Quality testing control: Hardness and size are tested by every shift, the minimum quantity is five pieces every time. Impact value and dropping is tested by every batch of grinding balls when the quantity is over 200 tons, or as per customers' request. Ensure that all finished products are qualified before packing and delivery. 6.
