Consultation
Our sales representatives
will note your required
specifications, budget, andschedule. Feel free to specify
your requirements down to
the tiniest detail: e.g., “Assmall as possible,” or “Easyto install (in your product).” This will enable us to offer a more
optimal proposal.

At our Environmental
Testing Center at KEL
Headquarters, to verify
product performance, weconduct electromagnetic
field analysis with Ansys
HFSS and Dassault CST,
run thermal shock tests to examine deformation under changing
temperatures, and perform gas corrosion testing to verify platingdurability. Before beginning mass production, the specifications
are checked by the Quality Assurance Department.

Mass Production & Quality Control

Pressing & Plating (Contacts)
In the pressing stage, thin coiled copper alloy sheet is cut, bent,
and forged with dies to form contact terminals. The terminals
are then coated with highly precise gold plating in the necessary
areas with proprietary KEL plating equipment and jigs.

Molding (Insulators)
Our molding machines range in tonnage from 18 to
80 tonnes, allowing the production of everything fromnarrow-pitch to large insulators. To save energy, bothfully motorized and hybrid machinery are used.
