Capillary rheological studies of 17-4 PH MIM feedstocks prepared using a custom CSIR binder system

Author: Machaka, Ronald ; Ndlangamandla, P ; Seerane, Mandy N Date: Feb 2018 This paper reports on an attempt to establish the rheological properties of 17-4 PH stainless steel MIM feedstocks prepared using a proprietary CSIR wax-based binder system. The influence of powder and feedstock characteristics on the rheological ... Read more
A comparison of different calculations for N-Gram similarities in a spelling corrector for mobile instant messaging language

Author: Butgereit, L ; Botha, RA Date: Oct 2013 Mobile Instant Messaging (MIM) systems have produced a new convention in writing where vowels are often omitted, where new suffixes have appeared, where numerals and symbols often appear in the place of letters which have a similar shape or ...

Determination of optimum thermal debinding and sintering process parameters using Taguchi Method

Author: Seerane, M ; Chikwanda, H ; Machaka, Ronald Date: Jul 2015 Debinding involves long and delicate processing periods of removing binder components from a green body after injection moulding; failure to completely remove the binder components results in distortion, cracking, blisters and contamination ...

The influence of particle size distribution on the properties of metal-injection-moulded 17-4 PH stainless steel

Author: Seerane, Mandy ; Ndlangamandla, P ; Machaka, Ronald Date: Oct 2016 Metal injection moulding (MIM) is a near-net-shaping powder metallurgy technique suitable for the cost-effective mass production of small and complex components. In this paper, the effects of the metal powder particle size on the final ... Read more

Investigation of the powder loading of gas-atomized Ti6Al4V powder using an ‘in-house’ binder for metal injection moulding

Author: Seerane, MN ; Chikwanda, HK ; Focke, W ; Machaka, Ronald Date: Oct 2013 Powder loading is one of the most critical factors in metal injection moulding (MIM) technology. It largely determines the success or failure of the subsequent MIM processes. A gas-atomized Ti6Al4V powder was investigated to determine an ... Read more
A study of solvent debinding variables on Ti6Al4V green bodies

Author: Seerane, M ; Chikwanda, H ; Focke, W ; Machaka, Ronald Date: Oct 2014 Debinding is one of the most critical and time consuming stage in metal injection moulding (MIM). German and Bose (1997) reported that early debinding practice relied on thermal binder degradation, requiring up to 300 hours for complete binder ... Read more
