Safe automated die storage ASRS

The High Cost of “Business as Usual” in Die Storage

In any automotive stamping plant or heavy machinery facility, the die storage area is often a controlled chaos. Sprawling floor space is consumed by multi-ton dies, creating a hazardous obstacle course for personnel and equipment. The traditional workflow, relying on overhead cranes or high-capacity forklifts, is fraught with inefficiencies and unacceptable risks that directly impact your bottom line.

• Extreme Safety Hazards: The high-altitude lifting of a 10,000-pound die is one of the most dangerous operations in the plant. A dropped load is catastrophic, and the risk of worker injury during rigging and maneuvering is a constant source of anxiety for any plant manager.
• Production Bottlenecks: Locating, rigging, and transporting a specific die can take up to 45 minutes. This prolonged changeover time means your multi-million dollar stamping press sits idle, directly killing throughput and OEE (Overall Equipment Effectiveness).
• Damage to Critical Assets: A slight miscalculation by an operator can lead to a die being bumped, scraped, or dropped. Damage to the precision surfaces of a die set can cost tens of thousands of dollars in repairs and cause significant production delays.
• Wasted Floorspace: The “honeycombing” effect of ground-level die storage is incredibly inefficient. To access a die in the back, multiple others must be moved first, consuming valuable square footage that could be reallocated for value-added production activities.

From High-Risk Lifting to High-Precision Automation: The starack-Heavy System

A safe Die Storage Rack system is not just about racking; it’s a fully integrated piece of Automated material handling equipment engineered for extreme loads and operational certainty. The starack-Heavy Heavy duty ASRS is designed from the ground up to transform die storage from a manual liability into an automated asset.

Engineered Stability: The Foundation of Safety

Our solution begins with uncompromising structural integrity. Unlike conventional racking, the starack-Heavy system is built around a reinforced Double Mast Stacker Crane. The entire structure is fabricated from Q355 high-strength steel and assembled with a fully bolted connection, not welded. This engineering choice is critical because a bolted structure provides superior resistance to the dynamic fatigue and vibrations generated by moving multi-ton loads. Deep-seated ground anchoring ensures that the system remains perfectly stable, even when handling offset loads of up to 17,600 lbs (8,000kg) at heights of over 100 feet. This structural rigidity is what allows the system to achieve a repeatable positioning accuracy of ±3mm, completely eliminating the risk of die collisions within the racks.

Automated Workflow: Predictability Replaces Imprecision

The starack system orchestrates the entire die handling process with robotic precision. When your MES signals a die change, the Warehouse Management System (WMS) instantly identifies the exact location of the required die. The stacker crane then executes the command:

• Smooth & Safe Motion: The crane’s motors are controlled with an S-Curve acceleration profile, ensuring gentle starts and stops that protect the die from any jolts or shocks.
• Optimized Pathing: The crane travels simultaneously in horizontal and vertical axes, taking the most direct diagonal path to the target location, minimizing travel time.
• Seamless Hand-off: The die is retrieved and transported to an outfeed station, where it can be picked up by an AGV or transfer cart for automated Line-side Supply directly to the stamping press.

This fully automated sequence reduces the entire retrieval process from a 45-minute manual operation to a predictable, sub-5-minute automated task, turning your die changeover into a seamless, just-in-time process.
