Description
Mica CNC Machined Parts are precision components manufactured from high-quality rigid mica sheets (muscovite or phlogopite) using advanced CNC turning, milling, and cutting machines. These parts are ideal for applications requiring high mechanical strength, excellent dielectric insulation, and high-temperature resistance.
Common shapes include gaskets, washers, flanges, tubes, discs, and other custom designs according to customer specifications. CNC machining allows for tight tolerances (±0.2 mm), smooth edges, and high-quality finishes, suitable for both prototypes and mass production.
Features
High Temperature Resistance: Continuous use up to 1000°C, suitable for high-temperature insulation
Electrical Insulation: Excellent dielectric strength and flame resistance
Mechanical Strength: Durable under mechanical stress, suitable for industrial and electrical applications
Precision & Tolerance: CNC machining ensures high dimensional accuracy (±0.2 mm)
Custom Shapes: Supports gaskets, washers, flanges, tubes, discs, and other designs
Flexible Production: Suitable for prototypes, small batches, and large-scale production
Smooth Edges: Minimizes burrs and chipping for high-voltage or critical applications
Applications
Mica parts are widely used in industries such as:
Home Appliances: Heating element supports, gaskets, insulation
Automotive & Marine: Electrical insulation, high-temperature seals
Electromagnetic Equipment: Components requiring precise dielectric isolation
Military & Aerospace: High-temperature, high-voltage applications requiring flame-resistant parts
They are suitable for heating element supports, insulation layers, gaskets, and seals, especially in environments with high temperatures and electrical stress.
Processing Overview
Confirm Requirements: Verify material type, thickness, CAD drawings, quantity, and tolerance.
Select Processing Method:
Prototypes & small batches → CNC or Laser Cutting
Mass production → Mold tool punching (thin mica, 0.3–2.0 mm)
Medium/thick mica → Waterjet or CNC
Prototype Development: Produce and inspect samples for dimension, edge quality, and functionality.
Mold Fabrication (if required): Design hardened steel molds for high-volume production.
Mass Production: Execute full batch production, followed by strict quality checks.
Post-Processing: Deburring, polishing, and cleaning to ensure smooth surfaces and safe handling.
Technical Data Sheet
| Common Mica Processing & Cutting Methods | |||
| A. For Thin Mica Sheets (0.1mm – 1mm) | |||
| Method | Best for | Pros | Cons |
| Die Punching | Mass production (1,000+ pcs) | Fast, low cost per part | High mold cost, not for thick mica |
| Laser Cutting | Prototypes & small batches | No tooling needed, high precision | Slight charring on edges |
| Waterjet Cutting | Medium-thick mica (0.5-5mm) | No heat, smooth edges | Slower, higher cost |
| Ultrasonic Cutting | Thin mica (<1mm) | Clean cuts, no dust | Limited to very thin sheets |
| B. For Thick Mica Plates (1mm – 10mm+) | |||
| Method | Best For | Pros | Cons |
| CNC Machining | High-precision parts | Tight tolerances (±0.05mm) | Slower, higher cost |
| Waterjet Cutting | Thick mica (3mm+) | No thermal stress, smooth edges | Slower than laser |
| Diamond Saw Cutting | Simple shapes, thick mica | Fast for straight cuts | Rough edges, needs polishing |
