〔Main equipment〕 5 universal testing machines/7 servohydraulic fatigue testing machines/1 SEMEDX/1 impact testing machine/８ hardness testing machines/11 microscopes

We conduct a wide variety of tests in accordance with purposes of testing in compliance with both domestic and international specifications or standards .We provide accurate data by using testing methods with high objectivity. In addition, we’re willing to invest on state of the art machinery and equipment such as fatigue testing machines.

Training of engineers able to provide suitable advice to our customers. Some of our staff are on loan to Independent Administrative Institution NIMS (National Institute for Material Science) and give technical support in the development of super heat resistant material. We are deepening technology exchanges with world-leading research institutes and companies for materials while fostering engineers as a way to offer our customers useful suggestions as well as data.

【The estimation of fracture-mechanical parameters】

K1c test ,J1c test and Crack growth test: These tests based on a damage tolerant design are for obtaining fracture-mechanical parameters which are indispensable to design constructions(such as building, aircrafts ,automobiles ).We conduct excellent test control by using cutting-edge equipment and also support safety designs.

【The estimation of fatigue life】

Thermomechanical fatigue testing, High temperature low cycle testing and High temperature high cycle testing: Super heat resistant material used for jet engines, gas turbines or combustion chambers of car engines need a test which simulates status of use. We conduct tests with much objectivity and contribute to the reliability assessment of testing.

【Tensile Testing】

Tensile testing is a representative method of examining mechanical characteristics of metallic materials. Although materials rupture when strain increases, before they rupture the maximum tensile strain which appears on materials or which materials can endure are examined.

【Creep Rupture Testing Machine】
The creep rupture testing machine mea-sures changes which occur with time,and especially is used to test materials which are used at a high temperature for a prolonged time.

【Hardness test】

Hardness test is relatively easy to conduct. Generally, we can predict the tensile strength of a specimen by measuring its hardness. For other purposes, this test is used also for managing the results of heat-treated copper products.

【Impact Testing】

In this test, energy and toughness required for fracture are evaluated by breaking a rectangular- cylindrical notched specimen by applying impact at high speed.

【Corrosion Testing】

In this test, a test specimen is corroded with hydrochloric acid, and then patterns or pits which appear on the surface are examined macroscopically.
