"INNOVATION THAT SHAPES ELEGANCE"

Delmer Group is a global supplier of advanced goldsmith machinery, jewellery manufacturing equipment, and precious metal processing solutions for jewellery manufacturers, bullion producers, precious metal refineries, mints, laboratories, and industrial processors worldwide.

With decades of engineering expertise, we provide reliable machinery for every stage of jewellery production—from melting and casting to refining, polishing, electroforming, and quality testing. Whether you are setting up a new jewellery manufacturing facility or upgrading an existing production line, our comprehensive range of machinery helps improve productivity, precision, energy efficiency, and product quality.

Our solutions are designed for processing gold, silver, platinum, palladium, and other precious metals while meeting the demanding requirements of modern jewellery manufacturing.

Complete Jewellery Manufacturing Process

Every jewellery product passes through multiple manufacturing stages, each requiring specialized machinery for maximum efficiency and precision.

1. Precious Metal Melting
   The manufacturing process begins by melting gold, silver, platinum, or other precious metals using high-efficiency induction melting furnaces that ensure uniform temperature control and minimal metal loss.
2. Continuous Casting
   Molten metal is transformed into bars, rods, strips, or billets using continuous casting systems that provide consistent material quality for downstream production.
3. Rolling & Wire Drawing
   Rolling mills and wire drawing equipment convert cast materials into sheets, strips, and wires used for jewellery components, chain manufacturing, and fabrication.
4. Jewellery Casting
   Vacuum and centrifugal casting systems produce highly detailed jewellery components with excellent surface finish, reduced porosity, and precise dimensional accuracy.
5. Precious Metal Refining
   Gold and silver refining systems remove impurities to produce high-purity precious metals suitable for jewellery manufacturing, bullion production, and industrial applications.
6. Electroforming
   Electroforming technology enables the production of lightweight, intricate jewellery designs with exceptional strength while reducing precious metal consumption.
7. Finishing & Polishing
   Professional polishing equipment delivers superior surface finish, mirror polish, and consistent product quality before final inspection.
8. Laboratory Analysis & Quality Control
   Advanced laboratory instruments ensure precise metal composition analysis, quality verification, and compliance with industry standards.

Frequently Asked Questions

What machinery is required to start a jewellery manufacturing factory?
A complete jewellery manufacturing facility typically includes induction melting furnaces, continuous casting machines, rolling mills, wire drawing machines, vacuum casting systems, polishing equipment, refining systems, laboratory instruments, and precious metal recovery equipment. The exact machinery depends on production capacity and manufacturing processes.

What is the difference between melting and casting?
Melting is the process of heating precious metals until they become liquid. Casting is the process of pouring molten metal into molds or continuous casting systems to produce bars, rods, jewellery components, or finished products.

Which machine is used for manufacturing gold bars?
Gold bars are manufactured using induction melting furnaces combined with specialized gold bar casting machines designed to produce investment bars, bullion bars, and ingots with precise dimensions and high surface quality.

Can Delmer Group supply complete turnkey jewellery factories?
Yes. Delmer Group provides complete turnkey jewellery manufacturing solutions, including machinery selection, plant layout, installation, commissioning, operator training, and technical support.

Which precious metals can be processed using your machinery?
