Two-Plate Cold Runner Injection Mold Design
This case study showcases a typical two-plate cold runner injection mold design featuring a sub-gate (submarine gate) system. Developed through a full 3D parametric workflow, the project demonstrates the engineering logic behind the gating system, ejection mechanism, and cooling circuits, serving as a technical reference for general-purpose plastic injection mold design.
Key Design Parameters & Technical Highlights

Two-Plate Mold: Design Perspective Analysis
Design Advantages
In this two-plate mold design, the simplified structure minimizes moving components and interference risks. Combined with a sub-gate system, the design eliminates the need for secondary gate trimming, facilitating downstream automation layouts.
Design Considerations
Unlike sub-gates or banana gates, conventional gating methods often require reserved space for post-processing. During the injection mold design phase, engineers must evaluate cosmetic requirements and compatibility with automated part handling systems.
