The hot plate welding machine operates on the principle of high-temperature welding of plastic parts. It utilizes intelligent control through PLC (Programmable Logic Controller) to coordinate the movement of upper and lower molds, the high-temperature hot plate, and welding actions. The process involves placing a high-temperature hot plate between two plastic parts. As the molds move together, the plastic parts come into contact with the hot plate, causing the surface to melt within a predetermined heating time. After the melting range is achieved, the molds retreat, and the workpiece is removed from the hot plate. Subsequently, the molds quickly close, applying pressure to weld the two workpieces together. The process is completed after a certain cooling and solidification time.
Key features of the hot plate welding machine include:
1.The transmission system is driven by pneumatic, hydraulic, or servo motors.
2.It can accommodate workpieces of different sizes without limitations on the welding area.
3.It can be applied to any welding surface without special requirements.
4.The welding surface allows for plastic allowance compensation, ensuring reliable welding strength.
5.The welding procedures can be adjusted and customized to meet production needs for different materials.
The hot plate welding machine finds wide application in various industries. It is commonly used for welding tasks such as washing machine outlet plug, battery, steam iron, automotive plastic expansion tank and oil kettle, automotive lamp, glove box, bumper, dashboard, and tail lamp. It is suitable for welding plastic products with irregular shapes. The machine incorporates hot plate welding principles, PLC automation, and touch screen control for efficient and precise welding of plastic components.
