What is Shell Mold Casting?
Shell Mold Casting is a specialized casting process known for its ability to produce high – precision parts. It involves creating a thin, hardened shell around a pattern and also put the Shell Core inside the Shell Mold. This shell acts as the mold for pouring molten metal. The process offers excellent dimensional accuracy and surface finish, making it suitable for a wide range of industries.
Leesh Resin Sand Casting Service
Shell Mold Casting is once casting method of Leesh’s Resin Sand Casting Service which is suitable for high precison sand casting requirments.
But the Shell Mold Casting always has weight limit from few dozens grams to dozens kgs.
Hot Shell Molding Castings
Hot shell molding is a key aspect of shell mold casting. In this process, the pre – coated resin sand is heated to a specific temperature, usually around 250 – 300°C. The heated sand is then applied to a heated pattern. As the sand contacts the pattern, the resin binder melts and bonds the sand particles together, forming a hard shell. This shell is strong enough to hold the molten metal during pouring, resulting in Hot Shell Molding Castings with precise dimensions.
Core Casting Process
The core casting process in shell mold casting is used to create internal cavities in the castings. Cores are made from pre – coated resin sand and placed inside the shell mold before pouring the molten metal. These cores are designed to withstand the heat of the molten metal and maintain their shape, ensuring the accurate formation of internal features in the final casting.
In conclusion, shell mold casting, along with Leesh’s Resin Sand Casting Service, offers a reliable and efficient solution for producing high – quality castings. Whether it’s hot shell molding or core casting, the process can meet the diverse needs of various industries.
