Understanding the Gravity Die Casting Process
Gravity die casting is a commonly used method of casting whereby a hallow mold is filled with molten metal under the forces of gravity. Unlike pressure die casting, where in external forces are applied to the molten metal to push it inside the mold, in gravity die casting, the molten metal is allowed to flow into the mold as a result of its own weight. This process is popular in automotive and aerospace industries because it yields parts of good mechanical properties of high dimensional and geometrical precision.

What is Gravity Die Casting?
In the gravity die casting process, molten metal is introduced into a reusable metallic mold (referred to as die as well) via gravitational force. The mold is manufactured of steel or cast iron and is made for multiple usages making the cost of the manufacturing process for medium to high quantity casting runs very economically efficient. Molds are manufactured in a way that they are quite complicated geometrically and built with fine details opening doors for mass production of accurate parts.
Benefits of Gravity Die Casting
Exceptional Quality of Castings
High quality gravity die casting services involve producing high quality castings with very high dimensional accuracy and surface quality. This means that it is appropriate for parts which have close fittings and need a fine finish.
Economical for Medium to Large Scale Production
The fabrication of a recoverable metal mold has a relatively high initial cost, however as gravity die casting can be carried out repeatedly, this makes it‘s cost beneficial for medium to large runs. Also reduces the amount of materials that are wasted when compared to other casting techniques.
Improved Mechanical Properties
Parts achieved by gravity die casting are usually of better mechanical properties than those attained through sand casting. The solidification process is enhanced through cooling, which increases the cast components mechanical strength and toughness.
Different Types of Materials
Gravity die casting can use various metals such as aluminum, or zinc and copper alloyed with magnesium. Each one presents a different property magnifying the opportunity of the manufacturer to pick the right one for the desired use.
Key Steps in the Gravity Die Casting Process
Preparation of the Mold
To achieve correct and continued flow of metals within the mold, it is essential to preheat the mold before casting. The required temperature depends on the alloy type being cast. Also, usually a core release agent is coated to the mold so as to reduce metal bonding and enhance the quality of the final product.
Pouring the Molten Metal
When the mold is ready, molten metal, aluminum alloys, zinc alloys, or copper alloys usually contained in a ladle is poured into the mold cavity. The filling of the mold with the metal occurs purely through the activity of highly accelerated gravity which effectively reaches every corner of the mold’s geometry.
Solidification and Cooling
Casts are formed whenever the mold has been filled by the molten metal and the metal cools within the internal section of the mold. The new cast part can be susceptible to changes depending on the cooling speed, so uniform cooling can be done to eradicate chances of deformities like shrinkage or even pores. After sufficient cooling processes have occurred until the metal is fully solidified, the mold is taken apart and the casting removed.
Finishing and Trimming
When the cast is taken from the mold any extra material such as runners and risers will be cut off. Sometimes, it is also necessary to use some finishing operation, for example, machining, polishing, heat treatment, etc. for the surface or mechanical properties of the final part.
Common Applications of Gravity Die Casting
• Automotive Industry
Gravity die casting technology is widely applied for manufacturing engine components, transmission cases, cylinder heads and other structural parts in the automobile industry. Because of this feature, it also allows increasing the general performance and reducing the fuel consumption of the automobile.
• Aerospace Industry
Components used in the aerospace industry are often fabricated using gravity die casting due to the strength to weight ratio required of aircraft engine parts, landing gear components and supporting structures.
• Consumer Goods and Electronics
A large number of appliances and electronic devices contain gravity die adjustable parts: light and strong aluminum covers and brackets.
