Abstract
Description
Technical Field
[0001] The present application relates to the technical field of foam processing, and in particular to an assembly and stacking process of ultra-thick foam. Background Art
[0002] At present, there are two molding methods for super thick foam products (thickness ≥ 5MM) in the die-cutting processing industry. The first one is die punching molding. This process uses die punching molding. The mold is designed to correspond to the shape of the product, and the punching is half cut on the carrier. Because the super thick foam is thicker, the foam material will be compressed when the mold is punching, resulting in the product being in a compressed state when the actual mold blade cuts. After punching, the foam rebounds, resulting in a beveled surface on the edge of the product, which cannot meet the customer's product size and appearance requirements. The second one is laser molding. This process uses a laser tube to refract the laser to burn the product. The edge of the product will be removed and cut along the laser scanning area to achieve the shape of the product to meet the molding effect. This method will not produce extrusion and beveled surfaces, but the foam surface is prone to burn edges and burns. The cut foam will shrink when it encounters the laser, resulting in the foam being trapezoidal in shape, which cannot meet the requirements of customers with appearance requirements.
