Ceramic Injection Molding of Zirconia Keyboard Keys
-
Mixing: Zirconia powder is mixed with a thermoplastic binder to form a granulated feedstock.
-
Molding: The feedstock is heated and injected under high pressure into a key-shaped mold, creating a “green part.”
-
Debinding: The green part is treated (often with solvent and heat) to remove the binder, leaving a fragile “brown part.”
-
Sintering: The brown part is fired at high temperature (≈1400-1550°C). It shrinks significantly and densifies into a hard, strong, final zirconia key.
Result: A precise, dense, and extremely durable ceramic key with high wear resistance and a unique, premium feel.
