Composite materials—like Carbon Fiber Reinforced Polymer (CFRP) and pre-preg—are the backbone of modern high-performance industries. However, their complex, multi-layered structure makes them notoriously difficult to cut without compromising their integrity. Are you struggling with:
Your Current Pain Points | The Risk to Your Product & Business | The Shilai Solution |
Material Damage | Traditional cutting methods or dull tools cause fraying, delamination, or burrs on composite edges. | High-Speed Mirror Cutting: Ensures clean, smooth edges with zero fraying or burrs, maintaining structural integrity. |
Heat/Chemical Contamination | Laser cutting introduces heat, melting, odor, and material degradation (especially pre-preg). | Cold Blade Cutting: Uses Tungsten Steel Blades for a clean, mechanical cut with zero heat-affected zone (HAZ). |
Contamination & Dust | Cutting processes generate dust and debris, unsuitable for clean room or laboratory environments. | Zero-Contamination System: Dust-free cutting with an integrated cleaning system and full machine anti-static treatment. |
Low Precision & Waste | Manual cutting or poor nesting leads to high material waste and low accuracy. | Intelligent Nesting & Compensation: Smart layout system and Intelligent Error Compensation ensure 10%+ material utilization and high precision. |
Labor Shortages | High demand during peak seasons and difficulty in recruiting skilled manual cutters. | Automated Workflow: Supports single/multi-layer automatic feeding, boosting efficiency and reducing labor dependency. |
At Shilai, we understand that cutting composites is not just about speed—it's about preserving the material's structural and chemical properties. Our CNC knife cutting technology is specifically designed to meet the stringent quality standards of the aerospace, automotive, and power generation sectors.
1.Uncompromising Material Integrity (The Structural Guarantee):
Tungsten Steel Blade Technology: Our specialized Tungsten Steel Blades deliver a clean, precise cut that prevents the fraying and delamination common with other methods.
Cold Cutting Process: The mechanical blade cut is green, odorless, and free of heat-affected zones, making it ideal for sensitive materials like pre-preg and complex polymer structures.
2.Aerospace-Grade Precision & Efficiency (The Performance Driver):
High Precision: Utilizing a high-quality drive system, our machines achieve a cutting accuracy of ±0.1mm (material dependent), meeting the tight tolerances of high-tech manufacturing.
Intelligent Software Suite: Features like Intelligent Nesting and Intelligent Error Compensation maximize material yield and ensure consistent, high-quality output across the entire cutting area.
3.Clean Room Ready (The Safety & Quality Factor):
Zero Dust & Contamination: Our cutting process is inherently dust-free, and the equipment includes an integrated cleaning system. The full machine anti-static treatment prevents material attraction and ensures a clean, safe working environment, perfect for laboratories and high-spec production facilities.

Addressing the core concerns of procurement managers and production engineers in the composite industry:
Q1: Why is CNC knife cutting superior to laser cutting for carbon fiber and pre-preg?
A: Laser cutting uses heat, which can cause the resin matrix in composites to melt, burn, or release toxic fumes, severely compromising the material's structural integrity and creating a hazardous environment. Our CNC knife cutting is a cold, mechanical process that uses specialized blades to cut cleanly through the fibers and resin, ensuring zero thermal damage, no odor, and no material degradation.
Q2: How does your system prevent fraying and burrs on the edges of composite fabrics?
A: We use a combination of factors: 1) Specialized Tungsten Steel Blades designed for composite materials; 2) High-Speed Mirror Cutting technology for a clean shear; and 3) Intelligent Error Compensation to maintain precise cutting paths. This ensures a clean, smooth edge that requires minimal to no post-processing.
Q3: Can this machine be used in a clean room environment?
A: Yes. Our system is designed with zero-contamination in mind. It uses a dust-free cutting process, includes an integrated cleaning system, and the entire machine undergoes full anti-static treatment. This makes it perfectly suited for clean rooms, laboratories, and high-spec manufacturing facilities where contamination is a critical concern.
Q4: What kind of support do you offer for such specialized equipment?
A: We provide comprehensive technical support from our experienced engineers. Given the complexity of composite cutting, we strongly recommend a detailed solution consultation to configure the system (tooling, software parameters) precisely for your specific material and application (e.g., aerospace vs. automotive).
