welding without welding seam
Biggest SL4 FF innovation consists in the elimination of welding seam. This concept has been surpassed by the new system, where welding seam simply doesn’t exist anymore. Further, external welding finishing can be shaped in two ways: full zero seam (non visible welding) or engraved welding junction, mainly used in white profile. Round shaped profile with invisible welding junction look naturally perfect!
SL4-FF doesn’t need anymore corner cleaning and related rotating table. New 4 head welder has a footprint of 30sqm. only. Welding process duration has been dramatically reduced. Welding process can reach a time of 55 seconds depending on the type of profile. Extra time to add for machine loading and unloading only. Production increase of 30% up to 200% can be obtained compared to that of conventional line.
What You See Is What You Get. A problem to solve on automatic conventional welders is to upload the profile drawing, shown on a computer display or on paper. For SL4 FF welder programming it’s no more necessary to use 3D CAD programs, DXF profile drawing, selfteaching procedure or complex ISO programs. It’s enough to make a photocopy or a scanning of the real profile in your hand and upload the JPEG photo file into the machine. Expert engineer assistance or machine manufacturer intervention is absolutely no more necessary for assisting a production change or insert a new profile to weld in the machine program.
In case of different profile height due extrusion tolerance, an embedded precise measuring system looks for the medium welding height automatically, compensating difference between two profile up to 0,7 mm. (well beyond normally accepted value). In case of bigger difference, machine asks the operator for confirmation to go ahead to weld.
Increased welded angle breaking force
Each profile has its own breaking force limit value, depending by PVC compound, profile dimension and welding process quality. New SL4 FF welder performs, with same profile type, higher breaking force compared to conventional welding-corner cleaning line.
Welding process duration has been dramatically reduced. Welding time can vary between 55 and 65 sec. max , depending by profile type. Extra time to add for machine loading and unloading only. Production increase of 30% up to 200% can be obtained compared to that of conventional line.
