High Discharge Type Resin Extruder

The special shape of the screw and cylinder makes it possible to extrude the same throughput as the conventional extruder even in the high rotation range which was suppressing the heat generation of the resin with the rotation range decreased due to the limitation of the resin temperature. It can be handled with a smaller extruder of 1 to 2 sizes down.
Machinery and electrical parts are basically parts that can be procured in Japan. So PLC with manufacturers that customers are accustomed to use can be utilized with confidence in maintenance even after delivery.
We also have a test machine, so you can check it if you have a request (in paid)

Product Features

High throughput / low temperature extrusion

The specific throughput at 100 rpm is 25% higher for PE materials and 35% higher for PVC materials than standard type extruders. (Compared to our company)
In addition, the effect of shear heat generation due to screw rotation is small, and since it could be used in the high rotation range, the total throughput can be expected to be nearly double.
Note) There are differences depending on the resin material, extrusion size, and extrusion pressure

Increase production speed

Within the limited installation space of the extruder, it has the same throughput as a large extruder of one size-up or more, which leads to an improvement in production speed.

Space saving and Material loss reduction.

Since the size of an extruder can be made smaller than before in 1 to 2 sizes down with the same throughput, the degree of freedom in the layout of the two-layer or three-layer extruders is created, and the joint part can be shortened, which leads to improved cleanability and resin burning. Also the amount of residual material in the cylinder when changing materials or colors is reduced, and the effect of improving running costs can be expected.

Abundant size variations

We have a variety of sizes with screw diameters from φ65 mm to φ150 mm, so we can propose any availability according to the throughput and application.
