Washer Balancer Welding & Liquid Filling

Spin welding is the best method to be applied to weld washer balancer because of its advantages of stability welding performance, high welding qualification rate, high production efficiency. As well it can add automatic liquid filling system which is help to simplify the balance assembling process, reducing labors and equipment invested.

Washer balancer is the system keeping washer drum in balance during rotation. To ensure enough centrifugal force during rotating, salt solution in a fixed concentration need to keep inside of balancer, thus it requests airtight welding to balancer.




Washer Balancer Welder


I. Main information of balancer:

   1. Material: normally is PP;

   2. Diameter: normally 260~480(mm);

II. Requirement to Balancer:

    1. Airtightness in welding;

    2. Uniform in volume of solution inside balancer;

    3. Uniform in concentration of solution;

    4. Welding strength to balancer.

III. Challenging of Balance Assembly Production:

    1. Big diameter of balancer;

    2. Big deformation and shrinkage difference of balancer parts molding; 

    3. The causticity of solution to equipment.

IV.  Assembly Method for Balancer:

     A. Three steps process: hot plate welding + Solution Filling + Ultrasonic Sealing;

    B. Automatic Solution Filling + Spin Welding.

V. Benefit from Spin Welding + Solution Filling:

    1. High welding efficiency by spindle welding. Spin welding cycle time is less than 1/3 of hot plate welding (hot plate welding cycle time is 30~40S);

    2. Stability in welding performance and high welding qualification rate;

    3. Fills solution before balance welding, no need to seal the hole after solution which it has to if weld by hot platen, the production efficiency is higher (total cycle time is around 20S), as well the investigation into labor and equipment is much lower.
