Core Technology & Products

Medium Frequency Spot and Projection Welder (ADB Series)

This flagship product line achieves unprecedented precision control with inverter frequencies reaching 1000Hz, providing current control accuracy 20 times higher than traditional AC welding machines. The 3-phase balanced power design reduces power grid demand by one-third compared to conventional systems while maintaining a power factor of 0.7-0.9. The HMI interface provides real-time monitoring of current and timing parameters with integrated pressure and water flow alarms, ensuring consistent nugget size and minimal spatter even when processing high-strength steels and sensitive materials.

Capacitor Discharge Spot Projection Welding Machine (ADR Series)

Engineered specifically for heat-sensitive components, this series delivers discharging times of approximately 10 milliseconds, preventing surface discoloration and thermal deformation. The system maintains energy fluctuation within 1% regardless of power grid instability, with capacity reaching up to 200KJ for extremely large parts. Infrastructure requirements are reduced to less than one-fifth the power capacity of AC welders, making it ideal for multi-point projection welding applications.

Flash Butt Welding Machine (AUNS/AUVS Series)

Specialized for large-section metal parts and special steel alloys, this equipment achieves weld quality nearly identical to base metal for sections up to 20,000mm². The AUBS-630*2 New Energy Electric Axle Double-Head Pulsation Flash Butt Welder represents a breakthrough as the first domestically developed double-head flash butt welding machine for truck axles, recognized with the "First Set of Major Technical Equipment" certification in 2024.

Automation & Industry-Specific Systems

Agera’s fully automated workstations include automobile nut and bolt projection welding workstations with robot integration, new energy vehicle threshold beam robot workstations, shock absorber automatic welding lines, and hydrogen production bipolar plate fully automatic welding lines. These systems integrate seamlessly into existing production workflows across automotive components, sheet metal fabrication, electrical electronics, and emerging energy sectors.

Technical Differentiation

The company’s proprietary medium-frequency welding controller, independently developed in 2015, broke the technological monopoly previously held by imported controllers. With 50+ invention and utility model patents and multiple computer software copyright registrations, Agera operates the Suzhou Intelligent Pulse Flash Butt Welding Control Engineering Technology Research Center and maintains strategic cooperation with the China-Ukraine Welding Research Institute.

Agera’s solutions serve diverse sectors including automotive manufacturing (high-strength steel, nut projection, axle welding), electronic and electrical (fine electronics, copper wire, silver contact welding), household appliances (microwave ovens, compressors, refrigeration casing), hardware and tools (storage racks, lifting tables, steel drums), new energy (hydrogen bipolar plates, EV battery busbars), and aerospace and military applications requiring high-precision specialized welding.

Quantifiable Customer Results

In truck axle manufacturing, Agera’s first domestic double-head flash butt welding machine substantially improved efficiency for heavy-duty vehicle production lines. For the pipe pile industry, the ARH-IDB-202 Automatic Welding Line achieved "First Set" major equipment recognition for its technical breakthrough in end plate flange welding automation. Automotive safety applications implementing robot-integrated nut projection welding for anti-collision beams and subframes report 100% weld reliability in safety-critical parts. In EV component production, automated 90mm² wire harness square forming and welding systems support high-power electric vehicle systems for leading manufacturers including BYD and Great Wall Motors.

Global Presence & Service Scale

Since its establishment in 2012, preceded by a Shanghai trading company founded in 2004, Agera has expanded its footprint across domestic China, Europe, Southeast Asia, the Middle East, South America, and North America. The company has served 6,000+ customers with its accumulated 80,000+ welding workpiece cases.

Conclusion & Selection Recommendations

The resistance welding equipment landscape offers diverse technological approaches tailored to specific manufacturing requirements. When evaluating potential suppliers, manufacturing decision-makers should prioritize three fundamental considerations: first, assess whether the supplier’s core technology directly addresses your specific material combinations and production volume requirements; second, verify the depth of application experience within your industry through documented case studies and quantifiable performance metrics; and third, evaluate the comprehensiveness of technical support infrastructure, including process consulting capabilities, system integration expertise, and responsive after-sales service networks.

The optimal equipment selection depends on careful alignment between your production challenges and supplier capabilities rather than brand recognition alone. Conducting thorough process trials and requesting detailed technical documentation will ensure long-term manufacturing success and return on capital investment.
