Offering high flexibility in manufacturing technologies, Dowin enables professional robot-controlled processing on materials with its various features. To achieve this highly customized functionality, Dowin uses easily interchangeable multi-process heads and fiber laser sources. Compact and easily attachable/detachable adapters, developed separately for each processing head, allow different lasers to be used within the same facility on a single robot system without requiring extensive adjustments.
In particular, for parts requiring welding and surface processing with free-form and 3D surfaces, multi-axis robots provide unmatched solutions. Ensuring high production output and low defect rates for enhanced efficiency, Dowin delivers an improved operating method as a software-controlled fully automatic laser welding technology in mass production.
In the fields of mold repair, on-site welding of large workpieces, and high-precision manufacturing, flexibility, accuracy, and reliability are indispensable. The QCW-1.6M Telescopic Arm Mold Welding Machine is born to meet these challenges. It is more than just a piece of equipment; it is a mobile laser welding workstation integrating exceptional mobility, top-tier welding precision, and multi-functionality.
1. Exceptional Mobility & Coverage
1.6-Meter Super-Long Telescopic Arm: Acts as the welder's "mechanical extension," providing unparalleled operational freedom. It easily reaches deep, side, and complex-angle welds on large workpieces without repeatedly moving the heavy part.
Designed for On-Site Welding of Large Workpieces: Perfectly suited for the on-site repair and maintenance of massive, hard-to-move workpieces like large injection molds, die-casting molds, and automotive panel stamping dies, delivering a professional welding workshop right to the equipment.
Extremely Compact, Travels with Your Vehicle: The arm folds down completely, resulting in an ultra-compact footprint. It can even fit into a standard car trunk, enabling true "mobile service." This allows for rapid response to customer sites or outdoor emergency welding needs, significantly boosting service efficiency and competitiveness.
2. Top-Tier Welding Precision & Quality
Equipped with an Advanced QCW Laser Source: Leverages the advantages of Quasi-Continuous Wave pulse technology for precise energy output control.
Dual-Mode Functionality: Pulse (Spot) & Continuous Welding in One Machine: One machine combines two core processes. Pulse mode is ideal for precision spot welding, crack repair, and fine edge buildup with minimal heat-affected zone. Continuous mode enables high-speed, smooth, and high-strength continuous welding for long seams.
Combines Traditional Strengths: Successfully integrates the excellent precision control of traditional YAG lasers with the high efficiency of CW fiber lasers, achieving the highest level of welding precision and controllability in its class.
3. Multi-Process Adaptability
Versatile Machine for Complex Demands: Beyond mold repair, it excels at precision welding and repair welding of materials like stainless steel, carbon steel, and aluminum alloys. Its precise energy control minimizes workpiece deformation, reducing post-processing costs.
The QCW-1.6M is not just a tool; it is a key solution for industry pain points:
Scenario: Large molds experience wear, cracks, or manufacturing defects, requiring in-situ repair on the assembly line or at the customer's factory to avoid the high costs and delays of disassembly.
Solution: Utilizes the arm's reach and the machine's ultra-high precision to perform targeted welding repairs directly on the mold, restoring dimensional accuracy and surface condition, extending mold life.
Precision Cavity/Texture Surface Repair: Uses low-power pulse spot welding to fill defect points (e.g., pinholes, eroded spots) precisely point-by-point. Minimal HAZ preserves surrounding textures; only local hand polishing is needed.
High-Hardness Mold Steel (e.g., SKD61, H13) Cutting Edge Repair: Employs matching high-hardness powder or wire for multi-layer precision buildup via pulse or micro-continuous welding. Ultra-low heat input prevents base material hardness loss; post-weld air cooling achieves high hardness, followed by low-temperature tempering.
Deep Cavity/Narrow Groove Bottom Repair in Large Molds: Combines the 1.6m arm and coaxial observation system to position the laser head accurately into deep cavities. The non-contact, fiber-delivered laser completes bottom welding easily—a task difficult or impossible with traditional methods.
Scenario: Repair of automotive panel stamping die cutting edges, on-site adjustment/strengthening of large fixtures, rapid prototyping and repair of racing/special vehicle parts.
Solution: Mobility to the production line or repair shop for fine welding, ensuring strength and finish while minimizing impact on production rhythm.
