Laser Welding System for the Plastic Industry

Panasonic Industry Presents Laser Welding Solutions

The requirements in the plastic industry are high: While manufacturing and production process is accelerating, products are becoming ever more complex. All products should be marked for identification to ensure product quality and to allow for tracing in case of consequential damage.

The experience with MOFPA (Master Oscillator Fiber Power Amplifier) fiber laser technology from Panasonic Industry Europe GmbH, Ottobrunn, Germany, has been incorporated into the development of the new VL-W1 laser welding system.

According to the company, fiber laser technology offers what is currently the most energy-efficient and cost-effective system for laser processing of plastic parts, as this laser can operate with practically no maintenance.

Advantages of Laser Welding

Laser welding of plastics offers decisive advantages compared to conventional bonding technology (ultrasonic welding, gluing, etc.). Laser welding is a clean and precise process in which the plastic components can be joined without visible welding seams. Joining by means of laser energy does not leave any adhesive residue and also produces no wear particles, which can lead to problems on the finished component later on.

The process energy required for bonding can also be introduced selectively and with only slight pressure on the bonding surface for laser-welded components in comparison to other methods. That not only ensures stress-free joining of components with very little warping, but is also extremely energy-efficient. Laser welding can be adapted very flexibly to the components being welded thanks to the laser systems of the VL-W1 series.

The individual process steps can be monitored and documented completely and are therefore useful for quality control.

New Integration Module

An integration module was designed especially for Panasonic Industry‘s laser welding system VL-W1. It corresponds exactly to the dimensions and features of the laser welding system. This makes it easier for integrators and machine builders to implement the laser welding process for plastics into their production lines. The construction work and the risks that occur when a new process has to be integrated into an existing line are minimized by the I-Module.

A large field of operation (200 mm x 150 mm) makes it easy to insert various components. Different clamping mechanisms allow tension forces from 400 N up to 3000 N. A position measuring system with a resolution of 0.003 mm assures a very precise placing within the VL-W1.

Customized Clamping Units

Panasonic Industry Europe also offers a good surrounding for the VL-W1 series: the LCP-3000 workstation. This workstation is suitable for a wide variety of laser welding applications due to possible servo-driven X-,Y- and Z-axis tables or servo-driven rotary indexing table. Even a 360°-solution with rotary shaft is available. The LCP-3000 workstation is equipped with a servo-driven cabin safety door and an internal extraction unit with an optional filter insert. The company offers customized clamping units for every application.
