5 Key Characteristics of High Quality Parts for a Magnesium Die Casting Machine
The use of high quality parts for Magnesium machining is critical to efficiency and economic benefits of magnesium casting. Die casting continues to offer numerous advantages for developers and designers which are unparalleled by other manufacturing processes. It provides the ability to create complex shapes within narrow tolerance levels while minimizing the need for retooling. The use of high quality parts is particularly important when it comes to Goosenecks and crucibles (melting & holding pots). There are five key characteristics which all high quality magnesium casting machine parts have in common.
Minimize Expansion and Contraction in High Temperatures
The first characteristic is related to expansion and contraction in high temperatures. Only high quality goosenecks and melting pots have the ability to minimize expansion and contraction at high temperatures. This is critical to guarantee against casting defects which are common when lower quality parts are used. A key benefit of magnesium casting machines is the ability to accurately create identical complex shapes. This can only be achieved if the gooseneck and melting pot do not expand and contract as temperatures change.
Abrasion resistance is an equally important characteristic of high quality hot chamber magnesium die machine parts. By minimizing abrasion the properties of materials used in the creation process are maintained. It ensures the materials used to create the gooseneck and crucible do not slowly seep or flake into the product being made. Additionally, the lack of abrasion resistance significantly increases the risk that oxides will be generated through the magnesium alloy melting process, thus diluting the purity of the finished product.
Shock resistance is often overlooked as a key characteristic of high quality magnesium die casting machine parts. Shock resistance is particularly important for goosenecks and melting pots as these parts are put under tremendous strain during the casting process. The shock resistance characteristic ensures a long lifespan for the most critical parts of the die machine.
Erosion resistance and shock resistance work hand-in-hand. Throughout the die casting process there are numerous opportunities for key components to slowly erode. Not only does this dilute the purity of the finished process but also shortens the lifespan of individual parts. Low-quality parts quickly undermine the reliability and consistency of a magnesium die casting machine.
Internal Design Consistency
The internal design consistency of a melting pot is important but it is even more important for goosenecks. Internal design consistency is what allows the magnesium die casting process to efficiently and economically generate thousands of copies of a single complex shape with minimal variance. A lack of internal design consistency can also lead to premature wear and tear on individual parts.
