If there is a thin flange in the mold, the steam is best to pass through the flange so that the raw materials sandwiched in the flange can also be steamed; Pressure maintenance: After the horizontal steam is passed, it needs to go through the pressure maintenance or double-sided steaming process.epp core material foam plastics'>the molding process of core material foam plastics: Before passing the steam After that, the temperature inside the mold will generally reach 140°C.
At this time, close the condensate China cashem valve on one side and open the steam inlet valve. During this process, open the steam inlet valve and close the condensate drain valve to make the pressure gradually reach the peak value. Demolding. Three steps to pass the steam into the mold: steam flushing: [...]
