Quality Assurance for Laser Polymer Welding Processe

Quasi-simultaneous Laser Welding

Transmission laser welding of polymers is a well-established industrial joining method, its reliability makes it particularly suitable for applications where very high weld seam quality is specified. A number of quality assurance methods are available when using this technology to safeguard the specifications demand for quality. These quality assurance methods are suitable for implementing a zero-error strategy, under very economically attractive conditions. This three-part series of articles discusses the different approaches.

Competing Processes – Adhesive Bonding versus Laser Welding

The increasing adoption of laser welding is due in no small part to the many technical advantages it offers. With regard to the economic advantages, prejudices still exist on account of higher investment costs for suitable materials. Any comparison with other processes must consider all aspects.

Black-to-Black Laser Transmission Welding

Laser plastic welding, also known as through transmission welding, is quite simple in its essence (see Basic Process Video). 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.

However, the process does not always seem so intuitive. For instance when welding colored materials, specifically ones with opaque upper layers. Read the rest of this entry »

Quality Control – Laser Plastic Welding, Impossibly Consistent

Quality control is a main factor in the development and manufacture of any new product. From pre-production testing to in-line process monitoring, control mechanisms often drive much of the process of bringing a product from concept to production.

Is Laser Plastic Welding Economical?

Laser plastic welding is becoming well known for its ability to join complex and detailed parts. In fact, the technology is driving innovation for products that were once not possible in the medical, automotive and consumer electronics industries.

However, there still exists a stigma that laser technology cannot compete economically with other joining methods. Despite the technical advantages, the initial capital investment of laser systems has been a stumbling block for the technology.
