Since our establishment in July 2004, we have dedicated ourselves to structural and engineering innovations within the industrial laser landscape. Spanning a dedicated 500 square meters of high-tech office and R&D space, coupled with a massive 32,000 square meter factory floor, our machinery represents the pinnacle of modern manufacturing. All equipment passes strict quality parameters and complies with European Union CE authentication, American FDA certificate, and ISO 9001 guidelines.
With DH series lasers, we deliver an structural solution addressing mechanical deflection and optical energy loss. Combining robust fiber optics from world-class laser source manufacturers (like Raycus and IPG) with automated nesting systems, these machines achieve rapid processing speeds with narrow kerf widths, eliminating secondary deburring processes for most structural metals.

Core Architectural Advancements of the DH Series

Thermal Distortion Prevention

Utilizing high-temperature annealing procedures on fully welded heavy-duty steel beds ensures structural rigidity over decades of intensive operation, resisting vibration and alignment shifts.

Dual Intelligent Exchange Tables

Reduces sheet loading/unloading cycle times from minutes to mere seconds. High-efficiency hydraulic positioning locks the working tables dynamically for repeatable tolerances.

Advanced Direct Gas Drive

Features state-of-the-art oxygen, nitrogen, and compressed-air proportional valve controls. Optimizes cutting edge quality based on real-time thickness tracking algorithms.

Helping World Metal Cutting

Why Global Enterprises Partner with China's Premier DH Series Factories

Unmatched supply chain integration, raw manufacturing scale, and high-performance optical engineering.

In the global laser system market, domestic manufacturers are no longer chosen solely on cost differentials. Today, the choice of a Chinese facility for the DH series production represents a strategic technological partnership. By utilizing extensive domestic supply chains, our factory coordinates engineering efforts directly with laser source research centers, electronic automation suppliers, and precision rail developers.

Full Supply Chain Clustering

Proximity to structural casting foundries and precision component manufacturers dramatically reduces assembly times, allowing us to build, calibrate, and ship large-format laser cutters faster than competitors.

Agile OEM & ODM Customization

We provide OEM and ODM manufacturing services for over 30 leading global brands. Our machinery layouts are tailored to meet unique voltage standards, footprint limitations, and specific cutting software requirements.

Cost-Effectiveness at Scale

High-volume manufacturing processes combined with standard components allow us to lower unit production costs, passing substantial capital savings back to procurement directors.

Industry Trends: The Next Wave of Sheet Metal Processing

Smart automation, Ultra-High power laser arrays, and clean processing systems shaping the next decade.

The global fabrication industry is moving quickly towards fully automated systems. The integration of high-power resonators (ranging from 10KW to 30KW) has turned laser cutting from a thermal separation process into a highly cost-efficient production method.

Ultra-High Power Output

The standard DH series now includes 12KW to 30KW platforms, enabling clean cuts through thick plates (stainless steel up to 80mm and carbon steel up to 60mm) with nitrogen assist.

Robotic Integration & AI

Future operations rely on material loading, sheet sorting, and transport systems handled by robotic gantries and autonomous guided vehicles (AGVs), minimizing operator safety risks.

Reduced Environmental Impact

Industrial dust extractors with high-efficiency particulate air (HEPA) filters capture up to 99.9% of metal vapors during operation, meeting modern corporate sustainability objectives.

Localized Scenarios & Industrial Applications

How the DH series matches processing demands across diverse sectors, from heavy automotive assembly to delicate food-grade kitchenware.

About Products

Aerospace & Automotive

Cutting critical bracket components and panels with high geometric repeatability. Real-time capacitive sensors keep the cutting nozzle at a constant distance from the metal sheet, avoiding material collision.

Structural Sheet Metal & Cabinets

Processing standard enclosure designs, structural cabinets, and server racks. Fast processing profiles and integrated nesting software maximize material yield.

Kitchenware & Packaging

Ensuring clean cut edges on stainless steel alloys (304, 316) without chemical scaling or dynamic thermal distortion, meeting rigorous sanitary standards.

Global Procurement Checklist

Global procurement managers evaluating fiber laser systems must assess more than just the capital purchase price. The checklist below highlights key parameters to verify with a manufacturer:

  • Optical Integrity: The quality of the laser source (Raycus, MAX, IPG) and the cutting head optics (Raytools, Precitec).
  • Mechanical Rigidity: Total machine weight and structural bed configuration (cast-iron vs. heavy plate-welded frame).
  • Gas Assist Efficiency: Real-time software adjustments for gas consumption to keep operational costs low.
  • Compliance & Certifications: Official documentation showing compliance with CE, FDA, and ISO 9001 standards.
  • Post-Sales SLA: Regional technician availability, online diagnostic connectivity, and spare part replacement turnaround.

Technical Q&A: In-Depth Fabrication Insights

Expert answers addressing the design, purchase, and operation of DH series machinery.

Q1: What are the main design differences between the DH series and basic fiber laser models?
The DH series features a reinforced machine bed designed to handle high-power dynamics. Its heavy frame goes through high-temperature thermal treatment to relieve internal stresses, preventing mechanical distortion during high-acceleration cycles. It also includes an integrated exchange table system for fast material handling.
Q2: How does the integrated tube rotary axis benefit a sheet metal shop?
Models like the LX3015FT combine sheet and tube cutting capabilities in a single workspace. This design saves floor space compared to operating two separate machines and allows shop owners to quickly switch production from flat sheets to round, square, or rectangular tubing using a single laser source.
Q3: What are the maintenance protocols for a high-power fiber laser cutting head?
Maintenance focuses on keeping the optical path clean. This requires regular inspection and replacement of the protective windows, ensuring the nozzle is properly aligned and calibrated, and keeping the gas supply lines free of moisture or oil. Modern DH series machines feature monitoring systems that alert operators before a component reaches its wear limit.
Q4: Can these systems cut highly reflective metals like brass, copper, and aluminum?
Yes. Modern fiber lasers operating at 1.06-micron wavelengths are well-suited for processing reflective metals. Higher power levels (3KW and above) combined with nitrogen or oxygen cutting gas assist ensure clean separation without damaging the laser source from back-reflections.
Q5: How does the WE67K bending machine complement DH series laser cutting machines?
The WE67K electro-hydraulic servo bending machine provides the precision formatting needed after laser cutting. Using high-resolution CNC controllers, it coordinates hydraulic cylinder positioning to produce accurate bends, maintaining consistency between flat-cut patterns and finished structural components.
