WiN - woodworking INTERNATIONAL is the international magazine for the woodworking industry. We report on all aspects of woodworking from board materials, wood treatment to machines, tools and technical know-how, from timber engineering supplies to the latest developments in technologies and markets. We address factory managers and production engineers directly, and thus ensure coverage of the decision makers within the industry.

WINDOWS Planning and

WINDOWS Planning and automating with a system requires a great deal of intuition – tomorrow’s manufacturers must already take this into account today Hardly any other sector within the wood and plastics processing industries is currently exposed to such strong changes as the window and door sector. The market for construction elements has grown with the increasing construction boom of recent years and the demand for window and door systems remains high. However, a wide variety of factors, such as advancing climate change, the increased use of natural resources, rising construction costs, security concerns, design trends and functionality, are having an enormous impact on the demands that end consumers are making on their future living space. We could almost say that the benchmark for building or renovating a house is almost limitlessly high. But – what is the benefit of a building built according to the most modern aspects if the windows or doors available on the market are not at least as modern? Two main trends are apparent here and thus set the trend that manufacturing companies will have to take into account in the future with regard to their product range. “Climate protection through sustainable and environmentally responsible building” The protection of the earth’s climate is more in focus today than ever before. The goal of replacing fossil fuels, reducing energy consumption in the home and increasing the use of natural raw materials is attributing a particularly important role to windows and doors in construction. Therefore, highly insulating window systems made of the renewable, sustainable frame material wood are becoming increasingly popular. Weather extremes are apparently occurring more frequently, which is why the demands on window systems are increasing. In the future, future-oriented window and door systems will have to fulfil the highest technical properties, such as resistance to wind load, impermeability to driving rain, air permeability or optimal thermal values. And all this with the highest ease of use, maximum safety and long material durability. “Compact but nevertheless comfortable living space” The trend towards space-saving construction, for example of so-called Tiny Houses, can currently be seen all over the world. Rising land and building costs, population concentration, alternative life planning or the low availability of building materials – the reasons for this building trend are manifold. The fact is, however, that the deliberately minimised use of space simultaneously places special demands on the functionality of windows and doors. Here, for example, systems are required that do not additionally restrict the limited living space. Variable and flexible window and door systems, designed as sliding elements or as outward-opening constructions, or systems with particularly large glass clearances are not only very popular for this building trend. The direction for windows and doors is therefore set and the market is beginning to change. And right now this can be a real dilemma. Increasingly, window and door manufacturers are asking themselves how the expectations of the market can be translated into suitable products and, even more importantly, into entrepreneurially successful production concepts. After all, it is not easy to give up tried-and-tested products and the associated successfully implemented processes. Apart from not insigni- ClimaTrend Style from Leitz (shown here in wood and wood/aluminium versions) is a modular, future-proof window system. It combines modern, linear design with maximum functionality and security. (Photo: Leitz) Climate protection through sustainable and environmentally conscious building.

WINDOWS ficant financial risks, it is primarily economic framework conditions, such as the situation on the labour market or scarce material resources, that make the ideal path to change so difficult to identify and challenging for so many people. Solution approach 1: The future is a window system solution Raw material, cost and price developments, skilled labour, control technology, machine and tool technologies – all these terms represent factors that influence a production plant. However, if several factors come into action at the same time, as for example in the case of a change in the product portfolio, entrepreneurial success is clearly at risk. One approach to a solution is therefore the use of tested systems. In the course of their development, all these factors have already been taken into account and, with a view to the long-term development of construction trends, such products last significantly longer on the market. For example, in order to take into account the rising prices of raw materials and to ensure sustainable, cost-secure production, it is a question of the raw material for the customer product, i.e. the window and door systems themselves, on the one hand, and the materials required to manufacture it, on the other. Systems that allow for small face widths and thus manage with small material dimensions, such as the ClimaTrend Style window system from Leitz, therefore offer clear advantages. In addition, this externally tested system fully meets requirements such as high burglar resistance, maximum insulation and impermeability. ClimaTrend Style can be produced in various construction depths and as a timber and timber/aluminium system. Its modular design – which means that exactly the same basic profiles are used for timber and timber/aluminium constructions – guarantees the basis for more efficiency and thus less time and costs in production. Solution approach 2: Efficiency through automation The many different requirements for windows and doors can result in quite a large number of different systems. Implementing these successfully and economically within a production process is a particular challenge – especially with smaller batch sizes. The key to success in this regard is provided above all by high-performance machine concepts with a high degree of automation. The performance and production capacity of companies is thus ensured for years to come and processes become significantly leaner or less personnel-intensive. In times of acute shortage of skilled workers, this can be a significant competitive advantage for manufacturing companies. However, such modern machine concepts also require powerful tools to guarantee a highly efficient overall package. After all, it is the tool that has to implement the efficiency of the machine on the material. Therefore, the same applies here: The more powerful the tool, the higher the economic success in the overall process. Leitz provides the perfect solution in this area with its ProfilCut Q system series and sets the absolute benchmark in the industry in numerous comparisons. It is not only the fastest tool system in the industry in terms of productivity, topics such as resource conservation and sustainability were also taken into account during development. For example, the tools are equipped with specially coated knives. This keeps cutting material wear as low as possible and extends the tool life many times over. With the ProfilCut Q PLUS and ProfilCut Q Diamond systems, Leitz also provides resharpenable, constant-diameter and constant-profile tools that make tool changes even more cost- and timesaving. Leitz also provides a large range of coated solid carbide drills and routers, which are also characterised by durability and perfect machining quality. Solution approach 3: Planning, planning and once again planning When investing in modern production, the concrete planning of the products to be manufactured is often completely underestimated in advance. Questions such as “Who are my customers and what are their requirements?” are asked, but some producers ignore the fact that this also includes the definition of the profile systems required in each case, including the determination of which are the main systems and which window systems are needed to complement the programme in a meaningful way. In addition, the concrete sections including the presentation of all required profile variants must be planned and considered in advance. If questions then arise about the frequency of this multitude of variants, the confusion is usually complete. The good old principle “less is more” should come into use here – but how much less and how much more makes sense in the end overwhelms many planners again. So if you plan as precisely as possible in advance, you will rarely experience unpleasant surprises during implementation and commissioning that cost time, nerves and additional money. Since in the rarest of cases there is an expert for mechanical engineering, software, tool technology and process engineering in every company, it makes sense to work together with partners. Ideally, these should have a correspondingly professional network from all production-relevant areas and also have a lot of knowledge about the interaction of all functional areas. These networks of reliable, experienced partners are the guarantee for every joint project success and a trouble-free implementation of new production systems. Delays or even production downtimes can result in profound economic or even existential problems. Leitz, with its extensive network of technical consultants and its many years of international knowhow, provides the perfect support in such decisive pre-project phases. Another important cornerstone of Leitz’s far-reaching consulting expertise is the regular professional exchange with almost all major suppliers from the window and door industry, such as machine manufacturers, software houses, system houses or fittings, seals and lacquer manufacturers. In addition, reliability is immensely important not only during the project phase, but also afterwards. Leitz provides a wide network of technical consultants and manufacturer-quality service in your vicinity. Ensuring the long-term success of a company is therefore largely based on the choice of future-proof window and door systems in the product portfolio and on cost-effective production, even with small batch sizes, which can be achieved, among other things, through a high degree of automation. www.leitz.org ProfilCut Q Premium is the fastest profile tool system in the industry. The ability to combine disposable and resharpenable constant systems makes the ProfilCut Q tool family unique on the market. (Photo: Leitz) No. 2 • June 2022 13
