All the products are manufacture under Standards such as ASHRAE, SMACNA AND DW-142 We produce and supply the products under brand name VECON. The introduction of VECON products are the results of times demand for quality oriented product and the hand of well experience technical team with prime motto to provide best quality product in the market. Our factory at Kochi has proven its capability of producing ducts of international standards for many prestigious projects.
In an HVAC system there are many times when there is a need for ducts for supplying conditioned as well as fresh air to a particular indoor area from the machine and because of this reason duct system works have gained importance in HVAC system. Ducts are used for heating, ventilation and air conditioning to deliver or remove air.
Ducts are available mainly in two types Rectangular and Circular ducts but can be made of different material like G.I Mild steel, Stainless steel and aluminum. Installing Duck work has many advantages like reducing electricity bills by correct channeling and sizing according to the airflow but this can be achieved only with good quality ducts and qualified installation technicians.

Duct Manufacturing & Production Process
After receiving the tagged drawing a fabrication schedule is prepared for the ducts to be made after coordinating with the customer
The fabricator receives the fabrication schedule and dimensions of the duct to be manufactured
CNC Operator inputs the data into the CNC machine such as coil line or Plasma cutter
The square ducts are processed through the CNC operated Coil Line machine to make ducts of 1200mm (standard length). This duct is then passed through the duct zipper for seam joining and Automatic Precision Cleat bending machine for “C” cleats to form complete duct. At each stage, a factory foreman is continuously monitoring the quality. After completion these ducts are sent to quality inspection by Quality Assurance Department.
The Duct fitting are processed through the CNC controlled Plasma Cutting System. The fabricator feeds the data in the system and the system automatically nests the parts on the sheets with the precise measurements. The Plasma Cutting tables are then loaded with GI steel and the fitting parts are cut. The fabricator identifies the pieces with the help of layouts prints and marks the dimension along with fabrication instructions that deal with bending, rolling, etc. These parts then are passed through duct beader to strengthen the sheets by grooving them.
After beading the parts are passed through various processes such as lock- forming, rolling, bending, flanging, spot welding and cleat bending as per the requirement of the fitting. The fitting parts are then moved to the assembling section, where the parts are assembled, while it’s add on flange are fixed, stiffness for large ducts are added etc. The factory foreman monitors all the processes so as to ensure the highest quality of products
The assembled duct fitting are then sent to the quality assurance and inspection department.
