Piezoelectric ceramic elements manufacturing process

The full production process is as follows: Prepare Raw Materials — Mixing — Calcining — Vibrating Abrasive — Spray Granulation — Forming —Debinding — Sintering — Grinding Inner & Outer Circles — Cutting — Grinding Double Sides — Chamfering — Cleaning & Drying — Sorting — Printing Silver & Burning Silver — Polarization — Ageing — Testing — Packaging. Therefore, the customization cycle generally will take 2 to 3 weeks.

① Debinding: remove the binder added during granulation from the blanks;
② Sintering: the blanks are sintered into ceramics in a high-temperature tunnel furnace;
③ Electroding: Make conductive electrodes on the surface of the ceramic elements. (That is “printing silver and burning silver”);
④ Polarization: It makes the electric domains inside the ceramic oriented and arranged. Thus, the ceramic has piezoelectric properties.
