This company adopts and independently developed aluminum extruded machinery hardware and rail guide. Its structure is simple and outlook fantastic. The conveyor chain is the 2.8 times speed chain. The chain roller is made of engineering plastic which is friction-resistant and with low noise pollution. Each circular diameter is processed in a refined manner to allow the seat board conveying motion smooth and free from jumping. During operation, it is quiet. The bumper device used for a workstation is designed with an independently developed bumping resistor so that as the working sheet stops, the motion is smooth and free from reaction.
