Plastic laser welder
Laser welder jointed products in different penetrability, absorptiveness by heating through laser beam.
It is suitable for precise and three-dimensional model products.
It is widely applied in auto industry, medical industry, electronic electricity industry, semiconductor industry.
Principle
- The laser beam penetrates the upper transparent joining material
- The laser is completely absorbed in absorber material.
- The absorptive material starts to melt at its surface.
- The upper transparent joining material and absorber material are joined together under pressure.
Feature
- High bond strength/hermetic seal. without contact.
- Control precision energy and heating range.
- Maintain high strength of welding, Allow welding of parts with many shapes/geometries.
- Lower residual stress and No change
- No damage to surface and No pressure into part inside
- No occur burr after welding
- Application : car industry, medical industry, Electronic field, Semiconductor industry, textile industry.
Suitability of materials
Requirements
- The two components must be thermoplastic and chemically equal or very similar, otherwise, the adhesion is merely based on indenting of the components.
- The transparent material can be milky(glass fiber reinforced). The scattering of the laser light does not make the welding process impossible.
- The transparent material can contain special pigments.
- Reliable and reproducible results are only produced with exact temperature control.
Control
- Compare 10,000 times per second the set-point temperature with measured temperature and control heat source(Laser, Inductor)
- Store up to 255 process scripts
- Ok/Not ok decision during process with creation of an error signal
- Write process scripts by simple programming language.
- Store up to 500,000 processes to the internal flash disk.
- Self-diagnostic system
Suitability of materials
- Controllable energy Insert-mediated :
Energy is transferred with clear direction and capacity. Therefore Laser welding is a very accurate and highly reproducible.
- Precision processing :
Laser welding need not contact and vibration, therefore change of component is not occur by lower temperature.
- Reliable joint
Abrasion of the welded joint does not occur. Strength of products is typically more than 90% of the internal material strength.
- Fast cycle time
- Environmental friendly machining :
Saving raw material, High energy efficiency, No smoke or fumes
- Post process is unnecessary.
- CNC, Robot system-99% of fusibility.
