What are foundry sleeves?

Foundry sleeves are also known as feeders. It can store in molten metal 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 are applicable to cast iron and 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.

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.

What is the advantage of foundry sleeves?

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.

What are insulating sleeves?

The insulating sleeves made of low thermal conductivity material is called thermal insulation riser.
