DESIGN AND SIMULATION OF POLYMER NEEDLES TO PRODUCE BY INJECTION MOLDING MACHINE

Abstract

This paper study the production of small Needles by using Polymer materials. Ferro materials are commonly used, due to good mechanical properties, stainless steel is preferred for medical use, because it has high corrosion resistance and also a commonly used for medical application, but it is expensive and hard to clean for multiple use. The objective of this paper is to make simple, cheap, and one time use arrays of small scale solid polymer needles for health and beauty use. Micro injection molding process is the key technology for manufacturing polymeric parts with structure dimensions in micron and sub-micron range. In this paper A selected needle model was simulated via the results of suffered and strength analysis, and the array of needles was simulated with five different polymer materials (PS,PP,PLA,PC,ABS) by Mold Flow Analysis to make the right product with  the suitable injection mold for the Micro Injection Molding machine
