Manufacturing process of multicolor hollow filler body

The invention discloses a manufacturing process of a multi-color hollowed-out filler body. The manufacturing process comprises the following steps that a hollowed-out model is arranged in a mold carrier in a sleeved mode; the hollow model is filled with a first material body, then the hollow model is taken down, the first material body is subjected to curing treatment, and an independent first material block is formed; then the mold carrier is continuously filled with a second material body, then the material body is subjected to curing treatment, and a second material block is obtained; and after the material body is solidified and shaped, the mold carrier is taken out to obtain an integrated material block, and finally the integrated material block is taken out and put into a packing material to be assembled to obtain a product. The process is a multi-color transfer printing combined technology, is an innovative transfer printing technology, can combine materials with various colors into a whole, gives mult
