Zinc Die Castings Design
| Design Elements | Specific Value/Range | |||
| Uniform Wall Thickness | Aim for wall thickness between 1.5mm to 4mm for optimal casting flow and to reduce material wastage. | |||
| Draft Angles | Use a 1° to 3° draft angle on vertical surfaces to ease part removal and prevent damage to the mold. | |||
| Radii and Fillets | Incorporate 2mm to 4mm radii at corners and edges to improve flow and reduce stress concentrations. | |||
| Avoid Sharp Corners | Sharp corners can cause stress and are difficult to cast. Use a minimum 2mm radius to improve moldability. | |||
| Incorporate Ribs and Bosses | Design ribs with a thickness of 0.5mm to 1mm and maintain proper spacing (2-3 times the thickness) for strength without adding excessive material. | |||
| Correct Gate Placement | Gates should be placed at the thickest sections, and the gate thickness should be about 1mm to 2mm to ensure even metal flow and avoid cold shuts. | |||
| Optimized Thickness for Strength | For balance, wall thickness should be between 1.5mm to 4mm, ensuring a lightweight and durable part. | |||
| Proper Tooling Design | Vents should be spaced about 30mm to 50mm apart, with runners about 5mm to 7mm wide to ensure proper air evacuation and metal flow. | |||
| Consider Post-Processing Needs | Allow for 0.1mm to 0.3mm tolerance for any CNC machining or secondary finishing, such as polishing or painting. | |||
| Avoid Deep Blind Holes | Avoid blind holes deeper than 2-3 times their diameter. If needed, use through holes to simplify casting. | |||
| Minimize Undercuts | Minimize undercuts in the design to reduce complexity in tooling. Consider using side-action tooling or simplifying the design. | |||
