Polyurethane Ribbon Cast casting machine System for Roller Manufacturing without the Mold tools

Latest state-of-the art polyurethane casting machine for industrial rollers

Machines used for manufacturing both small and large rollers using polyurethane. A ribbon of liquid urethane is applied to a rotating roller and moved across the cylindrical surface. The method is somewhat similar to turning, but the material is applied instead of being removed. It is possible to build layers to different thicknesses for subsequent machining to accurate dimensions.

1. How to Work with Raw Materials

1-1 Preparing Raw Materials

(1) Pre-heat the polythene substrate and curing agent drum in an electric oven.

(2) The heating temperature is 45℃ for 10 hours preheating.

(3) It's a good idea to preheat the hardener drum by rotating it.

(3) It should be aged at room temperature for at least a week to achieve optimal properties.

(2) It usually takes about a week to cure at room temperature.

If this is not possible, tilt it slightly so that the hot air can be distributed evenly.

(4) Since the curing agent contains various amines, it should be stirred thoroughly after

into the tank to ensure even dispersion.
