At Hengjiu, the manufacturing of motorcycle chains begins with the careful selection of premium raw materials and the strict implementation of incoming inspection standards. We employ 160T–200T continuous high-speed precision punching presses along with high-precision molds to achieve component tolerances of up to ±0.02 mm, significantly improving the accuracy and quality of chain plate blanking.
Our quality control personnel remain on-site throughout the production process, utilizing professional measuring instruments and rigorous inspection protocols to ensure dimensional precision and flawless appearance of each component. This meticulous approach guarantees that every chain we produce meets the industry's highest standards—so that every transmission carries reliability, safety, and peace of mind.
