“…The working process of this tool is based on the compressive force that is transmitted by the punch to cut the gasket according to the desired geometry and size. Piercing produces residue in the form of thin pieces with a variety of shapes and sizes based on the shape of the punch tip and the hole in the dies [25].…”

The Ge Nose C19 medical device gasket is a product from a manufacturing company in Yogya. Gaskets must be of good quality to ensure vacuum or prevent air leakage from entering the test chamber. The core problem in the production process is the quality problem of many rejects and the quantity not yet meeting the production target. The observation results show that the gasket reject problem is found in the four holes that are formed, which do not match the dimensions or are torn. Making four holes in the gasket made from neoprene rubber is done through a drilling process, which can risk tearing or damage. The type of drill bit used can affect the success of drilling gasket holes. The process of making four holes in the gasket using the piercing method is thought to be able to increase the quality and quantity of gasket products. This research aims to increase the quantity and quality of Ge Nose 19 medical device gaskets using a piercing tool. Research methods include problem identification, literature study, design, manufacture, and testing of piercing tools. The test parameters are time and product quality, namely the shape and position of the hole. The results of this research show a reduction in the cycle time of the hole-making process by 53.7%, so production capacity has increased by 51.8%. The quality of gasket production has increased; of the 40 samples tested, 0 gaskets were rejected.

“…Compared with other clinching processes, the strength of dieless clinched joints is lower [10]. Thus, Chen et al [29] compare the failure mechanism of the dieless clinched joints of various aluminum alloys, protrusion heights of the AL5052 joint, AL5182 joint, and AL6061 joint are 1.08 mm, 1.17 mm, and 1.20 mm, the protrusion height is faintly affected by the sheet materials. The protrusion height of the traditional dieless clinching joint mainly depends on the blank holder, the gap between the upper and lower sheets is obvious, and the protrusion height is between 0.33 mm to 1 mm, using a compressed method, the protrusion height can be reduced from 1.62 to 0.94 mm [30].…”

The low strength and large protrusion of the traditional dieless clinched joint hindered its application. To improve the mechanical properties of the dieless clinched joint, a novel dieless clinching process considering the limitation of the blank holder was proposed. The finite element model of the dieless clinching process was established by DEFORM-2D, the influences of the blank holder spring stiffness, the blank holder limit height, and the punch diameter on the mechanical interlock of the joint were analyzed, and the influence laws of blank holder spring stiffness and blank holder limit height on material flow and mechanical interlock were obtained. Then, the influence of these three die parameters and their interaction on the joint interlock were analyzed using the response surface method. The results show that the blank holder displacement plays a key role in the formation of mechanical interlock in the dieless clinching process. Reasonable limit height and spring stiffness of the blank holder can control the flow direction of materials, so as to improve the mechanical interlock and the strength of dieless clinched joints. It provides a new idea for improving the dieless clinching process.

“…Currently, aluminum is a non-ferrous metal that is most widely used in many branches of industry because of its superior and superior properties, especially Aluminum-silicon (Al-Si) alloys. In its development, Aluminum-silicon is widely used as a material for making a product because it has excellent castability, good weldability, good thermal conductivity, high strength at high temperatures, and excellent corrosion resistance [1][2][3][4][5][6].…”

This study aims to determine the effect of the heat treatment process and pressing on hardness, density, and morphological changes in the microstructure of Al-Si alloys. In this study, the medium used was coconut shell charcoal with a mesh size of 80 at a heat treatment process of 400 °C and a holding time of 75 minutes. The pressing was carried out with a load of 150 N. The result of this research is an increase in the hardness of the Al-Si alloy with an average value of 133 VHN after the Heat Treatment and pressing process. In the microstructure, there is a morphological change in the Al-Si alloy with the reduction of Si elements and also an increase in the density value after the heat treatment process.
