We will prototype from a minimum of one piece of stainless steel material.

We respond to all needs for stainless steel processing with reliable technology. Our diverse delivery record, from general materials to special steel, is proof of our trustworthiness.

Stainless steel, known for its excellent corrosion resistance and strength, is an essential material in various scenes of the industrial world. At Shinwa Koki, we handle a wide variety of stainless steel materials, including the easily machinable SUS303, as well as the more challenging SUS304 and SUS316, which are known for their high toughness, and even heat-treated steel. We are well-versed in the specific quality requirements of various industries, such as food machinery, semiconductor manufacturing equipment, and vacuum equipment, ensuring optimal processing tailored to each product. We deliver stable quality from small quantities of diverse varieties.
