Molds for pet products typically have rounded edges (R ≥ 2 mm) to avoid sharp corners. Cavity surface finish is required to be Ra ≤ 0.8 μm for easy cleaning. Draft angles are generally 0.5° or more; textured surfaces require larger angles. Non‑slip patterns on the bottom of bowls are formed by engraving on the mold base. Common materials are PP or PE, and the cavity can be made of S136 or 718H steel.
