The Promac DFN632 drills the spacer frame externally using 2 drills set at 90° to enable the desiccant material filling, the 2 holes are then hermetically sealed by the application of butyl rubber. The spacer is drilled externally to leave the receiving walls intact. The machine is also capable of managing shaped spacer filling in addition to adapting to the variations in spacer dimensions. 1 to 4 sides of the frame can be filled, above all using either one or both heads. Only one operator is needed to manage the simultaneous production of the two machines: Art. PBN632, the automatic spacer bender and desiccant loader. The machine can use common 0.5 to 0.8mm grade desiccant material. The high productivity and automation are enhanced by the use of the optional automatic frame loading – unloading accessory. The work process does not affect the quality of the first sealing.
