Produce Umbrella Base - Cast Iron Base

Umbrella base is a kind of cast iron base used for outdoor flags and umbrellas. Dandong Foundry in China is producing this product for customers in USA and Mexico. Its material is grey iron ASTM A48 Class 30. Weight range from 50 kg to 100 kg.

We produced these bases by green sand casting process and resin sand casting process. The surface quality is a main difficulty to produce them. Although welding is permitted, but large casting defects will cause more problems.

We used resin pattern to produce them, the steel sand boxes need to be made customized. These bases are large and thin, both top and bottom need good surface quality, so normal sand boxes can not produce this product.
