Technical Performance & Characteristics

1.Advanced online fault detection, hardening, continuous overall tempering and ball blast techniques are incorporated so that mechanical strength and overall performance are enhanced.

2.Threads are processed on special numeral control lathes avoiding any rotation of the rod and then subject to roll forming so as to ensure high precision, reliable performance and extended service life.
