Durability and Efficiency

for Exceptional Performance

The conical twin-hole barrel is characterized by a diameter that progressively narrows from the inlet to the outlet, forming what is known as the nominal diameter of the conical extruder.

The creation of this type of barrel presents a significant challenge: maintaining the correct distance and angle between the holes.

This is crucial since the barrel must not only have a conical shape but also precise alignment of the holes, making it one of the most complex to produce in its category.

Conical barrels can have a smooth or grooved external diameter, depending on the specific application. In the case of external grooves, they play a functional role beyond aesthetics, ideal for supporting the positioning of the cooling circuit tube, usually made of stainless steel or copper.
