Equipment That Keeps The Gold And Silver Inside Your Factory
Electroforming, plating, gold and silver salt production, acid finishing and precious metal recovery, built for jewelry manufacturers and refiners. Every machine on this site publishes what it actually does: 9999 silver from 92.5 percent scrap, 99 percent recovery out of spent plating solution, 68.3 percent gold potassium cyanide made on your own floor.

What we build
Five Equipment Families For Precious Metal Production
Recovery and refining, gold and silver salt making, electroforming, plating bath equipment and acid finishing. Each family is organised around a decision a jewelry plant or a refiner actually has to make, not around a catalogue structure.
5 machines
Gold/Silver Potassium Cyanide Making Machine
Gold and silver salt production by diaphragm electrolysis, plus the stripping, electroforming and plating machines grouped with it on the source site.
2 machines
Precious Metal Electroforming Equipment
Cyanide-free 24K hard gold and nickel sticker electroforming, both under PLC or timed control.
1 machines
Electroplating Equipment for Jewelry
Bath filtration that keeps plating thickness, brightness and adhesion inside specification.
1 machines
Safe Acid Burning & Color Hanging Cabinet
The most dangerous process in a jewelry factory, enclosed and with 98 percent of the fume treated.
The range
Ten Machines From Across The Catalogue
Two from each family, so the way the specifications are written is visible before you click. All 15 are on the machines page, on one page, with nothing held back.

Metal Nickel Sticker Electroforming Machine
Four tank sizes from 100 to 180 litres for electroformed nickel labels, logos and nameplates.
80 L/min
Chemical Liquid Medicine Filter
Glandless circulation filter that keeps a plating or electroforming bath clean while it runs.
>98% purify
Automatic Safe Acid Burning and Color Hanging Cabinet
Heated sulfuric and nitric acid work behind a closed door, with 98 percent of the fume treated.
Who we serve
Six Industries That Run This Equipment
Jewelry manufacturing is the core, but the same electrolytic and adsorption processes are what e-waste processors, plating shops, imaging labs and refiners use to get metal back.
Jewelry Manufacturing
Electroforming, plating, acid finishing and scrap recovery for factories making gold and silver pieces.
Electronics And E-Waste Recycling
The urban mine: gold, silver, palladium and platinum recovered from boards, connectors and leach liquor.
Electroplating And Surface Finishing
Bath cleanliness, drag-out recovery and de-plating for plants running precious metal baths.
Photographic And Imaging
Silver pulled out of spent fixer at 98 percent recovery, with residual below 20 mg/L.
Precious Metal Refineries
From mixed feed to a documented purity figure: 9999 silver, cathode copper, aqua regia gold dissolution.
Signage And Nameplate Manufacturing
Electroformed nickel labels, logos and trademarks from a screen-printed stainless master.
What we solve
The Four Problems Behind Almost Every Enquiry
None of them is solved by buying a cheaper machine, and all four are answered on the individual machine pages rather than in a phone call.
Metal Leaving The Building As Waste
Drag-out tanks, strip solutions, rinse waters and spent fixer all carry gold and silver at concentrations nobody bothers with. Electrolytic recovery reaches 99 percent or better on gold and silver; resin adsorption picks up what is too dilute for that, above 98 percent.
Scrap Sold At Somebody Else's Assay
Silver at 80 to 92.5 percent goes to 9999 on 10 percent dilute nitric acid alone. Copper at 80 percent comes out as cathode at up to 99.99 percent, with the electricity budget published at 3000 to 3500 kWh per tonne.
Gold Salt Bought In At A Margin
Gold potassium cyanide at 68.3 percent purity made in-house by diaphragm electrolysis, with the tank leak-tested repeatedly because the liquid in it is dissolved gold, and filter cotton on the exhaust so the fume does not take any with it.
A Fume Problem The Inspector Has Noticed
Acid gas purification with pH control rated above 98 percent on the acid burning cabinet, 99 percent on the titanium reactor with its matching purifier, and an integrated extraction, spray and recovery cabinet on the silver salt machine.

Knowledge centre
Process Guides, Not Brochures
Why chemical silver displacement tops out at 70 to 80 percent recovery, where the gold actually sits inside a scrap motherboard, and how karat value is held at 75 percent through an electroforming bath.
Process guide
Silver Recovery From Waste Fixer Solution
Waste fixer carries 3 to 6 grams of silver per litre. Why chemical displacement only reaches 70 to 80 percent recovery, and how electrolysis gets past 98 with residual below 20 mg/L.
Process guide
Recovering Precious Metals From Electronic Scrap
One tonne of phone motherboards holds 200 to 350 grams of gold. Where it sits, what chemical gold removal powder actually achieves, and where electrolytic recovery takes over.
Technology guide
18K Electroformed Gold: Advantages, Process And Market
A solid 18K necklace at 50 grams becomes an electroformed one under 25. How karat value is held at 75 percent through the bath, and where the 20 to 50 percent cost saving comes from.
FAQ
Questions Buyers Ask First
What does Xinhongfa actually make?
15 machines in five families: precious metal recovery and refining, gold and silver potassium cyanide making, electroforming, electroplating bath equipment, and the safe acid burning and colour hanging cabinet. Every one publishes its specification on this site.
Do you customise?
Yes. Full customisation is offered on machine size, capacity and functions. Copper refining anodes are made to your drawings and electroforming fixtures are made to the actual piece.
What is the lead time?
Production and delivery normally take 7 to 15 working days after the order is confirmed. Customised machines vary with complexity.
Can you ship to my country?
Yes. Global shipping by sea, air or express courier from Shenzhen, on EXW, FOB, FCA, CFR, CIF, DDP or DDU terms.
What certifications do you hold?
2 invention patents and 3 utility model patents, recognition by the Guangdong Environmental Protection Industry Association, and an invention patent verification listed against the acid burning cabinet. No ISO or CE certificate is published, and we will not claim one.
What after-sales support is there?
Online technical support, installation guidance and lifetime after-sales service, with training materials and operation manuals provided. Overseas engineer attendance is stated for the gold melting reactor; confirm it for your specific machine.
