PEEK-Victrex PEEK 450CA30

Replacing aerospace-grade titanium and high-strength aluminum alloys in severe, load-bearing dynamic mechanisms without adding weight requires a polymer of unmatched specific stiffness, which Victrex’s PEEK 450CA30 delivers through its 30% carbon fiber reinforced, semi-crystalline polyetheretherketone matrix. Boasting a density of 1.40 g/cm³ and an extreme heat deflection temperature (HDT) of 335°C, this high-performance composite provides a massive flexural modulus of 21,000 MPa alongside inherent electrostatic dissipation (ESD) and near-zero wear. Jucheng Precision, operating under IATF 16949 and ISO 13485 certified frameworks, specializes in molding PEEK 450CA30. Supported by ceramic heater bands and pressurized oil mold heating controllers, we control its anisotropic shrink variables to prevent warpage, delivering structurally flawless parts verified by Zeiss CMM.

Victrex PEEK 450CA30 Structural Resiliency & Thermal Limits

Victrex™ PEEK POLYMER 450CA30 is a 30% carbon fiber reinforced semi-crystalline Polyetheretherketone, engineered to provide outstanding mechanical rigidity, dimensional stability, and exceptional thermal limits under ASTM/ISO standards:

Engineering Parameter Typical Value (DAM / ISO) Metal-Substitution Advantage
Structural Stiffness Tensile Modulus 23.0 GPa (23,000 MPa) Delivers extraordinary, metal-matching modulus at a low density (1.40 g/cm³), allowing for extreme weight-saving over titanium and aluminum.
Thermal Deflection (HDT) 335 °C (DAM @ 1.80 MPa) Ensures absolute dimensional stability and unyielding structural integrity under extreme continuous temperatures and dynamic load profiles.
Frictional & Wear Coefficient Extremely Low Wear & Friction Factor Highly resistant to continuous wear in high-speed, dry dynamic sliding interfaces. Perfect for unlubricated structural gearing.

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.

Pressurized Oil Mold Heating (Crystallization Control)

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
