Laser Plastic Welding

As the laser passes through the polymer beam scattering can occur due to the presence of crystalline zones and glass fibers.

Laser plastic welding. Materials selection for welding. Chacun de nos développements définit l état des possibilités techniques. One of the most common issues that can affect plastic welding quality is the reduction of your beam s intensity. When laser welding plastics using the transmission welding method two types of thermoplastics are joined with one another.

The concept involves passing a focused laser beam through an upper laser transmissive part to the interface of the two parts to be joined. Providing practical and technical advice for manufacturing products in thermoplastics textiles and thermoplastic composites using laser welding. How laser inconsistencies affect the quality of your plastic weld. Pigments coloring agents and other compounds also absorb some of the beam s energy as it travels to the weld seam.

Training and teaching. We provide highly reliable systems for the automotive and other industries suitable for a variety of batch and component sizes. As far as possible the gap should be smaller than 150 μm here. Laser plastic welding also often referred to as through transmission welding is a process of bonding plastic using focused laser radiation.

Transmission laser welding when first being reported in 1985 transmission laser welding was carried out with an ir transmissive plastic material for the upper section and a carbon black loaded plastic for the lower layer. Laser welding plastic components. The absorbing plastic melts the transparent joining area. Nos systèmes laser novateurs pour souder les plastiques permettent d appliquer de nouvelles méthodes de fabrication dans les secteurs de la construction automobile la technique médicale les capteurs l électronique et la technique de microsystèmes.

The mating parts must be pressed together using a suitable fixture in order to ensure sufficient heat transfer. Laser plastic welding with diode lasers supplements traditional welding methods such as ultrasound vibration or hot plate welding. The carbon black absorbs and heats in the laser beam to generate a weld at the interface between the two pieces. Transparent plastic laser welding.

Supply of clearweld absorbers. R d for product manufacturing. The laser passes through the transparent mating part and the absorbing mating part is heated. It combines the advantages of contact free welding without forming fluff or excessive melting with the possibility of welding with a measurable setting path.

The machines can either stand alone or be integrated into your production line and are ideal for. Une spécialité de leister exclusive dans le monde est le soudage globo welding breveté et récompensé où des pièces en plastique. Also known as clear on clear plastic welding this method is ideal when both plastics are mostly transparent or in the infrared wavelength range. When two transparent parts are held together the laser transmits its energy through the upper layer like in transmissive welding.

In order to ensure a permanent connection. The process is very much different than traditional metal welding. Laser radiation is shot through an upper transmissive plastic part and the energy is absorbed by the lower layer creating heat at the interface and melting both parts.
