Features

Sunwell SF1100 contact heating thermoforming machine makes a variety of thin gauge food containers from a wide range of materials such as BOPS, HIPS and PET. This SF1100 model machine pulls sheet into the contact heating platen to heat up without traditional heat oven to save energy and space as well as prevent sheet sagging in the oven to eliminate fire occurring.

The top moving platen is driven by servo motor, linked to the mechanical toggle system to give a precise position and motion control. The fix bottom platen consist of four layers of plates, top plate is the surface plate, which has thousands of tiny holes for air blow forming, 2nd plate is flow channels for forming air flow area controlled, 3rd plate has mounted aluminum cast-in heaters for heating and 4th plate is insulated plate. There are multiple control zones matching the forming mold sizes, safety guards surrounding the forming area and safety light curtain are mounted in the entrance and exit of forming station. The airs on/off switches are for the air precision control in the bottom platen.

The formed sheet is gripped and transferred the predetermined length by the reciprocating timing belt driven system. It could conjugate with the cross flying cutter to cut the whole web off then drop and accumulate into the stacker for additional separate cutting by off-line production. A continuous on/off edge mark puncher to make mark in the edge to identify the quantities easily for web piles cutting by off-line production. It is available for in-line process with vertical trim press for mass production.
