Balancer welding can be by hot plate welder or spin welder. Spin welder means applying spindle rotation to drive friction at contact surface of two balancer halves to case heating energy to melt thermoplastic and achieve welding. Comparing to hot plate welding, spin welding cycle time is much more short, normally about 10S, and more stable in welding performance to ensure quality.
MP Sonic developed MPS-T00KB Series equipment for the joining of balancer with method of spin welding. MPS-T00KB balancer welder applies servo motor system in with high torque output to achieves high welding ability. Servo system or servo controlled hydraulic system is applied to force the clamping of welding to ensure the welding strength.
Spin welding is a kind of frictional joining technique in capability of producing strong, air-tight welding to parts with a circular-axis jointing, which with high bond strength / hermeticity requirements. During spin friction welding, one part half is held stationary in a holding fixture while the other one is rotated against it under pressure at a high speed normally 80~1600 rpm, which results friction at the touch area of two part halves (means the joining area) and causes the joining surfaces to melt until form fuse together, after which stop rotation and keep two part halves together under pressure until the interface of the jointing area cool down and become solidification.
