Processing technology for molding complex structures in either ceramic or pure metals, based on the special Metal Injection Molding process, created completely new design possibilities and has successively been introduced by Ortofon suppliers in either ceramic, stainless steel or pure iron parts.
In 2004 Ortofon started using a wood-powder resin material for new SPU-G housings as well as for the Rondo models.
Contrary to other types of phono catridges, the moving coil principle is not suited for mass production. Each of the four coils contains between 11 and 24 turns of wire, depending on model, and has to be wound by hand under a microscope.
The high degree of craftsmanship involved is one of the "secrets" behind Ortofon's reputation.
