Manufacturing of Door Thresholds at Internorm – Fenster GmbH

In the diploma thesis entitled Manufacturing of Door Thresholds at Internorm – Fenster GmbH, the student researched the production process of door thresholds and focused on optimising production technology at Internorm. In the final work, the student proposed further steps for optimising the threshold manufacturing process, such as introducing new machines for automated material cutting, which would reduce the amount of waste and increase cutting precision. Internorm could also improve logistics processes and energy efficiency.

Solution and Method

In the diploma thesis entitled Manufacturing of Door Thresholds at Internorm – Fenster GmbH, the student researched the production process of door thresholds and focused on optimising production technology at Internorm. As the leading European manufacturer of windows and doors, Internorm faces constant challenges to improve its products in order to meet high market standards. The work examines in detail the use of the CNC machine Rover A 1532, which is crucial for efficient and precise processing of thresholds, as it enables multi-axis machining and the use of advanced software for optimisation and automation of industrial processes.

In the introductory part, the student presented the basic challenges in threshold production, which are an important element for ensuring energy efficiency and functionality of door systems. When analysing the production phases, the student found that the transition from aluminium to glass fibre reinforced plastic (GFK) brought numerous advantages. GFK provides better insulation properties, lower weight and greater resistance to corrosion, which contributes to the durability and quality of the final product in the long term.

The CNC machine Rover A 1532 plays a key role in the threshold manufacturing process. The machine supports precise processing of various materials and enables a high level of automation, which increases productivity, reduces waste and the need for manual work. With advanced software, the machine can be integrated into existing industrial processes, which increases its efficiency and enables smooth workflow without additional intervention.

This reduces labour costs, improves product precision, whilst also lowering energy consumption.

Results

In the final work, the student proposed further steps for optimising the threshold manufacturing process, such as introducing new machines for automated material cutting, which would reduce the amount of waste and increase cutting precision. Internorm could also improve logistics processes and energy efficiency. The student believes that these improvements would further increase the company's competitiveness, reduce costs and contribute to more sustainable operations.

With this work, the student wished to contribute to improving the understanding of the importance of new technologies and materials in the building joinery industry, whilst also emphasising the sustainable advantages of using GFK materials. With these improvements, Internorm strengthens its position as an innovative and environmentally oriented manufacturer of windows and doors.
