The process flow of the electric water heater shell mainly includes the following steps:
Material preparation: The material selection of the electric water heater shell is diverse, which can be stainless steel, plastic or other metal materials. These materials need to undergo different processing to ensure the quality and beauty of the shell.
Shell production: The production of the shell first involves protecting the internal structure of the water heater, and it is also the part that the user directly contacts, so the processing needs to consider beauty and safety. Shell processing generally includes injection molding, stamping, bending, tower connection, closing and other processes, as well as surface grinding and polishing to ensure the beauty and durability of the shell.
Turret punch press
Punching and flanging: Use a CNC multi-station punch press to punch the qualified shell sheet. This step is to enhance the structural strength and beauty of the shell.
There are two process flows for bending and seaming:
Folding Edge Pressing Laminating Machine
1.The folding and pressing machine folds and presses the shell sheet, which is not limited by the size of the shell.
Bending machine, straight seam welding machine
,2. Fold the shell with a folding machine and then weld it with a straight seam welding machine to strengthen the firmness of the connection.
Double-head Necking-in machine, special-shaped Necking-in machine
Neck processing: Neck processing is performed on both ends of the barrel body of the shell barrel that has been spot welded or riveted. This step is to enhance the beauty and practicality of the shell.
Through the above steps, the production process of the electric water heater shell is completed, ensuring the quality and beauty of the shell, and also ensuring the safety and durability of the water heater
