Abstract Pipette tips are used as a research tool related to liquid chemicals. Pipette tips are produced using the injection molding manufacturing process. At PT. Promanufacture Indonesia Salatiga, the transfer of every 96 pipette tips that come out of the injection molding machine is done manually into one caddy within a range of 8-10 minutes. After transfer, the pipette tips continue the printing and filtering manufacturing process. This scientific journal discusses the analysis using the DFMA method in designing an automated machine that shortens the time to insert pipette tips into the caddy within a range of less than 5 minutes. Design for Manufacturing and Assembly (DFMA) is an engineering methodology that focuses on reducing assembly time and total production costs by prioritizing manufacturing ease for product parts and simplified assembly parts into the final product. The machine design previously carried out by the Pahl and Beitz design method. In this journal, DFMA is carried out using the Stack-up tolerance analysis method. With the DFMA analysis of the machine, it will simplify the manufacturing and assembly stages when realizing the machine design. The components analyzed are critical components of the tool referring to the ASME Y14.5-2018 standard. The DFMA analysis in this scientific journal was performed using Solidworks 2021 application accompanied by the steps using the software. The output of the DFMA analysis in this journal is the manufacturability and assembly aspects of the pipette tip refill machine.
