273mm 220v 1000w Sk15 Clear Ir Lamp Halogen Infrared Heat Lamp For PET Blowing Machine Goldisgood

Application of halogen heating lamps in bottle blowing machinesPreheating of preformsPreheating of preforms is a critical step in the bottle blowing process. Halogen heating lamps can effectively preheat preforms. The infrared radiation they emit can penetrate the preform material, causing the temperature inside and outside the preform to rise evenly. For example, for PET (polyethylene terephthalate) preforms, preheating with halogen heating lamps can raise the preform temperature to a suitable range (usually around 100-140\\u2103), which is conducive to the forming of the bottle body during the subsequent bottle blowing process.Compared with other preheating methods, halogen heating lamps have a relatively fast preheating speed. It can heat a large number of preforms to the required temperature in a short time, thereby improving the production efficiency of the bottle blowing machine. Moreover, this preheating method can accurately control the temperature, and by adjusting the power and irradiation time of the heating lamp, the consistency of the preform temperature is ensured, which helps to produce bottles of uniform quality. Auxiliary heating for bottle body formingDuring the bottle blowing stage, when the high-pressure air blows the preform into the bottle body, the halogen heating lamp can provide auxiliary heating. At this time, the heat from the heating lamp can help the bottle material better fit the inner wall of the mold and make the bottle surface smoother. For example, for some bottles with complex shapes or special design requirements, such as cosmetic bottles with concave and convex textures, the auxiliary heating of the halogen heating lamp can ensure that these details of the bottle can be accurately formed. At the same time, auxiliary heating can also reduce the stress concentration phenomenon that occurs in the bottle during the blowing process. Stress concentration may cause quality problems such as cracking of the bottle during subsequent use. The heating of the halogen heating lamp makes the bottle material softer and more uniform, reduces the possibility of stress generation, and improves the quality and durability of the bottle.
