Deep drawing of stainless steels
Gifu Seiki Kogyo is an expert about deep drawing of the stainless steel which is hard and difficult to process. process from trial to mass production by in-house press die.
It is said that stainless steel is difficult to process for its hardness and getting wrinkles.
We manufacture parts which need high precision like Temperature sensor, USB connector, cellphone hinge by the progressive press.
Some cases of deep drawing
We can process the above stainless steels with a thickness in the range from 0.05mm - 2mm
We can also handle the surface treatment of stainless steels processed
We perform surface treatments like barrel polishing, hairline finish, buffing after being pressed stainless steels
Materials except stainless steel that we can process
