Advanced Solution for the Low-Voltage Electrical Manufacturing Chain
Low-voltage electrical manufacturing is advancing toward smart, high-precision, and high-volume production. As a pioneer in resistance welding solutions, Heron solves critical challenges in silver contact welding machine assemblies, circuit breaker, frame breaker and relay terminals. Our systems provide a fully traceable, intelligent and data-driven process, ensuring every connection meets the good use performance of electrical components.
INDUSTRY PAIN POINTS
Four Overarching Joining Challenges
Low-voltage electrical manufacturing demands extreme precision and reliability. Traditional welding methods struggle to meet the quality and throughput requirements of modern production lines for circuit breakers, relays, and silver contact assemblies.
01
High Precision Requirements
The contacts, coils and copper braided wire require extremely high accuracy (usually within ± 0.01mm) and no splash and deformation.
02
Welding Reliability Risk
Like silver contacts and tripping elements inside the circuit breaker, the traditional welding has large heat input, which is easy to cause thermal damage or deformation.
03
Low Efficiency and Unstable Quality
Manual welding has a lower production capacity, which is difficult to cope with large-scale production. It relies on workers’ experience, resulting in increased costs.
04
High Maintenance Cost
Electrode wear compromises weld quality, appearance, and strength. Frequent cleaning, dressing, and replacement drive up both production and downtime costs.
