Abstract
The invention relates to a one-step forming wet production process of an automobile calash, which comprises the steps of rolling plastic on a calash PU matrix, spraying demineralized water, combining a base material, press-forming, cooling, shaping, carrying out waterjet cutting, assembling accessories, inspecting, packaging and the like. The one-step forming wet production process eliminates the step of secondarily jointing a fabric with the base material in the prior art and directly coats the fabric on the base material for one-step press-forming, thereby reducing the process steps, shortening the operation time and improving the process conditions. The produced calash can lead the sound absorption to achieve the grade 3 international leading level, greatly reduce the weight of the calash and meet the requirement on lightweight design of a whole automobile; the product has high rigidity, and can not be broken off or droop; the product is produced by adopting an automatic production line during the whole production process, thereby greatly reducing the labor intensity of workers during the production process and improving the production efficiency; and the product does not produce hazardous substances during the whole production process, thereby being environment-friendly and pollution-free.
