The manufacturing process of TDF flange rectangular ducts is an efficient and economical method for making air ducts. The following is a detailed summary of its manufacturing process:
1、 Material preparation
Plate selection: Choose suitable metal plates based on the usage scenario and requirements, such as galvanized steel plates, stainless steel plates, etc. The thickness and quality of the board should meet the design requirements.
Tools and equipment: Prepare tools and materials such as CNC cutting machines, plasma cutting machines, common plate flange forming machines, biting machines, sealants, and reinforcements (if needed).
2、 Production process
Material cutting
Use a CNC cutting machine or plasma cutting machine to accurately cut the sheet according to the design requirements, ensuring accurate dimensions.
Common plate flange forming
Send the cut sheet metal into the common plate flange forming machine, and use mechanical pressing to bend and press the edges of the sheet metal into the shape of a common plate flange. The common flange and air duct sheet are integrally formed, reducing the use of connectors.
Bite connection
Align the common flange of two boards and connect them together using a biting machine or manual biting tool. The bite connection should be tight and firm to ensure the sealing of the air duct.
Sealing treatment
Apply sealant or install sealing gasket at the joint of the common flange to ensure the sealing performance of the joint. Sealing treatment is a key step in preventing air leakage and should be operated carefully.
Reinforcement treatment (if necessary)
For large-sized or high-pressure air ducts, reinforcement components such as angle steel, flat steel, etc. can be installed inside the ducts to improve their strength. The reinforcement component should be tightly connected to the duct panel to ensure the reinforcement effect.
3、 Quality inspection
Appearance inspection: Check if the surface of the air duct is flat, undamaged, and free from deformation.
Size measurement: Use measuring tools to check whether the size of the air duct meets the design requirements.
Air leakage test: Conduct air leakage test on the air duct according to relevant standards to ensure good sealing of the air duct.
4、 Key points of production process
Accurate cutting: Ensure accurate cutting dimensions of the board and reduce errors.
Tight bite: The bite connection should be tight and secure to prevent air leakage.
Good sealing: The sealing treatment should be carefully operated to ensure good sealing at the connection.
Reasonable reinforcement: According to the size and pressure requirements of the air duct, reinforcement components should be set reasonably to improve the strength of the air duct.
