What Locfome Can Teach You about Duct Lock Forming Machine

source: locfome; Time: 12/20/2018

Locking machine is necessary in duct area because it can produce all kinds of types to meet locking requirements. Standard machine can process 0.5-1.5mm galvanized sheet metal. Duct lock forming machine is necessary duct machine for HVAC air duct manufacturing. Multi-function lock forming machine can form 6 shapes (7-function is available) to finish sheet jointing. Six shapes include Pittsburgh (Female), Right angle (Male), Standing seam, C shape locking pin, Curving angle and Z shape. What’s more, we can customize S shape and snap lock for sheet locking.


The standard machine can make 0.5-1.5 mm thickness galvanized sheet. The lock forming machine usually has two models. One’s max thickness is 1.2 mm, and another’s max thickness is 1.5 mm. The lock forming machine can be divided into two types according to duct shape. One type is square duct lock forming machine, for example, 6-function lock forming machine. The second is round duct lock forming machine, for example, longitudinal seam connection lock forming machine. The square duct lock forming machine is a part of rectangular ventilation air tube forming machines. It can be used with other rectangular HVAC duct machines together to achieve a whole duct production, such as TDF flange machine, pneumatic TDF sheet metal folding machine, grooving machine, electric cutting machine, square duct lock seam closing machine, clips cutting machine, etc. The round duct lock forming machine can be used with the electric rolling machine, round duct lock seam closing machine, bead roller and so on.

Locfome have optimized the structure of the machine for many times, which greatly improved our machine in speed and molding effect. We have won unanimous praise from customers all over the world.
