Your workshop floor is not a warehouse. Yet, multi-ton injection and blow molds are scattered on pallets, blocking access to machines and creating daily safety hazards. Changeovers take hours, not minutes, as technicians hunt for tools and wrestle with forklifts. This isn't just inefficient; it's a direct drain on your production uptime and a constant risk to your most expensive assets. |
In the fast-paced world of plastics manufacturing—from PET bottle production to custom thermoformed containers—the single greatest bottleneck is often the time between production runs: the mold changeover. A chaotic tool room or a cluttered staging area around your injection molding machines directly translates into lost revenue. The traditional method of storing heavy, high-value plastic injection mold storage rack systems on the floor or on static shelving is a system designed for failure.
Before implementing a dedicated solution, a typical plastics workshop faces a daily struggle that goes far beyond simple untidiness:
A purpose-built heavy duty mold rack isn't just a piece of steel; it's a productivity machine. By understanding the physics of load-bearing and the workflow of a mold setter, we can transform your entire changeover process. The system is built on a foundation of uncompromised engineering principles.
The backbone of our die rack is constructed from Q235B structural steel, specifically using 10# channel steel (100mm x 48mm) for the main uprights. This isn't arbitrary. This material and profile provide an exceptional moment of inertia, resisting the bending and torsional forces exerted by loads up to 3 tons (6,600 lbs) per layer. A robust frame means zero plastic deformation, ensuring the drawers slide smoothly without binding, even after years of heavy use. This structural integrity allows you to safely go vertical, transforming a 1,000 sq. ft. storage footprint into a highly organized 300 sq. ft. tower of productivity.
The core innovation is the die roll out racks design. Each drawer, riding on high-precision 6404 series bearings from HRB, can be fully extended from the rack. This seemingly simple feature is a game-changer:
A plastic mold's value lies in its flawless surface. Our 7-step surface treatment process is designed to create an inert, protective micro-environment. The steel is first shot-blasted, then acid-washed and phosphated before receiving a 60-80μm thick layer of high-quality epoxy powder coated rack finish. This industrial-grade coating creates a barrier that is highly resistant to cutting oils, hydraulic fluids, and atmospheric humidity, preventing the onset of rust that could compromise your final product quality.
Safety is not an option. Every drawer is equipped with a robust, spring-loaded mechanical safety pin. This physical lock automatically engages when the drawer is closed, preventing any chance of it drifting open due to vibration. When extended, a secondary lock prevents it from being pushed in or pulled out further until the operator intentionally disengages it. This multi-layered system ensures full compliance with stringent safety standards like OSHA and ANSI.
Integrating a systematic mold racking system delivers quantifiable returns. What was once a chaotic "before" state becomes an organized and efficient "after":
| Metric | Before: Traditional Storage | After: Erack Mold Rack System |
| Mold Changeover Time | 45 - 90 minutes (includes finding, clearing, and transport) | 5 - 10 minutes (direct access and vertical lift) |
| Floor Space Utilization | Low. Large footprint with wide forklift aisles required. | High. Vertical storage frees up to 80% of floor space. |
| Asset Protection | High risk of collision, scratches, and corrosion. | Dedicated, protected slots prevent damage and rust. |
| Worker Safety | High risk of strain, trip, and crush injuries. | Ergonomic, low-force operation with mechanical safeguards. |
By transforming your injection mold storage from a logistical problem into a strategic advantage, you enable faster response to customer orders, increase the productive capacity of your existing machinery, and create a safer, more professional environment for your team.
Our standard models are engineered to handle loads from 1,000 kg (2,200 lbs) to 3,000 kg (6,600 lbs) per drawer. For unusually large or heavy molds, such as those used in automotive bumper manufacturing or large container blow molding, we can engineer custom solutions with even higher load capacities.
It directly attacks the two biggest time-wasters: searching and transportation. With a designated slot for every mold, the "search" time is eliminated. The 100% pull-out drawer combined with an overhead crane removes the need for slow, careful forklift navigation, reducing the "transport" time from 15-30 minutes to less than 2 minutes.
Absolutely. The shelf height of our mold racks is fully adjustable, typically on a 50mm or 75mm pitch. This allows you to configure each bay to the specific heights of your molds, creating a high-density system that accommodates your entire tooling inventory, preventing wasted vertical space.
Yes. The epoxy powder coating is baked on, creating a hard, non-porous finish that is highly resistant to the oils, greases, and mild solvents commonly found in a plastic molding environment. This makes cleaning easy and prevents chemicals from reaching and corroding the underlying steel.
Each drawer is equipped with a primary self-locking mechanism. When the drawer is pushed in, a heavy-duty physical safety pin automatically drops into a locked position. It cannot slide out due to factory floor vibrations or accidental bumps. It can only be opened when an operator intentionally disengages this pin to pull the drawer out.
