The design idea of turnover material rack can be based on the form of parts provided by customers. If the customer provides the part entity, it is a great help for the design; another channel is the customer provides 3D data. Automotive logistics packaging network considers that non-standard rack suppliers can measure the size and weight of parts according to the entity. Through communication with customers, understand the frequency of delivery of this part, circulation environment, packaging specifications of the host factory for delivery. The circulation environment needs to know whether to transport to the station side of the assembly workshop through the turnover rack, whether to sort, stack, whether to support the hook, what color to use, etc. For shelf manufacturers, it is better to know the shelf specifications of the main factories supplied by customers through customers, otherwise the shelves designed by oneself for several days can not pass the audit of the main factories, which wastes time and money.
