Systems and apparatus for manufacturing multiple large-sized sandwich panels

A method for manufacturing multiple sandwich panels, comprising:

• positioning a first flat portion on a bottom mold;
• forming a first sealant pattern on the first flat portion;
• positioning a first insulation layer on the first flat portion;
• forming a second sealant pattern on the first insulation layer;
• positioning a second flat portion on the first insulation layer;
• positioning an intermediate mold on the second flat portion;
• positioning a third flat portion on the intermediate mold;
• forming a third sealant pattern on the third flat portion;
• positioning a second insulation layer on the third flat portion;
• forming a fourth sealant pattern on the second insulation layer;
• positioning a fourth flat portion on the second insulation layer;
• positioning a top mold on the fourth flat portion;
• and
• pressing the top mold toward the bottom mold under a predetermined temperature profile during a predetermined time period.

A system for manufacture multiple sandwich panels, comprising:

• a control unit;
• a memory;
• a surface processing module configured to prepare a rolled material by at least one surface treatment process;
• an environmental management module configured to control and management environmental factors during the surface treatment process and a pressing process;
• a sealant module configured to apply sealants in sealant patterns on surfaces of flat portions of the rolled material and insulation layers;
• a pressing module including a top mold, an intermediate mold, a bottom mold and configured to press multiple pairs of the flat portions and insulation layers so to form multiple sandwich panels in the pressing process,
• wherein the at least one surface treatment process and the pressing process are monitored and controlled by the control unit;
• and
• wherein the sealant patterns are formed in accordance with a predetermined pattern stored in the memory.
