Thank you for visiting our website

Thanks to our company, more than 40 years have passed since its establishment, and we have gained wide trust as the only manufacturer in the manufacture and sale of sieves in Tokyo.
Tokyo Screen Co., Ltd. is a testing organization that meets the requirements of ISO / IEC 17025 international standards, has been accredited by a registered certification body, and is officially recognized as a testing organization that has the ability to provide technically appropriate test results. For JIS Z 8801-1 test sieves, it is possible to issue a calibration certificate with the ilac MRA symbol mark.
We manufacture and sell everything from conventional mesh screens to electroformed screens and screens using ultrasonic waves. We provide screens that meet customer needs with reliable technology.
We can also process stainless steel products. We have fulfilled our customers' requests as much as possible and manufactured various custom-made products.
We accept orders from the required size, so please feel free to contact us for an estimate, price, and delivery date. We have posted products that have been produced in the past on our website for customers who do not know the design in detail even though they are said to be stainless steel products.
Please see for reference.
