Premium Interior Solutions

Our development services support you from the initial design right through to production-ready implementation. Whether it’s pattern development, optimisation or industrialisation – we create efficient, process-reliable solutions. Complemented by quality checks and supplier management, we provide comprehensive support for your projects – reliably and cost-effectively.

Technical interior services for efficient mass-production processes

Our interior services cover all phases of technical development – from the precise design of cut-outs, through optimisation for material efficiency, to industrialisation. Through inspection and sorting processes, as well as well-thought-out supplier management, we ensure quality and adherence to deadlines in complex series production projects. This results in robust, production-ready solutions for the mobility sector – efficient, scalable and process-stable.

Our interior design and development services cover the entire process, from the initial concept through to production-ready implementation. Whether it’s pattern development, material optimisation or industrialisation – we support you with in-depth expertise, state-of-the-art CAD technology and practical experience. Complemented by testing, sorting and reworking, as well as professional supplier management, we offer you comprehensive solutions for functional, design-oriented and process-reliable results. Ideal for OEMs who prioritise efficiency, quality and collaborative development.

We develop precise physical cut-outs, which are then digitised and converted into 2D data for high-quality interior components – individually tailored to material properties, component geometry and design specifications. We take the subsequent processing steps into account right from the development phase to ensure maximum process reliability and repeatability. Whether leather, microfibre or technical textiles – our cutting solutions form the basis for cost-effective and quality-assured series production.

Through intelligent layout and area calculation, we improve existing cutting patterns in terms of material utilisation, production speed and waste minimisation. Our optimisation processes lead to significant cost savings and greater efficiency – without compromising on fit, design or function. Particularly when it comes to high-quality materials such as leather or Alcantara, we offer OEMs and suppliers scalable solutions for series production and pre-series projects.

We translate design specifications and prototype solutions into robust, production-ready processes – from the initial test run right through to implementation ready for standard operating procedures (SOPs). In doing so, we tailor the choice of materials, tooling design and manufacturing parameters precisely to your production requirements. With in-depth process knowledge, interdisciplinary coordination and OEM-compliant documentation, we lay the foundations for smooth, quality-assured production. Our aim: the perfect combination of function, design and efficiency.

To ensure the quality of your interior components, we handle sorting and rework processes throughout your supply chain – reliably, systematically and in accordance with OEM standards. We identify defects, sort components selectively according to defined criteria and rework them for immediate reuse. Whether it’s visual inspection, dimensional checks or functional tests: we ensure stable processes and consistent quality – particularly during bottlenecks, recalls or short-notice production runs.

An effective supplier network is crucial to the success of a project. We take charge of the operational and strategic supplier management for your interior design projects – from selection and qualification right through to coordination and communication during the ongoing production process. Through targeted monitoring of quality, on-time delivery and escalation procedures, we ensure the performance of your supply chain. Transparent, tailored to your requirements and fully aligned with your OEM processes.
