Product Description
Ceramic Riser Tube for Aluminum Alloy Die Casting
High temperature resistance · Corrosion resistance · Long life · Customizable
Ceramic riser tube is the core component of the low-pressure casting process, mainly used to smoothly transport molten metal from the holding furnace to the mold cavity. We mainly supply aluminum titanate (Al2TiO5) riser tubes and silicon nitride (Si3N4) riser tubes, which are specially designed for transporting aluminum alloy molten liquid, ensuring smooth filling and preventing oxide inclusions, thereby significantly improving casting yield.
Silicon nitride (Si3N4) riser tubes are a high-performance ceramic material riser tube designed for aluminum alloy casting environments. With its ultra-high temperature resistance, excellent thermal shock resistance, and extremely strong corrosion resistance, silicon nitride riser tubes perform well in high-end precision casting fields (such as automotive, aerospace components), which can significantly improve casting quality and reduce maintenance costs.
Key Function
Suitable processes: low-pressure casting, differential pressure casting
Advanced Ceramic Lifting Pipe Si3N4 Stalk Tube for Aluminum Alloy Castings
Working principle:
It is usually a vertically placed ceramic tube, one end of which is connected to the molten metal in the insulation furnace, and the other end leads to the mold pouring system. Under the pressure of compressed gas (usually inert gas), the molten metal rises along the riser and fills the mold through the gate. After the filling is completed, the pressure is released and the unsolidified molten metal flows back to the insulation furnace.
Application Areas
Industry in-depth cultivation: more than 10 years of experience in the research and development of aluminum alloy casting materials, serving customers around the world.
Strict quality control: ISO 9001 certified, each batch is tested for air tightness, pressure resistance and microstructure.
Customized service: provide personalized design solutions based on customer mold structure, alloy composition and production rhythm.
Support sample delivery · technical consultation · after-sales tracking
Q: What Parameters should I provide to you for a proper quotation?
A: Application, pore size, dimension, color, quantity, packing requirements, trade terms.
Q: How can you control your quality?
A: We have a complete QC system for the chemical composition and physical properties of each production process. After production, all the goods will be tested, and we have the quality certificates with ISO9001.

We mainly supply aluminum titanate (Al2TiO5) riser tubes and silicon nitride (Si3N4) riser tubes, which are specially designed for transporting aluminum alloy molten liquid, ensuring smooth filling and preventing oxide inclusions, thereby significantly improving casting yield.
Resistant to thermal shock, resistance to sudden cooling and heating
Resistant to erosion, resistant to aluminum liquid corrosion, long life
High mechanical strength, high toughness, impact resistance, and good wear resistance
Silicon nitride (Si3N4) riser tubes are a high-performance ceramic material riser tube designed for aluminum alloy casting environments. With its ultra-high temperature resistance, excellent thermal shock resistance, and extremely strong corrosion resistance, silicon nitride riser tubes perform well in high-end precision casting fields (such as automotive, aerospace components), which can significantly improve casting quality and reduce maintenance costs.
Key Function
Metal liquid transportation: ensure directional and smooth flow of molten metal.
Flow control and oxidation prevention: reduce turbulence and gas entrapment, and some designs are sealed or coated to isolate air.
Temperature maintenance: The material needs to be resistant to high temperatures to avoid clogging caused by the solidification of the molten metal.
Suitable processes: low-pressure casting, differential pressure casting

Application Areas
Aluminum alloy wheel: a typical low-pressure casting product, the riser tube needs high corrosion resistance.
Automotive parts: such as engine cylinder block, housing, etc.
Complex thin-walled parts: precision castings that require smooth filling.
