Ming-Li Precision Manufactures Aerospace-Grade PEEK Stator Coil Retaining Ring for TASA

Delivering NASA-Level Precision in High-Performance Injection Molding

Taichung, Taiwan — Ming-Li Precision Steel Molds Co., Ltd., a globally recognized specialist in PEEK injection molding and high-precision insert molding, proudly announces the successful manufacturing of an aerospace-grade PEEK stator coil retaining ring for Taiwan’s National Space Organization (TASA).

This project demonstrates Ming-Li Precision’s capability to meet NASA-level engineering standards, supporting mission-critical applications where failure is not an option.

Engineering for Space: Where Precision Meets Performance

Aerospace components demand extreme reliability under harsh conditions such as:

High thermal cycling
Vacuum environments
Mechanical stress and vibration
Long-term dimensional stability

The stator coil retaining ring produced for TASA is designed to meet these rigorous requirements, serving as a critical structural and positioning component within high-precision electromagnetic systems.

Why PEEK is the Material of Choice for Aerospace

PEEK (Polyether Ether Ketone) is one of the most advanced engineering thermoplastics available today, widely used in aerospace and satellite systems.

Key advantages:

Continuous operating temperature up to 250°C
Exceptional strength-to-weight ratio
Outstanding wear and fatigue resistance
Excellent electrical insulation
Low outgassing properties (critical for space applications)
Resistance to aggressive chemicals and radiation

These properties make PEEK an ideal material for lightweight, high-performance aerospace plastic components.

Mastering Thin-Wall PEEK Injection Molding (1 mm Thickness)

One of the most challenging aspects of this project is the ultra-thin wall design of only 1 mm, combined with complex geometry and precision mounting features.

Key challenges overcome:

Maintaining uniform flow in thin-wall sections
Preventing warpage and shrinkage variation
Achieving tight tolerances for assembly fit
Ensuring structural integrity under load

Ming-Li Precision successfully addressed these challenges through:

Advanced Moldflow simulation and optimization
Precision mold manufacturing using YASDA 5-axis CNC (±1 µm accuracy)
Stable high-temperature PEEK molding process control
Real-time quality monitoring and statistical process control (SPC)

Aerospace-Grade Quality Assurance

To meet aerospace standards, Ming-Li Precision implemented a rigorous inspection and validation process:

ZEISS CMM measurement systems for micron-level dimensional verification
ZEISS 3D X-ray CT scanning for internal structure analysis (non-destructive inspection)
Full traceability of materials and production batches
FAI (First Article Inspection) and continuous production monitoring

This ensures every component meets the highest standards of precision, consistency, and reliability.
