In the window industry, there are rarely two productions that are alike. Yet most manufacturers face challenges such as: high waste, production bottlenecks and increasing difficulty finding employees for manual labor.

At Nicolaisen, our experience is that the solution is rarely found in one new machine alone. It is found in the whole. It's about asking the right questions: What products are made? What do the processes look like? And not least, what kind of business do you want to have in five years' time?

Data as a compass

Most manufacturers have far more useful data than they realize. Either from sales or directly from production. Even when the data seems limited, a representative product mix can be constructed and broken down to component level. This insight often highlights the most impactful areas of action that can strengthen the business.

With a solid data foundation, it becomes clear whether it's the saw, the assembly or the CNC that needs to be lifted first. The numbers often point the way to the biggest gains.

The hidden engine of profit

Cutting raw wood is a common challenge. In many places, the saw is a major source of waste - but also an obvious place to find savings.

With optimization software, material utilization can be significantly improved. Combined with robots at the outlet, the saw can run fully flexibly while the workpieces are automatically sorted in the right order for the next process. The result is both lower waste - as low as 2 percent - and a noticeable reduction in the carbon footprint.

The manual time waster

If the saw is where the waste happens, the assembly department is where time disappears. Many hours are spent picking up components, assembling frames and installing glass - all very manual work.

Automating repetitive processes such as glazing tapes, seals, fittings and glass assembly is a big win. It frees up time, reduces dependency on manual labor and solves recruitment challenges.

A concrete example is glass logistics: suppliers often charge extra to deliver the glass in the right order. With an automated glass warehouse, sorting can be done in-house - and glass purchases are reduced by around five percentage points.

The balanced factory

A modern window factory doesn't just need to produce fast - it needs to produce in a balanced way.

Robots and intelligent buffers have therefore become a central part of the solution. They can receive parts in any order after the saw, store them and deliver them in exactly the sequence required by the next process. This eliminates bottlenecks, minimizes changeovers and stabilizes throughput.

The key to working with window production is to start with the business - not the machine. The greatest value lies in seeing the entire flow, finding the key areas for improvement and then making an investment plan. Only then does it make sense to choose technology.

The window factory of the future

Two of the biggest potentials today are in:

• - Waste reduction at the saw - through software and robots.
• - Automation in assembly - especially in repetitive and manual processes.

Both areas create quick and measurable results, both on the bottom line, in the carbon footprint and in the work environment.

Window production is still far more manual than many other industries. But it doesn't have to be. With the right focus on data, process and wholeness, the industry can be even stronger in the future.
