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.

Frequently Asked Questions
Looking for a wear-resistant ceramic pistons supplier? Why choose silicon nitride and silicon carbide over traditional metals?
Metal pistons in high-pressure pumps and vacuum casting units fail rapidly due to abrasive wear, galling, and chemical corrosion. INNOVACERA supplies silicon nitride (Si₃N₄) and silicon carbide (SiC) pistons and plungers that offer exceptional surface hardness, thermal shock resistance up to 1000°C, and total chemical inertness. Their mirror-polished finish significantly reduces seal friction, eliminating fluid leakage and extending maintenance intervals.
Need custom ceramic plungers and sleeves for epoxy dosing? How do precision-matched clearances prevent fluid backflow?
Dispensing viscous epoxy resins and abrasive chemicals demands micron-level tolerances between the piston and sleeve. INNOVACERA manufactures custom ceramic piston-sleeve assemblies with precision-ground diametrical clearances down to 2–5 microns. Combined with non-stick surface qualities and thermal stability, our custom components prevent material jamming, dripping, and costly production downtime.
