PEEK Injection Molding Design Guide
Wall Thickness
- Uniform Wall Thickness: Aim for uniform wall thickness to minimize warping, sink marks, and internal stresses. Recommended thickness: 1.5–4 mm (0.06–0.16 in).
- Thin Walls: Avoid walls thinner than 0.5 mm (0.02 in) to ensure proper flow and part strength.
- Thick Walls: Avoid walls thicker than 6 mm (0.24 in) to prevent voids, sink marks, and long cooling times.
Draft Angles
- Include draft angles of 1–2° to facilitate part ejection and reduce wear on the mold.
Ribs and Bosses
- Ribs: Use ribs to increase stiffness without adding significant weight. Rib thickness should be 50–60% of the adjacent wall thickness.
- Bosses: Design bosses with adequate wall thickness and consider using gussets for reinforcement.
Radii and Fillets
- Use generous radii and fillets (minimum 0.5 mm or 0.02 in) to reduce stress concentrations and improve flow.
Gate Design
- Use larger gates to accommodate PEEK’s high viscosity. Common gate types include edge gates, tab gates, and submarine gates.
- Position gates to ensure uniform filling and minimize weld lines.
Shrinkage
- PEEK has a low shrinkage rate (1–2%), but this can vary depending on the grade (e.g., unfilled, glass-filled, or carbon-filled). Account for shrinkage in the mold design.
