Product Details

Sealing paste is a sealing material used in the casting process. It is mainly used to seal the gaps in the sand mold to prevent the leakage of molten metal. , to ensure the quality and accuracy of castings.

Sealing paste usually has thermal insulation properties; binders are used to bond refractory powder and additives together to form a sealing layer with a certain strength and adhesion; additives are used to improve the performance of the sealing paste, such as flow properties, coating properties, drying speed, etc.


The pouring riser is a channel used to pour molten metal and remove gas during the casting process.

The gate is the entrance for molten metal to enter the mold cavity, usually located on the upper or side of the casting. The shape and size of the gate depends on the shape and size of the casting, as well as the design of the gating system.

The riser is a channel used to remove gas from the mold cavity, usually located at the top or upper part of the casting. The shape and size of the riser depends on the shape and size of the casting, as well as the emission of gas in the mold cavity.


Ceramic filter for casting is a kind of filter material used in the casting process. It is made of ceramic material and has the characteristics of high temperature resistance, corrosion resistance and high strength.

Its main function is to filter out impurities and oxides in the molten metal during the pouring process and improve the quality and accuracy of castings.


Nodulizing agent is an additive used in the casting process. It is mainly used to make the graphite in cast iron spherical, thereby improving the mechanical properties and wear resistance of cast iron.

It is composed of magnesium, rare earth and other elements. According to different cast iron materials and requirements, spheroidizing agents with different compositions and ratios can be selected.


Inoculant is an additive used in the casting process. It is mainly used to promote the formation of graphite and the refinement of grains in cast iron, thereby improving the mechanical properties and wear resistance of cast iron.

It is composed of silicon, calcium and other elements. According to different cast iron materials and requirements, inoculants with different compositions and ratios can be selected.


Slag aggregating agent is an additive used in the casting process. It is mainly used to gather and remove oxides and impurities in molten metal, thereby improving the quality and accuracy of castings.

Made of bentonite, sodium carbonate and other materials, it has good adsorption and disintegration properties.
