We are good at precision press and deep drawing work and will accept any order from small to large lot.

 We will accept any order, from small to large lot based on the press and machining technology we have inherited for the past 64 years and our thorough quality control.
 Our in-house equipment includes mechanical and hydraulic presses (35 t and 150 t), and we can accept any order from small object press to deep drawing.
 For mechanical processing, we can handle complicated shapes using our 5-axis composite fabrication machine that has been recently introduced.
 In addition, we are expanding into design and manufacturing of “ozone water production equipment” for semiconductor. We are good at order-made production that meets your needs, so please feel free to consult us.
 We are looking forward to hearing from you.
