Strong R&D team
Responsible staffs
Clean workshop
We will bring you pistons with good quality and competitive price.
Applications:
Car or motorbike shock absorbers
Competitive Advantage:
XIAYI can produce bands rings to low down the cost and control the quality at home, at the same time we
can design and produce automatic banding machine and non-standard testing machine, can test drawing
force testing and oil immersion testing.
