0.25mm Mobile Phone Glass Cover Laser Cutting Solution

1. Background

In the mobile phone glass cover processing industry, traditional CNC mechanical machining has long been the dominant method. While this approach is mature, it faces multiple challenges that are increasingly difficult to overcome: cutting fluids cause environmental pollution, tools such as drill bits wear out quickly, machining efficiency is low, and the process requires significant equipment, manpower, and factory space — all of which lead to high production costs.

In recent years, with the growing demand for thinner and more precise glass components, laser cutting technology has become a preferred alternative, offering cleaner, faster, and more precise results for 0.25mm mobile phone glass cover production.

2. Customer Requirement

The customer required cutting 0.25mm thick mobile phone glass covers from original sheets into customized sizes, with strict quality demands: smooth edges, no chipping, consistent size and shape, and a yield rate above 99%. The process also needed to support batch processing with high stability and minimal maintenance.

3. Laser Cutting Solution

The ideal solution is a infrared picosecond laser glass cutting system, designed specifically for high-precision micro-processing of thin glass materials.

This system combines a high-frequency picosecond laser source, precision motion platform, and intelligent vision positioning system. It uses a non-contact cutting process, focusing high-energy laser beams onto precise cutting points to generate controlled micro-cracks within the glass, achieving a clean and precise separation without mechanical stress.

Key Advantages:

• Non-contact processing: Eliminates mechanical stress and prevents secondary damage or deformation.

• Ultra-fast laser pulse: The picosecond laser acts instantly, causing material vaporization or micro-explosion with minimal heat impact.

• High precision: Cutting accuracy up to ±0.01mm, edge roughness < 5μm, and high perpendicularity.

• Flexible shape cutting: Supports circular, square, curved, and irregular outlines in a single process.

• Batch production: With an automated platform, multiple pieces can be processed simultaneously, increasing efficiency up to 3 times.

• No post-processing: Smooth, clean edges require no additional polishing or grinding.

This laser cutting approach significantly improves production efficiency, stability, and yield rate, making it a cost-effective and environmentally friendly alternative to CNC machining.
