Electromechanical Universal Testing Machine suitable to test Rod,
Wood, Concrete & Wood composites
I. Project Introduction:
Domestic microcomputer control electronic universal testing machine
started in the early 1990s, in order to improve the technical level
of enterprise products, the company has introduced foreign advanced
technology, so that the company's product technology level jumped
to a new level.
II. Application field:
The product is widely used in tensile, compression, bending and
shearing tests of metal and nonmetal materials. With a variety of
accessories, it can also be used for the mechanical properties of
profiles and components. In the test field of rope, tape, wire,
rubber, plastic and other materials with large deformation and fast
test speed, it also has a very wide application prospect. Suitable
for quality supervision, teaching and research, aerospace, iron and
steel metallurgy, automobile, construction materials and other test
fields.
Ⅲ. According to standards:
Meet the requirements of the national standard GB/T228-2002 "Metal
Materials tensile test Method at Room temperature", GB/T7314-1987
"Metal Compression test Method", in line with GB, ISO, ASTM, DIN
and other standards of data processing. Can meet the requirements
of users and provide the standard.
