How Design Affects Quality
Silicone mold design determines product quality, detail accuracy, and production efficiency.
| Design Factor | Impact on Quality |
|---|---|
| Wall thickness | 3-5mm (0.1 in–0.2 in) prevents tearing |
| Draft angle | 2-5 degrees improves demold |
| Undercut depth | Affects mold flexibility need |
| Surface finish | Pattern quality transfers to mold |
Structure Design Elements
| Element | Recommendation |
|---|---|
| Wall thickness | Minimum 3mm (0.1 in), edges 5mm (0.2 in) |
| Draft angle | 2-5 degrees for easy demold |
| Undercut handling | Split mold for complex shapes |
| Support structure | Mother mold for thin sections |
Production Efficiency
Good design improves production efficiency:
- Fast demold reduces cycle time
- Consistent quality reduces rejects
- Longer mold life reduces cost
- Simple structure speeds casting
