The other alloys can only be used after reviewing the part geometry and performing an FEA analysis of the casting process. Our team of experts can help select the best alloys for your castings
Aluminum HPDC High Pressure Die Casting is a metal casting process that is characterized by forcing molten aluminum metal alloy under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similar to a conventional plastic injection mold during the process.
Hot Chamber Die Casting The hot chamber process is used extensively for casting of smaller magnesium parts with shot weights up to 2-3 kilograms. This process is not used for aluminium parts. Static metal pressures are usually less than in cold chamber machines,typically in the range of 20-30 MPa 2900-4400 psi.
Schematic DC casting process used for magnesium billet casting Mathematical modeling of the DC casting process using various techniques has been underway since 1940 2. The earliest published mathematical model of DC casting using a computer to solve the heat conduction equation numerically was published by Adenis et al.
The new process - the low pressure lost foam casting process Figure 1 for magnesium alloys represents an innovative technology which takes advantage of the benefits of hoth gravity lost foam casting and low - pressure casting.As a result of the applied pressure the molten metal rises up an ascension pipe to fill from below the binderless silica sand mould, the cavity of which is filled by a ...
Magnesium Alloy Die Casting is a kind of magnesium alloy based on magnesium and alloying elements, which is suitable for casting parts. According to the forming process, magnesium alloy can be divided into cast magnesium alloy and wrought magnesium alloy.

Jan 06, 2020 Magnesium Casting Metals Magnesium is strong, rigid, fully recyclable, and is the ideal alloy for saving weight when you dont want to sacrifice durability. Looking for lightweight die castings Talk to our engineering team about utilizing magnesium. Advantages of Magnesium Die Castings. There are many benefits to casting with magnesium.
Rapid magnesium castings can be produced by plaster casting within only 1-2 weeks. Suitable for complex parts in smaller quantities in the early development phase. High pressure die casting prototypes produced in soft tools within 4-8 weeks. Suitable for higher prototype quantities. Prototypes machined from cast magnesium blocks within 2-5 weeks.
May 19, 2021 The cost of Magnesium die casting process includes labor cost, equipment cost, and is also affected by working efficiency. Compared with die casting with zinc alloys and aluminum alloys, magnesium dies casting machines are more expensive in the condition of the same die-casting parameters, for the higher costs of their furnace systems, die ...
The inmold method is a special process in that the master alloy with a low magnesium content is positioned in a reaction chamber directly in the casting mold and that the poured iron with a particularly low sulfur content reacts with the master alloy inside the mold.
Magnesium Die Casting. Casting is a process in which molten metal is poured into a mould that contains the intended shape. High pressure die casting HPDC is the most common method of Magnesium Die Casting and its alloys.. Magnesium is melted at a temperature of 923K and poured into crucibles where it is cooled under high pressure.
Ductile iron casting refers to a process in which magnesium cerium as an alloy of magnesium cerium is added to cast iron. It reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed. Ductile cast iron also called as spheroidal graphite cast iron or nodular cast iron has been widely used as a main industrial material in place of high-grade cast iron.

High Specific Strength When alloyed, Magnesium has the highest strength-to-weight ratio of all structural metals. Faster production Cycle Magnesium alloys have low heat content, which means lower casting temperature is required and a faster cooling process. Therefore, the production rate is 75 higher than that of aluminum casting.
The steps in casting molten metal consist of preparing the mold or die, melting the metal, melt processing to remove sources of defects and to modify, refine, or otherwise adjust the chemistry of the alloy, pouring or forcing the melt into the mold or die, solidification and removal of the casting. Casting is a very complex process and even the briefest introduction to its theory and practice is beyond the
