Mold & Die Micromachining

We empower the high-end mold industry with advanced femtosecond laser technology. From process design to equipment optimization, we provide full-cycle support to overcome micro-nano processing challenges. Our solutions ensure superior precision and durability for next-generation mold manufacturing.

Key Applications

1. Roller Imprint Mold Texturing

Capability: Precision etching of complex micro-structures (micro-bosses, hexagons, grooves) on cylindrical rollers.

Outcome: No thermal distortion. Compatible with hardened metals and ceramics, ensuring high durability for long-term mass production.

2. Injection Mold Micro-Hole Drilling

Breakthrough: Achieves high aspect ratio holes (10:1) with clean edges (Ra < 0.2μm). No secondary polishing required.

Efficiency: Drills tens of holes per minute. Ideal for high-density air venting holes and cooling channels, significantly improving molding consistency.

3. Light Guide Plate Etching

Precision: Fabricates sub-micron optical structures (prisms, crescents, V-grooves) with absolutely no recast layer.

Outcome: Guarantees uniform light distribution and high optical efficiency, supporting the production of premium display components.

4. Contact Lens Mold Inserts

Quality: Sub-micron patterning with zero heat damage, preserving the material integrity required for medical-grade products.

Flexibility: Enables rapid prototyping and iteration for customized optical designs and the medical aesthetics market.

Why Choose Femtosecond Laser?

1. Cold Ablation: Zero Heat Damage

Leveraging ultra-short pulses (10⁻¹⁵ seconds), our laser vaporizes material instantly. This "cold processing" eliminates the Heat Affected Zone (HAZ), preventing annealing, warping, or micro-cracks common in traditional EDM or long-pulse laser processing.

2. Sub-Micron Precision & Surface Quality

Accuracy: High-stability servo systems ensure positioning accuracy of ±1μm.

Finish: Achieves surface roughness of Ra < 0.2μm for etching and Ra < 0.4μm for cutting.

Result: Parts are produced with no burrs or recast layers, eliminating the need for post-process polishing or chemical cleaning.

3. Complex 3D Structuring

Break through the limitations of mechanical drilling. We support:

High Aspect Ratio: Up to 10:1 depth-to-diameter ratio.

Complex Shapes: Inclined holes, helical holes, and micro-nano arrays (prisms/grooves) in a single pass.

Large Format: Stitching accuracy ≤ 1μm for large molds (>350mm×350mm).

4. Material Compatibility

Eliminate the need to switch tools for different materials. Our technology works seamlessly on:

Hard Metals: Tungsten steel, Titanium alloys, Stainless steel.
