Ceramic Pistons and Plungers

Innovacera supplies ceramic pistons and plungers with various materials, such as alumina, zirconia, silicon nitride, silicon carbide, and so on.

The variety of silicon nitride and silicon carbide pistons and plungers have evolved in response to growing interest in their application in manufacturing epoxy resin components, mechanical equipment, high-pressure pumps, and other engineering applications.


To produce the epoxy resin components, the casting machine requests wear resistance, corrosion resistance, and chemical inertness material such as piston and plunger. Innovacera recommends you choose silicon nitride and silicon carbide material as ceramic material to make pistons and plungers.

Silicon nitride (Si3N4 ceramic) is black or dark grey color, it is a non-oxide structural ceramic material and can be polished to give a smooth and strikingly reflective surface appearance. Its main properties are its high thermal shock and chemical inertness, its main applications include vacuum casting machines, shot dosing equipment, and so on.

Silicon nitride and silicon carbide ceramic piston and plungers features:

High wear resistance
Excellent surface smoothness
High Thermal Shock resistance
No Chemical decomposition in heating to over 1000 degrees Celsius.
