Die casting, types and components

  1. 1. Precision Machined Component Die Casting, Types and Components Casting is one of the oldest procedures performed on metals. Many products are formed using this method. Here is an attempt to share the knowledge of the casting. Casting is one of four types: sand casting, permanent molding, casting and casting plaster. All these types of castings have their own advantages and disadvantages. Depending on the properties of the product corresponded, select one of the casting. Sand Casting: Sand casting is the oldest cast earlier. This method of casting is in use since 1950.The product texture depends on the sand used for casting. The final product is given a smooth finish on the end. Usually iron, steel, bronze, brass, aluminum, magnesium alloys often including lead, tin and zinc are used. Permanent mold casting: permanent mold casting two piece molds. These molds are joined together and the molten metal is poured into the mold. The hot metal is cooled and the mold parts are separated. Some products have metal extrusion are removed by grinding or flash hand. Tin, lead and zinc are commonly molded with this method. Casting Plaster: plaster casting is one of the easiest methods. However used for metals low melting point as Copper, Zinc and Aluminum. This is the easiest process because mold can be easily done if the brakes on the proceedings. Die Casting: Die casting is done by introducing molten metal into the mold under high or low pressure. Previously only used molded under pressure, but now a day of high pressure castings used more widely. The molds are well designed to give complex products with impressive accuracy and smooth finish. Are made of high quality steel such as steel has a higher melting point. These molds can be reused thousands of times. The molds can be of a single cavity that produces only a single component, multiple cavities that produces multiple identical parts simultaneously, the die unit that produces different parts and die combination to produce different parts of a single time. Usually, zinc, copper, aluminum, magnesium, lead, tin and tin -based alloys are used for die casting. The use of casting can make products with pores free products that do not allow gas to pass through them and make them strong. Two types of machines are used for casting. Cold chamber and hot chamber casting.
  2. 2. Hot- chamber die casting metal is used for high fluidity. First, the molten metal is collected using gooseneck metal and then shot him in the mold. The advantage of this method is the cycles / min increased. But the disadvantage is that the metals of high melting point and aluminum - iron particles collect SUP. Die casting cold chamber is used when you cannot use hot chamber. In this process, molten metal is transferred to the injector nozzle and then inject the metal into the mold. Metals with higher melting points can be die cast by this process but the downside is that it is slow hot chamber process.
