Custom PEEK Injection Molding Services
Plasticpartsmfg provides precision custom PEEK (Polyetheretherketone) injection molding services for mission-critical applications demanding exceptional thermal stability, chemical inertness, and structural strength.
Operating from our advanced manufacturing facility in Shenzhen, China, we support engineering teams and procurement specialists through every phase—from rapid prototype tooling and DFM optimization to full-scale automated production runs.
PEEK Injection Molding Capabilities
PEEK is a high-temperature, semi-crystalline polymer requiring specialized barrel metallurgy and high-mold-temperature control. Our production cells ensure optimal crystallinity, zero voids, and strict dimensional stability.
| Capability Metric | Standard & Advanced Specification |
|---|---|
| Process Technology | High-temperature injection molding with closed-loop process monitoring |
| Material Formulations | Unfilled (neat), 30% Glass-filled, Carbon-filled, Bearing/Wear grades |
| Machine Clamping Tonnage | 50 to 450 metric tons |
| Typical Achievable Tolerances | ±0.05 mm to ±0.20 mm (contingent on part geometry and reinforcement) |
| Tooling Steels | Pre-hardened & through-hardened tool steels (H13, NAK80, S136) |
| Production Batch Volumes | Low-volume bridge production to scalable mass production runs |
| Secondary Operations | Annealing, precision CNC post-machining, cryogenic deburring, insert assembly |
Why Choose PEEK for Critical Components
Engineers frequently specify PEEK to replace metals such as titanium, stainless steel, and aluminum in harsh environments, unlocking substantial weight reduction without compromising strength.
Thermal Stability
Maintains mechanical integrity under continuous service temperatures up to 250°C (482°F) and resists short excursions up to 300°C.
Chemical Resistance
Resistant to a vast spectrum of organic and inorganic reagents, automotive fluids, industrial solvents, steam sterilization, and gamma radiation.
Mechanical Strength
Delivers superior tensile modulus, fatigue endurance, and impact resistance, offering one of the highest strength-to-weight ratios in polymer engineering.
Electrical Insulation
Inherent dielectric properties retain high breakdown voltage and low dissipation factors across broad temperature and humidity variations.
Biocompatibility
Compatible with stringent biological evaluation standards, making it the preferred choice for surgical tools, dental items, and diagnostic hardware.
Wear & Friction
Low coefficient of friction and high wear endurance allow non-lubricated operation in dynamic mechanical assemblies and pumps.
Our Manufacturing Process
Transitioning high-cost engineering polymers from digital design into defect-free molded parts requires rigorous thermal discipline. Explore each phase of our controlled workflow:
Material Selection & DFM Analysis
PEEK represents an investment in high-performance raw material. We conduct thorough CAD audits early in development to pinpoint optimal gate placement, balance uniform wall sections, and optimize draft angles. This proactive engineering mitigates residual stress, prevents sinks, and minimizes scrap volume.
- Part geometry simplification for uniform flow front progression
- Selection of unfilled, glass-reinforced, or carbon-fiber composite variants
- Moldflow simulation to forecast shear stress and weld line behavior
Typical Applications
We manufacture custom PEEK components across demanding industries where component degradation or mechanical failure is not an option:
Medical & Laboratory
Autoclavable surgical instruments, diagnostic equipment manifolds, and precision dental components.
Industrial Equipment
High-wear non-lubricated gears, chemical pump impellers, valve seats, and high-load bushings.
Aerospace & Automotive
Weight-saving structural brackets, fuel system containment parts, and sensor enclosures.
Electronics & Semi
Semiconductor wafer-handling arms, high-voltage connector isolators, and test sockets.
