You need clear rules for vacuum casting rib boss design to achieve strong, high-quality parts. Follow these key guidelines for best results: Keep rib thickness less than 60% of the wall thickness. Limit rib height to less than three times the rib thickness. Make boss wall thickness no more than 60% of the wall. Use a minimum boss height and diameter of 1 mm. Apply these vacuum casting guidelines to boost part strength, prevent warping, and improve manufacturability. Key Takeaways Make sure rib thickness is less than 60% of the wall thickness. This helps make the part stronger and stops…
