Plastic Welding Technology in the field

Product catalog summary

Introduction
This document provides a comparative analysis of various plastic welding technologies used for welding a power steering fluid container made from PA 6.6 GF 30 material. The focus is on different welding methods, their principles, and boundary conditions.

Weld Design and Boundary Conditions
The weld design involves vibration with a tongue and groove approach. Key boundary conditions include the absence of particles and hairs, maintaining energy balance, and ensuring a minimum burst pressure of 2.5 bar. Similar parts should not be welded on the same machine.

Infrared Welding
Infrared welding uses contactless heating with medium and short wavelength infrared heaters. The process is characterized by flexibility in material type and part size, low investment costs, and high weld quality. The cycle time varies slightly depending on the specific setup, with a typical burst pressure of 3-5 bar.

Laser Welding
Laser welding employs quasi-simultaneous laser beams, offering high precision and flexibility for complex geometries. It requires periodic tool changes and is suitable for small volume production. The process ensures cleanliness and maintains the required burst pressure.

Gas Convection Welding
This method uses contactless heating through gas convection and radiation. It is ideal for high-volume production with minimal tool changes. The process maintains cleanliness and meets the burst pressure requirement.

Friction Welding with Infrared Preheating
Combining linear vibration with infrared preheating, this method allows for some particle presence and is suitable for high-volume production. It ensures the necessary burst pressure and offers flexibility in material and part size.

Friction Welding
Using linear vibration, this method is effective for large volumes and allows for some particle presence without affecting performance. It maintains the required burst pressure and offers flexibility in material and part size.

Conclusion
Each welding method has specific advantages and is chosen based on production volume, material type, and cleanliness requirements. The document emphasizes the importance of maintaining energy balance and achieving the necessary burst pressure across all methods.
