The packing methods and principles of the iron flower racks of Changzhou Yixinhong Machinery Co., Ltd. during transportation are as follows:
  
1. The principle of minimum volume: in order to save transportation costs and achieve portability and easy handling, the packaging method must be considered in packaging design to minimize the packaging volume;
  
2. Easy to install and take away principle: When designing the packing of iron flower racks, it is necessary to consider the convenience and fluency of operators in packing and unpacking, and do not make it difficult for operators to operate due to design defects.
  
3. Principle of low center of gravity: During packaging design, the center of gravity of the whole box should be low to increase stability.
  
4. The external design of the packing box is reasonable: to ensure the structural rigidity, the ratio of the length and width of the packing box is recommended not to be greater than 2.5:1; The ratio of height to width shall not be greater than 2:1 and not less than 0.15:1.
