Plastic welding solutions

BASICS

The laser beam passes through the transparent material and melts locally the absorbent polymer. Due to the heat transmission, the transparent material is melting too, and both polymers (chemically compatible) are mixed. After cooling a perfect melt will join the two materials. In order to optimize this melting, a certain clamping pressure should be applied. This whole process is local and takes a minimum of time.

Transparent plastics laser welding

BASICS

Plastics, in their natural state, do not absorb near-infrared light. Therefore the high energy of NIR lasers transmits directly through them. Laser light must be absorbed at the joint interface to generate enough heat to produce a weld. Clearweld® is a revolutionary process for laser welding plastics without the use of carbon or the addition of unwanted colour. The application of Clearweld® is the flexible solution for joining transparent or opaque thermoplastics.

ADVANTAGES

High weld speeds.

Clean, optically clear

3D joint lines capabilities.

Accurate control of weld dimension and position.

Rapid changeover to different products.

Precise control of process parameters.

Controlled localised heating for reduced risk of thermal damage

No vibration or particulate.

Pre-assembly capability.

High bond strengths

The effect of the precise heating generated produces a very small weld line and heat affected zone.

APPLICATIONS

Medical products

Packaging

Automotive components

Consumer products
