High Pressure Die Casting: Process and Applications
The process High pressure die casting encompasses a wide variety of manufacturing processes that enable the rapid production of intricate precisely dimensionsed metal parts that are surface finished. This phenomenon is achieved through the injection of molten metal into a steel die at very high pressures, thereby allowing relatively intricate and accurately dimensioned parts to be formed. Because of the speed, repeatability and precision of processes like High pressure die casting, it is very popular in automotive, aerospace, telecommunication and other industries.

The Steps Involved in High Pressure Die Casting Process
The die preparation starts when the steel die that consists of requiring two halves known as cavity and core is prepared. The die is smeared and heated up to prevent the molten metal from solidifying too quickly and facilitate the easy removal of the cast part. Lubricating agents also assist in prolonging the life of the mold since they help to minimize the wear and tear that results from excessive casting.
Injection of Molten Metal Into the Mold
As soon as the preparation of the pattern is completed, liquefied metal (normally Aluminum, magnesium and Zinc) under great pressure between 1500 to 25000; usually injected into the mold cavity. The molten metal is pushed by the high pressure into every corner and side of the mold right up to the intricate designs where cooling occurs to every detail consistently.
Solidification and Cooling
The metal in the cavity undergoes cooling and solidification in a very short period of time. The cooling process quite rapid enables the metal to structure into a fine-grained microstructure further making the part have enhanced mechanical properties such as strength and durability.
Injection of Molten Metal
When cooling is completed, the mold is demold and the casting is removed from the sprue. The part is cut free from unwanted flash that remains on it after the molding which contains the raw end result. Further operations such as machining or surface texturing may be done for end products having certain specifications.
Scrap is Recovered and Recycled
One of the disbenefits of HPDC is the waste that is generated during this process where scrap metal such as those from trimmed flash are useful as they can be recycled and therefore reduce the wastage of material and help in the eco-friendliness of the process.
Materials Which Can Be Royally Heat Treated In High Pressure Die Casting
• Aluminum: Noted for its especially low weight especially in the industry, it is arguably the most used material in HPDC engineering. It also exhibits great anti-corrosive properties making it useful in industries such as the automobile and aerospace where it is necessary to reduce weight as much as possible.
• Magnesium: Magnesium is even more lighter than aluminum hence it is used in places that need a very light weight such as in mobile phone parts or car parts.
• Zinc: Zinc can easily fill every corner of a cast due to its good fluidity. This material is used frequently to create parts of electronic devices, vehicles, and in other precision machines.
Uses of High Pressure Die Casting
Because HPDC is able to create parts with high accuracy and smooth finishes, it is employed in a lot of industries. It has numerous notable applications which include:
Automotive Industry
The automobile Manufacturing is rated as the greatest consumer of hpdc parts. The automotive die cast industries make use of diecasted aluminum and magnesium components which are beneficial in weight reduction of the automobiles without compromising on their strength and durability.
Some of the common automotive screws applications include:
o Engine Blocks: Casing technology Modified Pressure Die Casting ( HPDC) is applied in the manufacture of engine blocks and housings as these require strength, heat endurance and ordinate accuracy.
o Transmission Cases: The weight of the material, which is a die-casted aluminum, magnesium, is comfortable in manufacture of transmission cases and gear boxes since they are durable but light.
o Wheels and Chassis Components: Extremely high strength, low weight parts assist in reducing the overall weight of the vehicle in turn improving efficiency and performance.
