Model material losses

To illustrate material loss modelling, let's take the case of a PET component weighing 7g. During manufacture, a loss of 3g is recorded, so a surplus of material must be introduced into the model to account for this loss.

Please note! When accounting for drilling losses, some processes already include the material. In this case, it is not necessary to add excess material as an input for the component.

1. Create the component

Enter the final weight of the component after manufacture (7g).

1. Add excess material

It is possible to enter a mass of input material greater than the mass of the component.

In the model, you must enter the total mass of materials used as input, equivalent to the sum of the component mass (7g) and the mass of production waste (3g), i.e. 10g in our example. The injection process is applied to the component and not to the waste, so the value to be entered is 0.007kg (7g).

1. Transport modeling

Supply takes into account the mass of materials prior to component production (100g). Distribution is associated with the component after manufacture (7g), without the mass of material losses.
