Your injection molding machines are idle, waiting for a mold change. Expensive molds are cluttered on pallets, risking corrosion and collision damage. There is a systematic way to reclaim valuable floor space, slash your changeover times, and protect your high-value tooling assets. |
In a high-volume plastic packaging facility, the space between your injection molding machines is prime real estate. Yet, for many production supervisors, this area is a chaotic landscape of wooden pallets and floor-stacked tooling. An injection mold storage system that isn't fit for purpose creates daily bottlenecks that directly impact your bottom line. Finding the right blow mold or thermoforming die becomes a time-consuming search, requiring a forklift operator to carefully navigate tight spaces, pushing other molds aside. This process not only extends machine downtime during SMED (Single-Minute Exchange of Die) procedures but also introduces significant risks of collision, damaging the precision surfaces of molds that can cost tens of thousands of dollars to repair.
Furthermore, molds left on the floor are highly susceptible to moisture, leading to rust and corrosion that compromise the quality of your PET bottles, PP cups, or plastic containers. For the die setters and tool room technicians, manually maneuvering these heavy assets with pry bars and excessive force is a serious ergonomic hazard, leading to potential back injuries and worker compensation claims. This disorganization consumes up to 80% more floor space than necessary—space that could be used for another production line or a dedicated mold maintenance area.
A purpose-built heavy duty mold rack is not just a storage unit; it's an engineered system designed to solve the core logistical challenges of plastics manufacturing. By understanding the physics of heavy load management and the flow of a modern workshop, this system converts liabilities into assets.
Unlike conventional shelving, our drawer type mold rack features a 100% full-open drawer structure, supported by a robust three-pillar frame. When a drawer carrying a multi-ton mold is fully extended, the third "export" pillar provides a critical support point, preventing any tilting or stress on the main frame. This allows your overhead crane or chain hoist to achieve perfect vertical alignment with the mold's center of gravity. There are no crossbeams or shelf lips to navigate around, completely eliminating the risk of bumping and damaging the mold's delicate cavities or parting lines during lifting. Each drawer is also equipped with a mechanical self-locking safety pin, ensuring it remains securely in place during loading and unloading, meeting stringent OSHA safety standards.
The primary economic advantage of a professional mold racking system is its ability to utilize vertical space. By stacking molds weighing 2,000 to 6,000 lbs per layer, you can consolidate your entire tool inventory into a fraction of the original footprint. This frees up vast amounts of floor space, enabling you to add more injection or blow molding machines and directly increase production capacity. The system’s modular, add-on design means your storage can grow alongside your business. Critically, by integrating with an overhead crane, the required aisle width can be reduced from over 13 feet (for forklifts) to as little as 4 feet, maximizing storage density and optimizing workshop flow.
Each drawer glides on high-precision Harbin 6404 bearings, which convert sliding friction into rolling friction. This engineering detail means a single operator can pull out a 4,500-lb mold with minimal effort. For heavier applications, an optional pneumatic assist system automates the process with the push of a button, protecting your employees from strain. The entire structure undergoes a 7-step surface treatment, including acid washing, phosphating, and an 80μm powder coating. This creates a durable, corrosion-resistant barrier that protects not only the rack but also your valuable molds from the ambient humidity of the workshop, extending their operational life and safeguarding your investment.

Implementing an Erack die rack system marks a fundamental shift from reactive to proactive workshop management. Mold changeover times can be reduced by up to 80%, as finding and accessing the correct tool takes just minutes. Your workshop becomes a safer, cleaner, and more professional environment that reflects a high standard of 5S management. Molds are stored in designated, protected "apartments," instantly accessible and shielded from damage. This systematic approach not only boosts morale among your tool room technicians and die setters but also delivers a clear and rapid return on investment by maximizing machine uptime and preserving the life of your most critical production assets.
Yes. Each drawer is equipped with high-performance industrial bearings (typically Harbin 6403/6404) that reduce the required pull force to approximately 1% of the load's weight. This means a 4,000 Lb mold requires only about 40 Lbs of initial force to move. For molds exceeding this or for companies with strict ergonomic policies, our pneumatic-assisted models use factory compressed air to open and close the heaviest drawers with the push of a button.
The system is designed specifically for overhead crane integration. The 100% full-open drawer design moves the entire mold clear of the rack structure. This provides your crane hook with direct, top-down vertical access to the mold's lifting points without any obstructions, which is the safest and most efficient way to handle heavy tooling.
Clients typically report a space saving of 50% to 80%. This is achieved by converting horizontal floor space into organized vertical storage. Furthermore, by eliminating the need for wide forklift access aisles and adopting a narrow-aisle layout for crane access (as little as 4-5 feet), the storage density of your tool room or production area can be increased by as much as 300%.
We employ a 7-step industrial-grade surface treatment process. Before painting, every steel component undergoes shot blasting, acid washing, and phosphating. This creates a micro-etched surface that the powder coating can bond to chemically. We then apply a 60-80μm thick layer of high-quality epoxy resin powder and cure it. This creates a non-porous, highly durable finish that is significantly more resistant to chipping, scratching, and corrosion than standard liquid paint, ensuring a 15-year+ structural life even in demanding industrial environments.
Safety is paramount. The structure is built from heavy-duty Q235B structural steel (10# channel steel) with a safety factor of 1.2 or higher. Each rack must be securely anchored to the concrete floor with expansion bolts. Every drawer features an independent, physical safety pin that automatically locks it in the closed position to prevent accidental roll-out. Additionally, the three-pillar design ensures that even when a drawer is fully extended with a multi-ton load, the rack remains stable and the load is properly supported, preventing catastrophic failure.
