Abstract
This paper investigates how various process settings influence critical outcomes in the manufacturing of plastic micro needles. By improving the reliability and accuracy of micro needle fabrication, the work has implications for various fields, including biomedical devices, drug delivery systems, and microfluidics.
Investigating factors such as melt temperature, mold temperature, injection speed, packing pressure, and velocity-to-pressure (V/P) switchover point, will allow us to understand their impact on the key characteristics like the needle size, and the tip diameter of the needles.
Using Design of Experiments (DOE) and analyzing extensive data sets, we uncover insights into the complex relationship between process parameters and desired objectives. Our findings offer practical guidance for optimizing the manufacturing process to achieve higher quality and consistency in micro manufacturing, and specifically, in micro needle production.
Micro injection molding technology is very challenging in terms of tool and process set up. Also, with a very slight error in the process, there might be a need to unmount the tool and extensive cleaning which might take hours and reduces the process efficiency. So, the importance of having an optimized process condition becomes clear.
Overall, this research contributes to the ongoing efforts in precision engineering by offering practical solutions and insights for practitioners. In addition, highlights the importance of understanding and optimizing production settings in the manufacturing of plastic micro needles, with broader implications for precision engineering and related industries.
