Most engineers focus heavily on the weight of the material and therefore, Die Casting China is made mostly aluminum, magnesium and zinc. When designing components and selecting the right material is crucial and it is not fair to overlook the qualities zinc has. Many applications require parts to be lighter and especially in automotive and hand held device applications, thus, engineers choose aluminum or magnesium but zinc is mostly a great option and more economical too.
Zinc is the most fluid of all alloys therefore, die castings can be made thinner, more intricate, and more complex. It eliminates the need for secondary operations which is necessary for aluminum and magnesium alloys. With less material being used in thin-wall applications, parts automatically become lighter, creating savings in material cost and energy while melting and recycling.
The tools used in the die casting process are usually heat-treated steel. Due to the low melting temperature of zinc die casting alloy, dies for zinc parts can last up to 10 times longer than dies used for aluminum and 5 times longer than magnesium. Standard zinc alloys are stronger than aluminum and magnesium alloys at room temperature.
During the die casting process, molten metal is injected into the die to create the part. Zinc utilizes the hot chamber die casting process, which yields four to five shots per minute. The metal is solidified and then the material is ejected from the tool. Depending on the alloy and the size of the part, cooling time in the tool varies and it is often dictated by the size of the runner system.
Since cycle time can determine up to 60 percent of the final part cost, using zinc Die Casting China alloy could offer added savings.
We offer you Die Casting made of all the components and alloys of zinc, magnesium and aluminum.
