“…SKD 11 was chosen for die and punch due to its higher mechanical properties than the workpiece material. Wire cut electro-discharge machining (WC-EDM) was used to create SKD 11, then hardened [5]. The hardness of the SKD material after heat treatment was around 55-58 HRC.…”

This article discussed the design of dies and punched using SUS 316 material for seasoning funnel (SF) applications in the food industry. Cracks in the welding zone in the seasoning funnel (SF) result in leakage of seasonings and result in product mass, which is one of the main parameters in the food industry and a minimum. The damage location on the SF is identical, on the sides of the SF around the bolt holes. The movement of the spice powder, which rotates at high speed, produces a centrifugal force and is then transferred through the SF. The metal structure is becoming increasingly coarser in the area adjacent to the weld melting line. An additional punch with a knocking arm delivers to the SF to expedite the transfer. The knocking arm caused the SF fracture on the SF. SUS 316 sheet metal material for SF without welding is thought to reduce weld damage and speed up the procurement process. The input design for attempting to make dies has been correctly selected as SUS 316 material thickness of 1.0 mm. The two main processes required to form SF from sheet metal were blanking and bending. The SKD-11 material was selected carefully for the main components of the dies and punch. Supporting components such as shank, shaft, top plate, and bottom plate are determined using St 60 material. St 37 material determines the stripper, punch holder, and stopper components. Based on theoretical calculations, the blanking force should be about 225.5 kN. To minimize the burr in the blanking process, dies and punch allowances of 0.1 mm were chosen. The minimum required bending force calculation was 39 kN. A material factor springback value of 0.98 was selected correctly to achieve the desired bending angle. The simultaneous blanking and bending processes necessitated using a 72.96-tonne power press machine.

“…SUS 316 sheet metal material for SF without welding was thought to reduce weld damage and speed up the procurement process. These could be processed by punch and die metal forming processing [5]. Sheet metal forming is a combination of elastic-plastic bending and workpiece strain deformation [6][7].…”

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.

This study discusses the implementation of redox reactions on the thickness test of the galvanized (zinc-coated) layer using the JIS-H-0401 standard to help Small and Medium Enterprises (SMEs) industries. Some of the finished products go through the galvanizing process in the metal processing industry. Quality constraints, especially related to the thickness of the galvanic (zinc-coated) layer, have become an object that is less controlled because of the limitations of the test equipment used. This research uses an experimental method applied to one of its products: a flat washer with SPCC material and a thickness of about 2.20 mm. SPCC - SD material is classified as low carbon steel based on its carbon content. 5-unit flat washers were identified with sample codes A, B, C, D, and E. Flat washers have an internal diameter of 22.65 - 22.7 mm. In comparison, the outer diameter is between 43.75 - 43.80. The redox reaction process uses HCl (hydrochloric acid) with a concentration of 1 M, which is diluted with water (H2O). The zinc thickness test results show that the flat washer has an average thickness of 10.52 microns with a minimum and maximum thickness variation of 10.66 -10.72 microns.
