Doit Industries, a pioneer in jewelry machinery and process innovation, has once again raised the bar for the precious metal industry. With an impressive lineup of cutting-edge systems — from chemical conversion to recovery — the company is redefining what efficiency, precision, and sustainability mean in modern jewelry manufacturing.

At the heart of this evolution lies a deep understanding of how every stage — from refining gold to finishing jewelry — contributes to both quality and profitability. Doit’s newly launched technologies are designed to simplify these processes while achieving unparalleled consistency and yield.

Gold Salt Plant — The Foundation of Pure Electroplating

The Doit Gold Salt Plant represents a milestone in chemical processing technology. Engineered for the production of Gold Potassium Cyanide (GPC), a vital raw material in electroplating, this system converts pure gold sheets into high-purity GPC crystals. Through a carefully controlled chemical reaction with cyanide and oxidizing agents, it ensures superior purity and stability — a game-changer for precious metal manufacturers seeking reliability and accuracy in their production chain.

Surface Brightening System — Redefining Brilliance

Casted gold jewelry often carries a rough, matte surface that masks its true beauty. The Doit Surface Brightening System changes that. Specially crafted for intricate designs, it eliminates the coarse layer formed during the lost-wax casting process, revealing a naturally radiant finish. For manufacturers, it means faster finishing, reduced manual intervention, and a consistent sheen that enhances the value of every piece.

Precious Metal Recovery Plant — Sustainability Meets Profitability

In an era where resource recovery defines competitive advantage, the Doit Precious Metal Recovery Plant leads the way. It recovers gold and other precious metals from rinse water, plating baths, and acid wash discharges — transforming what was once waste into valuable material. The system not only reduces environmental footprint but also strengthens profit margins by reclaiming assets that would otherwise be lost.

Gold Forming Plant — Excellence in Every Layer

Compact, efficient, and engineered for perfection, the Doit Gold Forming Plant brings precision electroplating to small and medium-scale jewelry workshops. It combines advanced gold forming technology with stable rectification, precise dosing, and high-efficiency heating. The result is uniform deposition and consistent gold thickness across all surfaces — ensuring a flawless finish and long-lasting brilliance with minimal operational complexity.

Gold Recovery A Machine — Smart Filtration, Smarter Savings

Gold recovery has never been this efficient. The Gold Recovery A Machine employs a premium-grade resin that captures 99.99% of gold from wastewater — even from trace amounts. With a polypropylene body built for durability, this filtration system supports a loss-free recycling process, helping manufacturers recover maximum value while maintaining clean, sustainable operations.

A Vision for the Future

“Our mission is to empower manufacturers with intelligent systems that combine performance, sustainability, and profitability,” says Bhavik Shah, Director of Doit Industries. “Each of these machines represents a step toward smarter production — where every gram of gold, every drop of solution, and every unit of energy contributes to long-term value creation. This is not just technology — it’s the future of jewelry manufacturing.”

With this new range, Doit Industries continues to strengthen its legacy as a trusted innovator in the global jewelry machinery market — transforming production lines into cleaner, more efficient, and more profitable ecosystems.
