Weighing as Quality Control. The weight of every blank, regardless of its shape, is more than a production parameter—it safeguards material value and meets regulatory standards. Precise weighing ensures target weights are hit exactly, reduces waste, and maximizes material efficiency.

The weight of a coin/blank is more than just a parameter in the production, it is a legally guaranteed minimum weight and this ensures the material value.

The target weight of an optimal coin/blank is thus (a few mg) just above the nominal value. Below this, there is the immediate melting of the blank. If this is significantly exceeded, more material will be needed as required.

The 100% precise & accurate weight control in the production process is the only way to optimize the production – so that the objective weight of the coin/blank is followed correctly.

In addition, the weighing offers the possibility to divide the coins/blanks in weight classes and so prepare them for a possible material recovery.

Each weighing line has a special valve system that ensures the discharge of “reject” blanks/coins immediately after weighing. “Reject” in this case means that the desired weight of the respective object was under or over target weight– and thus through discharging the objects are distinguished and ejected separately.

Only when the “reject” blank/coin has triggered a light barrier in the discharge chute, the next blank/coin is weighed. Thus we ensure that no blanks/coins are further processed if the weight does not comply.

It is a good feeling to be able to trust that all products take their right path!

You know the requirement:
tiny products that can only be measured by a laboratory scale.
 
The slightest whiff of air influences the measurement, which is why this scale is completely enclosed. Which means open the door, close the door – make the measurement – and then open the door again in order to remove the product and continue in the process.

We have a more practical solution for this complicated and sensitive process:
An automatic feeding creates the right separation and positioning of your product on the scale. The following weighing process happens with a resolution of 0.0001g and with a repeated precision of +/- 0.0002g. If the measurement shows that the product does not have the desired weight, it will automatically be displaced into the reject area and will not move on to the following production process.
