Innovacera supply ceramic piston and plungers with various materials, such as alumina ceramics, zirconia ceramics, silicon nitride and silicon carbide.

To produce the epoxy resin components, the casting machine request wear resistance, corrosion resistance and chemical inertness material as piston and plunger. Innovacera recommend you can chooose the silicon nitride and silicon carbide material as ceramic material to make piston and plungers.

Silicon nitride (Si3N4 ceramic) is black or dark grey colors, it is a non-oxide structural ceramic material and can be polished to give a smooth and strikingly reflective surface appearance. Its main properties is its high thermal shock and chemical inertness, main applications include vacuum casting machine, 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 degree Celsius.

Silicon nitride and silicon carbide ceramic piston and plungers Innovacera produced:
