Mold Storage Engineering for New Zealand’s Seismic Microclimates & Heavy Industries
Storing precision injection molds, stamping dies, cold heading tools, and extrusion tooling presents mechanical challenges that standard warehouse pallet racking was never designed to address. Molds are ultra-dense, concentrated mass items often weighing between 800 kg and 6,000 kg within footprint areas smaller than a standard EUR or Chep pallet. When subjected to New Zealand’s stringent structural and seismic building regulations—notably AS/NZS 4084:2023 (Steel Storage Racking) and NZS 1170.5 (Structural Design Actions - Earthquake Actions)—die storage infrastructure demands rigorous static and dynamic structural modeling.
Key Engineering Differentiator: Unlike general pallet racks where loads are distributed over lengthy horizontal beams, mold storage racks experience severe point deflections and dynamic horizontal shock loads when slide-out shelves are extended. Our custom-manufactured tooling racks incorporate reinforced Q355B channel-steel guide tracks, dual-action safety drawer interlocks, and widened baseplate footprints engineered specifically to achieve building consents (including Council PS1/PS4 pathway support) across Auckland, Christchurch, Wellington, and the Waikato region.
1. Mitigating Dynamic Roll-Out Risk Under Seismic Strain
In New Zealand manufacturing facilities—ranging from high-volume packaging injection moulders in Mount Wellington and East Tamaki (Auckland) to precision engineering toolrooms in Hornby (Christchurch)—the primary safety hazard of mold racks is the unintended release of slide-out drawers during an earthquake. Under NZS 1170.5 seismic loading, spectral accelerations can disengage elementary friction latches.
Our heavy-duty roll-out mold racks feature positive-engagement mechanical drawer safety pins and an automated mechanical interlocking mechanism that permits only one drawer per bay to be pulled out at any given moment. This prevents the center of gravity (CoG) from shifting outward past the tipping tipping line, safeguarding your operators and valuable tool steel assets from cataclysmic frame overturn.
2. Substrate Anchor Load Distribution & Slab Structural Integrity
The standard concrete floor slab in New Zealand industrial units typically ranges from 150 mm to 200 mm thickness with concrete compressive strength between 25 MPa and 35 MPa. Concentrating multi-ton progressive stamping dies on four narrow upright posts can easily punch through or induce shear-cone failures in the slab under seismic cyclic uplifts.
We solve this challenge by supplying laser-profiled, extra-heavy baseplates (12mm to 20mm thickness) engineered to accommodate chemical capsule anchoring (e.g., M16 or M20 cracked-concrete approved anchors). Our finite element analysis (FEA) models evaluate anchor pull-out capacity and edge-distance criteria, ensuring seamless compliance with the New Zealand Building Code (Clause B1 Structure) and WorkSafe NZ Guidelines for the Safe Operation of Heavy Storage Structures.
Targeted Applications
Tailored Tooling Logistics Across New Zealand Sectors
Explore how our specialized mold rack designs resolve workflow bottlenecks, overhead crane dependencies, and footprint constraints in key industrial applications.
Plastic Injection Moulding Facilities
High-speed packaging, dairy export caps, medical plastics, and agricultural irrigation moulders in Auckland and the Waikato require quick tool changes (SMED). Slide-out mold racks with integrated top overhead hoists eliminate forklift congestion in tight press aisles, allowing single-operator tool retrieval within 180 seconds.

Zero Hydraulic Oil Pooling
Metal Stamping & Automotive Components
Heavy progressive dies, punch press tooling, and coil blanking dies demand massive weight tolerance. With drawer capacities up to 5,000 kg per level, our heavy-gauge cold-formed uprights and structural channel beams accommodate intense shock loading without residual frame deformation.

Drop-Bed Anti-Deflection Design
Aluminium Extrusion & Die Casting
High-temperature dies and extrusion rings require organized, dry, and damage-protected shelving. Utilizing heavy-duty galvanized structural grids or thick steel plates, our racks protect critical polished die faces from corrosive moisture and accidental contact with forklift tines.
