What does color have to do with laser plastic welding? Everything. Especially if your consumer brand of audio earbuds is recognized globally by its distinctive shade of white, or if your customers expect classy, glossy black appointments on their luxury automobiles. The fact is, there are a lot of very cool things you can do with colors and other additives in the laser plastic welding process, especially in the automotive and consumer product industry – but many designers and engineers aren’t aware of these capabilities. We’ll enlighten you now about the plethora of possibilities and how we can help you add color to your product designs.
With traditional vibration welding methods, welding ribs are the ugly stepsisters that designers and manufacturers have learned to live with as a tradeoff to making attractive, aesthetically pleasing translucent plastic components. Any type of friction weld – vibration, ultrasonic, or RF welding – regardless of the vibration frequency, causes the two plastic components being joined to have welding ribs, or molded ridges that are melted by friction as the two parts are welded together to create the bond. Frankly, the result is not pretty and a detriment to producing an attractive, strong seam.
You can’t fix what you can’t see. How many times have you wished you could monitor exactly what’s going on in your laser plastic welding system during production? Fortunately, today, some laser plastic welding systems provide that high level of visibility with their built-in quality control features.
Batman and Robin. Lucy and Ricky. Roy Rogers and Trigger. You get the picture – the perfect match drives fame, fortune, and legendary success. In the auto industry, the perfect match of laser plastic welding and polymers for sensor housings makes all the difference between high performance, best-selling models and unattractive, unreliable lemons.
In the not so distant past, there were limited choices for welding plastics – i.e. gluing or vibration/ultrasonic welding; and while both have their advantages and ideal applications, they are not up to the task of handling today’s smaller and more sophisticated product designs that use plastics.
It can be confusing to compare typical plastic welding methods and determine which one is best for joining plastics in your product design application. In this post, we’re going to give you a quick Plastic Welding 101 tutorial on the pros and cons of each type of plastic joining process and provide you some guidelines on ideal applications for each.
