Zinc Die Cast – The Die Cast Tooling Process. If you hear someone say the phrases like “insert dies”, “Zinc Die Casting Molds” or “Zinc Die Casting Dies,” that person is referring to the Zinc Die Casting Tooling. It has various styles, sizes, and forms and it either comes with one cavity or numerous cavities.
Zinc Die Casting Tooling is built of metal tool alloys separated into 2 parts, which are the ejector-die half and the fixed-die half. Newer version of dies may possibly have movable cores, slides or further sections in order to create threads, holes, and other preferred contours. The sprue holes placed in fixed-die half, directs the molten metal through the die until the cavity becomes full. Typically, the ejector-die half is composed of inlets and passageways that guide the molten metal through the cavity. The dies have holes for cooling fluid agent and grease, locking pins for the security of the pair of halves and ejector pins to help eliminate the cast part in the equipment.
Every so often, zinc parts require trim tooling. As soon as a zinc part is created by the Zinc Die Casting Tooling machine, the extra zinc surrounding the parts of the zinc will be cleaned by the trim die tool. The die is placed into the trim press wherein the ejector-die half and fixed-die half are put on hydraulic pressure so that it will be easier to sheer and trim the materials all together. With the use of trim dies the production process of zinc part is faster. As a result, at least 15% in the cost of the zinc part is saved.
