4. APPLYING PRESSURE DURING BENDING

Once the solar guide tube has reached the desired temperature for bending, applying pressure becomes the next critical step. Uniform application of pressure during the bending process is vital to achieving a smooth, even curve, while excessive force can lead to deformation or breaks. Using physical tools like clamps,
jigs, or custom-made bending tools aids in maintaining control over the bending process.

The use of a bending jig is especially advantageous for achieving consistent angles. Constructed to hold the tube in the desired position, a jig ensures that the bends are uniform and replicable across multiple pieces. This control reduces the risk of damage and enhances the quality of the final product. Moreover, being able to reference a previously bent tube allows for a comparative analysis which further assists in achieving the required curvature.

Maintaining pressure until the material has had sufficient time to cool and set is equally important. Cooling locks the shape, removing the likelihood of reverting to its original state. For metals, this can often mean leaving the piece within the jig until it reaches room temperature. In the case of PVC, cooling can be expedited by introducing water baths or air-cooling techniques. Once satisfied with the curvature, the bent tube can proceed to fitting or installation.

5. SAFETY PRECAUTIONS DURING BENDING

Focusing on safety throughout the bending process is non-negotiable. The risk of injury or damage escalates significantly when using heating elements and applying force to materials. Thus, implementing safety measures safeguards both the individual and the equipment being utilized.
