Laser Plastic Welding Myths Debunked

November 30, 2020 Laser Welding

There are several myths about laser plastic welding machines and their technology. Let us clear things up a bit. These are some of the top laser plastic welding myths DEBUNKED...

MYTH: Laser plastic welding is only for small parts.

Laser plastic welding works well for both small and large parts. The technology precisely applies the energy and controls the size and path of the beam spot. In the tightest applications, we use masks over the part to constrain the laser energy. Laser plastic welding is also used on large parts. Quasi-simultaneous laser systems can handle parts within a 39" square. And adding a 3rd axis to the scanner extends the possible size even larger. We can also use contour welding, which physically moves the laser head around the part. Large or small, laser can do them all!

MYTH: Laser plastic welding is unsafe.

Laser plastic welding is safe to use. As with all welding processes, you must have the proper safety measures in place. Laser is no different. We shield the operators from the IR energy source. At Extol, we take safety seriously and have a Certified Laser Safety Officer on our team. This person ensures our equipment meets all safety regulations. The result is a safe laser plastic welding solution.

MYTH: Laser plastic welding is expensive.

Laser plastic welding does not have to be expensive. There are many factors to consider when developing a welding solution: budget, part requirements, cycle time, and more. Extol's approach to laser plastic welding is different than most. We configure our solutions around the application's needs and the customer's desires. So, we can balance what's most important and deliver a cost-effective solution.

MYTH: Laser plastic welding is slow.

Laser plastic welding is actually one of the fastest plastic welding technologies available. The precise and focused energy allows for quick and efficient heating of the plastic. It's possible this myth comes from cramming applications into one-size-fits-all laser machines. That's not how we do it at Extol. Our laser solutions are fast because we apply the right laser system to the right parts.

MYTH: Laser plastic welding is difficult.

Laser plastic welding does not have to be difficult. At its core, laser welding melts plastic with IR energy and welds it together with pressure. It is a powerful technology and a clean, precise way to weld plastic. Partner with an experienced manufacturing technology company like Extol. We make laser plastic welding easy.

So, the next time you have a plastic welding project, consider laser. The process welds both large and small parts. It's safe, cost-effective, fast, and easy with Extol as your technology partner.
