Injection Mold Design Guide -

| Feature | Movement direction | Max stroke | Typical actuator | |---------|-------------------|------------|------------------| | Slide (cam pin) | Perpendicular to open | 20–60 mm | Angular pin or hydraulic | | Lifter | Angled (core pull) | 5–20 mm | Ejector plate + angle pin | | Collapsible core | Inward radial | Large (threads) | Mechanical / hydraulic |

Angle rules:

Ribs provide stiffness without adding thickness. A 3mm thick wall is heavy and slow to cool. A 2mm wall with a 1.5mm rib is lighter and stronger. injection mold design guide

Injection molding is a high-volume manufacturing process for producing plastic parts by injecting molten polymer into a mold cavity. Good mold design optimizes part quality, reduces cycle time, and minimizes production costs. This guide covers essential design considerations, tooling elements, material selection, and common best practices. | Feature | Movement direction | Max stroke

Cooling channels should be placed 3x the channel diameter from the mold surface. Injection molding is a high-volume manufacturing process for
