Custom PEEK Parts
Plasticpartsmfg engineers and manufactures mission-critical PEEK (Polyetheretherketone) components directly from your CAD models and 2D engineering drawings. From single rapid prototypes and validation samples to scheduled low-volume production runs, we provide precision CNC machining, high-temp injection molding, and industrial 3D printing tailored to stringent thermal, mechanical, and dielectric tolerances.

Why Engineers Choose Plasticpartsmfg for Critical PEEK Parts
PEEK requires rigorous thermal control, sharp tooling, and specific stress-relief protocols to prevent dimensional distortion and micro-cracking.
Controlled Annealing Cycles
Uncontrolled machining heat causes residual internal stresses. We implement dedicated pre-machining and post-machining ramped annealing to guarantee long-term stability and structural cohesion under thermal cycling.
High-Temp Barrel Molding
With processing temperatures reaching 400 °C and mold temperatures exceeding 160 °C, our specialized high-heat molding machines maintain exact crystalline development for peak tensile and wear resistance.
Strict Metrology & Traceability
Every critical feature is verified on calibrated CMMs and 2.5D optical measuring instruments. Full material mill certs, raw material lot documentation, and dimensional FAI reports are supplied with each shipment.
