Abstract

The invention Ceramic Metal Riser Tube stalk is designed to countermeasure the problems caused by the use of conventional riser tubes. The subject matter uses metals and ceramics combination therefore achieving properties of both materials. The invention reduces safety risks of Riser tube replacement, down time, reduces losses caused by casting defects and it is economical to manufacture. Components of the subject matter can be reused for further economic benefits.

Claims

exact text as granted — not AI-modified
1 . Ceramic Metal Riser Tube stalk works in combination with molten metals, its material, design and construction are to reduce chemical reactions between the invention and molten metals therefore giving it long operational life. 
     
     
         2 . High strength materials used in the main body ( 4 ) give resistance to mechanical shock. It provides a strong base for Ceramic Metal riser Tube Stalk construction and supports ceramic or protection sleeves ( 5 ), ( 6 ) and thereof. 
     
     
         3 . The invention remains airtight even after damage to its components ensuring Low Pressure Die Cast product quality is not compromised.
