Multi-component Cast Elastomer Polyurethane Machines (MDI/TDI) For PU Wire Guide Rollers
SCPU-204 type high temperature elastomer casting machine is newly developed by our company based on learning and absorbing advanced techniques abroad, which is widely employed in the production of wheel, rubber covered roller, sieve, impeller, OA machine, skating wheel, buffer, etc. This machine has high repeat injection precision, even mixing, stable performance, easy operation, and high production efficiency, etc.
1. For sandwich type material bucket, it has good heat preservation
2. The adoption of PLC touch screen human-computer interface control panel makes the machine easy to use and the operating situation was absolutely clear.
3. Head fixing controlled directly by PLC operating system,easy of operation.
4. The adoption of new type mixing head makes the mixing even, with the characteristic of low noise, sturdy and durable.
5. High precision pump lead to measuring accurately.
6. Easy for maintenance, operation and repair.
7. Low energy consumption.
Pour head:
Adopting high speed cutting propeller V TYPE mixing head (drive mode: V belt), ensure even mixing within the required pouring amount and mixing ratio range. Motor speed increased through a synchronous wheel speed, making the mixing head rotate with high speed in mixing cavity. A, B solution are switched to casting state by their respective conversion valve, come into the mixing champer through orifice. When the mixing head was at high speed rotation, it should be equipped with reliable sealing device to avoid pouring material and ensure the normal operation of the bearing.
Electrical apparatus control system:
Composed of power switch, air switch, AC contactor and the entire power, heating control elements circuit like heating and others. Accomplish equipment operation together with PLC (pouring time and automatic cleaning), so as to ensure its well running. PLC equipped with ultra high pressure alarm to protect metering pump and material tube in material system from damage. Also withting of temperature upper and low limits to insure materials’ normal operation under stable temperature. Temperature error of ± 2 ℃.

Polyurethane products are used in a wide variety of applications and industries. While a large part of our focus is on bulk material handling, concrete and agriculture, we can do so much more.
Other industries that we have had success in are microelectronics and photovoltaic industries, where our wire-cutting rollers are used in the creation of silicon waters for processing silicon chips. Our rollers help guide diamond-coated wires to cut the silicon material.
