Abstract

The material manufacturing process involving the deep drawing process is often challenging in small and medium industries. That is due to the many complicated parameters that must be overcome during the process. The deep drawing is a complex steel forming process because it involves blank dimensions, dimension/height ratio (D/H ratio), and die/punches tolerance (D/P allowance). Failure to identify blank dimensions and D/H ratio will result in defects in the production process, such as tears and wrinkles. This service aims to help MSMEs overcome common failures in production processes involving deep drawing. This community service article discusses technology dissemination to small business groups (UKM) for the deep drawing process in producing R-ornament #3D40x40 components involving these three variables. R-ornament #3D40x40 is produced using SPCC-SD material with a thickness of 0.8 mm. The participatory action research (PAR) method approach assists MSMEs in optimizing blank dimensions, D/H ratio, and D/P allowance simultaneously with partners. Identification of a D/P allowance of 1.41 mm has eliminated wrinkle defects in the product. Identifying deep drawing parameters has helped MSMEs overcome the production process so that tearing and wrinkle defects do not occur.

Abstract

The deep drawing is a complex steel forming method involving blank dimensions, dimension/height ratio (D/H ratio), and clearance between die and punch (D/P allowance). Failure to identify proper blank dimensions and D/H ratio can lead to production defects such as tears, while failure to recognize the correct clearance can cause wrinkles. This article discusses technology dissemination to Small and medium-sized enterprises (SMEs) for the deep drawing process in producing R-ornament components #3D40x40, considering these crucial parameters. R-ornament #3D40x40 was manufactured using SPCC-SD material with a thickness of 0.65 mm. The Participatory Action Research (PAR) method was employed to collaboratively optimize blank dimensions, D/H ratio, and dies/punch (D/P) allowance with partners. The optimization of blank dimensions successfully eliminated the need for the trimming process, resulting in reduced investment costs in dies and die setup by IDR 15 million and 2.16 million, respectively. Identifying a D/H ratio of 1.32 successfully eliminated tear defects and determining a D/P allowance of 0.87 mm on each side eradicated wrinkle defects in the product. This article contributes to Goal 9 of the Sustainable Development Goals (SDGs), specifically focusing on the Small and Medium-sized Enterprises (SMEs) sector.
