Product Overview
This is a high-performance 1×1 cavity injection mold purpose-built for manufacturing heavy-duty plastic crates (stackable storage/transport containers). Designed for mass production of logistics-grade parts, this mold combines precision engineering, durable tool steel construction, and optimized ejection systems to deliver consistent, high-quality crate parts with excellent structural integrity and dimensional stability.
Key Mold & Product Features
✅ Heavy-Duty Tool Steel Construction
Built with premium mold steel (typically 1.2344 / H13 or equivalent), heat-treated for wear resistance and thermal stability, ensuring a mold life of up to 1,000,000+ cycles for high-volume production.
✅ 1×1 Cavity High-Volume Design
Single-cavity configuration allows for large, full-size crate molding with optimized cycle times, balancing production efficiency and part quality for industrial-grade applications.
✅ Optimized Cooling & Warpage Control
Precision-engineered cooling channels ensure uniform temperature distribution, minimizing warpage and shrinkage on the crate’s large flat surfaces, which is critical for stackability and dimensional accuracy.
✅ Robust Ejection System
Equipped with multi-point pin ejection and dedicated hydraulic/mechanical lifters, ensuring smooth, damage-free part release even for deep-draw crate geometries.
✅ Stackable & Structural Geometry
Designed to form integrated reinforcement ribs, corner supports, and stacking features, ensuring the final crate has excellent load-bearing capacity and interlocking stability for logistics use.
✅ Versatile Material Compatibility
Optimized for PP (Polypropylene) and HDPE (High-Density Polyethylene), the most common materials for durable, impact-resistant plastic crates.
