Problems solved by technology

[0002] During the production process of the profiled plastic extruder, the surface of the shaping die is prone to scale and lubricant crystals that adhere to the surface and are difficult to remove. After the shaping die is online for a period of time, a large amount of scale and lubricant crystals will be generated. It will cause certain damage to the appearance of the produced product and affect the quality of the product. It is necessary to stop the machine to remove the shaping mold and clean the scale and crystals in the ultrasonic mold cooking machine. The surface of the mold can only be removed and the production can continue on the line, which seriously reduces the production efficiency. , which increases the production cost
