Retrofit or new machine: when it pays to modernise

A machine that has fallen short doesn't always have to be retired. Often the mechanics are still solid and what fails is the control: obsolete electronics, no spare parts, no current safety and no data. In those cases, a retrofit can give you years of service life for a fraction of the cost of a new machine.

When it pays to modernise

• The mechanical base is sound: structure, drives and process elements in good condition.
• The bottleneck is the control: discontinued PLC, old HMI, undocumented wiring or an out-of-date CE marking.
• You want data: add traceability, alarms and history to a "dumb" machine.
• You need more throughput and it can be achieved by optimising control and automation, without rebuilding the machine.

In a recent project, the optimised redesign of a complex packaging machine cut its cost by 16.7% while keeping performance. In another, a modernised filler went from 4,500 to 6,500 bottles per hour without replacing the machine. The mechanics were fine; the margin was in the control.

When a new machine is better

• The mechanics are worn or the design has nothing left to give.
• The process has changed so much that the machine no longer fits.
• The retrofit cost gets too close to that of a new machine.

The decision isn't ideological, it's economic and technical: how much service life you gain, at what cost and with what risk. Before recommending one option or the other, we study your machine and give you numbers, not a sales pitch.
