Our HANDUN conveyor chains are obtained high quality by experienced chain design, strictly quality control in every process and advanced equipments. With more than 45 years experiences in engineer chain, 25 engineers in conveyor chain team and chain conveyor team, we have served for hundreds of industry in China. As an industry partner, we cooperated with many famous companies in China and are familiar with working conditions in various industries.
1. Fatigue Strength
smooth surface of pitch holes . thinner plates thicker plates produced by cutter machine, and processed holes in CNC machine. heat treatment for optimal strength and maximum breaking loads. shot peening for plate, bush and roller to improve the parts fatigue performance.
2. Wear Resistance
selection of the best materials for appropriate heattreatment. optimal hardening penetration through induction or case hardening poifns and bushings.providing longer service life and less downtime.
3. Reliability
use hydraulic chain assembly line to get perfect fits between pins, bushings and link plates. high precision pitch control ensures smooth. operation of the chain.100 % inspection from incoming materials spectrometer analysis to final products.
4. Services
complete chain conveyor solutions. personalized conveyor chains suitable for customers' applications. strong machining and welding ability to supply sprocket, shaft, couplings to serve together.

We build a first-class modern chain testing organization and capability. Quality inspection covering the entire process of chain design to manufacturing. The main testing items include physical and chemical properties test of raw materials, accuracy test of chain components, tensile strength, chain length accuracy, pressing force, chain wear test, fatigue test, salt spray test, Impact resistance test, etc.
We believe that design and craftsmanship are prerequisites for quality assurance, and advanced manufacturing equipment and quality control measures are the guarantee of quality.
