Plastics processing is one of the fastest growing application areas for laser technology.
Read MoreLaser Welding Comes of Age
Laser welding is gaining acceptance as a specialized method for joining plastic parts that are sensitive (e.g., contain circuit boards), involve complex geometries, or have strict cleanliness requirements (medical devices). So far, most of this activity has taken place in Europe.
