General Coin Minting Process

 

There are two stages of coin minting production.  They are material preparation and coin minting.  The whole process of material preparation is then followed by several options of coin minting production.  The process is very much depend on the volume of productions per month and expected life span of the same pattern going to be produced.

 

  • Material Preparation Process Mapping

The schematic video illustrated above shows the material preparation process that acquires the raw material from purified ingot or bar.

 

The raw material is melted with oxygen flame in ceramic bowl.  As the melted material is ready, it is poured into pre-form shaped foundry according to the requirement of the subsequent process.

 

In practice, the raw material is shaped into two types, bar strip as a prerequisite material shape before it is rolled into gold/silver strip, secondly rounded shape coin, which is ready to be used for coin minting purpose.

​

  • Coin Minting

Selection of the minting production equipment (i.e.  appropriate mould, suitable punch, press machine ect.)   very much depends on the volume needed to produce at one instant and the expected product life span for the same pattern.

 

The following illustrations show several options of coin minting steps. They are designed to cater the production capacity, product life span and the security of production, especially to manage the gold and silver residues.

 

Coin minting process involves various types of tooling. The main thing to be considered before deciding on the appropriate process for material selection and coin minting are the ‘forecasted quantity produced per order’ and ‘the estimated product life span’.

 

It should be understood that Dinar and Dirham have their own premium cost, detail cost for every coin feature process involved and the importance of coin standard.
