Proceso: Step-by-Step PEEK Injection Molding
PEEK’s unique properties require a highly controlled injection molding process—even minor deviations in temperature or pressure can compromise part quality. Below is our optimized PEEK molding cycle, designed to maximize consistency and performance:
Paso 1: Preparación de material (El secado)
PEEK is hygroscopic (absorbe la humedad), which causes bubbling and voids in finished parts. We dry PEEK pellets in a dehumidifying dryer at 150 ° C para 4 horas (critical for maintaining material integrity). For medical-grade PEEK, we use nitrogen-purged dryers to prevent contamination.
Paso 2: Diseño de moldes & Preparation
- Gate & Runner Design: We use hot runners (instead of cold runners) to minimize PEEK waste (hot runners keep material molten, reducing scrap by 25–30%). Gates are placed to avoid shear stress (PEEK is sensitive to excessive shear, which degrades its strength).
- Control de la temperatura del molde: Molds are heated to 150–200 ° C (via oil or electric heaters) to promote uniform crystallization—this ensures estabilidad dimensional and prevents warping. Para partes gruesas, we use gradient heating (warmer at the core, cooler at the surface).
Paso 3: Injection Molding Machine Setup
- High-Heat Barrel Settings: Barrel zones are set to a temperature gradient (feed zone: 360 ° C; melt zone: 380–400 ° C; boquilla: 390–410 °C) to melt PEEK without thermal degradation.
- Inert-Gas Venting: We purge the mold cavity with nitrogen during injection to remove air (PEEK’s high viscosity traps air easily, leading to defects). This step is mandatory for parts like semiconductor clamps (where even tiny voids cause failure).
Paso 4: Inyección & Packing
- Velocidad de inyección: Slow to moderate (50–100 mm/s) to control shear (excessive shear reduces PEEK’s tensile strength by 10–15%).
- Packing Pressure: 80–90% of injection pressure, held for 10–20 seconds to compensate for shrinkage (PEEK shrinks 1.5–2.5% during cooling).
Paso 5: Enfriamiento & Fundamento
El tiempo de enfriamiento varía según el grosor de la parte (10 seconds for thin parts, 60 seconds for thick sections). We use controlled cooling to maintain crystallinity (objetivo: 35–40% for most applications; higher for structural parts, lower for flexible components). Demolding is done with gentle ejectors to avoid scratching (crítico para implantes médicos).
Paso 6: Postprocesamiento & Control de calidad
- Recocido: Parts are heated to 180–200 °C for 1–2 hours, luego se enfrió lentamente (5 ° C/min) to relieve internal stresses. This step improves dimensional stability by 20–25%.
- SPC Monitoring: We use Statistical Process Control (proceso estadístico) to track key parameters (temperatura, presión, Tiempo de ciclo) en tiempo real. Any deviation beyond ±2% triggers an alert, asegurar una calidad consistente.
Inspección: Parts undergo dimensional testing (Cmm), mechanical testing (tensile strength per ASTM D638), e inspección visual (for defects like flash or voids).

PVD/CVD Coatings | Applying hard coatings (P.EJ., carburo de tungsteno) via PVD/CVD | Resists scratches and chemical attack | Aceite & gas down-hole parts, corchetes aeroespaciales |
Bondable Primer | Applying a polyurethane primer to PEEK surfaces | Enables strong bonding to metals/plastics | Multi-material assemblies (P.EJ., carcasa electrónica) |
Sterilization-Compatible Finish | Heat-curing a silicone-based coating | Soportes 1,000+ ciclos de autoclave (134 ° C, 3 bar) | Reusable medical instruments |

Ventajas: Why PEEK Injection Molding Outperforms Alternatives
PEEK Injection Molding offers a unique set of advantages that make it irreplaceable in critical applications. Compared to metals (acero, aluminio) and other plastics (Pensilvania, PPS), PEEK delivers unmatched value:
Key Advantages of PEEK
- Extreme Temperature Resistance: PEEK maintains 90% of its strength at 240 ° C (uso continuo) and can withstand short-term exposure to 300 ° C. This outperforms aluminum (loses strength at 200 ° C) y PPS (continuous use limit: 200 ° C).
- Chemical Inertness: Resistente a los aceites, solventes, ácidos, y bases (even concentrated sulfuric acid at room temperature). A diferencia de los metales, it won’t corrode—ideal for oil & gas and chemical processing parts.

Nuestro pulido (Real academia de bellas artes <0.1 µm) process created a mirror-smooth surface that prevented particle buildup, y in-house mold-flow analysis designed the housing with thin, uniform walls (avoiding hot spots during molding). También agregamos un Revestimiento resistente a los rayos UV to protect against cleanroom lighting.
Resultado: The PEEK housing survived 50+ solder bath cycles (260 ° C para 10 minutos) without warping or discoloration. Its low outgassing kept wafer defect rates below 0.01%—a critical requirement for advanced chip manufacturing. The client replaced all metal housings with PEEK, cutting robot weight by 30% and improving maneuverability.
