There are plenty of testing machines in our company.
Tensile testing machine which can test tensile strength & elongation @ break according to GB/T 1040.2/1B-2012
abrasion testing machine which can test friction coefficient & abrasion loss according to GB/T3960-1983(1989)
Density balance can test material density to assure the material quality and homogeneous distribution
Shore hardness (D) meter
We also develop the testing machines by our team workers. For example: blow-off testing machine, fatigue testing machine and friction testing machine.
Main OD / Lip OD / Lip length
Imprint depth of the PTFE composite material in the grooves
Resistance against wear and blow-off of the PTFE part at high velocities
XIAYI is a professional company which produces different size and design for shock absorber pistons.
XIAYI has a complete set of testing equipment which can control the quality for the material.
