Automated laser loading and unloading pays for itself when the value it creates exceeds the additional cost of owning and operating it. That value may come from more output, fewer subcontracting costs or more usable capacity elsewhere in the workshop.
The calculation should begin with measured handling delays. A system can release hours without reducing payroll, and extra cutting capacity has value only when there is work to fill it. Keeping those distinctions clear makes the investment easier to assess.
Measure the current process
Record a representative week of laser production. Note the number of sheets processed, time spent loading and unloading, and waiting caused by unavailable staff or lifting equipment. Include material changes and clearance of finished nests.
Separate operator time from machine idle time. An operator might spend ten minutes handling a sheet while cutting continues on the other shuttle pallet. Removing that work could release labour without recovering ten minutes of laser capacity.
Use the delays that actually restrict production. If the machinery has no scheduled work, more reliable loading may still help, but it will not create demand.
Decide how recovered time will be used
There are several possible sources of financial benefit. Avoided overtime is a direct saving if those hours are genuinely displaced. Avoided subcontracting can also be valued after allowing for the cost of producing the work internally.
Additional capacity should be valued using contribution, meaning sales income less the variable costs of that additional work. Revenue alone overstates the benefit because material, gas and other costs still have to be paid.
Released operator time can be valuable when it removes a constraint elsewhere. If it simply changes how an existing employee divides the day, describe it as a capacity benefit rather than claim an immediate wage saving.
A worked example using illustrative figures
The following figures demonstrate the method. They are not a Selmach quotation or a predicted return.
Suppose a workshop identifies five minutes of recoverable machine waiting per sheet across 30 sheets a day. The potential recovery is 150 minutes, or 2.5 hours daily. Across 220 working days, that represents 550 hours annually.
Assume only 70% of those hours can be filled with additional orders. That gives 385 productive hours. If those orders generate £60 contribution per machine hour, the annual contribution is £23,100.
If the automation adds £4,000 in annual operating and servicing costs, the net annual benefit is £19,100. An illustrative installed investment of £80,000 would have a simple payback of approximately 4.2 years: £80,000 divided by £19,100.
The example excludes finance charges, tax effects and changes in working capital. It also assumes the quoted benefits can recover the measured delay without creating another bottleneck. Those assumptions must be tested before using the result for a purchase decision.
Avoid counting the same benefit twice
If the extra capacity produces additional orders, do not automatically add the same hours again as avoided overtime or subcontracting. Establish which work is moving into each recovered hour and what cost or contribution changes as a result.
The same caution applies to operator time. An employee operating another machine while the laser runs may improve output, but that benefit should be counted against the work completed there, not described again as a wage reduction.
A transparent calculation can be less impressive than a headline saving, but it is more useful when the business has to commit funds.
Include the full cost of installation
Allow for the equipment, installation, any required machine changes and site preparation. Add training and commissioning wherever they are material to the project.
Running costs may include electricity, servicing, replacement handling components and insurance changes. Extra production also requires material purchases and downstream capacity. If bending or welding is already full, additional cut parts may create work in progress rather than invoiced output.
The Compact Tower and Full Tower System provide configurations to investigate, with final costs and suitability established through a quotation.
Test a cautious scenario before committing
Repeat the calculation with fewer recovered hours, lower utilisation and higher operating costs. Check whether the investment remains acceptable during a quieter period and whether a smaller system would address most of the same delays.
