Batch Pre-expander

Advantages¡º
1ÿ¢PLC with touch button fluorescence screen, auto screw raw material feed electronic weight, auto temperature control and photo-electric control the level of the raw material in feed barrel etc.
2ÿ¢The auto feed and auto weight rise production efficiency, ensure correct feed.
3ÿ¢Sealed feed barrel has constant pressure for foam, has high heat efficiency so save steam over 50% vs. continuous foamer.
4ÿ¢Foam barrel temperature is controlled through advanced proportional valve and advance guide valve, so constant temperature, pressure and material uniform are ensure.
5ÿ¢Photo-electric controls the material level so has correct volume weight and ensures uniform pearl ball density. Error less than 3%.
6ÿ¢Matched with sulphurate dry machine , it can good process from sulphurate dry, auto sizing, ball smash and auto transfer to treated material bin.
7ÿ¢The elecric appliances , pneumatic components , and valves of the machine are all well-known brand , to ensure the operational stability and reliability and service life of machine.
8ÿ¢The computer has the memory function. Which could record all information such as brands, specifications , expanding foam techniques and parameters of EPS material manufacturers . when used materials of one manufacturer is needed , just press the touch screen of computer to quickly go back to the original technique.
