TPX Resin Extruder
TPX® resin (trade name/ generic name polymethylpentene of Mitsui Chemicals, Inc.) is a polyolefin resin with excellent heat resistance, mold releasability, and transparency.
At rubber hose manufacturing sites, taking advantage of its features, it is used as a substitute for lead in many companies and manufacturing sites for sheaths during vulcanization and for mandrel due to recyclability.
Mitsuba Manufacturing Co. Ltd. has been manufacturing and selling dedicated extruders since the launch of TPX® resin. This time we Mitsuba have developed a new type that has been upgraded.
1. Low temperature high discharge extrusion
The new extruder adopts a special shape for the groove and screw of the feed liner to prevent the viscosity of the resin from decreasing due to shear heat generation, and the specific extrusion amount from decreasing even in the screw high rotation range, and to make it possible to correspond to a stable discharge rate with the rotation speed.
So new type superior discharge amount than conventional one at same screw revolution and concerning about capable of using in high revolution area, it is able to fill up traditional extrusion amount by means of extruder 1 or 2 sizes smaller than conventional type. And also, it became possible increasing recycle life-span by extruding in low temperature area.
2. Space saving and reduction of material loss
From the above section, the new extruder is an extruder with a smaller screw diameter and L / D than the conventional type, and it can supplement the required discharge amount, which leads to space saving.
In addition, the smaller size reduces the amount of residual material in the cylinder, which contributes to the reduction of material costs.
※50% reduction in residual material in the cylinder
3. Abundant size variations
The new extruder has a screw diameter of φ50 mm to φ150 mm, so you can choose according to the required extrusion amount.
