1. The cylinder solenoid valves are all imported, more expensive than the common cylinders.
2. Free on-line training for technology, full way tracking and testing, high sales volume.
3. All accessories are supplied by the original manufacturer and are available to customers at cost price
4. The high pressure pipe is anti-corrosion.
5. The temperature control meter is dual display, which can display the actual temperature and the set temperature. Other manufacturers can only display the set temperature and can not see the actual temperature. Red meter shows the actual temperature, green shows the set temperature
6. The operation temperature control panel is independent module which can be replaced separately. For other factories ,there is an integrated board next to the temperature control table,if one is broken ,others temerature meters all should be changed .
Learn to maintain machine :
Main Machine Daily Use and Maintenance:
1 Replace DOP in oil cup of primary-secondary pump daily;
2 When equipment stops running, swerve Start/Reset switch to reset direction, making sure cylinder rod fully soaked inside DOP liquid, in this way it can prolong service life of seal ring.
3 Check sensitivity of the equipment heating system, if anything goes wrong, please fix the problem as soon as possible.
4 When equipment isn't working, please turn off heating system timely, for not only it prevents potential danger also avoids low foaming quality cuz polyol material long-time heating.
5 Make sure turning on and off heating system in correct order. When turning on, first start main power,then turn on heating system; when turning off, first stopping heating system then turning off main power.
6 Remember to check if there's enough oil inside oil-water separator and the water expelled from the separator;
