Office Chair Back Tensile Testing Machine
Product use
This Office Chair Back Tensile Testing Machine is specially used to
test the tensile strength, fatigue resistance, structural stability
and durability of the backrest for office chairs, swivel chairs,
executive chairs and gaming chairs.
It applies a continuous and stable pulling force to the chair
backrest to simulate the backward leaning, pulling and impact
forces during actual use. The machine can accurately control the
test force, pulling speed, cycle times and stroke, and
automatically judge whether the backrest, backrest connection,
screws or base have cracks, deformation, looseness or damage.
Equipped with high-precision sensor and intelligent control system,
it ensures stable test process and accurate data. It is widely used
in furniture factories, quality inspection laboratories and
certification bodies to provide reliable test basis for product
safety, quality control and standard compliance.
