Production of door thresholds at Internorm – Fenster GmbH

In my diploma thesis entitled Production of Door Thresholds at Internorm – Fenster GmbH, I examined the production process of door thresholds and focused on the optimisation of production technology at Internorm. As a leading European manufacturer of windows and doors, Internorm faces the constant challenge of improving its products in order to fulfil the high market standards.

My thesis examines in detail the use of the Rover A 1532 CNC machine, which is central to the efficient and precise machining of door thresholds, as it enables multidimensional machining and the use of advanced software to optimise and automate industrial processes.

In the introductory section, I outlined the fundamental challenges in the manufacture of door thresholds, which are a key element in the energy efficiency and functionality of door systems. When analysing the production phases, I found that the switch from aluminium to glass fibre-reinforced plastic (GRP) brought numerous advantages.

GRP offers better-insulating properties, lower weight and higher corrosion resistance, which contributes to the long-term sustainability and quality of the end product.

The Rover A 1532 CNC machine plays a key role in the door threshold manufacturing process. The machine supports the precise processing of various materials and enables a high degree of automation, which increases productivity, reduces waste and minimises manual effort.

Thanks to the advanced software, the machine can be integrated into existing industrial processes, which increases its efficiency and enables a smooth workflow without additional intervention. This reduces labour costs, increases the precision of the products and reduces energy consumption.

In the conclusion of my thesis, I proposed further steps to optimise the manufacturing process, such as the introduction of new machines for automated material cutting, which would reduce waste and increase the accuracy of cutting. Internorm could also improve its logistical processes and energy efficiency. I believe that these improvements would further increase the company’s competitiveness, reduce costs and contribute to a more sustainable operation.

With this work I wanted to improve the understanding of the importance of new technologies and materials in the building supply industry and at the same time highlight the sustainability benefits of using GRP materials. With these improvements, Internorm strengthens its position as an innovative and environmentally conscious manufacturer of windows and doors.
