Profile seal bonding – PDK
Profile seal bonding (PDK) is a process in which self-adhesive profile seals are applied to the workpiece in fully automated systems. Depending on your requirements, you can choose between an application of endless seals or ready cut lengths of seal profile.
Application systems for profile seal bonding
ATN has developed fully automatic profiled seal application systems for self-adhesive rubber seals. These are characterised by their modular design, which allows tailored systems to be assembled and adapted to your specific process requirements.
ATN systems ensure high-quality and exceptionally cost-effective application of adhesive seals, thanks to a sophisticated overall concept with technical features that include fully automatic joint splicing and integrated quality monitoring.
1. Workpiece holder
An individual robot-guided gripper picks up the workpiece on which the door seal rubber will be applied. We also supply combination grippers for multiple door types as well as a gripper quick-change system.
2. Adhesive seal application
A stationary application head, which can be adjusted for different thicknesses, applies the rubber seal. The application head also ensures the required contact pressure, compression and position.
3. Material supply system
An automatic unwinding unit supplies the application head with material and can be fitted with single-use or reusable roll trolleys which are then evenly unwound. The material supply system can also be replenished with the cells in automatic mode by fitting a buffer reservoir.
4. Buffer storage
This ensures uninterrupted production (buffering of up to 65 m of seal) as well as tension-free seal profile storage and feeding to the application head, which means that the seal is handled gently throughout. The buffer reservoir can be fitted with optional air conditioning to prevent temperature changes from affecting the seal profile’s material properties.
5. Quality monitoring
Guaranteed, assured quality is a priority at ATN. That’s why we developed a position-detection system which measures the relative position of the seal to the door after application. The advantage of this is that measured values are always correctly recorded and evaluated in any situation regardless of gripper type, door contour or sensor position.
6. Additional options
You can also incorporate additional options into the door seal application process, such as drain hole drilling or gluing surface cleaning.
