Your workshop floor is cluttered with expensive injection and blow molds. Machine downtime during changeovers is killing your output. Valuable floor space that could house another molding machine is wasted on chaotic, ground-level storage. There is a structured, safer, and far more efficient way to manage these critical assets. |
In the high-volume world of plastic packaging—from PET bottles to thermoformed containers—the efficiency of your injection molding or blow molding machines dictates profitability. However, the focus on machine uptime often overlooks a critical bottleneck: the disorganized, inefficient, and hazardous state of mold storage. When multi-ton, high-value injection molds or blow molds are left on wooden pallets or stacked haphazardly on the floor, the hidden costs begin to accumulate rapidly.
This "traditional" method creates a cascade of operational problems:
Traditional storage: Molds on pallets create safety hazards and waste valuable floor space.
A purpose-built heavy duty mold racking system is not just a piece of shelving; it's an integrated part of an efficient production workflow. The design directly addresses the core challenges of a plastics manufacturing environment through superior engineering.
The foundation of our system is its robust frame, constructed from Q235B structural steel, often utilizing 10# channel steel for the main pillars. This isn't just about strength; it's about stability under dynamic loads. This high-rigidity structure ensures zero frame deformation, even when a single drawer is loaded with a 3,000kg (6,600 Lbs) mold. This allows you to safely utilize vertical space, transforming a sprawling mold graveyard into a condensed, organized, high-density storage hub and freeing up to 80% of your floor space.
The 10# channel steel uprights and cross-bracing provide unwavering stability for multi-ton loads.
The core innovation is the roll-out drawer system. Each drawer, supported by high-precision Harbin bearings, extends 100% out of the rack. This engineering feature is critical. It allows your overhead crane or chain hoist to achieve a direct, vertical lift from the mold's center of gravity. This completely eliminates the risk of bumping the mold against the rack frame during extraction—a common cause of damage to cooling lines and polished surfaces. The result is a seamless, single-operator process that is both fast and safe.
A fully extended drawer presents the mold for a perfect vertical lift, eliminating collision risks.
Safety is non-negotiable. Each drawer is equipped with a mechanical self-locking safety pin. This physical lock prevents any possibility of the drawer sliding out accidentally. When the drawer is fully extended, another locking mechanism engages, preventing it from tipping. These redundant safety features are not optional extras; they are fundamental to creating a secure work environment that protects your team and complies with stringent industrial safety standards.

Implementing a dedicated drawer type mold rack is a strategic move that pays immediate dividends. The "After" scenario is a stark contrast to the previous state of disorganization.
By moving from floor storage to a vertical die rack system, you achieve measurable improvements:
The result: A clean, high-density, and highly efficient mold storage area supporting lean manufacturing principles.
Our standard heavy-duty mould storage racks are engineered with a single-drawer load capacity ranging from 1,000 kg to 3,000 kg (approx. 2,200 to 6,600 Lbs). The capacity is determined by the steel thickness and structural design. We always conduct a detailed analysis of your heaviest molds to ensure the provided solution exceeds your safety requirements.
Absolutely. The system is modular. The height between layers is fully adjustable, typically in 2-inch increments. This allows you to create customized compartments to efficiently store molds of various sizes in the same rack unit, maximizing storage density and preventing wasted space.
The system is designed to work seamlessly with standard factory cranes. The 100% full-open drawer design ensures that once a drawer is extended, the crane hook has unimpeded vertical access to the mold. For areas without existing crane coverage, we can also integrate a dedicated hoist and rail system directly onto the top of the rack structure.
We employ a rigorous 7-step industrial-grade surface treatment process. This includes shot blasting to create an ideal surface profile, followed by acid washing, phosphating, and finally an electrostatic powder coating with a thickness of 60-80μm. This creates a durable, corrosion-resistant finish that is far superior to standard paint and designed to withstand demanding industrial environments.
The rack is a cornerstone of SMED implementation. It drastically cuts down on the "search and transport" portion of the die change process. By providing a designated, instantly accessible location for every mold right next to the production line, it eliminates wasted time. When combined with an overhead crane, the entire process of retrieving the old mold and loading the new one can be reduced from over 30 minutes to under 5, significantly increasing machine uptime and overall equipment effectiveness (OEE).
