[ Problem Point ]
When heat spreads over a wide area, unnecessary parts of the tube body also receive heat, posing a risk of deformation and deterioration. As a result, there were concerns about a decline in the overall product quality and reduced yield.
[ ⇒Kaizen Point ]
Since the halogen glass rod heater does not directly contact the tube, it suppresses unwanted heat transfer and prevents thermal damage to other parts of the product. Consequently, the overall quality of the tube is maintained.
