The Metals to Use for Die Casting. The #1 most abundant metal on earth is aluminum. Then there is iron, magnesium, calcium, and the rest. Aluminum is a widely used metal. Ever since the discovery of electrolysis to extract it from ores made it affordable and practical. Before that discovery in the 19th century, this metal was more expensive than gold and silver. The reason for this unusual phenomenon was that aluminum, though abundant, was hard to produce and therefore expensive to produce. Nowadays, it is a lot cheaper and used in a lot of different applications. Aside from such diverse functions as high-voltage electric lines, food containers, and mirror coatings, this silver grey metal zinc alloy is also in airplanes and automobiles, marine outboard motors, escalators, guitar amplifiers, light fixtures, and typewriters as aluminum cast parts.

The Casting methods for aluminum can be chosen depending on what they are to be used for. The metal is so adaptable that it can be shaped or cast using all the processes known to metal. The aluminum casting process is as diverse as the metal’s many applications. Although in pure form it is soft, its alloy is quite hard. The metals suitable to make aluminum alloys are zinc alloy, copper, manganese, and magnesium.

Also, Aluminum part castings use a number of metallurgical casting methods. The molten aluminum is poured into a mold. The mold could be made of sand, plaster, wax, or a stronger metal. These molds are pre-shaped into the desired product. They are strong enough to withstand multiple castings. The different processes of casting are called die casting, sand casting, investment casting or the lost wax process, and continuous casting.

Benefits of Aluminum Metals and the Zinc Diecasting Method

Filed under: Aluminum Cast Parts Alloys — Tags: , , , , — admin @ 1:33 am

Benefits of Aluminum Metals and the Zinc Diecasting Method. Aluminum die casting process have been used in metalworking as early as 1914. The aluminum metal has since been one of the metals usually favored by many manufacturers due to its inherent properties. The other metal alloys that are in use today include lead, tin, copper and magnesium. Each of these metals are employed due to their intrinsic diecasting characteristics.

Among all these alloys, zinc is the metal alloy that is easiest to cast compared to the other metals utilized in the casting industry today. Other qualities such as great impact strength and ductility make it very useful. This metal alloy can also be plated rather easily and producing small diecasting parts simply a breeze. Because of its low melting point, the die’s service life is lengthened since it isn’t subject to a lot of intense heat.

History of Zinc Diecasting

Casting as a process used in the metalworking industry has been around for centuries. The technology of pressure injection die casting and gravity pressure casting has been around since the middle of the eighteenth century. The first patent to be issued for such a technology was awarded to Sturges in the year 1849. This was in line with the invention of the diecasting machine used to manufacture printing types.

For the next two decades, castings were produced only for the movable type used in printing. Other developments with this technology ensued some time after. Other shapes were experimented on and in 1892 a lot of commercial applications were then included and eventually manufactured. This casting technology made it possible for industry leaders to mass produce various die casting parts for cash registers and phonographs among many other things.

Importantly also the casting metal alloys that were employed in metalworking back in the early days incorporated lead and tin in a variety of compositions. In 1914 aluminum and zinc alloys were introduced and were favored because of the advantageous characteristics of these two metals. The other popular metal alloys used to this day followed several years later, which includes copper and magnesium.

Similarly, the casting process along with other specific procedures like Aluminum casting underwent an evolution. The diecasting metalworking industry initially used low pressure injection. Other casting methods and processes were introduced later including high pressure diecasting, semi solid casting, and squeeze die casting. As the technology improved the ensuing output obtained better surface finishes, high integrity, and near net shape properties.

Zinc die casting process and other diecasting processes will continue to evolve. A lot of refinements in the currently used production processes will still be made. A huge amount of research is also put into the development of the die casting alloys being used in the industry. The goal in this research and development drive is to expand the number of diecasting applications for the manufactured products and eventually enter other possible markets.

Imagine, the initial applications were just for very simple lead types, which are fairly easy to produce. Nowadays, die casters are able to mass produce a lot of intricate casting parts for automobiles, toys, and other intricate materials. The advancement in zinc www.cast-parts.com technology has made it possible to create dimensionally precise diecasting parts and a lot is expected in the near future.

Zinc Die Casting Manufacturing Technique and Related Attributes. Aluminum die cast manufacturing is one of the many known metal casting processes being utilized in the metalworking industry today. Other than zinc, other alloys use other materials as well, which includes the following – lead and magnesium. Each of these casting metals has its own unique attributes that make them pretty useful.

For instance, among these said metals, magnesium is the one that is easiest to machine and it has a pretty good ratio between its weight and strength. On the other hand zinc is very easy to cast. It also has high impact strength and is really cost saving when manufacturing small parts.

Zinc Die Casting Metal Working Technique and Related Attributes

The technique of metal die casting involves injecting liquefied molten metal into steel molds that are otherwise known as die cast tooling. Certain characteristics of aluminum alloy make it well suited for certain uses. First off, this metal alloy is corrosion resistant unlike iron that is prone to rust and quick decay. The materials that are created using aluminum metal tend to be lightweight and easier to transport.

There are other characteristics of aluminum alloys that make them very useful. Its high dimensional stability works very well for manufacturing thin walls and very complex figures. It also has great mechanical properties and it can remain very sturdy in spite of high temperatures. This metal alloy is also a good conductor of electricity and heat.

Accepted as the traditional method of aluminum die casting manufacturing is also called high pressure diecast manufacturing. This method of diecast manufacturing has four consecutive steps – die preparation, filling, ejection, and finally shakeout. The preparation stage incorporates spraying lubricant into the cavity of the die, which helps make it easier to remove the aluminum metal. Lubrication also helps in temperature control.

After the die is lubricated and prepared, molten aluminum alloy is injected into the enclosure using very high pressure, which is where the name of this method was taken. The pressure in the die usually ranges from 1,500 psi to 25,400 psi, which is maintained until the metal alloy solidifies.

Once the alloy inside have solidified then the dies are opened and the shot is ejected. The final step in the traditional method of aluminum die cast manufacturing is called the shakeout, simply because the scraps are removed or shaken off the casting. Manufacturers utilize a trimming die that is mounted on a power or a hydraulic press in the final step in the entire process.

Better or Worse – Therefore a huge amount of pressure is used to fill the die, the cavity that needs to be filled by the cast is easily filled before any part or portion of the molten metal solidifies. This basically solves the initial problem of discontinuity in the casting. The drawback to this method is that air gets entrapped pretty easily thus producing small pockets or pores.

Regarding the amount of porosity in the center of the cast alloy part, vents are incorporated into the die. These vents are usually placed along the parting lines. Other finishing processes such as plating, hole-tapping, and buffing are utilized in order to obtain the best output in Aluminum die casting manufacturing.

Helpful Information to Know About Metal Die Castings

Filed under: Cast Parts — Tags: , , , , — admin @ 1:12 am

Helpful Information to Know About Metal Die Castings. In today’s marketplace, it is very ordinary to see parts containing materials made from die castings. From lighting fixtures to vehicle parts, die casting has something to offer. Be it simple, tiny parts or big, complex accessories, die casting can mold thousands of stuff made from metal and other applicable materials distributed commercially and industrially.

Do you know about Aluminum Parts Die Casting Production? Die casting is a metal forming process that injects metal into a strong, high-pressured steel mold or die producing accurately engineered metal parts. This process solidifies the molten metal quickly. As soon as the metal hardens, the part is ejected from the die. Die casting is almost the same as permanent mold casting with outcomes characterized by precise dimensions, sharp definition, and high repeatability. It is a versatile process enabling the manufacture of a wide range of durable finishes.

The roots of Aluminum Die Casting Parts Production. In 1838, the first manually-operated die casting machine was invented for the purpose of manufacturing movable type for printers. The first patent of this model was given to Sturges in 1849 for mechanized printing type production. For almost twenty years, this die cast equipment was solely used to make printer types. But by the end of the century, several commercial applications for die cast were discovered, namely: parts for cash registers and phonographs among others. Since then, many other types of equipment for die castings were made to produce various metal tools such as die casting tooling.

Die Casting Equipment. There are two types of machines used for die casting: the hot chamber machine and cold chamber machine. Hot chamber machines, also known as gooseneck machines, normally process metals such as copper, lead, zinc, magnesium, and other low melting point materials that work well with metal pots, plungers, and cylinders. It has a compartment which contains molten metal. This molten metal is then poured towards the furnace through a connecting metal called a gooseneck. Once the molten metal fills the gooseneck, the piston pushes the metal into the die. Cold chamber machines, on the other hand, processes high melting point alloys such as aluminum and others. Here, the molten metal is dispensed to a cylindrical sleeve, or a cold chamber using a manual or automatic hand ladle. The hydraulic plunger shoves the metal into the locked die at a very high pressure.

Alloys Used for Die Casting Production. Die castings make use of non-ferrous or non-iron materials such as zinc, aluminum, magnesium, copper, lead, tin, and bronze. It is also reasonable to die cast iron but it is an infrequent practice.

Zinc alloy: Zinc is very ductile and perhaps the easiest metal to cast and plate. It is highly recommended for small parts and promotes long die life. This is called the zinc die casting process

Copper alloy: Copper is a strong metal with very high wear and corrosion resistance. Among other metals, it exhibits excellent dimensional stability and mechanical properties of alloys.

Aluminum : Aluminum has good mechanical properties and corrosion resistance. It exhibits high thermal and electrical conductivity making it resilient to extremely high temperatures. It is perfect for making thin walls and complex shapes.
