Logistics pallets play a critical role in modern warehousing and transportation, especially under high-frequency handling and heavy-load conditions. TPO injection materials are gradually replacing traditional plastics due to their high strength, impact resistance, and lightweight nature.
Driven by the growing demand for performance, innovation in material and process integration becomes key. By optimizing injection structure and material formulation, pallet lifespan and safety can be significantly improved.
How Does TPO Injection Improve Load Capacity?
TPO’s molecular structure offers excellent rigidity support, and with appropriate injection design, it can significantly enhance the load-bearing capacity of pallets. Proper rib layout and wall thickness distribution are crucial for structural stability.
- Reinforced Structural Design: Enhances load capacity via rib and support optimization.
- Modified Material Formulas: Improves stiffness of polyolefin blends.
- Higher Injection Pressure: Increases density and strength of molded parts.
- Optimized Wall Thickness: Prevents deformation and enhances support.
How Does TPO Injection Enhance Impact Resistance?
Impact strength determines a pallet’s lifespan under extreme conditions like drops or collisions. TPO excels in low-temperature toughness and energy absorption. Accurate hot runner control during molding is key to achieving high impact strength.
- Elastic Modification Technology: Improves fracture toughness and flexibility.
- Controlled Cooling Rate: Prevents stress-induced cracking.
- Strengthened Corner Design: Reduces impact concentration points.
- Multi-Cavity Mold Application: Distributes stress and enhances durability.
How Can Injection Molding Optimize Pallet Performance?
Pallet performance relies not only on materials but also on stable, efficient molding processes. Temperature control, injection speed, and mold venting all directly affect product quality.
- Optimized Injection Speed: Balances fill quality and stress control.
- Melt Temperature Control: Ensures proper plastic flow and consistency.
- Precise Mold Venting: Prevents gas entrapment and cracking.
- Hold Pressure Adjustment: Stabilizes dimensions and prevents deformation.
