Key Design Highlights for 20L Bucket Mold:
For heavy-duty 20L paint buckets, wall thickness uniformity and eccentricity control are critical to prevent leakage during stacking. Our mold design utilizes an optimized central cooling system and premium 718H steel to ensure the bucket withstands rigorous drop tests. The lid mold features a precise strip-off ejection mechanism to ensure fast cycle times without deforming the sealing rib.
