The Manufacturing Department
In August 2009 the entire manufacturing department, GRC Mint Manufacturing, moved to the Rand Refinery complex in Germiston. It is a far safer environment in which to work with precious metals.
Gold Reef City Mint is one of two privately owned mints in South Africa that have minted legal tender coins. Gold Reef City Mint has been privileged to work on behalf, under license and under the supervision of the South African Mint on a number of occasions.
Gold Reef City Mint is the pioneer in the manufacture of minted precious metal bars in South Africa. Up until recently these bars were only available for export to the foreign market but the new Precious Metal Act that was promulgated in Parliament in July of 2007 now allows local residents to own bars. Gold Reef City Mint has been appointed as one of only two manufacturers permitted to produce bars for the Local market. We have developed a detailed infrastructure for bar production and use a sophisticated “tamper proof” packaging system, which is specified by the Precious Metal Regulator. The minted bars have been a welcome addition to our product range.
We manufacture a variety of coins, medals, corporate gifts, badges, key rings, medallions and trophies. The infrastructure and equipment is well established and enables Gold Reef City Mint to manufacture a vast range of products in a variety of base and precious metals. Gold, silver, and platinum are presently our main focus and specialty.
Over the past twenty eight years, Gold Reef City Mint has developed its ability to operate totally independently. With the exception of packaging materials the Mint is totally self sufficient regarding the design of product, the manufacture of dies and tooling to manufacture blanks and the means to manufacture coins, medals, medallions, minted bars and a large variety of related items. We have our own electro-plating plant on site. The competence of the staff compliment is of a high standard. All our senior staff have undergone extensive training at the South African Mint. All staff members have skills pertinent to the industry and “on the job” training is ongoing.
Gold Reef City Mint has manufactured legal tender coins and medallions for South Africa, Swaziland, Namibia, Zambia, Mozambique and Suriname. We have produced items for the Nelson Mandela Foundation and the F.W de Klerk Foundation. These medallions feature images of both former President Mandela and President de Klerk. We minted the very first medallion ever to bear the image of President Mandela and the first platinum medallion to bear the image of a former President in the form of the F.W. de Klerk Platinum and Gold medallion series.
Although we have more than thirty years of experience in the minting process, in December of 2013 we bought out an entire casting business operation, which now enables us to supply medals at a greatly reduced price compared to the minted medals. We are fortunate to have the services of a foreman that has 15 years experience in spin casting. Our casting department was a natural progression for us to follow and has proven to be very successful.
, also known as centrifugal
rubber mould casting
(CRMC), is a method of utilizing centrifugal
force to produce castings from a rubber mould. Typically, a disc-shaped mould is spun along its central axis at a set speed. At Gold Reef City Mint we manufacture most of our medals, medallion products via this method.
is a method of plastic casting
where a mould
is filled with a liquid synthetic resin
, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. It can be done by amateur hobbyists
with little initial investment, and is used in the production of collectible toys, models and figures, as well as small-scale jewellery production. At Gold Reef City Mint we manufacture most of our resin souvenirs products via this method.
is a manufacturing process in which a wax pattern is coated with a refractory ceramic material. Once the ceramic material is hardened its internal geometry takes the shape of the casting
. The wax is melted out and molten metal is poured into the cavity where the wax pattern was. At Gold Reef City Mint we manufacture our silver Big 5 figurines this method.
Our various departments all produce products that are very well suited to the tourism industry. The expertise and experience that our manufacturing departments have gained over the past 28 years allows us to manufacture “almost anything”. We manufacture jewellery using precious metals and base metals. We cast in bronze, white casting metal, resin castings and produce figurines, key rings, lapel badges, plaques, clocks, fridge magnets, cutlery, glassware and a list of other items, too vast to itemize. We supply personalized products in all the above including caps, hats and other apparel.
We service the entire country including all the major tourism areas like the Western Cape, the Eastern Cape, KwaZulu Natal, Mpumalanga, the Northern Provence and Namibia.
Our retail division concentrates on the corporate, schools, and the international and local tourists destinations. We offer and market the complete range of coins, medals, medallions corporate gifts, promotional items, corporate branded clothing, trophies and tourism related souvenirs.
