1. Overview of Plastic Pallets
Plastic pallets are widely used in logistics, warehousing, and manufacturing. Compared to wooden pallets, they are corrosion-resistant, lightweight, easy to clean, and long-lasting, making them ideal for food, pharmaceutical, chemical, and electronics industries.
Producing plastic pallets requires large-tonnage, high-injection-capacity, and stable clamping force to handle big, thick-walled products.
2. Types of Injection Molding Machines for Pallets
1. Two-Platen Injection Molding Machine
· Features:
o Uses a two-platen clamping system, saving space compared to traditional three-platen machines.
o Clamping force: Typically 1000–6000 tons, suitable for large pallets (e.g., standard 1200×1000mm size).
o Energy-efficient: 15–30% lower energy consumption than three-platen machines.
· Applications:
o Medium/large pallets (e.g., EPAL pallets, heavy-duty designs).
o Thick-walled, high-load pallets (dynamic load capacity: 1.5–3 tons).
2. All-Electric Injection Molding Machine
· Features:
o High precision, low energy use: Servo motors reduce energy consumption by 40–60%.
o Clean production: No hydraulic oil, ideal for food/pharmaceutical-grade pallets.
o Clamping force: 500–2500 tons, best for small/medium precision pallets.
· Applications:
o Lightweight, high-accuracy pallets (e.g., medical cold-chain pallets, anti-static pallets).
o Small-batch, multi-variety production.
3. Hybrid Injection Molding Machine
· Features:
o Combines hydraulic clamping + electric injection for a balance of power and efficiency.
o Clamping force: 1500–4000 tons, good for mid-sized pallets.
· Applications:
o Cost-effective pallet production (e.g., logistics pallets).
o Manufacturers needing a balance between energy savings and cost.
4. Multi-Material Injection Molding Machine
· Features:
o Can inject two or more materials (e.g., PP + TPE) for advanced functionality.
o Used for anti-slip pads, embedded RFID tags, etc.
· Applications:
o Specialty pallets (e.g., anti-slip, UV-resistant, low-temperature pallets).
o High-value custom production.
5. Market Trends for Plastic Pallets
1. Growing Demand
· Logistics expansion: E-commerce and cold-chain logistics drive demand; global plastic pallet market grows 5–7% annually (2023–2030).
· Eco-friendly policies: Wooden pallets are being phased out in favor of recyclable PP/HDPE pallets.
2. Technology Trends
· Lightweight designs: Optimized structures (e.g., grid reinforcements) reduce weight.
· Smart manufacturing:
o IoT-enabled machines: Real-time monitoring for better quality.
o Automation: Robots for part removal and stacking.
· Green production:
o Bio-based plastics (e.g., PLA).
o Recycled pallet reprocessing.
6. How to Choose the Right Machine?
1. Match Clamping Force to Pallet Size
Pallet Type | Clamping Force (tons) | Injection Volume (g) |
Small (800×600mm) | 800–1500 | 2000–4000 |
Standard (1200×1000mm) | 1800–3500 | 5000–10000 |
Heavy-duty (3+ tons) | 3500–6000 | 10000–20000 |
Note: Clamping force formula:
Clamping Force (tons)=Projected Area (cm2)×Cavity Pressure (300–500 kg/cm2)Clamping Force (tons)=Projected Area (cm2)×Cavity Pressure (300–500 kg/cm2)
2. Select Machine Type Based on Needs
· Mass production → Two-platen hydraulic machines (cost-effective).
· High-precision/clean pallets → All-electric machines (medical/food grade).
· Special-function pallets → Multi-material machines (anti-slip, RFID).
3. Key Machine Features
· Screw design: Large diameter, high plasticizing capacity (L/D ≥ 20:1 for PP/HDPE).
· Mold compatibility: Must fit pallet mold size (min. mold thickness ≥ 600mm).
· Energy efficiency: Servo-driven or all-electric models save power costs.
4. Supplier Evaluation
· Experience: Do they have pallet production case studies?
· Support: Do they offer mold setup and process optimization?
· Smart features: Can the machine connect to MES/ERP systems?
