Sometimes a new machine is not necessary. Well-maintained production machines, whose mechanical components have been regularly maintained, are often an effective alternative to buying new machines. Through retrofitting, only the electrical drive and automation components need to be replaced to ensure system availability. Retrofitting is therefore the cost-efficient alternative to new investments. Depending on the performed scope, a state of the art system functionality is achieved. Operator safety together with compliance to the latest EU standards for machine design can be part of the Retrofit as well.
