Rubber Plastic Composite Horse tube Line

This equipment is a line that produces hoses that combine synthetic rubber and fluororesin.
Taking advantage of our strength of being able to manufacture both rubber extruders and plastic extruders, we have various line-ups such as a line with a mandrel like this equipment and a line that extrudes rubber and plastic at the same time.
Our fluororesin extruder uses an extruder's material with excellent corrosion resistance.
