When the washing machine is in high-speed dehydration mode, the drum rotates at a speed of over a thousand revolutions per minute, and the reinforcing ring is a key component for ensuring structural stability.
Common problems:
The design of the bending radius is unreasonable, causing cracks in the reinforcing ring during long-term operation;
Excessive residual stress during the molding process leads to significant deformation after welding;
The material properties of different batches vary, resulting in insufficient consistency.
Solution for molding equipment:
Use multi-stage progressive molding to avoid excessive concentration of stress at a single point;
Equip online straightening devices at key parts to reduce residual stress;
The mold design should take into account the elastic recovery differences of different material batches.
For appliance manufacturers, these details determine the long-term durability of the washing machine and are also the foundation for users' trust in the brand.
