Manufacturing Process
Our manufacturing process is specialized and optimized for Nickel alloys from melting to final products with a highly quality control system. High performance and highly reliable special metals such as shape memory alloys, electric resistance materials, thermocouple materials and heat-resistant materials for existing applications and new product developments are available. We can provide tailor-made products with fine-tuned support for your needs.

Melting & Casting
Ni-Ti and Ni alloys are melted and casted in a vacuum chamber due to avoid oxidation.

High Frequency Vacuum Induction Melting & Casting Furnace

Molten at casting
Hot rolling
The ingot is pre-heated and rolled down by hot reverse rolling and following hot tandem rolling.

Pre- heating furnace before hot rolling

Hot reverse rolling
Cold work ( cold drawing or rolling)
Cold drawing or cold rolling is performed, and then appropriately annealed to remove working strain.

Cold drawing

Continuous annealing furnace (RA: Running Annealing)
Other process
Spring forming and centerless ground process are by outsourcing.
