Kalman Hafner GmbH

What Kalman Hafner GmbH does

Kalman Hafner GmbH is a family-owned B2B contract jewellery foundry and finishing service provider based in Pforzheim, Germany, founded in 1967 by Kalman Hafner after his training at the Pforzheim Goldsmith School. The company operates from a single integrated facility in the centre of Pforzheim — historically known as Germany's 'Golden City' for jewellery production — and serves jewellery manufacturers, independent designers, and goldsmiths throughout Europe. Production is now led by second-generation CEO Robin Hafner, with a team of approximately 9 employees and a broader group of authorised signatories drawn from the Hafner family and long-tenured staff.

The firm's core offering is an end-to-end single-source production platform that covers CAD construction, 3D printing and rapid prototyping, rubber and silicone moulding, vacuum casting in gold, silver, platinum, brass, bronze, and copper alloys, goldsmith works, and electroplating (including gold, rhodium, palladium, ruthenium, silver, brass, and copper finishes), with laser work provided through competent partner companies. Technology assets include Solidscape 3Z Pro and Projet CPX 2500 wax printers, an Envision Tec P4 Mini XL resin prototyping system, modern coded wax injection machines, and a full vacuum casting and electroplating plant. The company additionally offers Fairtrade (FLO-ID 47278) and Fairmined (DE20017) certified precious-metal options, giving customers an ethically sourced supply chain pathway for gold and silver alloys.

Revenue is generated through quote-based project pricing for each casting job, with small-quantity surcharges applied to orders of fewer than four pieces, recurring storage fees of approximately €10 per customer mould, and precious-metal account management with floating-price adjustment provisions. Go-to-market is sales-led enterprise field engagement with direct phone and email contact, supported by a professional website and a MailChimp-managed consent-based newsletter. Distribution is via DHL, UPS, and the LRM/MBE franchising partner for cross-border European delivery. The company maintains an archive of over 350,000 stored customer models and rubber moulds, which functions as both proof of historical capability and a structural switching-cost moat for the existing customer base. No external funding, parent company, or public listing is present.
