Molding Analysis: PEEK 450CA30 Tooling Design & Fiber Orientation Guide
Molding an ultra-high performance carbon-fiber reinforced PEEK like 450CA30 requires extreme thermal boundaries and advanced PM-hardened molds to prevent wear:
Powder Metallurgy Hardened Tool Steel
30% short carbon fibers act as an aggressive grinding agent under high injection pressures and melt viscosity (480 Pa·s). Jucheng’s tooling division prevents gate and cavity erosion by using premium CPM powder metallurgy tool steels or hardened H13/S136 steel (HRC 54–56) with PVD ceramic coatings.
Managing Anisotropic Shrinkage & Warpage
PEEK 450CA30 exhibits almost zero shrinkage in the flow direction (typically 0.10%) but higher shrinkage perpendicular to the flow (0.40%). We conduct detailed Moldflow analysis during DFM to locate gates, ensuring uniform fiber orientation to prevent structural warping.

To secure the proper semi-crystalline phase, mold temperatures must be maintained continuously at 175°C–205°C (347°F to 401°F) using pressurized oil-heating controllers. Cold molds prevent crystallization, resulting in amorphous parts with low chemical resistance and weak structural strength.
Melt & Moisture Controls
Processing melt temperatures are maintained between 370°C and 390°C (698°F to 734°F). To prevent splay, we dry the raw resin in desiccant hopper dryers at 150°C (302°F) for 3–4 hours, keeping internal moisture below 0.02% to secure optimal molecular bonds.
Key Application Fields for PEEK-Victrex PEEK 450CA30
