Abstract
Metal injection moulding (MIM) is large scale manufacturing method, for creation of complex shapes and miniature parts by a
combination of plastic injection moulding with the flexibility in sintering of metal particulates. In current investigation binder
comprised of paraffin wax, polyethylene glycol, stearic acid and low-density polyethylene are developed for moulding of
composite powders of SS316L+WC-CrC-Ni, and sintered at 1200°C under hydrogen purged atmosphere. Composites are
characterised with respect to rheological, thermal properties and microstructure by scanning electron microscopy, microhardness
and density. Properties of sintering temperature and heating rate on the above properties have been evaluated to obtain a defect-
free composite.

1. Introduction
In present trend, the manufacturing process is developed for a large amount of small and complex parts with
increased production rate to full fill demands of various products for modern day to day life. The manufacturing
methods and processing of metal components have general limitations of traditional process for fabrication of metal
components and it encouraging for finding alternative process. Hence alternative method for producing near net
shape metal component is Metal injection moulding (MIM). The MIM is a mishmash of powder metallurgy and
plastic infusion shaping procedure. MIM can produce low-cost products at large number, close tolerance and shape
complexity, good mechanical properties, compare to other technologies since it eliminates secondary operations and
also material damages while in case intricate geometries for numerous applications in today’s industry[1].
