手动喷粉线固化炉是手动粉末喷涂生产线中的核心终端设备，主要用于对已完成手动喷粉的工件进行加热固化处理。其核心作用是通过精准控制温度（通常为 160-220℃）与固化时间（15-30 分钟，依粉末类型调整），使工件表面的粉末涂料熔融、流平并交联固化，最终形成均匀、坚硬且附着力强的保护涂层，大幅提升工件的耐腐蚀性、耐磨性与外观质感。
该设备通常采用电加热或燃气加热方式，配备热风循环系统确保炉内温度均匀（温差≤±5℃），避免工件局部固化不良；同时设有进出料口与简易输送装置（如辊道、托盘），适配手动喷粉线的间歇式生产节奏，操作便捷，维护成本低。广泛应用于中小批量、多品种的五金件、工具、小型机械零部件等手动喷粉生产场景，如门把手、五金支架、小型电机外壳等工件的涂装固化。
The Manual Powder Spray Line Curing Oven is a core terminal equipment in manual powder coating production lines, mainly used for heating and curing workpieces that have completed manual powder spraying. Its core function is to precisely control the temperature (usually 160-220℃) and curing time (15-30 minutes, adjusted according to powder type), so that the powder coating on the workpiece surface melts, levels and cross-links for curing. Finally, it forms a uniform, hard and strongly adhesive protective coating, which greatly improves the workpiece's corrosion resistance, wear resistance and appearance texture.
This equipment usually adopts electric heating or gas heating, and is equipped with a hot air circulation system to ensure uniform temperature inside the oven (temperature difference ≤ ±5℃), avoiding poor local curing of workpieces. At the same time, it is provided with inlet and outlet ports and simple conveying devices (such as rollers, pallets) to adapt to the intermittent production rhythm of the manual powder spray line, with convenient operation and low maintenance cost. It is widely used in manual powder spray production scenarios of small and medium batches, multi-variety hardware parts, tools, small mechanical parts, such as door handles, hardware brackets, small motor housings and other workpieces for coating curing.
