Abstract

The present invention in one or more embodiments provides a method of forming an opening on a panel, the method including pressing in a first direction on the panel to form a protrusion with a tip portion, and cutting the protrusion with a force in a second direction to remove the tip portion to form the opening on the panel, the second direction being different from the first direction. The first direction may be a direction of gravity plus and minus up to 15 degrees. The second direction may be transverse to the first direction with an angle differential there-between of 75 to 105 degrees.

Description

technical field [0001] The present invention relates to a method for forming an opening in a panel, a stamping die used for the method, and a formed vehicle trim panel. Background technique [0002] According to the functional layout requirements of passenger cars, a rear window sill trim panel will be installed between the passenger space and the trunk. Due to the cost-effectiveness of glass fiber reinforced polypropylene, rear sill trim panels are generally made from low cost glass fiber reinforced polypropylene (PP) composites. [0003] In the prior art, during molding, a plurality of ventilation holes are directly stamped on the panel by stamping with a mold. However, during the stamping process, the decorative panel is overstretched by stamping, resulting in white edges adjacent to the edge of the cut. [0004] A PP honeycomb panel is disclosed in Chinese Patent Publication No. CN103407502A. In order to solve the above problems, it seals the edges around the PP honeyc...
