Spring Coiling - Cutting-edge winding machines produce coil springs with maximum strength.
Surface compression - Shot peened in order to compress the surface and extend the lifetime of the springs.
This process is essential for the durability of lightweight springs and heavily stressed springs.
Surface coating - Equipped with a zinc phosphate coating to preserve the epoxy powder coating.
The zinc-phosphate coating also prevents the spring from corroding.
Labeling and packaging - Glued label attached to the spring with an arrow indicating the installation direction. Many springs have similar ending coils, but there is only one correct installation direction.
