Product Description

Ceramic Riser Tube—Designed For Aluminum Alloy Die Casting

High temperature resistance · Corrosion resistance · Long life · Customizable

Ceramic riser tube is the core component of 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 aluminum alloy molten liquid transportation, ensuring smooth filling and no oxide inclusions, significantly improving the casting yield.

Product Description

Aluminum titanate (Al₂TiO₅) Riser Tube

Aluminum titanate (Al₂TiO₅) riser tube is specially designed for low-pressure casting of aluminum alloy. It has excellent thermal shock resistance and aluminum liquid corrosion resistance, and can work stably for a long time at a high temperature of 1000℃.

Its unique low thermal expansion characteristics effectively prevent cracking. It also has high strength and good economy. It is a cost-effective choice for the production of conventional castings such as aluminum alloy wheels and housings, which can significantly improve production efficiency and casting yield.

Product Advantages

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, good wear resistance

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 solidification of the molten metal.

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

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.
