INVESTIGATIONS FOR STATISTICALLY CONTROLLED INVESTMENT CASTING SOLUTION USING ABS REPLICAS By Gurwinder Singh,Production


Abstract
Fused deposition modeling (FDM) is one of the prototyping technique in which parts can be produced rapidly and accurately. Investment casting is an established process for producing components with high precision and accuracy. The purpose of the present study is to investigate the statistically controlled ABS replica as investment casting rapid casting solution. This study highlights the process of FDM + Investment casting as rapid casting solution. The work started with the identification of the benchmark/component. Prototypes (to be used as pattern) were built on FDM with ABS plastic material, followed by investment casting. The measurements on final casting prepared were made on the co-ordinate measuring machine from which IT grades were calculated to establish the dimensional accuracy of the castings (as per industrial standards). Measured mechanical properties (like: hardness, surface finish) indicated further suitability of this process. Final castings produced are acceptable as per ISO standard UNI EN 20286-I (1995).This process ensures FDM and investment casting of pre-series technological prototypes and proof of concept at less production cost and time.
