Lub raj seamless yog tsim los siv cov txheej txheem hu ua "extrusion". Thaum lub sij hawm tus txheej txheem no ib tug khoom steel bar yog pierced txawm lub chaw uas siv ib tug tuag, tig cov khoom puag ncig mus rau hauv ib puag ncig raj.
Yeej muaj ob hom seamless raj:
Cold Drawn Seamless (CDS) ib txwm ua los ntawm SAE 1018, muaj qhov ua siab ntev thiab zoo nto
Kub Finished Seamless (HFS) ib txwm ua los ntawm SAE 1026, muaj kev tiv thaiv tsawg dua thiab ua kom tiav - Tsis muaj zog li CDS
