Materials and Production Process of Heavy-duty Pallet Moulds

Materials Used in Heavy-Duty Pallet Moulds

Heavy-duty pallet moulds must withstand high pressure, abrasion, and repeated use, so they are typically made from high-quality tool steels with special treatments:

1. Core Mould Materials

P20 Steel – A common pre-hardened steel (HRC 28-32) for medium-duty moulds.

718H Steel (Modified P20) – Higher hardness (HRC 32-36) and better polishability for long production runs.

H13 Steel (Hot Work Tool Steel) – Excellent heat resistance (HRC 48-52), used for high-volume production.

S136 / Stainless Steel – For corrosion-resistant moulds (e.g., food-grade pallets).

2. Surface Treatments (Enhancing Durability)

Nitriding – Increases surface hardness and wear resistance.

Hard Chrome Plating – Reduces friction and prevents corrosion.

Titanium Nitride (TiN) Coating – Extends mould life in abrasive conditions.

Production Process of Heavy-Duty Pallet Moulds

1. Design & Engineering

3D CAD Modeling – Ensures precise dimensions for pallet strength and functionality.

CAE Analysis – Simulates injection flow, cooling, and stress distribution.

2. CNC Machining

Rough Machining – Milling the basic shape from steel blocks.

Precision CNC Machining – High-accuracy cutting of cavities, cores, and ejector systems.

EDM (Electrical Discharge Machining) – For intricate details and sharp edges.

3. Heat Treatment & Hardening

Quenching & Tempering – Enhances steel hardness (e.g., H13 steel up to HRC 50).

Stress Relieving – Prevents warping during long-term use.

4. Surface Finishing & Polishing

Manual/CNC Polishing – Ensures smooth pallet surfaces (prevents sticking).

Texture Application – Adds anti-slip patterns if required.

5. Assembly & Testing

Mould Assembly – Fitting ejector pins, sliders, and cooling channels.

Trial Injection – Tests mould performance and pallet quality.

Key Design Considerations

A. Load-Bearing Structure

Thick ribs & reinforced legs for high static/dynamic loads.

Optimized wall thickness (typically 3–5mm) to balance strength & weight.

B. Draft Angles & Part Release

1–3° draft angles on vertical walls for easy ejection.

Smooth transitions to avoid stress concentrations.

C. Anti-Warping Design

Balanced cooling channels to prevent uneven shrinkage.

Symmetrical rib patterns for uniform strength.

D. Customization Options

Nestable/stackable designs for space-saving storage.

Forklift entry points (4-way or 2-way access).

Drainage holes (for outdoor/cleanroom use).

Advantages of Adding Reinforced Steel to Heavy-Duty Pallets

1. Increased Load Capacity

Supports 5,000–20,000+ kg static loads (vs. 1,000–5,000 kg for all-plastic pallets).

Prevents bending/flexing under extreme weights (e.g., machinery, bulk liquids).

2. Enhanced Durability & Longevity

Steel resists wear from forklifts, pallet jacks, and rough handling.

Reduces cracking/splitting in high-stress areas (e.g., leg supports).

3. Improved Stability & Safety

Minimizes deflection during dynamic loads (e.g., conveyor systems).

Prevents sudden failure under heavy weights, improving workplace safety.

4. Better Racking & Stacking Performance

Steel-reinforced pallets maintain shape in racking systems (e.g., warehouse shelving).

Prevents sagging when stacked under heavy loads.

5. Fire & Chemical Resistance

Steel adds fire retardancy compared to all-plastic designs.

Resists oil, solvents, and corrosive chemicals better than plastic alone.

6. Cost-Effectiveness Over Time

Longer lifespan reduces replacement frequency.

Lower maintenance (no splinters, cracks, or warping).
