Precious Metal Casting
Schultheiss sealed-chamber casting in 9K to 22K gold and sterling silver, with Fischer XRF karat verification on every piece.
State-of-the-art casting technology
We have partnered with industry leader Schultheiss to deliver casting quality for discerning manufacturers. Our equipment represents the pinnacle of metallurgical engineering, producing exceptionally clean castings that measurably reduce downstream finishing time and labour cost.
The Schultheiss systems feature
- Sealed melting chamber technology that eliminates oxidation during the critical melting phase
- Advanced homogenisation ensuring consistent karatage throughout every piece
- Proprietary ash reduction technology for exceptionally clean casting results
- Computer-controlled process management for reliable, repeatable quality
Rigorous quality verification
Every casting undergoes
- Fischer XRF analysis, giving precise karatage verification across all pieces
- Review by a dedicated quality control department with strict tolerance standards
- A multi-point inspection protocol for surface finish and structural integrity
- Documented quality assurance for complete production transparency
Comprehensive material expertise
- Gold casting in all standard karatages: 9K, 10K, 14K, 18K, 22K
- Multi-colour gold, including yellow, white and rose
- Sterling silver casting, with anti-tarnish formulations available
- Speciality alloy development for custom applications
Bring your own metal or use ours. Both are entirely standard here, and the choice changes nothing about the process or the result.
Silver casting and production
The same factory, the same equipment and the same quality control handle sterling silver production alongside gold. Silver behaves differently in the melt: it is more prone to oxidation and firescale, so it is cast on the same sealed-chamber Schultheiss systems that make our gold work clean. That keeps silver castings bright and reduces the finishing needed afterwards.
What we offer in silver
- Sterling silver (925) casting for production runs and one-off pieces
- Anti-tarnish formulations available where the piece will sit in retail stock
- The same Fischer XRF verification and QC protocol applied to gold
- Silver prototyping ahead of a gold production run, to prove a design at lower material cost
Specialisation in complex forms
We cast every jewellery category, but our equipment delivers a particular advantage on the hard ones.
- Precision bangle casting with superior surface finish and dimensional accuracy
- Complex chain components with intricate detail and consistent quality
- Hollow form jewellery with exceptional wall thickness control
- Stone-in-place casting for selected gemstone types
