Environmental Quality Assurance
In recent years, regulations restricting environmentally hazardous substances in products have become increasingly stringent worldwide.
It is now essential to manage banned substances—such as those restricted by the EU RoHS Directive—and to provide transparent information regarding the chemical composition of products. Furthermore, strict compliance with various legal frameworks, including the REACH Regulation, is mandatory.
At Sanko, to minimize the environmental impact of chemical substances, we work closely with our suppliers to actively monitor and communicate data on the chemical substances contained in our parts and raw materials. This commitment applies not only to electrical and electronic equipment (EEE) and automotive products, but to any product upon customer request. Through these rigorous efforts, we ensure the delivery of safe and fully compliant products.

Inspection Machine List
PJ-H30 (Mitutoyo)
Projector (contour shape / dimension measuring instrument)
This is the device that projects the shadow that is created by irradiating light to object to be measured on the screen to measure the dimensions of object to be measured. This device can measure the point that cannot be measured by micrometer, etc.

SURFCOM-2800E (TOKYO SEIMITSU CO., LTD.)
Surface Texture and Contour Measuring Instruments
This shows Surface Texture and Contour Measuring Instruments (the surface-roughness and outline shape compound measuring instrument) that achieved advanced function (roughness, angle, and size) and excellent operativeness.

RONDCOM54DX (TOKYO SEIMITSU CO., LTD.)
Roundness measuring instrument
Roundness and coaxiality, etc. of object to be measured can be measured. The flatness can be also measured depending on the shape of object to be measured.

HM-211 (Mitutoyo)
Vickers hardness tester
Hardness is measured based on the size of the indentation formed when a diamond indenter is pressed into the test specimen with a specified test force.

HR-530(Mitsutoyo)
Rockwell hardness tester
The Rockwell hardness tester determines hardness by measuring the depth of the indentation formed by pressing an indenter into a test specimen.
(Various hardness tests can be performed by exchanging the types of indenters.)
