This product production line adopts a fully automatic flip type quick change mold device. Mainly suitable for the process equipment of foam molding manufacturing of refrigerator and freezer doors. It has the characteristics of multi variety mixed line manufacturing and fully automatic mold changing. Other production lines in China require manual mold replacement, which takes 1-2 hours to manually replace a fixture and can take up to 5 hours, occupying a large amount of production time on the production line. On the other hand, the automatic mold replacement rotating door foaming line only takes 5 minutes to replace the mold, which greatly saves time and reduces production costs. The foam products produced can meet the high-performance requirements of refrigerator and freezer doors.
