Numerical Study on The Air Heating for Injection Mold

Injection molding is a popular technology for manufacturing. However, as parts become thinner and maller, they become difficult to manufacture using conventional injection molding, because heat transfers rapidlyom the melt to mold wall due to the thinness of the parts. Increasing the mold temperature, melt temperature, oracking pressure increases the cycle time. At higher mold surface temperatures, the surface quality of the part will improve [1, 2]. In the injection molding field, micro injection molding is being used to manufacture a variety ofolymer components, because of its low cost and potential for high-volume production. Most applications are inthe field of micro optics (such as CDs and DVDs) and micro fluidic devices. Production of other molded microptical components including optical gratings, optical switches and waveguides [3 - 5], and a variety of moldedmicro fluidic devices including pumps, capillary analysis systems and lab-on-a-chip applications [6, 7].
