Capping Heads | ±0.05N·m Precision, Multi-Mode Torque Control for Reliable Sealing

Capping heads are the heart of capping machines, responsible for precise cap handling, reliable tightening, and torque control—directly determining seal integrity and production efficiency. Modern capping heads have evolved into intelligent modules integrating precision mechanics, real-time sensing, and data communication. Key strengths include precision torque control: supporting constant torque, angle, or yield-point modes with accuracy up to ±0.05 N·m (high-end models). High-response sensors enable real-time dynamic compensation, ensuring >99.8% consistency within batches. Soft-start and cushioning technology prevent “cap jumping” and impact damage during initial engagement. For seal reliability, precise torque and depth control achieve ≥99.9% sealing pass rates across cap types (press-on, break-away, tamper-evident), while automatically adapting to minor variations in bottle height or thread start position. Wear-critical parts use ceramic coatings, PEEK, or tungsten carbide—enabling lifespans of millions to tens of millions of cycles. The body is made from high-strength aluminum or stainless steel (FEA-optimized), offering long MTBF. Smooth, crevice-free design meets FDA/EU food-grade standards and supports CIP cleaning. Operating speeds reach 120–180 bottles/minute per head, with noise <75 dB. Investing in high-performance capping heads is essential for maximizing line efficiency and product quality.
