The materials provided by different

The materials provided by different suppliers are different, even for the same material. It looks the same, but the effect of the materials on the machine will be significantly different, so the material supplier needs to be determined before the formal implementation of the plan. If the material supplier is changed during the process, the previous work may have to be restarted from scratch. This will delay the project schedule and increase costs. At the same time, timely supply needs to be met. During the implementation of the plan, insufficient materials will also cause delays in the project.For product upgrades, it is inevitable to partially modify the equipment. Whether the transformation is successful or not depends on whether the product upgrade is good or bad. The components of the equipment are the key. The components need to match the equipment and can play a key role in removing defects in the product, such as in Tear off the side. Unsuccessful transformation may cause the equipment to lose its original effect.
