ddl series electronic universal testing machines are cooperative products of doli company in germany and our company. ddl series and dns series testing machine have the same mainframe construction. the only different is that ddl series adopt edc digital controller made in doli, while dns series adopt knz controller made in our company. three closed-loop pid control for force, deformation and displacement can be realized and switched smoothly.
main uses
this series testing machines are mainly used for mechanical performance tests for metallic, non-metallic and composite materials, such as, tensile, compression, bending, shearing, peeling, tearing tests and so on. through these tests, max. test force, tensile strength, bending strength, compression strength, elastic modulus, elongation, yield strength and other parameters can be obtained. this series testing machines are suitable to test mechanical properties of materials for mechanics lab and quality inspection departments.
