Helical tube coils are formed through processes like roll bending, CNC tube bending, induction or flame heating, or manual bending to achieve spiral shapes for various applications.

 

 

   - Process Characteristics: Simple operation, requiring experienced craftsmen to manually operate using manual bending tools.

   - Applicable Scenarios: Suitable for small-scale production, special shape requirements, such as art, decoration, etc.

   - Advantages: High flexibility, strong adaptability, and can adjust shapes and sizes as required.

   - Disadvantages: Low production efficiency, limited precision, and relatively high cost.

 

 

   - Process Characteristics: Utilizes computer numerical control (CNC) technology to automatically complete precise bending of the coil according to pre-programmed instructions.

   - Applicable Scenarios: Suitable for large-scale production, complex shape requirements, such as industrial manufacturing, construction, etc.

   - Advantages: High efficiency, precision, and consistency, suitable for mass production.

   - Disadvantages: High equipment investment and maintenance costs, high technical requirements for operators, not suitable for small batch production or customized projects.

 

 

   - Three-Roll Bending Machine:

     - Process Characteristics: Bends the tube into a spiral shape through the coordinated action of three rollers.

     - Applicable Scenarios: Suitable for larger diameters and thicker-walled tubes, with higher production efficiency.

   - Four-Roll Bending Machine:

     - Process Characteristics: Achieves higher processing precision and stability through the coordinated action of four rollers.

     - Applicable Scenarios: Suitable for manufacturing spiral coils with higher precision and complex structures.

 

 

   - Flame Heating:

     - Process Characteristics: Softens the tube by flame heating, and then bends it using mechanical force.

     - Applicable Scenarios: Suitable for larger diameters and thicker-walled tubes, but attention needs to be paid to controlling heating temperature and uniformity.

   - Resistance Heating:

     - Process Characteristics: Generates heat by passing current through the tube, locally heating it to soften.

     - Applicable Scenarios: Suitable for cases with strict requirements for heating temperature, such as high precision and complex shape coil manufacturing.

   - Medium Frequency Induction Heating:

     - Process Characteristics: Locally heats the tube through the induction heating system, achieving rapid and efficient deformation of the tube.

     - Applicable Scenarios: Suitable for various types of tubes, achieving efficient and precise production.

 

 

   - Cold Bending Machine:

     - Process Characteristics: Bends the tube at room temperature without heating.

     - Applicable Scenarios: Suitable for cases sensitive to temperature or requiring material performance to be maintained, but requires greater force.
