Q：How to improve the quality of the cell plate hole size ?
A:1. Cell plate hole size spacing to ensure control in ± 1mm, it requires the use of the processing CNC plasma cutting in order to ensure its accuracy. 2. Degree of deformation.Cell plate hole size , should be controlled within 1/1000 , which requires a minimum plate thickness of 6mm , and some ribs to ensure rigidity , while the welding process to ensure the welding distortion control in the smallest range. Flatness 3. Cell plate hole size : should be controlled at ± 2mm / square meter . All these rules in order to ensure the bag to reduce collisions.
