The invention relates to a molding method of stainless steel groove, wherein it comprises: selecting the type of stainless steel sheet, to process the panel via pressure device; compressing the panel to form the coil with step edge, then cutting edge and punching to cut and flatten the edge; punching the bottom, to form the stainless panel whose inner wall corner of bottom through hole is alpha; processing the groove; filling material based on the matched panel; then drawing with pressure device, to form the groove with edge; then drawing the groove again, to form the match groove whose outer wall corner is beta; then cutting edge and punching to form the stainless steel groove whose bottom has water hole; at last, arranging sealing adhesive bar at the bottom step, to be put with stainless steel groove, to fix them. The invention can reduce the cost. |
