For extruders as well, we can offer optimal proposals that meet your needs, such as non-vent type, vent type, pin type, pin convert type, and gear pump combination type.
It is a method to open the sheet from the tube by making a cut in the product discharged from the cylindrical tube.
As a take-up method, there are a type that performs tubing in the horizontal direction and a type that performs tubing in the vertical direction.
The vertical tubing type does not generate weld lines, but compared to the horizontal tubing method, there is a tendency for the extrusion temperature to rise due to the higher pressure.
Although it is not suitable for many kinds of products, it is cheaper than other methods.
Since it is a cut-and-open method, Please be careful when high viscosity material sheets or thick sheets extrude, it warps In addition,
if the viscosity is low and the thickness is thin, the sheet will stretch, so the thickness is extruded in anticipation of this.
