Review Article OPTIMIZATION IN GREEN SAND CASTING

2014-2-20 This paper extensively reviews published research on green sand casting process. The effects of riser design, gating system, moulding sand, oxidation and deformation of casting during heat treatment, machining allowance, etc., on the economical manufacture quality castings were reviewed. Determining the optimal process parameter setting will

[PDF] Application of Six Sigma Method to Reduce Defects

Six Sigma is statistical and scientific methods to reduce the defect rates and achieve improved quality. A case study carried out for a green sand casting manufacturing industry. Here Six Sigma methodology is used for the part: Transmission Case. DMAIC (Define–Measure–Analyse–Improve–Control) methodology along with Taguchi method is used to minimize the defects in the Transmission Case.

Application of Six-Sigma DMAIC methodology to sand

2013-6-20 This paper deals with the application of Six-Sigma methodology to the flywheel casting process in foundry to minimize the defects in this process. The primary tools used in this interventionist process were the process map, cause-and-effect matrix and the failure mode effective analysis. The present study proposes to measure the performance criteria of the process through investigating the
