Processing of Die Castings used for Airplane Parts
Processing of Die Castings used for Airplane Parts. Die Castings used for airplane parts are increasingly demanded for the aircraft industry. This type of constructions need light weight for mobility. Moreover, it requires durability and resistances to several stresses while flying. Among metals, aluminum is processed to serve as frames or skeleton of the aircraft.
In the process of die casting, molten metal is quickly forced into a mold cavity, which is formed by two opposing dies. Very high pressures are maintained until the metal solidifies. As for aircrafts, the strength of aluminum is significantly increased by high pressure casting. It creates yield of 69%. Aluminum die castings used for airplane parts are strong against torsion and expansion stresses. These are important considerations since a flying aircraft is subjected to several forces.
In this machining process, there is always an associated imperfection called porosity. This is the amount of gas that combines with the solidifying metal, as it cools in the mold. Porosity is characterized by the size and number of air bubbles inside the finished product. There are three levels of porosity. The second and third levels are unacceptable when it comes to machining airplane parts. This is to guarantee safety of the passengers. Advanced technology in treating aluminum is applied to minimize the porosity of the frames.
Die castings used for airplane parts are usually made of different aluminum grades. For example, Al 7075 is commonly used for making frames because of its toughness. Al 5052 can be die casted into billets, planes, coils, tubes and bars.

Metal Die Castings Used for Car Parts
Metal Die Castings Used for Car Parts. In the modern automotive industry, individual cart parts are required to be strong, durable and with a good finish. Hence, die castings used for car parts and accessories have been the standard for the industry. High pressure die casting is a metal-working process that can produce highly detailed parts. These are perfect both for internal parts for motors and transmission. Die castings have high yield strengths and tensile resistance too.
Basically, die casting is performed for automotive parts through a pair of dies. Molten metal is injected to the cavity between the dies. Then, a pressure between 10-175 MegaPascals is sustained until the metal solidifies. The product piece is uniform inside and out, with minimal porosity and external scrap. It has a yield of about 70%. Because of the speedy operation, the method is recommended for large scale productions.
Die castings used for car parts include sprockets, gears, fixtures and frames. Sprockets’ specifications are obtained almost perfectly after casting, resulting in smooth contact with the chain. There is no need for grinding or sanding. The method can also be used for small gears, but they are not suitable for high loads or rotating speeds.
Most frames and fixtures for automotive are die castings used for car parts. They are commonly shaped from Aluminum, a metal with high tensional strength. Because of aluminum’s high melting point, the recommended the process is cold chamber die casting. After casting, there are only few post-machining tasks to do. These involve cutting out of holes for assembly and screws.

Tips on Maintaining Tooling Made for Die Casting
Tips on Maintaining Tooling Made for Die Casting. Die casting assemblies are recommended for large-scale metal working. Because pressure is applied on molten metals, which cool pretty quickly, may products can be processed in a short period of time. A company must be sure that its tooling made for die casting is in optimal conditions. This will help avoid malfunction of the assembly or factory defects like excessive porosity.
The die casting process involves two die molds: the cover die and the ejector die halves. Molten metal is injected through an opening in the cover die. Once the product has solidified, it will be released through the ejector die half. Always check if the ejector pins on the ejector die half are working. They are used to push the product out of the mold.
Fluid lines are also important tooling made for die casting. Waterlines supply the system with water as coolant and lubricant. This will increase the number of cycles per hour. The vents should also be clear, so that gasses can easily escape during casting. If gasses are trapped during the rapid casting process, there are risks of forming large air bubbles. This will cause porosity and tensile weakness on the final product.
Finally, be sure that you are equipped with trim die tooling made for die casting. This is particularly needed for aluminum processing assemblies. The trim die removes excess aluminum, which are imperfections from the casting process. It helps in producing a finer surface finish. The scrap aluminum can be recycled for future castings. Hence, it will save production costs.

Minimizing Porosity in Die Casting Parts
Minimizing Porosity in Die Casting Parts. Die casting is popular method for machining metal parts for vehicles and electronics. When this method is applied, tough and well-detailed products are produced. However, due to large capital costs of the dies, die castings are preferred only for large scale operations. One important issue in this industry is the tracking of porosity in die casting parts.
In order to understand the concept of porosity in metal working, one must first understand the basics of die casting. Hot or molten metal is forcefully injected into a cavity, at pressures from 10 to 175 mPa. The cavity is then applied with that pressure until the metal freezes or solidifies. The mold cavity is made by two contacting parts: the cover half and the ejection half.
The pressure of injecting the molten metal results in high processing speed. It also induces uniformity, inside and out, of the finished product. However, air in the injection tube mixes with the molten metal during this speedy process. The trapped air bubbles in the product are called porosity in die casting parts. This is often considered a factory defect. If the bubbles are large or interconnected, they can cause loss of tensile strength in the final product.
There are several factors that affect porosity in die casting parts. The manufacturer must be sure that the molten metal is free from impurities and that the molds are clean. The working temperature of the furnace must also match with the metal being processes. Other factors include shot speed, lubrication and amount of pressure.

Cold and Hot Chamber Casting for Motor Vehicle Die Cast Parts
Cold and Hot Chamber Casting for Motor Vehicle Die Cast Parts. Die Casting is an important process in the metal working industry. Do you that most of the parts of your car are motor vehicle die cast parts? Depending on the type of metal used for that automotive part, either cold chamber or hot chamber is casting to machine them. The products include sprockets, rods and gears. Basically, die casting is performed by injecting molten metal into a cavity. The cavity is the shape formed by two dies. Then, this is applied with pressures up to 175 MegaPascals until the metal solidifies. The effects are high yield strength and resistivity to multi-directional fatigue.
Naturally, customers want their automotive parts to be cheap, durable and with a high quality finish. These specifications are easily achieved through automated high pressure die casting. Most of the detailed aluminum parts are motor vehicle die cast parts. Traditionally, sand casting is used to shape car parts. However, sand casting is limited to one piece per mold. Usually, the sand mold is destroyed after one product solidifies. Hence, there are higher production times and costs.
Cold and hot chamber casting for automotive industry solve these problems. It resulted in higher production times and lower post-machining. Pressure die casting results into high yield and smooth finish, which requires little sanding or grinding. Cold processes work on high temperature melting metals, like aluminum and zinc. Hot chamber processes involve weaker metals that can be shaped into gears or one-piece gear trains. Motor vehicle die cast parts have high tensile strengths and are perfect for motors and transmission.
