Uses of segmented wire infrared heating lamps in the industrial heating field:
Metal processing: In the process of metal heat treatment, segmented wire infrared heating lamps can be used for local heating. For example, before metal welding, preheating the welding part can effectively reduce welding stress and deformation.
Because it can be controlled in sections, for metal parts with complex shapes, such as mechanical parts with various bends and protrusions, it can accurately heat only the areas that need to be welded to avoid the performance of other parts being affected by heat. At the same time, in the heat treatment processes such as quenching and tempering of metals, by adjusting the power of heating lamps in different sections, a temperature gradient can be created to meet different process requirements.
Plastic molding: In the molding process such as plastic extrusion and injection molding, segmented wire infrared heating lamps are used to heat molds or plastic raw materials. For example, in injection molds, using its segmented heating characteristics, different temperatures can be maintained in different areas of the mold to improve the flow properties of the plastic in the mold and make the quality of the molded plastic products better, such as reducing surface shrinkage marks and improving dimensional accuracy.
Moreover, for the extrusion processing of large plastic sheets, the segmented wire heating lamp can reasonably distribute the heat of each segment according to the width and thickness of the sheet, ensuring uniform heating and continuous and stable extrusion of the sheet.
Glass processing: In the process of glass manufacturing and processing, segmented wire infrared heating lamps play an important role. For example, in the hot bending process of glass, the glass needs to be bent at a specific temperature.
By controlling the heating lamp in segments, different parts of the glass can be accurately heated so that it can be bent according to the design requirements. For the processing of some large architectural glass or automotive glass, this precise segmented heating method can effectively prevent the glass from breaking due to local overheating, while also improving processing efficiency.
