Metallizing

Metallizing Protects & Bonds Ceramic Components


Metallizing is the moly-manganese coating applied to a seal’s ceramic component. It enables the seal to bond hermetically to the metal portion of the seal.

One of the keys to Specialty Seal Group’s success is the strength and permanence of our metallizing interface. More than 50 years of ongoing research & development have yielded formulations and processes that have given us the distinction of having the industry’s highest-quality metallizing.

Specialty Seal Group monitors metallizing strength every day through in-process control by Push-Test analysis (see Statistical Process Control graph at right). Quality control can provide lot integrity and statistical evidence to assure product reliability.
