Deep Draw Core Design
Crates are typically deep parts. Core cooling, draft angles, surface finish and ejection mechanism must be carefully designed for reliable part release without deformation.
Plastic Crate Injection Mold
Custom injection mold for plastic crates, boxes and containers used in logistics, storage and industrial material handling applications.
Overview
Plastic crates are workhorse products in logistics, agriculture and industrial material handling. The mold must produce durable parts with consistent dimensions, reliable stacking features and efficient cycle times for high-volume production.
Shengqi reviews the crate design including overall dimensions, grid or solid wall pattern, bottom structure, stacking lugs, handle openings, labeling area and reinforcement ribs before mold design.
For large crates, mold filling analysis, cooling efficiency and ejection force distribution are critical to achieving stable production and acceptable cycle times.
Engineering Focus Areas
Rib Network and Weight Optimization
Structural ribs provide strength while minimizing material weight. Rib thickness, spacing, height and intersection design affect both part performance and molding quality.
Stacking Feature Precision
Stacking lugs and interlock features must engage reliably across multiple crates. Mold precision at these features affects product usability in automated handling systems.
High-Volume Production Readiness
Crate molds typically run high volumes. Hot runner systems, multi-cavity layouts, fast cycling and automated part removal are considered for production efficiency.
