Custom Gravity Cast Service for You

Custom gravity cast service is a type of casting process in which a molten metal is poured into a mold using the force of gravity, without any external pressure or vacuum. This process is commonly used to produce complex and high-quality metal parts for a variety of industries, including automotive, aerospace, and medical.
Custom Gravity Cast Service for You
  • High precision: Gravity casting can produce parts with very high dimensional accuracy and tight tolerances, making it suitable for producing complex and intricate parts.
  • Good surface finish: Gravity casting can produce parts with smooth surface finish, reducing the need for post-processing and saving time and cost.
  • Wide range of materials: Gravity casting can be used with a wide range of materials, including aluminum, magnesium, zinc, copper, and bronze, allowing for greater design flexibility.
  • Low cost: Gravity casting is a relatively low-cost casting process, making it an attractive option for small and medium-sized production runs.
  • Low tooling cost: The tooling cost for gravity casting is typically lower than other casting methods, making it an ideal choice for prototypes and low-volume production.
  • Good mechanical properties: Gravity cast parts typically have good mechanical properties and can be used in demanding applications that require high strength and durability.

Mold Design
The first step is to design the mold for the desired part. The mold is usually made of steel or aluminum, and it is designed to accommodate the molten metal and produce the desired shape.
Mold Preparation
Once the mold is designed, it is cleaned and prepared for the casting process. This may involve applying coatings or other materials to prevent the molten metal from sticking to the mold.
Material Preparation
The metal is then melted in a furnace, and any impurities or gases are removed through degassing or other processes.
Pouring the Metal
Once the metal is ready, it is poured into the mold using the force of gravity. The molten metal fills the mold, and the excess is poured off.
Cooling the Mold
The mold is then cooled to allow the metal to solidify and take on the shape of the mold. The cooling time may vary depending on the size and complexity of the part.
Removing the Castings
Once the metal has solidified, the mold is opened, and the casting is removed. Any excess material or rough edges are removed through trimming or other finishing processes.
Heat Treating
Depending on the requirements of the part, heat treatment may be necessary to improve its mechanical properties. This involves heating the part to a specific temperature and then cooling it in a controlled manner.
Finally, the casting is finished according to the desired specifications, which may include polishing, coating, or painting the surface. The finished part is then ready for use.

Importance of Choosing the Right Gravity Cast Material

Choosing the right gravity cast material is crucial for achieving the desired characteristics and performance of the final product. Different materials have varying properties such as strength, durability, corrosion resistance, and thermal conductivity. The right material selection can also impact the cost and production time of the casting process. Proper selection of materials can help to optimize the overall design, functionality, and longevity of the final product. Ultimately, selecting the right material for gravity casting can ensure the highest quality and reliability of the end product.
