Best for: Customers who need maximum time savings, maximum reduced gold loss behind the bench & a flawless polish all over including inside setting areas for the setters to pop the stones in immediately.
For workshops requiring the highest level of finishing and move straight to setting without pre-polishing stone areas, our Ultimate Post-Processing service combines manual refinement, OTEC disc finishing and OTEC electro-polishing.
This process is designed to take surface preparation further, including selected areas within stone-setting regions where the design allows.
For suitable designs and applications, this can reduce pre-setting bench labour by up to 98%.
Acid bathing, vapour honing, flow gate removal, sprue flush cut & magnetic pin finishing.
Sprues and flow gate contact points are filed and profiled perfectly.
Visible printing lines are removed from accessible external surfaces and internal setting areas.
Magnetic pin finishing to burnish and refine the surface and reach difficult areas.
Two stages of ceramic and hybrid wet-grinding processes further refine the casting surface.
One stage of flawless electro polishing throughout the entirety of the casting.
