In the era of Industry 4.0, digital fixture management is transforming how manufacturers achieve standardization, efficiency, and reliability—especially in high-stress environments like steel production. This article explores the case of Dalian Tiding Heavy Industry’s self-developed power-driven slab clamp, leveraging Siemens Teamcenter PDM for full lifecycle data tracking and MSC NASTRAN simulation for structural optimization and thermal deformation control. By integrating digital tools into fixture design, validation, and reuse, the company reduced rework by 15% and extended clamp lifespan by 30% under extreme temperatures (above 1200°C). Real-world performance metrics, technical diagrams, and implementation steps demonstrate how building a structured fixture knowledge base drives smarter manufacturing decisions. Whether you're in automotive, metalworking, or heavy industry, this approach offers actionable insights for scaling automation while maintaining precision. Ready to optimize your fixture strategy?
