Mold Rack — Heavy-Duty Drawer Storage for Injection & Stamping Dies
Purpose-built for plastic injection molds, die-casting molds, stamping dies and tooling. Roll-out drawer design pulls 1–8 ton molds fully clear of the rack for crane lifting — zero need to dismantle adjacent units. AME Rack manufactures EN 15512 / RMI MH16 compliant systems exported to 65+ countries.
Mold Rack — Roll-Out Drawer Storage Engineered for Heavy Tooling
Mold racks (also called mould racks, die storage racks or pull-out drawer racks) replace traditional pallet shelves with reinforced cantilever drawers that extend 100% out of the rack on industrial-grade rollers or telescopic rails. The mold is craned in or out at any level without disturbing adjacent drawers, eliminating the danger of stacked-mold collapse.
Standard in plastic injection molding plants, automotive stamping shops, die-casting foundries, rubber molding factories, and toolrooms — anywhere expensive precision tools (typically USD 5,000–500,000 each) need safe, fast, organised access.
Why Mold Racks Pay Back Within One Production Cycle
Eight engineering and operational advantages that explain why mold drawer racking is the standard storage system for injection molders, stamping shops and die-casting foundries worldwide.
Heavy Drawer Load
Single drawer rated 1,000–8,000 kg. Roller-bearing or telescopic rail system tested to 1.5× working load per EN 15512.
100% Pull-Out
Drawer extends fully clear of rack — overhead crane, jib crane or chain hoist lifts mold without dismantling rack frame.
Safety Lock
Drop-in safety pin locks drawer closed during forklift travel; spring lock prevents accidental drawer roll-out during seismic events.
Fast Tool Change
Cut average mold-change downtime by 40–60% vs floor stacking — operator locates and extracts mold in under 90 seconds.
No Stacking Damage
Each mold sits on its own drawer — eliminates the scratch, dent and corner-chip risk of traditional ground-stacking on wood pallets.
Modular Layout
Drawer pitch adjustable at 100 mm increments — mix 2 T and 5 T drawers in the same upright frame to match mold size variety.
Indoor or Tool Yard
Standard powder coat for indoor toolrooms; HDG 80–120 μm for outdoor / unheated tool yard storage.
ERP-Ready Labelling
Optional bar-code label holder + RFID slot on every drawer face — integrates with MES / ERP for real-time mold inventory tracking.
Three Mold Storage Configurations for Every Tooling Operation
From standard drawer-type mold racks to heavy-duty full-open systems and selective pallet racking adapted for mold storage — match drawer load, access method and footprint to your specific tooling profile.
Standard Mold Rack
1–2 T per drawer, telescopic rails, 3–5 level upright. The volume seller — fits 80% of plastic injection and small stamping operations with full drawer pull-out for crane lifting.
Heavy-Duty Full-Open Mold Rack
2–5 T per drawer, 100% full pull-out structural rails, reinforced upright. Engineered for large injection molds (>1,000 t machine) and automotive stamping dies requiring complete crane access from above.
Selective Rack for Mold Storage
Standard selective pallet racking adapted for mold storage — molds rest on reinforced pallets or steel cradles. Forklift-access, lowest cost-per-position, ideal for low-rotation mold archives and overflow inventory.

Heavy Forging Die
Hot forging dies for crankshafts, gears, large industrial parts — 8 T+.
How to Specify a Mold Rack Layout in 3 Decisions
Drawer capacity, crane access and aisle pull-out clearance drive 85% of total mold storage project cost. Get these three right before sizing uprights.
Drawer Capacity — Size for Heaviest Mold
Survey your mold inventory by weight band. Always spec drawer capacity for your heaviest 90th percentile mold, not the average — under-spec drawers fail catastrophically.
- ≤ 1,000 kg molds — 1 T drawer rack, 5 levels
- 1,000–3,000 kg — 3 T standard, 3–4 levels
- 3,000–5,000 kg — 5 T heavy-duty, 2–3 levels
- 5,000–8,000 kg — 8 T extra-heavy, 1–2 levels
Crane Access — Hook Height Above Top Drawer
Overhead crane hook must clear top drawer at full extension + sling height. Otherwise top drawer becomes inaccessible.
- Min hook clearance — top drawer + 1.5 m sling
- Jib crane radius ≥ drawer pull-out + 1 m
- For tall buildings, prefer 2 lower drawers vs 3 tall
- Chain hoist OK for ≤ 3 T drawers only
Aisle Width — Pull-Out + Walk Clearance
Aisle must accommodate fully-extended drawer PLUS clearance for crane hook approach and operator safety zone.
- Min aisle = drawer depth × 1.05 + 1.5 m walk
- 1.2 m drawer → 2.8 m aisle minimum
- 1.5 m drawer → 3.1 m aisle minimum
- Double-sided rack → each side needs full aisle
| Mold Weight Band | Drawer Capacity | Drawer Size | Levels per Upright | Typical Industry |
|---|---|---|---|---|
| 200 – 600 kg | 1 T light-duty | 1000 × 800 mm | 5 levels | Small injection, electronics |
| 600 – 1,800 kg | 2 T standard | 1200 × 1000 mm | 4 levels | Consumer plastics |
| 1,800 – 3,000 kg | 3 T standard | 1200 × 1000 mm | 3 levels | Auto interior, packaging |
| 3,000 – 5,000 kg | 5 T heavy-duty | 1500 × 1200 mm | 2 – 3 levels | Die casting, auto stamping |
| 5,000 – 8,000 kg | 8 T extra-heavy | 1800 × 1400 mm | 1 – 2 levels | BIW stamping, forging die |
Mold Rack vs Floor Stacking / Pallet Rack / Cantilever / Vertical Lift — Honest Pros & Cons
Which mold storage system is right for your toolroom? Compare on tool-change speed, damage risk, density, capex, crane requirement and ERP integration.
| Factor | Mold Drawer Rack | Floor Stacking | Pallet Rack | Cantilever Rack | Vertical Lift Module |
|---|---|---|---|---|---|
| Tool-Change Speed | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| Damage Risk to Mold | ★★★★★ Low | ★★★★★ Very high | ★★★★★ | ★★★★★ | ★★★★★ |
| Storage Density | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| Crane Required | Yes (jib / overhead) | Yes | Forklift only | Forklift only | Built-in extractor |
| Capex (per mold) | $$ Mid | $ Zero | $$ Low | $$ Low | $$$$$ Very high |
| Heavy Mold Capability | Up to 8 T | Unlimited | 1.5 T per beam | 2.5 T per arm | Up to 1 T typical |
| ERP / RFID Ready | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ | ★★★★★ |
| Best For | 50–500 molds, 1–8 T | Few molds, low value | Light molds <1 T | Long dies > 2 m | 200+ small precision tools |
50+ molds, 1–8 T each, crane access
Standard solution for plastic injection, automotive stamping, die-casting. ROI from reduced tool-change downtime payback typically 12–18 months.
Hidden cost of mold damage
"Free" floor stacking causes USD 2,000–20,000/yr in mold corner-chip, paint scratch and rust damage — typically exceeds mold rack capex in year 2.
Many small, <1 T precision tools
Stencils, gauges, small dies, electronics fixtures. 90% density gain but 5–8× capex of mold rack. Only economical above 200 SKUs.
Toolrooms with mixed mold profiles
Mold rack for compact heavy dies; cantilever for long structural beams and skid-frame jigs. One unified rack catalogue from AME Rack.
Real Mold Rack Installations Around the World
Three recent projects across three continents — covering our three core configurations: standard mold rack, full-open mold rack, and beam-type pallet rack adapted for mold storage. Each shows the system type, tool inventory served, lead time and verified ROI metric.
Querétaro Plastic Injection — Standard Mold Rack
Consumer goods injection molder with 220 active molds ranging 400–2,800 kg. We delivered mixed 2 T + 3 T standard mold racks across 14 upright frames. Bar-code label slots on every drawer feed plant SAP MES — mold location lookup time dropped from 4 minutes to 8 seconds.
Stuttgart Automotive Stamping — Full-Open Mold Rack
Tier-1 automotive supplier replaced floor-stacking of body-in-white stamping dies (1–3 T each) with full-open mold rack system — 100% drawer extension gives crane direct top-access on every die. Twin-pin seismic lock standard, RFID label slot on every drawer for MES integration. Tool-change downtime reduced from 45 minutes to 12 minutes per die change.
Bursa Die-Casting Foundry — Beam-Type Pallet Rack
Aluminium die-casting foundry needed cost-effective storage for 180 low-rotation backup molds (1.5–4 T) alongside their active toolroom. We delivered beam-type selective pallet racking with custom steel cradles bolted to the pallet positions — forklift-access from the aisle, lowest cost-per-position, and crane-compatible for the heavier loads.
