Diamond Knurling – A crisscrossed pattern for maximum grip and tactile feel.
