Cold Chamber Aluminum Die Castings
Cold Chamber Aluminum Die Castings. Die cast methods using aluminum alloy as materials employ machines designed for cold-chamber die castings. Through this cold-chamber method, the material is first melted in a separate furnace. From the molten metal, a precise amount is taken and moved to the cold-chamber machine to be fed into an injection cylinder or an unheated shot chamber. A mechanical or hydraulic piston then drives this shot into the die or mold.
The cold chamber die castings have a relatively slower cycle time compared to the hot chamber method, because of the time required in transferring the molten metal to the cold-chamber machine from the furnace.
Be that as it may, cold chamber aluminum die castings remain as an economical and efficient process. There is a wide range of aluminum parts that could be produced from this method. Long-lived service may be derived from these cold chamber die castings as aluminum is not only light but is also durable and non-corrosive. Mass production of parts at relatively faster speed is likewise possible as the components already come out in their net shapes. Little or no further machining is needed as the cold chamber die castings already roll out in their design specifications. The strength of the aluminum alloy is likewise harnessed to the fullest with designs that need no welding of parts together. And even if there are components that need to be fastened, the dies or molds could incorporate self-fastening holes and studs for a perfect fit of the parts, possibilities that make cold chamber die castings among the valuable tools of modern industry today.
