Global Collaboration, Local Precision:

Partnering with OTEC for Advanced Jewellery Finishing

We travelled to Germany and worked closely with OTEC's technical experts to develop, refine and validate advanced post-processing methods specifically for the jewellery industry, combining high-quality surface finishes with improved efficiency, consistency and repeatability.

Through our validated batch-processing workflows, we can provide tailored solutions to suit the specific requirements various clients across the jewellery industry. From high-volume jewellery manufacturers and casting workshops seeking greater speed, flexibility and efficiency, to smaller workshops requiring specialised, small-scale processing, our solutions are designed to reduce manual bench labour, improve consistency and help minimise precious metal loss.
