Die Casting Companies produce several parts from magnesium. The demand driven by magnesium’s lower weight than other materials, fuels the demand for magnesium automobile parts. The second most common application for die casting magnesium is electronic devices. Due to low weight, good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop computers, cameras, and other electronic components using magnesium die casting.

Historically, magnesium was one of the main aerospace construction metals and was used for German military aircraft as early as World War I and extensively for German aircraft in World War II. The Germans coined the name ‘Elektron’ for magnesium alloy which is still used today. Due to perceived hazards with magnesium parts in the event of fire, the application of magnesium in the commercial aerospace industry was generally restricted to engine related components. Currently the use of magnesium alloys in aerospace is increasing, mostly driven by the increasing importance of fuel economy and the need to reduce weight. The development and testing of new magnesium alloys continues, notably Elektron 21 which has successfully undergone extensive aerospace testing for suitability in engine, internal and airframe components. The European Community runs three R&D magnesium projects in the Aerospace priority of Six Framework Program. Only recently has magnesium been used in magnesium die castings by die casting companies.

Incendiary use: Magnesium is flammable, burning at a temperature of approximately 2500 K (2200 °C, 4000 °F), and the autoignition temperature of magnesium is approximately 744 K (473 °C, 883 °F) in air. The extremely high temperature at which magnesium burns makes it a handy tool for starting emergency fires during outdoor recreation. Other related uses include flashlight photography, flares, pyrotechnics, fireworks sparklers, and incendiary bombs.

Magnesium die casting metal and its alloys are explosive hazards; they are highly flammable in their pure form when molten or in powder or in ribbon form. Burning or molten magnesium metal reacts violently with water. When working with powdered magnesium, safety glasses with welding eye protection are employed, because the bright white light produced by burning magnesium contains ultraviolet light that can permanently damage the retinas of the eyes.

The Role of Zinc Die Casting Tooling. Zinc parts are produced with the zinc die casting tooling in the zinc die casting machine. The components of the zinc die casting, as well as the zinc dies are alloy tool steels that are divided into two parts. These 2 parts are the ejector die half and the fixed die half, which permit the removal of the castings from the die casting machine. Modern dies may include cores, movable slides or other portions that can produce threads, holes, and shapes as may be required in casting. The sprue holes in fixed die half permit molten metal into the die and fill the cavity. Dies also have the locking pins that serve to secure the two halves. It also includes ejector pins that help in taking out the cast parts and openings for lubricant and coolant.

When the machine for die casting shuts off, the 2 die halves will be held together and locked by the hydraulic pressure of the zinc machine. The die parting line is the machine’s surface wherein the meeting and locking of the ejector as well as the fixed halves happens. The total area of the part’s surface being die casted, the pressure and the die parting line’s measurement needed in injecting metal to the cavity’s die manages to determine the machine’s clamping force.

What people refer to as those die casting molds and insert dies made of zinc are what is referred to as zinc die casting tooling. This tooling is available in various styles, shapes, and sizes. It comes in either 1 or more cavities. Zinc die cast tools varies due to cavity inserts as well as trim dies.

Tooling for Zinc Die Cast Parts. The process of making of die cast parts entails value for product quality, above else. With this in mind, zinc die casters tend to give premium on following specifications right to the tilt. The basic agenda on the list is zinc tooling die construction, which is primarily made of zinc die casting tooling. Die casting is made of alloy tool steels in at least two sections, namely the fixed die half and the tooling ejector die half. In modern times, tooling dies may carry cores, movable slides, or other sections for the production of threads, holes, and other features for the attainment of the desired shapes.

The fixed die tooling half has sprue holes that makes it possible for the molten metal to enter the die and fill in the tool cavity. On the other hand, the tooling ejector die half has runners and gates that lead the molten metal right into the cavity. Aside from these two sections involved in the die casting zinc process, tooling dies also consist of locking pins (for purposes of securing the fixed die half and the ejector die half), tooling ejector pins (for purposes of making the removal of the cast zinc part easier), and openings (for purposes of cooling and lubricating the molten zinc metal or cast).

When the hot chamber tooling die closes, the fixed die half and the ejector die half become one and remain locked together, thanks to the hot chamber machine’s hydraulic pressure. After a certain amount of time elapses (depending on the total projected surface area and the pressure required for the injection of the metal into the cavity), the zinc die casting process is completed and high quality die casting zinc parts are produced.

Die casting zinc beautiful. From forcing molten metal zinc under high pressure into mold cavities, products from and for zinc die casting are formed. Die casting zinc, as we know it, is one fine way to produce small to medium sized zinc parts that has good and intricate details, delicately formed surfaces, and that has consistency in dimensions making it as a very welcome addition in the production industry.

Now, some of you may wonder what materials are used in this very clever process. With die casting, raw materials and elements (or non-ferrous metals as they are properly called) like zinc, copper, aluminum, magnesium, lead, and tin based alloys are used. These non-ferrous metals, as their collective name suggests, contains no trace of iron. And although these are the materials that are commonly used, ferrous materials (or materials that has traces of iron) can also be used in this process.

And the process itself, you may ask? Well, die casting zinc begins with closing the mold after being sprayed with a lubricant. By spraying lubricant on the mold, the temperature of the die can easily be controlled and the removing the zinc casting later on will be much easier. After this first step, using a hot chamber zinc die casting machine, molten zinc metal that is under high pressure of around 10—175 MPa (1,500—25,000 psi) is shot into the die. This amount of pressure is kept once the die is filled and until it is totally solidified. Filling the die by using a high-pressure injection is done so that the whole cavity would be filled before zinc parts of the entire zinc casting hardens. Moreover, using a high-pressure injection helps makers avoid irregularities in form even if there are parts of the zinc casting that are not easy to fill due to its irregular shape.

And with a Hot Chamber Zinc process as long as this one, one can be sure that the results will be beautiful die casting zinc parts.
