We offer complete minting production lines containing more than 120 machines that allow to manufacture products made out of silver and gold. They were used for manufacturing of: numismatic and investment coins, bullion bars and medals – all made out of precious metals.

The production is currently suspended and the complete minting machinery lines are available for sale. The factory equipment was previously operated by a private mint, which successfully offered its products in EU and USA. Production can be resumed immediately.

 

NOTICE:

  • The factory stopped production in 2015 for reasons not related to the activities of mint itself but other causes.

1. Finished products

  • investors in physical precious metals
  • coin collectors, numismatist
  • common individuals investors

2. Minting service

Designs of the products

1. Old designs

The license for old designs that mint has been manufacturing are not contained in this offer and have to be negotiated separately. There is also scope for cooperation on manufacturing these designs as a minting service.

2. New designs – it’s easy!

1111 111111When you wish to design a new coin you need to contact a designer to prepare the new design. The ArtCAM software is perfect for such job and it is popular. It takes few days for a skilled graphic designer to transfer your idea into the .ART file (approximate cost: 300EUR).

The new design is engraved within 4 days on a blank stamp. It can be done by a CNC machine, but the best quality can achieve 3D engraving laser (approximate cost: 200EUR). We are ready to reveal all the details about this process and help you with the first designs.

Silver supply

The biggest producer of silver in the world is a mining company KGHM. It is located in Poland just 550km from the mint. For the minting purposes silver grain of high purity 99,99% was usually used. Raw materials were sometimes supplied also from Netherlands.

Machinery for sale

Picture of the offered machines are here, if you have any questions let’s get in touch.


Production processsilv

The raw material from the supplier usually comes as a silver or gold grain. It takes 10-12 stages and a group of machines to manufacture a final product (either a coin or a bar):

1. Melting the raw material into a stripe (there are 5 induction melting furnaces; 3 of them are continuous casting furnaces

Figure 4. Non-continuous melting is good for small quantities or prototype development

2. Etching of metal, chemical cleaning and ultrasonic cleaning of the material.

3. Rolling a stripe to decrease its thickness (rolling machines)

This process is necessary to decrease the thickness of stripes. Rolling has to be done many times, each time the stripe should be a little bit thinner to achieve a suitable thickness – and thus appropriate weight of the coin/bar. At the moment 5 rolling machines is ready for action.

4. Coining

At this stage eccentric punch press is cutting a blank coin/bar out of a stripe. There is a wide range of dies that can cut different sizes and shapes.

There are 15 eccentric punch presses with various dies mounted.

5. Weight control

Blank coins and bars required to be weighted to ensure that it consist a correct amount of material.

6. Tempering At this point the blank coin/bar is very hard.
During tempering process hardness of metals is reduced and it will be easier to impress a design on blanks.

Products are heated to a high temperature in a special furnace with a conveyor belt and the ambient gas (often a mixture of hydrogen and nitrogen).

7. Edge/rim adjusting. For bigger sizes of coins often required to uplift their rim-edge on an upsetting machine (also known as a rimming machine).

8. Acid cleaning

This clears out any oils and fats from the machine or hands of employees.

9. Drying 

10. Pressing a design

At this point a clean blank coin/bar is placed in a tooling of a hydraulic press. A weight of up to 130 ton is impressing the design from a lower and upper stamps into a silver coin (or other product).

Hand casting

For small quantity of products or when a new design is developed a hand casting can be employed. The equipment for this process is ready. Below are few of the products made in the mint:
