What are foundry sleeves?
Foundry sleeves are also known as feeders. It can store in molten steel to increase the yield of the casting process. It is not part of the final casting material.
It has been replace the molten metal when the metal shrinks, to avoid shrinkage holes on the castings.
SEFU Foundry Sleeves Application
Sefu Foundry sleeves apply to steel castings to discharge the air in the mold and the impurities in the molten metal during casting. SEFU foundry feeder has been strictly tested and inspected.
SEFU Foundry Sleeves Functions
It has the double functions of heat preservation and heat generation, which has the function of feeding castings and preventing shrinkage cavities and shrinkage porosity. It can improve the process of yield and reduce the repair areas of castings.

FAQs About the Foundry Sleeves
SEFU integrates the production of exothermic riser sleeves, ceramic pouring cups, ceramic filters, and various casting materials. We are dedicated to researching foundry solutions that improve the quality and yield of castings.
We look forward to you exploring more foundry solutions with us.
The solidification time of the metal liquid in the foundry sleeves is long, the feeding effect is good, the heat preservation performance is good, the refractoriness is high, the use is convenient, there is no environmental pollution, and it is easy to promote.
The insulating sleeves made of low thermal conductivity material is called thermal insulation riser.
