Industrial Engineering & Heavy-Duty Storage Solutions Engineered for High-Capacity Injection Mold Safekeeping
Explore our engineering-grade drawer racks, high-capacity tool shelves, and warehouse organization systems.
A trusted global leader in structural engineering, heavy-duty warehouse storage, and high-performance mold racking systems.
Established in 2016, Guangdong Shibang Storage Rack Co., Ltd. is a premier manufacturing enterprise specializing in the design, engineering, and global distribution of heavy-duty industrial storage racks and precision drawer racking systems. Operating from our state-of-the-art 35,000㎡ modern manufacturing complex in China, we deliver high-capacity industrial shelving systems for manufacturing facilities, logistics hubs, automotive assembly centers, and tooling rooms worldwide.
Over the years, Shibang has generated an annual export revenue of approximately USD 18 million. Backed by 8 years of dedicated export experience and 15 years of industry experience in structural steel fabrication, our engineering division develops robust solutions tailored to international warehouse safety and structural guidelines. We provide vertically integrated services—spanning raw material inspection, finite element analysis (FEA), high-precision welding, automated electrostatic powder coating, and load test validation.
Optimizing vertical space and operator safety through advanced mechanical design and finite structural calculations.
Manufactured using high-tensile hot and cold-rolled steel (Q235B and Q355B grades) conforming to GB/T 1591. The upright frames feature a multi-bend profile to optimize load distribution and seismic resilience.
Our sliding drawers employ heavy-duty industrial ball-bearing runners or roller track assemblies, enabling smooth extraction of molds weighing up to 2,000 kg per level with minimal physical effort.
Integrated mechanical safety locks ensure that only one drawer can be extended at any given time. This feature distributes the center of gravity and prevents structure overturning during heavy mold maneuvers.
| Racking Spec Type | Load Capacity (per level) | Drawer Extension Ratio | Structural Material Choice | Common Industrial Application |
|---|---|---|---|---|
| Light Drawer Rack | 200 – 500 kg | 60% – 70% Slide-out | Cold-Rolled Steel Q235B | Precision electronics, tooling components, light plastic injection molds |
| Standard Heavy-Duty | 800 – 1,200 kg | 70% – 80% Slide-out | Enhanced Structural Steel Q235B | Automotive plastic molding, household appliance manufacturing |
| Ultra Heavy-Duty | 1,500 – 3,000 kg+ | 100% Full Extension | High-Strength Q355B Steel | Heavy casting molds, forging dies, structural components, aerospace tooling |
| Semi-Open Storage | 1,000 – 1,500 kg | 50% Slide-out | Q235B Steel Profiles | Industrial maintenance bays, heavy hardware warehouses |
Note on Engineering Deflection Ratios: Every Shibang heavy-duty mold racking system is designed in compliance with the L/250 (up to L/300 for sensitive instrumentation tooling) deflection limit under static load conditions, guaranteeing long-term dimensional stability and operator safety.
How we engineer tailored physical asset storage structures to integrate with highly specialized manufacturing processes.
High-cycle production lines require instant access to heavy metal bumper or dashboard molds. Our racking accommodates overhead crane hoists to enable rapid mold changes, minimizing downtime and optimizing Lean manufacturing flows.
For high-precision aerospace carbon composite tooling, we provide clean-finish, epoxy-coated drawer structures that protect delicate mold edges from metal-on-metal abrasion, preventing micro-scratches and component contamination.
Compact, ESD-safe modular tool racks designed for cleanroom operations. Perfect for high-density storage of micro-molds, tooling inserts, and precise punch dies utilized in high-volume smartphone and component packaging.
A look inside our 35,000㎡ advanced manufacturing facility, where industrial automation and quality control converge.
Integrating digital connectivity and smart automation into industrial storage infrastructure.
Developing structural shelves integrated with weight-sensing load cells and RFID chips. This permits real-time inventory visibility and localized load balancing notifications to prevent structural stress overloads.
We are engineering next-generation structural rack clearances to natively support automated guided vehicles (AGVs) and automated storage/retrieval systems (ASRS), reducing manual heavy machinery manipulation requirements.
Our spray painting lines are transitioning to zero-VOC, ultra-durable thermosetting powder coatings. These provide superior resistance to high-humidity, marine environments, and chemical exposures without environmental degradation.
Ensuring compliance with localized safety standards, engineering codes, and strict installation processes.
Exporting to highly regulated environments like North America and the European Union requires compliance with rigid codes. Shibang designs products in alignment with the following standards:
Our quality control system comprises ISO 9001 procedures, incoming raw material verification, processing stage inspection, and finished product testing. Each system is evaluated through weld inspection, layer thickness testing, loading capability test, and structural sizing checks.
For large-scale industrial storage installations, local ground conditions and seismic categorization are critical variables. Shibang delivers complete configuration designs containing detailed site preparation requirements:
A guide for sourcing directors to evaluate raw materials, select suppliers, and specify requirements in RFPs.
Begin by calculating the maximum dry weight of the heaviest molds. Standardizing drawer levels to either 1,000kg, 1,500kg or 2,000kg guarantees long-term performance stability without material failure.
Opt for standard slide configurations (70% extraction) if forklift and overhead hoists have easy, direct access. Choose 100% full-extension systems for compact floor layouts where overhead cranes handle vertical mold extraction.
Select electrostatic powder coatings with at least 60-80 microns thickness for standard tooling rooms. For high-humidity environments, look for pre-galvanized structures to prevent oxidization under challenging conditions.
Expert insights regarding industrial mold racking design, selection, installation, and maintenance.
Generally, standard heavy-duty drawer racking systems are engineered for load capacities ranging between 500 kg to 2,000 kg per shelf level. At Guangdong Shibang, we specialize in high-capacity manufacturing, tailoring structures to hold up to 3,000 kg and above per drawer panel using high-strength Q355B cold-rolled steel and reinforced roller tracks.
The safety interlocking mechanism restricts the operation of drawers so that only one drawer can be pulled out at a single moment. Extending multiple drawers containing heavy tooling shifts the rack's center of gravity forward, creating a tipping risk. The automatic interlocking system prevents this, maintaining structural stability and ensuring operator safety.
Yes. Standard drawer configurations are designed to interface seamlessly with monorail cranes or overhead bridge cranes. The drawer slides open to expose the mold completely from the top, allowing the crane hoist hook to latch onto the mold's lifting eye bolt directly, without requiring forklift intervention.
All structural elements undergo a multi-stage pretreatment process (degreasing, phosphating, acid pickling) followed by an automated electrostatic thermosetting epoxy powder coating. The resulting finish resists moisture, grease, industrial solvents, and physical scratches, preventing rust and keeping molds free of metal debris.
Our engineering department utilizes ANSYS Finite Element Analysis (FEA) software to model and calculate structural stresses prior to manufacturing. In production, we run destructive and non-destructive load tests on random samples. This includes overloading drawers up to 1.5 times their rated capacity to verify safety margins.
