Hand model: Usually newly developed or designed products need to be made with hand boards. Handboard is the first step to verify the feasibility of the product, and it is the most direct and effective method to find the defects, deficiencies and shortcomings of the designed product, so as to improve the defects in a targeted manner until no deficiencies can be found from a single hand board sample. At this time, it is usually necessary to carry out trial production in small batches to find out the shortcomings in the batches and improve them. Generally, the designed products can't be perfect or even usable. Once the direct production is defective, it will all be scrapped, which greatly wastes manpower, material resources and time. Generally speaking, there are few samples on the hand board, the production cycle is short, and the manpower and material resources are consumed. It can quickly find the shortcomings of product design and improve it, providing sufficient basis for product finalization and mass production.
