Are your high-value injection and blow molds crowding the production floor next to your molding machines? This disorganization not only wastes valuable space but also directly delays changeovers, increases the risk of costly damage to precision mold surfaces, and creates safety hazards for your team. It's time to reclaim your workshop floor and accelerate your production cycle. |
In a high-throughput plastics manufacturing facility—whether you're producing PET bottles, thermoformed cups, or large jerry cans—every square foot of floor space is prime real estate. Yet, a common bottleneck persists: the inefficient and hazardous storage of heavy, expensive molds. Lying on wooden pallets, these critical assets are susceptible to damage, corrosion, and create a logistical nightmare for your Die Setters and Production Supervisors.
This disorganized approach directly impacts your bottom line. Every minute your team spends searching for the right mold, clearing a path for a forklift, and carefully maneuvering a multi-ton die into the injection molding machine is a minute of lost production. The risk of colliding with a precision mold face during transit is a constant threat to your asset's longevity.
The traditional, inefficient method: valuable molds left exposed on the floor, wasting space and risking damage.
The solution is not just about tidying up; it's a strategic overhaul of your workflow. A purpose-built heavy duty mold rack transforms dead vertical space into a high-density, easily accessible storage hub. The core innovation lies in the 100% full-open drawer design. When a drawer is extended, the entire mold is clear of the rack's frame, providing unobstructed, zero-dead-angle vertical access for your existing overhead crane or chain hoist.
This completely eliminates the need for wide forklift aisles next to your mold storage area. Your Mold Changer can now position the hoist directly over the required mold, lift it cleanly, and transfer it to the production machine. This single change can reduce the required aisle width from over 12 feet to as little as 4 feet, freeing up significant floor space for additional production lines or material staging.
The Erack solution: A full-open drawer allows an overhead crane to access a heavy injection mold with zero obstruction, streamlining the changeover process.
Your multi-cavity blow mold rack needs to handle immense weight without compromise. Our systems are not standard shelving; they are engineered structures. The frame is constructed from 10# channel steel (Q235B), providing a robust backbone. This three-pillar architecture ensures that even when a drawer carrying a 3-ton (6,600 lbs) mold is fully extended, the structure remains stable without any plastic deformation. The back of the die rack is reinforced with solid steel cross-bracing, providing exceptional resistance to lateral forces and ensuring the entire system is rigid and secure, even under full load.
Safety and ergonomics are paramount. Pulling out a 4,000-lb mold should not be a test of strength. Each drawer glides on high-precision Harbin 6404 bearings, converting sliding friction into smooth, rolling motion. This reduces the required pull-force to a fraction of the mold's weight, enabling a single operator to access heavy tooling. For an even higher standard of EHS, a pneumatic-assist system can be integrated, allowing push-button operation for the heaviest molds.
To guarantee operator safety and comply with OSHA standards, every drawer is fitted with a robust, self-locking mechanical safety pin. Once a drawer is pushed in, the pin automatically engages, preventing any possibility of it sliding out due to vibration. During retrieval, the operator must consciously disengage the pin, creating a deliberate and safe workflow.

A single high-precision injection mold can be a six-figure investment. Protecting it from corrosion is not optional. Our mold storage racks undergo a rigorous 7-step surface treatment process, including acid washing, phosphating, and a 60-80μm thick powder-coating application. This creates an industrial-grade finish that resists rust, chipping, and chemical exposure, ensuring your molds are stored in a clean, dry, and stable environment for over 15 years.
Furthermore, the modular main-and-add-on design of the die storage rack system means it can grow with your business. As you add more thermoforming machines or expand your product lines, new rack sections can be seamlessly connected, ensuring your storage infrastructure scales with your production capacity.
Large-scale deployment showcases the system's modularity, creating a high-density, organized central mold library.
Investing in a professional drawer type mold rack is not an expense; it's a direct investment in operational efficiency and asset protection. The benefits are immediate and quantifiable:
Stop letting inefficient storage dictate the pace of your production. It's time to implement a system that matches the precision and value of the molds it protects.
Our standard units are engineered to hold between 2,200 lbs and 6,600 lbs (1 to 3 metric tons) per drawer level. The capacity is determined by the steel thickness and structural design. We can also provide custom-engineered solutions for exceptionally heavy or oversized molds used in large-part molding.
The system is designed specifically for crane integration. The 100% full-extension drawers ensure that when a drawer is pulled out, the mold's center of gravity is completely clear of the rack structure above. This allows your crane hook to descend directly for a safe, vertical lift without any need for angled or risky pulls.
No. The racks are protected by a comprehensive 7-step surface treatment that includes shot blasting, acid pickling, and phosphating before the final electrostatic powder coating is applied. This multi-layer protection is designed to withstand corrosive industrial environments and is warranted against rust for up to 15 years.
Absolutely. The system is based on a modular design featuring "starter" and "add-on" units. This allows you to start with the capacity you need today and easily expand the row by adding new sections as your mold library grows, ensuring a scalable, long-term solution.
No, it is designed for single-operator use. Each drawer is equipped with precision roller bearings that significantly reduce the initial force required to move the load. For molds exceeding 4,400 lbs (2 tons), we highly recommend the optional pneumatic assist system, which makes opening and closing the drawer as simple as pressing a button.
