JEWELLERY CASTING
New Bulk Jewellery Casting Equipment Powers Trend-Driven Production in South Africa
In South Africa’s evolving jewellery industry, the ability to respond quickly and affordably to market trends is more important than ever. From mixed metal styles to oversized gemstone rings, modern jewellery design demands precision, speed, and consistency.
At Precious Metals Tswane (PMT), we’ve made a bold move to support this shift: investing in new bulk jewellery casting equipment that enables larger trees, faster production, and superior quality at competitive prices. This advancement gives jewellers and goldsmiths across South Africa more supplier choices, while elevating the standards of local manufacturing.
Jewellery Casting Technology
How Our Equipment Works
To serve both professionals and students in the jewellery space, it’s essential to understand the power behind modern jewellery casting. PMT’s new machinery uses a combination of medium frequency induction melting, vacuum technology, and inert gases like argon or nitrogen to achieve high-quality results.
Key features include:
-
Vacuum Sealing with Inert Gases
By using argon or nitrogen as inert gases (Learn more), our casting system prevents oxidation, preserving metal purity and achieving clean, dense castings. -
Convex Melting Chamber
The melting chamber has a convex bottom and lid, crucial for maintaining a strong vacuum. Flat surfaces tend to deform, allowing oxygen in, which compromises the casting. A convex shape maintains structural integrity under pressure and ensures a stable casting environment. -
Medium Frequency Induction Melting
This method features a self-mixing effect, which guarantees homogenous alloys. The melting cluster’s titer is consistent throughout, meaning less porosity and fewer structural flaws (See how induction melting works). -
Dynamic Double-Jointed Arm
This feature allows molten metal to flow evenly into the center of the casting cylinder, improving metal fill and surface detail.
This sophisticated technology allows for precision jewellery casting at scale, supporting everyone from boutique designers to academic institutions training the next generation of jewellers.
Trends That Our Jewellery Casting Supports
- Mixed Metals and Custom Alloys
Modern consumers want choices. Our advanced casting setup can handle simultaneous pours of yellow, white, and rose gold, along with silver and palladium silver alloys—ideal for fashion-forward collections and cost-effective designs. - Statement Gemstone Settings
Bolder designs with tanzanite, garnet, and topaz require deep and secure settings. Our jewellery casting process provides the strength and precision needed for these complex pieces. - Speed for Custom Orders
With personalised jewellery and CAD-designed pieces on the rise, jewellers need quick turnarounds. Our large casting trees and high-throughput system allow faster delivery, even in custom runs. - Supporting Local and Ethical Manufacturing
As awareness grows around sustainability and ethical sourcing, local casting services are becoming more desirable. PMT helps reduce the need to outsource internationally, saving time, cost, and emissions.
