In the automotive manufacturing sector, stamping is a core process for producing body panels (e.g., doors, side panels, engine hoods). Traditional stamping lines rely on manual loading/unloading, facing challenges such as low efficiency, harsh working conditions (noise, high temperatures, dust), safety risks, rising labor costs, and a shrinking workforce of young workers. Market research indicates increasing adoption of industrial robots in stamping, especially amid the rapid growth of new energy vehicles (NEVs). Heavy payload, high precision, and high stability in stamping automation solutions have become critical for automakers to reduce costs and enhance efficiency.

Addressing industry pain points, Estun has successfully delivered China’s first fully domestically developed heavy-duty robotic automotive panel stamping line, marking a major breakthrough in domestic stamping automation technology. This solution integrates full-line control, covering the entire process from destacking, cleaning, stamping, to material handling. For NEV body manufacturing, the solution resolves issues like unstable cycle times and material waste caused by delayed equipment responses and inefficient process transitions through high-precision positioning and multi-robot collaboration, supporting automakers in achieving lightweight and carbon-reduction goals.

Heavy-Duty Stamping Line Turnkey Solution

Estun, with 30 years of expertise in stamping automation, has built full-chain capabilities from core components to turnkey integration. Its self-developed ER150-3200-PR heavy-duty stamping robot is designed for automotive panel stamping and other high-payload scenarios.

Ultra-High Payload & Adaptability: Optimized wrist inertia allows handling of large panels, multi-sheet stacking, and wide press spacing, meeting automotive industry demands for efficient large-panel handling.

High-Speed Precision Motion Control: Customized kinematics and proprietary dynamics algorithms optimize stamping trajectories, achieving cycle rates of 10-12 strokes per minute (SPM), significantly boosting line efficiency.

Stability & Reliability: Rigorous endurance testing ensures continuous high-speed operation without failure, meeting 24/7 high-intensity automotive production needs.

Hardware-Software Synergy: Estun’s proprietary stamping software suite and press control system (PAC series) enable synchronized line control and flexible process parameter configuration, reducing debugging complexity.

Master Control System Empowers Efficient Manufacturing

Estun’s domestic heavy-duty robotic stamping line master control system serves as the intelligent core, coordinating robots, presses, and auxiliary equipment via an integrated control architecture. It centralizes real-time data (press signals, robot statuses, safety interlocks) for dynamic decision-making, enabling closed-loop management from order parsing, recipe calling, production execution, to safety monitoring. This ensures seamless coordination across destacking, stamping, and handling processes.

Smart Scheduling & Collaborative Control: Automatically adjusts cycle times for product variants and mold changes to maximize equipment utilization. Synchronizes robot, press, and conveyor actions for multi-device coordination, boosting line efficiency.

Real-Time Monitoring & Proactive Maintenance: Networked monitoring and AI algorithms track equipment data and part locations, enabling rapid anomaly response via threshold alerts and fault prediction. Remote troubleshooting and software updates minimize downtime.

Data-Driven Optimization: Matches process parameters to orders for precise production execution. Records yield, energy consumption, and OEE (Overall Equipment Effectiveness) metrics, generating visual reports to support process refinement and resource planning.

Multi-Layer Safety Protection: Combines light curtains, safety PLCs, role-based access, and redundant data design to prevent errors and failures, ensuring personnel and equipment safety.

Digitalization Builds Smart Stamping Ecosystem

Estun’s digital stamping line integrates order management, equipment status, and efficiency data for real-time processing and visualization. Edge computing and the E-Noesis industrial platform enable precise equipment management, lean production, and rapid after-sales support.

Real-Time Stamping Equipment Monitoring: Displays part names, daily targets, current output, cycle times, and batch pass rates, driving dynamic optimization for visible and controllable production.

Robot Status Tracking: Monitors robot states (running/stopped/emergency stop/alarm), operation modes (step/continuous), and speed adjustments to standardize operations and reduce downtime.

Press Stability Assurance: Tracks press statuses (running/stopped/emergency stop/alarm) and operation frequency to ensure stable performance.

Efficient After-Sales Support: Edge-to-cloud data analysis enables remote diagnostics and maintenance guidance, shortening response times and cutting costs.

With self-developed core technologies and agile local service, Estun leads China’s industrial robot market, ranking first among domestic brands in 2024. Its stamping solutions are expanding across automotive, home appliance, and hardware industries.

Estun’s heavy-duty stamping line not only fills the gap in domestic high-end stamping equipment but also drives automotive manufacturing toward intelligence and sustainability. As domestic robotics technology advances, Estun is poised to carve a new chapter in global competition.
