Plastic welding | spot welding：
The ultrasonic spot welder is a mobile ultrasonic welding device that enhances wide welding applications. For example, the processed welding head can penetrate from the upper part to the lower part to generate heat after the plastic material comes in contact with the surface of the mold, causing a plasticization phenomenon to fuse the material. The plastic material will flow upward after being compressed to form a protrusion.
