Small draft-angle container, PET, clear, high-gloss finish, niddle-valve hot runner.

A draft angle in plastic molding refers to the taper applied to mold faces for easy part release. It is the angle between the vertical axis of the mold cavity and the vertical side of the part. Typically, a draft angle ranges from 1 to 2 degrees but can vary based on design and material.

However, a very small draft angle poses several technical difficulties:

1. Ejection Issues: Small angles increase friction, making it hard to eject parts without damage, leading to warping or breakage.
2. Increased Wear and Tear: High friction accelerates mold wear, reducing lifespan and requiring more frequent maintenance or replacement.
3. Surface Finish: Small draft angles can cause surface defects like drag marks or rough textures.
4. Demolding Force: Greater force is needed to eject parts, stressing the mold and machinery, potentially causing operational issues.
5. Mold Design Complexity: Precise engineering and tighter tolerances are required, increasing design complexity and costs.
