Die Casting Mold Processes

Filed under: Die Casting Tooling — Tags: , , — admin @ 6:47 pm

Die Casting Mold Processes. Die casting has a similarity to permanent mold casting. The exception is metal is injected into the mold or die casting mold under the high pressure which results to a good surface finish and accurate dimension. Die casting can use cold chamber or hot chamber process.

In a cold chamber process, molten metal is gradually transferred into the cold chamber for every shot. This is useful especially for metals like Aluminum, Copper and its alloys. There is less time exposure of melt to the plunger.

In a hot chamber process, the pressure chamber is connected to the die casting tooling cavity. It is permanently immersed in the molten metal. Pressurizing cylinder inlet port is uncovered as plunger moves to open portion, which allows molten metal into the cavity. This hot chamber is useful for metals of low melting point and high fluidity. Examples are Zinc, Tin and lead that does not alloy easily with the steel.

Die casting molds and tools have a tendency to be expensive because they are produced from hardened steel and has a long cycle time to build. Also, iron and steel are very strong and hard metals and therefore cannot be die cast.

Zinc has high melt fluidity and can therefore be made to close tolerances and with thinner walls than Aluminum. It is alloyed with Aluminum and this makes it hard and strong. Casting is at fairly low temperature (425ºC). Zinc alloys are used to manufacture precision parts like connector housings, sprockets, gears, etc. Copper alloys are useful in electrical, marine and plumbing. They are corrosion and wear resistant.

The process by which molten metal or liquefied metal is poured or inserted into metallic molds at room temperature under pressure, to get desired and particular shape. The molds in which the molten metal is poured are called dies which are generally made up of steel and these dies are patterned accurately to form desired object that do not require touch-up or post-machining. Dies have a great benefit as it can be reused multiple number of times as the temperature of the liquefied metals that is poured in steel dies do not really affect the steel dies. A Zinc Die Casting Company is in great demand recently because of its flexibility because zinc die casting parts can be made conveniently in any desired shape, size and texture mentioned according to the buyer.

A Closer Look into the Casting Process

A Closer Look into the Casting Process. The aluminum casting process has been around for a long time, and it operates by forcing molten metal, which is aluminum (naturally) under considerably high pressure into a variety of tooling cavities. The end result of this process, which actually takes longer than most people think, is a number of aluminum cast parts. Aluminum cast parts are some of the most coveted cast parts in the metalworking industry, and it is not hard to understand why. Aluminum part castings are unbelievably delicate and intricate in form, detail, and texture, allowing clients to make quality products.

So, what actually happens in the aluminum casting process? First things first – the mold is closed, just after it is sprayed with lubricants, and the cast parts are closely monitored in terms of pressure and temperature. The pressure required to shoot the molten metal into the die is around 10-175 mpa or, in other measurements, 1500-25000 psi. This pressure is maintained until, finally, the mold successfully solidifies. To complete the aluminum casting process, the die is then filled with a high-pressure injection; this is repeated before the entire mold gets the chance to harden.

Aluminum is just one of the chosen metals that can be used in the casting process. Other casting process makes use of non-ferrous or ferrous metals (this all depends on the client’s taste and needs), such as tin, magnesium, lead, and zinc. Nevertheless, the aluminum casting process enjoys a vast market and claims one of the top spots in the list of the metalworking industry’s preferred casting processes. Die Cast Tooling.

Better die casting molds

Filed under: Die Casting Tooling — Tags: , — admin @ 4:24 pm

Better die casting tooling from new materials could benefit auto manufacturers. The dies or the die casting molds are expensive parts since these are made from hardened steel. Another reason that contributes to the parts high-price range is the kind of production that is involved in making these die casting tooling molds. The cycle time that is used in building these products is long too. And finally, an important reason why these items are expensive is that the stronger and the harder metals like iron and steel cannot be die-cast. For this reason, these products are highly expensive in the market and this is true for one sector like the automotive industry.

For example, in the auto industry, the traditional die-casting molds that are made from hardened steel and those that are used in making the engine blocks and other auto parts and accessories can reach $500,000 or more. The equipment is pricey and it takes time to build. And this is one issue in the industry that has made some lives of the manufacturers a bit harder. But there is a new breed of materials that is now available in the market that can be used to address this issue. These new batch of materials are materials that can withstand the heat and at the same time not compromising its durability.

According to one researcher, these materials are called the functionally gradient materials. These materials have the capability to shift from one material to the next. And if the future die casting tooling molds are to be created using these materials then the usual cracking expected on the die casting molds can be removed. Plus products like auto parts and accessories made from the molds will have a longer lifespan.

Aluminum Die Casting Parts in Construction

Filed under: Zinc Casting Parts — Tags: , — admin @ 12:12 am

Aluminum die Casting Parts in Construction. Due to the intrinsic characteristics metal alloy parts, aluminum cast parts are widely used up in the construction, ranging from the building’s roof to its walls. Aluminum is known to be malleable, ductile, light-weight, corrosion-resistant, tarnish-resistant, and a conductor of electricity. Aluminum is also a good reflector of visible light, and of medium and far infrared. With all these features of aluminum, the demand for this metal die casting alloy is widespread, ranging from household use to automotive, to engineering, architecture and construction.

Because of its ductility, aluminum cast parts can be shaped up into various forms. Aluminum can be used in building walls, and the use of aluminum would require fewer joints, thus lessening the work needed for the installation. As a light-weight metal, aluminum cast parts are convenient to be used for building structures. This makes it easier for the building to carry its weight rather than being compacted with heavy structures that could even result to the collapsing of the building. Aluminum is even found to be used in the manufacture of glass, ceramic, paints, and varnishes – providing almost everything that is needed in the construction of a brand new building. Aluminum also has a high degree of radiant reflectivity, which means that it has the ability to deflect the sun’s rays; thus, lessening the heat seeping inside the building. Die Casting Tooling.

Aluminum cast parts are recyclable too. This even makes it more desirable to be used. It does not only warrant the cheaper and safer construction of building, what is more is that at the end of the building’s life, its worth does not fall down to zero. The aluminum materials that have been used could still be recycled back to its previous state.
