OTEC Machines
Engineered in Germany, OTEC machines deliver flawless, mirror-like finishes with unmatched speed and consistency. They automate tedious bench labour and protect delicate jewellery geometries across every batch.
OTEC MAG-30
The OTEC MAG-30 is a stand-alone industrial magnetic finishing system designed for high-throughput jewellery workshops requiring repeatable post-cast refinement, surface burnishing, and general clean-up within a single platform.
Built around a heavy-duty drive system with precision frequency control and a touchscreen interface, the MAG-30 allows full programming of RPM, cycle time, and real-time process monitoring during operation. Strong base magnetics combined with high-grade inverter technology ensure stable, consistent pin action across the entire working bowl, delivering reliable finishing results batch after batch.
Supplied with 300 g of European-made magnetic pins, the system is engineered for aggressive yet controlled surface refinement, outperforming conventional magnetic pin units in both finish consistency and cycle efficiency.

Raw Casting Brightening
(0.50 × 5.00 mm pins)
Brightens raw casted pieces that come after vapour honing, producing a uniform, high-lustre surface suitable and most desirable for bench jewellers to begin casting clean-up.
Surface Burnishing
After casting clean-up (0.30 × 5.00 mm pins)
Refines and burnishes the casted surfaces following initial casting cleaning behind the behind (typically #600 grit equivalent), improving overall smoothness and preparing all casted pieces for downstream OTEC post-processing systems such as CF disc finishing and/or EF electro-polishing.
Casting Tree & Button Clean-up
(1.00 × 7.00 mm pins)
Provides controlled mechanical cleaning and polishing of larger and heavier casting remnants such as left over casting trees and buttons, reducing manual clean-up time and improving workflow efficiency for casting houses.

Why Choose the OTEC MAG-30
Consistent Finishing Results
Precision-controlled magnetic pin action delivers even, repeatable surface refinement across every batch, helping improve finish quality and process consistency.
Faster, More Efficient Processing
Automated cycle control reduces manual bench work and speeds up post-cast cleaning, burnishing and brightening for higher-volume production environments.
Built for Jewellery Production
Designed for cast jewellery, the MAG-30 can handle everything from delicate surface refinement to heavier casting-tree and button clean-up within one versatile system.
Advanced Magnetic Finishing for Jewellery
The MAG 30 is a state-of-the-art magnetic polishing system designed specifically for gold and silver jewellery.
It delivers a refined, consistent surface finish after casting, helping reduce manual clean-up while preparing pieces for the next stage of production.
