layer” shapes the straight line product into circular convolutions, after which it is moved to a
convolution conveyor, producing “wire rod coil”.

Annealed wire

1) Intermediate drawing: Wire rod is transformed into smaller wire. TYCN has 13 drawing machines
for small size and 10 drawing machines for big size.

2) Spheroidized annealed: Wire from step 1 will be annealed through the spheroidized annealed
machines. Currently, TYCN has 11 bases machines.

3) Pickling & coating: Wire will be surface cleaned using one operating line and coated with the
rust proof solution as well as lubricants using one of 2 operating lines.

TYCN currently has 24 skin pass machines.

Screws & Bolt

1) Heading and threading: Wire will be delivered to the forming plant, passing through the heading
and threading machines.

2) Case hardens: After the forming process, screws are treated by carburization to improve their
mechanical strength.

3) Plating: Surface finishing and coating is necessary for screws and bolt to for rust-proofing and
improve their appearance. The surface treatment processes vary depending on customer
