From billet to packed set
Four operations run under one roof — forging, machining, inspection and packing.
Step 01
Forging
Heated steel bar is pressed into socket blanks, setting the wall thickness and grain structure.
Step 02
CNC machining
30 lathes and 10 machining centres turn the hex profile, drive end and chamfer to tolerance.
Step 03
Inspection
Dimensions, hardness and torque are checked on a sampling plan before plating is signed off.
Step 04
Packing
Sets are assembled into blow-mould cases, labelled for your market and cartoned for export.
