Laser sheet cutting uses a high-power fiber laser beam to precisely cut flat metal sheets into custom shapes and profiles. The process is controlled by CNC programming, ensuring repeatable accuracy across every part — whether you need 10 prototypes or 100,000+ production pieces.

At Conwhole, we operate advanced fiber laser cutting systems capable of processing sheets up to 6,000 × 2,000 mm with tolerances as tight as ±0.01 mm. Our in-house capability means faster turnaround, lower costs, and complete quality control from raw material to finished part.

Key Takeaways:
– Fiber laser technology delivers clean edges with mininal heat-affected zone
– Material thickness range: 0.5 mm to 40 mm
– Maximum sheet size: 6,000 × 2,000 mm
– Tolerance: ±0.01 mm for precision applications
– Suitable for stainless steel, carbon steel, aluminum, brass, and copper
– No tooling required — ideal for rapid prototyping and custom designs

Step 1: Drawing Review & DFM Analysis
Our engineers review your CAD files (DXF, DWG, STEP) and provide Design for Manufacturing feedback to optimize part geometry, reduce material waste, and ensure cut quality.

Step 2: Material Preparation

Raw metal sheets are inspected for thickness, flatness, and surface quality. Material certificates are verified to meet your specification requirements.

Step 3: CNC Programming & Nesting
Using advanced nesting software, we arrange parts on the sheet to maximize material utilization — typically achieving 85-95% yield. CNC programs are generated and simulated before cutting.

Step 4: Laser Cutting
The fiber laser cuts parts with precision and speed. Assist gas (nitrogen for clean edges, oxygen for faster cutting) is selected based on material and application requirements.

Step 5: Quality Inspection
Cut parts are inspected for dimensional accuracy, edge quality, and surface finish. First-article inspection reports are provided for approval before full production.

Step 6: Finishing & Delivery
Parts are deburred, cleaned, and prepared for the next manufacturing step or direct shipment. Optional surface treatments (powder coating, anodizing, plating) can be coordinated in-house.

Laser cutting is just the beginning. We handle bending, welding, stamping, CNC machining, and surface finishing — all under one roof. No need to coordinate multiple suppliers.

Our 12,000W fiber laser systems deliver faster cutting speeds and thicker material capacity than most competitors, reducing your lead time and cost.

Our team provides free DFM analysis, material recommendations, and design optimization to ensure your parts are manufactured efficiently and cost-effectively.

ISO 9001 certified processes, first-article inspection reports, and full traceability from raw material to finished part. Every shipment meets your specifications.

Q1: What file formats do you accept for laser cutting?
We accept DXF, DWG, STEP, IGES, and PDF files. For best results, provide 2D vector files (DXF/DWG) with clear layer definitions for cutting lines, engraving, and marking.

Q2: What is the minimum order quantity (MOQ)?
We support orders from 1 piece for prototypes to 100,000+ pieces for mass production. There is no minimum order requirement — we work with your project needs.

Q3: What materials can you laser cut?
We cut stainless steel (304, 316, 430), carbon steel (Q235, SPCC, A36), aluminum (1060, 5052, 6061), brass, copper, and galvanized steel. Thickness range: 0.5 mm to 60 mm depending on material.

Q4: How tight are the tolerances?
Standard tolerance is ±0.1 mm. For precision applications, we can achieve ±0.01 mm on thin-gauge materials. Tolerance depends on material type, thickness, and part geometry.

Q5: What is the typical lead time?
Prototype orders: 3-7 business days. Production orders: 10-20 business days depending on quantity and complexity. Rush orders are available upon request.

Q6: Can you handle secondary operations?
Yes. We offer bending, welding, stamping, CNC machining, powder coating, anodizing, electroplating, and assembly. All processes are managed in-house for consistent quality and faster delivery.

Q7: How do you ensure cut edge quality?
We use nitrogen assist gas for stainless steel and aluminum to achieve oxide-free, weld-ready edges. For carbon steel, oxygen assist gas provides faster cutting with acceptable edge quality for most applications.

Q8: Do you provide material certificates?
Yes. We provide material test certificates (MTC) for all orders, including chemical composition and mechanical properties. Third-party inspection (SGS, BV) is available upon request.
