Separate Water Cooling Jacket Feeder
longer and deeper rectangle grooves design with internal complex cooling cycling system, excellent cooling performance in feeding zone and higher output capacity.

Normal Water Cooling Jacket
The normal feeder water cooling jacket is very small.

Separate Water Cooling Jacket
The separate water cooling jacket feeder water cooling jacket is very big,
