Precision CNC Machined & Custom Fabricated Mica Components

Machined Mica Parts are produced via CNC turning, 3D forming, and automatic stamping with ±0.02mm precision tolerance. They support all three mica grades (muscovite/phlogopite/synthetic), are UL94 V-0 flame retardant, and are ideal for motors, transformers, EV batteries, and aerospace engine bays. Custom Mica Components (Fabricated Mica Parts) are produced via laser cutting, water-jet cutting, and polishing — optimized for high breakdown voltage applications (120-200 kV/mm muscovite), thermal shielding in aerospace, chemical equipment liners, and semiconductor manufacturing.

We offer a complete suite of precision manufacturing: CNC turning centers for rotational parts, laser engraving for complex patterns, 3D forming for curved geometries, automatic stamping for high-volume production, laser cutting and water-jet cutting for sheet fabrication, plus polishing and specialty surface treatments. Each method is matched to your geometry, tolerance, and production volume needs.

Our standard tolerance is ±0.1mm for most machined parts. For critical applications requiring tighter control, we offer precision grade ±0.02mm with dedicated grinding operations. Surface finish options include smooth (Ra ≤0.8μm) for low-friction assemblies, or textured finish for enhanced bonding in composite applications. Send us your drawing tolerance callouts — we'll confirm achievable specs within 24 hours.

Yes. We provide collaborative R&D design consultation and mold development support for OEM customers. Share your application requirements (operating temp, voltage, mechanical load, environment) — our engineering team will recommend the optimal mica grade, manufacturing process, and critical design features. We have extensive experience developing high-value specialty products for motor/transformer/aerospace OEMs.

For Machined Mica Parts: length/width 5-500mm, thickness 0.1-10mm. Custom CNC turning can handle larger rotational parts. For Custom Mica Components (laser/water-jet): we can cut from full sheets or any custom geometry per your CAD drawing. If your part falls outside standard ranges, contact us — we frequently handle non-standard dimensions for specialty applications.

For prototype/sample runs: MOQ 10-50 pcs, lead time 7-14 days (including design review and material preparation). For standard custom parts (CNC or laser): MOQ 100-500 pcs, lead time 15-25 days. For high-volume OEM (automatic stamping): MOQ 1000+ pcs, lead time 25-35 days with consolidated shipments. Rush production available with small surcharge. We offer VMI (vendor-managed inventory) for ongoing OEM customers.
