Capsule pins is a pin-type fastener with a head + hollow structure. Its appearance is similar to a capsule. It has the functions of positioning, fixing, and buffering. It is widely used in power tools, door locks, doors and windows, electric vehicles, construction machinery, and household appliances.
1. Lightweight & Cost-Efficient
Hollow Design: Weighs 30–50% less than solid pins — perfect for weight-sensitive applications (e.g., aerospace, drones).
Material Savings: Reduced raw material usage without compromising strength, lowering overall part cost.
2. High Precision & Anti-Loosening
Headed Design: Flanged head(s) prevent axial displacement, even in high-vibration environments.
Interference Fit: The hollow structure expands slightly under compression, improving grip and resistance to loosening.
3. Vibration Damping & Noise Reduction
Elastic Hollow Core: Absorbs shock and vibration, reducing metal-on-metal contact (e.g., automation equipment rails).
Noise Control: Ideal for high-speed moving parts, significantly lowering operational noise.
4. Easy Installation & Maintenance-Free
Pre-Assembly Guide: Chamfered or tapered ends enable quick and smooth insertion.
Self-Locking Design: Eliminates the need for additional retainers (e.g., circlips, pins), simplifying assembly.
5. Corrosion Resistance & Material Flexibility
Multiple Material Options: Stainless steel (304/316), alloy steel (SCM440), aluminum, engineering plastics (POM).
Surface Treatments: Zinc plating, anodizing, nickel plating, and more for use in humid or chemical environments.
