1
Chemical And Spectroscopic Analysis
Testing the products chemical from Raw Material, Before Heat Treatment, After Heatment, then can control the standard chemical products, depend upon the measurement of the wavelength and the intensity of electromagnetic radiation.
2
Tensile Strength Testing Mechine
We This tensile machines can testing the fasteners Tensile Strength, Yield Strength, Elogation, Contraction, Proof Loading.
Used to determine the strength and deformation behavior of a material up to the point of fracture.
3
Charpy Imapct Testing Machine
The working principle of charpy impact testing machine is: a pendulum of known energy is used to hit the sample supported by the horizontal beam, and the sample is destroyed by one impact of the pendulum.
1
Torque Measurement Machine
Torque Measurement Sensor is defined as a transducer for measuring torque and converts it into an electrical output signal.
Torque is a measure of the force that can cause an object to rotate about an axis.
2
Hardness Testing Machine
We have the Rockwell Hardness Testers, Vickers Hardness Testers, Brinell Hardness Testers.
The hardness tester measures the effect or depth of a localized enetration indentation made by a standardized indenter.
3
Salt Spray Testing Instrument
This is an accelerated environmental corrosion test in which metal specimens are exposed either continuously or intermittently to a fine mist of salt-water solution used to evaluate the resistance to corrosion of coatings
Measurement Testing
Measure the dimensions, shape and position tolerance, thread angle, major diameters、pitch diameters、minor diameters of the machinery parts, thread fasteners and special fastener products.
Testing Items:  Dimensions Measure; From and Position Tolerance Measure; Major Diameters、Pitch Diameters、Minor Diameters
