Pressure Die Casting Aluminum Audio Speaker Parts vs Gravity Casting
Pressure Die Casting Aluminum Audio Speaker Parts vs Gravity Casting. Pressure die casting is a manufacturing process used to create aluminum brackets, parts, chassis, audio speakers and more. These metal parts can be seen almost anywhere and everywhere, making them integral in our day to day lives. Pressure die casting initially melts the aluminum metal. The molten metal is then injected into a mold under great pressure. Afterward, it is set aside to cool for a while. When the Mold is opened, it reveals the finished die casting. Because of this fast and easy process, thousands of parts can be made every day.
Gravity casting uses the similar manner as sand casting. It uses the force of gravity rather than high pressure to fill the mold with the molten aluminum metal. Gravity casting is most fitting for mass production and full mechanized casting. One advantage over gravity casting is that they usually give a better surface finish and mechanical properties, due to its slower cooling rates compared to pressure die casting.
Compared to gravity casting, pressure die casting requires less machining. Die castings can cast holes depending on how and where you want it. Die castings give closer and more accurate dimensions, plus it can be produced at a larger scale, with less labor costs per casting.

Porosity in Die Castings
There are many forms of Die Casting Porosity, many are caused by these die casting variables:
- Metal Temperatures and Mold Temperatures.
- Material Cleanliness.
- Die Casting Mold Design.
- Die Casting Part Design.
- Die Casting Machine Pressures.
- Die Casting Machine Shot Speed.
- Die Casting Spray or Die Casting Mold Release.
- Other forms of porosity can be from “shrinkage” or wall thickness.
What is Die Casting Porosity? In order for you to know what die casting porosity is, you need to know the die casting basics. The most common form of Die Casting Porosity is a kind of factory defect in which die cast parts contain small pockets of void space and air within the metal, causing it to become porous.
Porosity in Die Casting is the air trapped by the metal inside the die casting parts. To know more, a basic knowledge of the die casting process is necessary. Die casting is a process wherein a particular amount of molten metal is put inside a shot cylinder, then it is applied (plunged) with great force with a piston so as to force the metal into a die cast mold or die cast die. During this “plunging process”, air inside the cylinder is forced along with the metal into the die casting mold. It is a very fluid turbulent process. The air forced into the mold with the metal and the metal already inside the mold is forced out of the mold through a series of gates, vents and overflows.
After this, the metal is left to cool down and harden or freeze inside the mold. The metal is then removed as a die cast part. The same process is repeated over again.
Die casting companies use metals which are non-ferrous, or do not contain Iron, as this is the highest factor for oxidation and rusting. Several examples of non-ferrous metals include zinc, aluminum, lead, magnesium, tin and copper. Kinetic Die Casting only uses aluminum and zinc.
In the worst case, porosity in die casting parts, weakens die casting parts, if the voids or pockets are very large. Porosity typically matters most in pressure tight die casting parts. When the air escapes through a die casting part, it is typically caused by porosity.

How Are Aluminum Aircraft Parts Used?
How Are Aluminum Aircraft Parts Used? The popular aircraft airframe has been the most challenging function for aluminum alloys; to account the progress of the high strength alloys is as well to account the progress of airframes. Duralumin is the first high strength, high temperature treatable aluminum alloy and was utilized originally for the structure of stiff airships. Duralumin was actually an aluminum-copper-magnesium alloy. It was initiated in the country of Germany and expanded in the United States of America as alloy 17S-T. It was employed first and foremost as a sheet and plate.
As the 20th century evolved, aluminum turned out to be an important metal in aircraft. The cylinder mass of the engine that controlled the plane of the famous Wright brothers at Kitty Hawk in 1903 was a one piece die casting in an aluminum alloy consisting of 8% copper. The aluminum propeller blades emerged as early as 1907 and aluminum seats, covers, cast brackets, cowlings, and comparable parts were regular by the start of the World War I.
In the year 1916, L. Brequet created a scouting bomber that identified the primary utilization of aluminum in the functioning configuration of a plane. By the end of the war, Germany and the Allies used aluminum alloys intended for the constructional scaffolding of fuselage and section assemblies.

The Advantages of Aluminum Chassis Castings Over Steel
The Advantages of Aluminum Chassis Castings Over Steel. High pressure die casting is the process used to make aluminum die cast parts and chassis castings. This process is now becoming more and more popular in several major manufacturing industries because of its many advantages.
Aluminum is a great metal to work with. Unlike other metals, it has plenty of strengths. The metal can be found almost everywhere in the planet. Supply will not run out, so it is easy to acquire and not heavy on your pockets.
Advantages of aluminum chassis castings over steel include:
- Aluminum can be stronger than steel
- three times greater axial load strength
- Faster production rate. In fact, production quantities can be done within a few days instead of several weeks!
- Fewer failures and returns to the OEM
- Weight is lighter by two and a half times for lesser shipping costs
- Less finishing costs
- Raw parts manufacturing costs are much less
- Better looking parts
You can produce aluminum die casts according to your preference and specifications, such as the trim, clean, machine, inspect, powder coat and the package of your aluminum cast parts.
All in all, the use of aluminum castings over still helps you reduce weight, boost strength, and save you more money.

Why Should You Use Aluminum Military Parts?
Why Should You Use Aluminum Military Parts? Many of the government’s military equipment and weapons are manufactured and made with aluminum parts or die casting parts. There are many advantages when using aluminum to create military parts, and in this article, the most common advantages will be enumerated and explained.
- When forging the military parts using aluminum, the manufacturers are able to produce more complex parts with thinner walls and sections, low finishing costs, and have coring that is normally not feasible in forging. This means that one is able to produce parts that are more difficult than their predecessors but are more tolerable, durable, and of course less costly.
- Aluminum is a more durable, stronger, and more dimensionally stable alloy to use than when using plastic moldings to create military parts. This is because aluminum parts are able to prevent radio frequency, electromagnetic emissions, and other possible effects that could damage the parts. So if you want your military equipment to remain stable and strong despite constant use, this is the kind of alloy and the kind of molding to be used.
- Normally extrusions are used to produce the parts and to give it shape, but with aluminum die casting, the parts are produced faster in terms of speed and with more net shape than usual.
