Aluminum Casting Laboratory To Develop Competencies of Vocational High School Teacher Candidate

Aluminum casting laboratory model was developed in order to build competencies of Vocational High School (VHS) teacher candidates of mechanical engineering program. Research and development method was used to develop the model which consist steps of: need assessment, model design, preparing tools and equipment, application, evaluation and dissemination. The model verification involving respondent from metal casting industry, Manufacture Polytechnic of Bandung and VHS which is conduct casting program. The model of aluminum casting laboratory was designed integratedly with materials and processing laboratory. Equipment and tools should be prepared for melting process, pattern making, core and sand mold making, cutting and cleaning casting product, work and health safety also foundry and mold material. The crucible furnace developed to melt the aluminum is LPG-fueled one, having 20 kg capacity and using spiral finned crucible pot.
