Laser plastic welding pdf. Instead of simply passing through the second layer however some of the energy. Laser plastic welding is a method of bonding two or more thermoplastic components together. In contrast to ultrasonic welding laser welding procedures also permit the jointing of components with. Accordingly plastic laser welding is predestined for applications in which sensitive electro nics are located in parts that have to be.

A technical brief for engineers design parts for laser plastic welding keywords. When laser welding plastics using the transmission welding method two types of thermoplastics are joined with one another. There have also been developments in textile joining and in joining dissimilar materials e g. This fact makes the procedure especially interesting for the manufacture of medical devices where the highest demands are placed on material and function.

Welding of plastics is of practical importance in many automotive medical and electronic packaging applications. When two transparent parts are held together the laser transmits its energy through the upper layer like in transmissive welding. Also known as clear on clear plastic welding this method is ideal when both plastics are mostly transparent or in the infrared wavelength range. Josh brown lpkf laser electronics subject.

From materials selection and design to integration and optimization we are dedicated to being a re sourceful partner every step of the way. Jones in handbook of laser welding technologies 2013. Laser plastic welding plastic welding plastic joining bonding transmission lpkf infrared contour quasi simultaneous hybrid joint design guide recommendations techniques created date. Leister has been the internationally.

Moreover the process is totally free of debris unlike other welding processes. Although there are many methods for joining thermoplastics laser plastic welding has a few clear advantages. The process relies on passing. Plastic laser welding is noted for its very readily controlled local and non contact introduction of heat minimal heat influence zone and low mechanical stress on the adherends.

The laser passes through the transparent mating part and the absorbing mating part is heated. Higher joining quality minimal resulting flash or particulates higher quality controls less stress to the component and can weld complex and intricate shapes. Transparent plastic laser welding. Laser plastic welding design guidelines light author.

In plastics laser welding generates a very clean weld seam that does not leave behind any residues and loose particles around the seam. We take pride in sharing our knowledge to help lock in optimum process parameters to gether with our customers. The mating parts must be pressed together using a suitable fixture in order to ensure sufficient heat transfer. Joining partners for the laser welding process.

Furthermore only few furthermore only few materials combinations are possible for welding dissimilar plastics.
