The Hot air producing Oven is used to heat the sleeves which are used as raiser in casting purpose. The sleeves that
are being manufactured are made of epoxy resin which consists of approximately 75% water and 25% mineral mix before
heating and once the processes are complete i.e. the sleeves getting heated in the oven the product would turn into 35% water +
65% mix. The whole process would estimate the time around 4.5 hours. The first 2.5 hours the water is being removed from the
sleeves in form of latent heat vaporization. The next 2 hours is use as the time for curing the them because of the flow of hot air
through the sleeves.
