Overview
Stürtz Maschinenbau GmbH is a leading German manufacturer of PVC and aluminum window production machinery with over 70 years of industry expertise. Headquartered in Neustadt/Wied-Rott, Germany serving the global fenestration industry through subsidiaries in the USA, Canada, Poland,UK, and China. Following acquisition by Italy's Voilàp Group in September 2025,Stürtz is positioned for accelerated growth with a clear strategic mandate:becoming the industry's strongest after-sale service-support provider.
However, their legacy documentation system couldn't support this ambitious vision. With technical manuals spanning 200G Bacross 8+ languages and service operations covering 60+ global markets,Stürtz's support infrastructure was creating critical bottlenecks that threatened customer retention and revenue growth.
Challenges
Stürtz faced severe operational inefficiencies and documentation chaos that threatened customer retention and revenue growth.
- Inefficient Information Retrieval: Service technicians spent 30–45 minutes per incident searching fragmented documentation (200GB across 8+ languages) in fragmented PDF manuals, spreadsheets, and legacy systems.
- Customer Risk: This delay risked 20–30% customer churn, translating to a potential $13–20M in annual revenue loss.
- Siloed Knowledge: The manual support infrastructure lacked intelligent search capabilities, preventing 24/7 global support.
- Scalability Issues: The legacy system could not scale to support the Voilàp Group's smart factory vision or integrate with existing platforms like StürtzCloud.
- Operational Strain: Required significant personnel resources to manage multilingual documentation across diverse machinery portfolios (e.g., LinearPro, FlexCenter, Turbo Welders, OpticTwinStar-3D cleaners).
Solution
Ankercloud designed a serverless RAG architecture to transform documentation access and delivery.| AWS Service | Function in RAG Architecture | AWS Bedrock | Used Claude and Titan foundation models for multilingual embeddings and intelligent response generation. Titan Multimodal Embeddings enabled processing of technical diagrams and schematics. || Amazon OpenSearch Serverless | Provides vector search across 200GB of indexed technical content with sub-second retrieval times. Chosen over Amazon Kendra for 93% cost savings. || AWS Lambda | Orchestrates the complete RAG pipeline, processing 5M+ monthly requests for ingestion, query handling, and response generation, enabling automatic scaling. || Amazon S3 | Stores technical manuals with Intelligent-Tiering for cost optimization. || Amazon DynamoDB | Manages conversation history and session data with on-demand capacity. || Amazon API Gateway | Provides RESTful endpoints for integration, with built-in throttling and caching.
The solution seamlessly integrates with Stürtz's existing StürtzCloud IoT platform, delivering unified technical knowledge across all customer touchpoints.
Business Outcome
The transformation delivered measurable results in operational excellence and strategic positioning.
