For 26 years ZPI continued to use the "ZIRCAR PROCESS" to make Zirconia fiber materials. During this time ZPI's business grew and other materials and processes became important. In 2000, three ZPI factories were making three distinctly different product lines and were run by six of Bernie H. Hamling's children.

Zircar Zirconia, Inc. employs the original "ZIRCAR PROCESS" method of manufacturing of Yttria stabilized Zirconia fibers, cloths and felts as the basis of its business.
