Product Details

Ⅰ.Product Classification:

 PU elastomer products 


Ⅱ.Functions and features:

1. The raw material tank adopts the hot air circulation of electric heating(patented technology), which makes heating faster, efficient, energy saving 50% , safe and environmental.


2. High-temperature resistant low-speed high-precision metering pump; accurate matching, flexible adjustment and measurement accuracy error:≤±0.5%.

3. Independent PLC control system in the branch temperature controller of each group , with special electric heating system, oven, piping and vales which can be adjusted separately; multi-point temperature control device is used to ensure that the raw material to maintain a constant temperature throughout the cycle process; temperature error:≤2℃.

4. The mixing device is reasonably designed: homogeneous mixing,light and durable.

5. Equipped with the color paste control system and the color paste directly goes into the mixing device; different colors can be switched at any time; the mixing is uniform and the metering is accurate.

6. Adopt the imported PLC controller to monitor the entire control system; it will automatically make judgment of abnormity, diagnosis and alarm, abnormal factors display, PLC module control, casting, automatic cleaning and air impact; stable performance and strong operability.

7.Automatic degassing system, ensure the products have no bubble.

8. Constant-Pressure device ( patented technology), which removes flow error and improve measuring accuracy.

9. The closed loop automatic control of the hot air circulation system has solved 

the technical problems of easy oxidation and carbon deposition.

10.Frequency-controlled drives.

11.Effective energy saving because of thick insulation layers on the tank cabins.

12.Excellent mixing chamber and agitate geometry for optimum mixing quality even when the raw materials are difficult to mix.

13.ZeCheng 's machine head can be completely dismantled , easy to clean.

14.Electric heating type mixed head.

15.Multi component agitation system can be added.



Ⅲ.Application:

The machine is fit for making PU elastomer products with middle and low hardness.
