加热灯主要是加热塑料预成型。它们会发出红外辐射，以使塑料预成型达到适当的处理温度。因为在此温度下塑料变成柔软和塑料，所以它与加热的塑料一样易于加工。例如，当产生PET（聚对苯二甲酸酯）塑料瓶时，加热灯会均匀地加热宠物以使其软化，因此在随后的吹吹过程中，可以使用压缩空气轻松地将软化的预形成形式吹入所需的瓶子形状中。同时，使用加热灯有助于准确控制塑料的温度，从而确保瓶子的均匀厚度和稳定的瓶子质量，并提高吹气的成功率和生产效率。
Heating lamps mainly heat plastic preforms. They emit infrared radiation to make the plastic preforms reach the appropriate processing temperature. Because plastic becomes soft and plastic at this temperature, it is as easy to process as heated plasticine. For example, when PET (polyethylene terephthalate) plastic bottles are produced, the heating lamps heat the PET preforms evenly to soften them, so that in the subsequent blowing process, the softened preforms can be easily blown into the desired bottle shape using compressed air. At the same time, the use of heating lamps helps to accurately control the temperature of the plastic, thereby ensuring uniform wall thickness and stable quality of the bottle, and improving the success rate and production efficiency of blowing.
