Halogen infrared heating lamps have the following advantages when used in bottle blowing machines:
Rapid heating and efficient heating: The halogen infrared heating lamp can quickly reach the required high temperature in a short time, quickly heating and softening the preform, thereby significantly improving the production efficiency of the bottle blowing machine. For example, compared with traditional heating methods, the heating time can be shortened by about 30%-50%, which greatly reduces the waiting time of the preform in the heating process.
Precise temperature control: It can accurately control the radiation of energy, and can accurately adjust the heating temperature according to the material, thickness and other factors of the preform to ensure that the preform is heated evenly and the temperature is stable within an appropriate range, making the quality of the blown bottles more stable , consistent. For example, when producing pharmaceutical plastic bottles with high-precision and high-quality requirements, precise temperature control can effectively avoid problems such as uneven wall thickness and deformation of bottles caused by uneven temperatures.
Good heating uniformity: the infrared radiation emitted can evenly cover the surface of the preform, so that the preform is evenly heated in all directions during revolution and rotation, ensuring consistent physical properties of all parts of the preform, and improving the overall quality and strength of the bottle , reducing the defective rate caused by local overheating or undercooling.
Strong penetrability: Infrared rays have strong penetrating ability and can penetrate deep into the interior of the preform for heating, bringing the temperature inside and outside the preform closer. This effectively avoids the situation where the surface is overheated and the interior is not fully softened, which is beneficial to subsequent blow molding. Operation can reduce the probability of bottle defects such as cracks and bubbles.
