  • Microforming for the production of microscale components: A study on the effect of forming dies in microextrusion of metals

    Journal of Micromanufacturing, 2026
    Micro products play a critical role in various fields, ranging from consumer electronics like watches and cell phones to advanced medical devices. These intricate parts cannot be manufactured using conventional methods, making microforming a viable solution for producing such components. The goal of the current study is to examine how various forming die conditions affect the production of microparts, namely through the metal microextrusion method. Three distinct die conditions were evaluated: dry die condition, lubricated die condition, and diamond-like carbon (DLC) coated die condition. To demonstrate the practical aspects of microforming, two different metals were employed in the study, with a micropin chosen as the representative micropart for investigation. During the microextrusion tests, various parameters were recorded, including force-displacement response, hardness, and surface roughness of the microextrudates. In comparison to uncoated and lubricated dies, the results show that using a DLC-coated die greatly decreased the extrusion force and enhanced the micropins’ surface polish. Additionally, the greatest pin length produced by the DLC-coated die was 7.9 and 12.7 mm for Cu and Al billets, while the uncoated die yielded a shorter pin length of 5.2 and 7.6 mm. However, the hardness of the microextrudates was found to be higher with the uncoated die, showing a trade-off between surface finish and material hardness.

  • Numerical simulation of microextrusion: influence of die entry angles and friction on deformation behavior of AA6063 aluminum alloy

    Revista Materia, 2025
    Micro/meso fabrication techniques have gained significant recognition globally for their advanced manufacturing capabilities. Among these, microforming stands out as a leading process in micromanufacturing. Despite growing interest in microextrusion for industrial applications, the technology remains underdeveloped compared to conventional forming methods, with limited expertise available. To address this gap, it is essential to develop a comprehensive understanding of the microextrusion process, which can guide the production of metallic microcomponents. This research focuses on the numerical simulation of microextrusion to study the influence of die entry angles on the deformation behavior of AA6063 aluminum alloy. Simulations were conducted using die angles of 15°, 30°, 45°, and 60° under varying frictional conditions. Results show a direct relationship between die angle and forming load, while punch displacement decreases as the die angle increases. The role of friction was also found to be crucial in the extrusion process. Numerical results for the 30° die angle were compared with experimental data, highlighting the effectiveness of finite element analysis in predicting microforming outcomes. This study demonstrates the potential of numerical simulation as a powerful tool for optimizing microforming processes in industrial applications.
  • Experimental investigations of influence on grain size and cold deformational behavior of AL6063 during the microforming process

    Miniature products are requisite to make micro creation widely in electronics and micromechanical products. The microfabrication process is identified to satisfy the production of such miniature products rather than an ordinary manufacturing process. Microextrusion is one of the microforming processes in micromanufacturing. In this present work, an attempt has been made to investigate the influence of grain size and deformation behavior of Al6063 microstepped pin with annealed billets for the cold extrusion process. The methodology on the characterization of the microextrusion of Al6063 includes, annealing of the billet, extrusion testing, microhardness examination and surface roughness analysis. The billet with three different sizes of grains is extruded. The experimental result shows that the deformation load and average microhardness of the AA96 (annealed Al6063 with an obtained grain size of 96 μm) are high compared to AA208 (annealed Al6063 with an obtained grain size of 208 μm). The surface finish has improved using diamond-like carbon (DLC) coated die compared to uncoated and lubricated dies. DLC coating with AA208 billet achieved a maximum pin length of 13.1 mm, and uncoated die with AA96 billet achieved a minimum pin length of 5.5 mm. Thus, the findings of this study contribute to the fundamental understanding of cold microextrusion of aluminium 6063 alloy.
