HDMI cable manufacturing process 

Conductors bunching → Conductors Insulating → Pair twisting + Alu foil shielding → General twisting + Alu foil / Mylar shielding → Braiding shielding → Outer jacket sheathing



Equipment required to produce HDMI cable

TZ-BM500 double twist bunching machine  For Conductor bunching.

TZ-ET30+65 physical foaming extrusion line → For Conductors insulating of foam-PE (skin-foam).

TZ-EP50 PVC extruder machine production line → For Conductors insulating of PP / PVC.

TZ-SC500 cantilever single twisting machine → For Pair twisting+Alu foil shielding (tapping).

TZ-SC630 cantilever single twisting machine → For General twisting+Alu foil / Mylar shielding (tapping).

16 courier braiding machine → For Braiding Shielding of tinned copper wire.

TZ-EP70 PVC extruder machine production line → For Outer jacket sheathing of PVC.

16 courier braiding machine → For Outer braiding of Nylon wire (optional).
