The materials provided by different suppliers are different, even the same material. The effect of materials on the machine will be obviously different, so it is necessary to determine the material supplier before the plan is formally implemented. If the material supplier is changed during this process, the previous work may need to be started from scratch. This will delay the progress of the project and increase the cost. At the same time, material suppliers can supply materials in time, and in the process of plan implementation, insufficient materials will also cause project delay.<br> For product upgrading, it is inevitable to partially modify the equipment. Whether the transformation is successful or not depends on the quality of product upgrading, and the components of the equipment are also the key. These components need to match the equipment and play a key role in eliminating product defects, such as removing waste edges. Unsuccessful transformation may cause the equipment to lose its original effect.
