The structural design of plastic parts must first consider the following points: 1 The size of the weld is to consider whether the required strength 2 needs to be watertight, airtight 3 needs to be perfect appearance 4 to avoid melting of plastic or spillage of the composition 5 is suitable for the processing requirements of the welding head 1. JPG welding quality can be achieved through the following controls: 1 Material 2 plastic parts structure 3 welding line location and design 4 welding surface size 5 upper and lower surface location and tightness 6 welding head and plastic parts contact surface 7 smooth welding path 8 bottom die support in order to obtain a perfect, repeatable welding mode, three main design directions must be followed: 1 The initial contact of the two surfaces must be small in order to concentrate the required energy and to minimize the total energy required to complete the weld, i. e. the bonding time. 2 find suitable fixing and alignment methods, such as sockets, steps or notches for plastic parts. The welded surfaces surrounding the connection interface shall be uniform and in close contact with each other. If possible, the contact surfaces should be as flat as possible so that the energy transfer remains consistent. The Ultrasonic welding must first ensure that the injection mold is conducive to Ultrasonic welding welding, only in this way to achieve very high welding requirements, so ultrasonic welding, welding machine is the premise of the injection mold design. A good injection mold is a necessary condition for welding.
