DN Series Customized Automatic Resistance Spot Welding Machine for Door Hinge 

The DN Series Customized Automatic Resistance Spot Welding Machine for Door Hinge is a specialized, high-performance welding system engineered specifically for the efficient and precise manufacturing of automotive and industrial door hinge assemblies. Available in power configurations from 25KVA to 150KVA, this fully integrated automatic hinge welding system combines robust DN Series welding technology with custom-tailored automation to deliver consistent, high-strength welds at optimal production speeds. Designed to meet the stringent requirements of door hinge production, this system ensures perfect alignment, repeatable quality, and maximum throughput for competitive manufacturing operations.

Product Overview:

The DN Series Automatic Door Hinge Welding System is a turnkey production cell built upon the proven reliability of the DN Series resistance welding platform, enhanced with custom automation for hinge manufacturing. The system automates the complete welding sequence: precise loading of hinge components into custom fixtures, accurate positioning under the welding electrodes, execution of programmed spot welds, and controlled discharge of finished assemblies. Utilizing precision actuators or optional robotic positioning, the system guarantees each weld is placed accurately according to hinge design specifications. Governed by the SUN18B Intelligent Microprocessor Controller, the entire process—from motion coordination to weld parameter execution—is seamlessly integrated to produce flawless, consistent hinge assemblies.

Machine Structure & Key Components:

• Robust DN Series Welded Steel Frame – Inherits the heavy-duty, vibration-resistant construction of the standard DN Series, providing a stable foundation for precision automation.
• Application-Specific Hinge Fixturing – Custom-engineered fixtures and clamps designed for specific hinge components, ensuring zero-defect positioning and repeatability for each welding cycle.
• Automated Component Handling System – Configurable options include pneumatic pick-and-place, linear conveyors, or robotic arms for consistent part loading and unloading.
• Precision Welding Head Positioning Unit – Dedicated 2 or 3-axis servo or pneumatic positioning system for moving the welding gun accurately to each programmed weld location on the hinge.
• High-Capacity DN Series Welding Transformer – 380V input (single or three-phase based on model), 50% duty cycle rated for continuous, high-volume production environments.
• SUN18B Intelligent Welding Controller with Automation Interface – Advanced controller specifically programmed for automated hinge welding sequences. Manages dual current/time settings, coordinates with the positioning system, and provides real-time process monitoring.
• Custom-Designed Welding Electrodes & Guns – Electrodes and gun arms are tailored to the hinge geometry, ensuring optimal current flow, access, and extended service life.
• Integrated Safety System – Full perimeter guarding with safety interlocks, light curtains, and an emergency stop system for complete operator protection.
• Production Monitoring Package (Optional) – Weld process monitors, data loggers, and SPC (Statistical Process Control) software for quality traceability and process optimization.

Key Features & Advantages:

• Proven DN Series Reliability with Custom Automation – Leverages the ruggedness and performance of the standard DN Series welder, enhanced with purpose-built automation for hinge production.
• SUN18B Controller for Automated Sequences – Microprocessor system executes complex welding schedules (dual pulse, upslope) while synchronizing with the automated positioning and handling systems.
• Turnkey Hinge Production Solution – Delivered as a complete, ready-to-operate cell, significantly reducing integration time and ensuring optimal performance from day one.
• High Precision & Repeatability – Custom fixtures and precise positioning achieve weld location repeatability within ±0.2mm, guaranteeing consistent hinge geometry.
• Optimized for High Volume – Automated cycling and efficient weld sequencing minimize non-weld time, achieving typical cycle times of 10-30 seconds per hinge assembly.
• Consistent, High-Quality Welds – Automated process eliminates operator variability. The SUN18B's constant current control and phase shift regulation (1%-99%) ensure each weld nugget is identical.
• Flexible & Future-Proof Design – Modular design allows for re-fixturing or reprogramming to accommodate future hinge design changes or new product introductions.
• Reduced Operational Costs – Minimizes labor, scrap, and rework while maximizing equipment uptime and energy efficiency.
