As the automotive industry evolves towards higher efficiency and hybridization, precision manufacturing is the key to performance breakthroughs. With increasingly stringent global emission regulations and the drive for fuel economy, the upgrade of fuel injection systems has become a critical competitive field.

Leveraging the "Cold Ablation" and micro-nano control capabilities of femtosecond lasers, we solve nozzle drilling challenges that traditional methods cannot match, empowering the modernization of core automotive components.

Superior "Cold Ablation" Quality

Utilizing the non-linear effects of ultra-short pulses, our process vaporizes material instantly before heat can diffuse, resulting in a minimal Heat Affected Zone (HAZ <1μm) that is completely free from recast layers or micro-cracks. This creates a mirror-smooth inner wall that ensures perfect fuel atomization, effectively eliminating the need for expensive post-process hydro-erosive grinding.

Custom Taper Control: Inverse, Positive, & Zero Taper

Since hole taper critically defines flow velocity and cavitation, our technology overcomes the inability of traditional methods to produce complex geometries like inverse taper holes (smaller inlet, larger outlet). Through advanced beam shaping and spatial angle adjustment, we achieve precise taper control ranging from 0 to 1.15°, enabling the accurate formation of positive, zero, and high-performance inverse taper profiles to optimize engine performance.

High Precision in 3D Space

We extend this micro-machining capability to complex 3D curved surfaces, maintaining a comprehensive accuracy of ±1μm across circularity, depth, and hole-to-hole consistency. This ensures that the angle and position of every spray hole strictly adhere to the most demanding hydrodynamic designs, ultimately maximizing overall combustion efficiency.

Beyond fuel systems, femtosecond precision is unlocking new potential in New Energy Vehicles and high-end mold making. From ensuring burr-free cutting of battery electrodes to enabling digital 3D mold texturing without chemical etching, our technology delivers sub-micron accuracy, empowering the industry's shift toward electrification and premium quality.
