The development of sophisticated methods for internally oxidizing silver tin alloys to form a wide array of silver metal oxide compositions and microstructures.

The development of machines for producing bimetal rivets from silver and copper alloys economically, allowing more efficient use of silver. Fourth generation machines now are capable of near 100% bonds between silver contact and copper base metal.

A highly automated manufacturing operation for production of contact and contact sub-assemblies. Different techniques, such as welding, sticking, brazing, and cladding, are used in sub-assemblies, and an automation ensures efficiency and product consistency. Electronic eyes and transducers are employed in the processes to monitor quality, mistake proofing and achieve zero defects in our finished product.

Chugai’s new double spinning process keeps almost perfect sticking bound between contact and base metal.

Chugai develops a set of special inspection fixtures and instruments to monitor, control, and measure the spring force at specific angles, and do other dimension measurements.

In addition, freon-free automatic ultrasonic cleaning process prevents the contact surface from contamination.

Chugai engineering staff is knowledgeable in contact materials, contact manufacturing, contact design, contact application, and contact failure analysis. Our advanced contact technology and engineering assistance will insure that you obtain the best value for your application requirements and your precious metal contact expenditures.
