Product Introduction
The Seam Fatigue Tester is a 2-position desktop machine used to
evaluate the tear resistance or the elongation of seam pinholes of
textile or leather seat materials. Each testing position includes a
pair of corresponding fixtures for fixing the sample, and a height
gauge for setting the distance between each fixture clamp at 140mm.
The sample is placed on the clamping device, and the positions of
the left and right clamping devices are adjusted to ensure that the
test spacing complies with the standard requirements. The number of
test cycles is set, and the test begins. At this time, the reducer
drives the middle clamping device to perform reciprocating motion.
The left and right clamping devices are connected to a 3kg load,
and during the reciprocating motion of the middle clamping device,
the left and right samples respectively undergo a loading and
unloading process within one cycle. The proximity switch connected
to the counter records the movement cycle of the clamping device,
and the test stops when the set number of test cycles is reached.
The change at the seam of the seam area is measured to characterize
the material's seam fatigue resistance.
Scope of Application
This method is used to evaluate the fatigue resistance strength of
the seams on the surface materials of automotive seats. The surface
materials of automotive seats (such as leather, synthetic leather,
fabric, etc.) are mostly composed of stitched and bonded
structures. The stitching strength of the material seams and the
fatigue resistance strength of the seam openings directly affect
the service life of the seats. By testing the strength and lifespan
of the material seams, it is possible to effectively predict the
lifespan of the seats and provide improvement directions for
enhancing their lifespan.
Instrument features
The mechanical components are made of non-corrosive structural
aluminum and stainless steel materials;
Long-lasting powder coating and anodizing surface treatment;
Precise spherical and needle-shaped bearings;
Programmable controller with self-stop function;
Manual adjustment for test speed;
Adjustable height of the weight holder;
Adjustable spacing of the fixtures;
The openable protective cover can protect the operator's hands from
contact with the test bench, preventing potential dangers.
