Development of Effective Production Plan for A Sand Mixer

Today manufacturing competitiveness demands the need for cheapest and fastest production process with their goal of safety and quality. In this study, process design of locally fabricated 30 kg capacity sand mixer was developed. The conventional procedure of product analysis;, process identification and selection; and operation determination were performed. A make or buy decision was done based on ease of production or availability of production system. Process determination of the 'Make Parts' was developed based on availability of machinery and cost of materials. The standard time to produce each component part was determined using Metric Time Measurement Standard (MTM) approach. Twenty-one (21) component parts were identified with fourteen (14) being made and seven (7) as bought. Machining and welding are basic manufacturing process to be employed. An effective process and assembly charts were developed. Also an economic production time of 4 hrs 20 minutes per sand mixer was determined. The study provides aan effective production system for economic manufacturing of sand mixer and allied equipment for foundry technology development.
