1. foam twice or thrice (optionally) after eps material’s once pre-expanding. for those factories whose annual output of eps material below 2000t, only one jf-1600c batch pre-expander is necessary to pre-expand heavy & light material simultaneously, which meets the production requirement, improves the production efficiency and saves space & energy.
2. adopt koyo japan’s plc programmable controller and 10’ real color touch screen in the electric system, easy to operate, running stably.
