Configurable, cost-effective laser plastic welding that meets your needs
Are you tired of trying to fit your plastic laser welding application into the constraints of one-size-fits-all laser welding machines? At Extol, we take a different approach. We design each laser welding solution around your application. That way, you get the optimum performance and cycle time for your needs.
The Laser Plastic Welding Process
Laser plastic welding uses a precise IR laser beam that is transmitted through a transmissive material and absorbed by an absorptive material. The two materials are held in tight contact with each other and the joint between them heats up and melts as energy from the laser is absorbed. The result is a clean weld with minimal flash.
Clamp
The two parts are clamped together with the IR transparent material on top and the absorbing material on the bottom.
Heat
The laser is transmitted through the top component and absorbed by the lower component, heating and melting the joint.
Cool
The laser turns off and the clamping force is maintained to allow the joint to cool and solidify.
We’ve been doing IR for 20+ years.
Application-driven laser welding solutions
Many laser welding applications need a special solution to optimize speed and performance. We custom tailor each laser welding machine to the application. That means the machine can be as large or as small as you need it to be. It can apply force using whatever method you want. And it can use the laser technology that is best suited for your parts.
How Extol guides you to the best laser welding solution
COLLABORATE – We work with you to gain a deep understanding of the needs for your specific application.

Not only do we provide laser welding guidelines to get you started, but we review your design and provide specific recommendations. Beyond that, we validate your design by welding and testing the assembly with equipment in our lab.
CONFIGURE – Using what we’ve learned about you and your application, we configure a solution that is perfect for your needs.
DELIVER – We design, build, and deliver your laser welding equipment. But we don’t stop there. Our exceptional team supports you from launch through the life of the program.
Laser Welding Benefits
Clean
Laser welding can minimize or eliminate unwanted particulate and visually unacceptable flash by precisely applying the right amount of energy to the weld surface. Excess heat isn’t needed to generate strong, clean, and repeatable welds.
Fast
Extremely focused energy means the plastic is heated exceptionally fast. This translates to fast weld times.
Precise
Miniaturized part designs and closer proximity of internal components is possible with the control and accuracy of Extol’s laser plastic welding system. The energy goes exactly where it needs to on every part.

A properly designed weld joint is critical to achieving the desired weld strength and appearance. Follow our easy-to-use guidelines to optimize your part design for laser plastic welding and achieve the best weld possible.
Contour
Contour laser welding uses one continuous pass of the laser along the weld path with enough energy to melt and weld the parts. This works well for flat to flat weld joints.
Quasi-Simultaneous
Quasi-simultaneous laser welding uses many very fast passes along the weld path to simulate the laser energy being applied to the whole weld joint simultaneously. This works well in T-style weld joints to get consistent, simultaneous displacement in the weld joint.
Line Beam
Line beam laser welding uses optics to spread the laser energy into a curtain that is passed over the part like a wide paintbrush. This works well for small intricate parts and larger flat area welding.
Masking
Masking uses a similar line beam curtain laser, but with a precision-cut mask over the part to shield the areas that don't require laser energy. This works well for ultra-precise welding with weld ribs less than 0.7 mm wide.

The Guide to Switch from Adhesive Bonding to Plastic Welding
In manufacturing and product assembly, choosing the proper joining method is critical to ensure the end product’s strength, durability, and efficiency. Adhesive bonding is a popular method for assembling plastic parts. But as product demand increases, the need for faster and more cost-effective joining methods arises. Plastic welding is a popular alternative to adhesive bonding that produces more durable, reliable, and cost-effective assemblies.
The 4 Reliable Methods for Controlling & Predicting Laser Weld Quality
Laser welding is a widely used method in plastic welding, particularly when precise and clean parts are required. But how can we be sure that the weld is of good quality? We utilize four reliable methods in our manufacturing process to ensure that we have achieved a high-quality laser weld. Through these methods, we can control and predict the quality of the weld, ultimately leading to better outcomes.
What is the difference between plastic welding and plastic staking?
If you’re an engineer, you may wonder what the difference is between plastic welding and plastic staking. Both of these methods join plastic together, but they use different techniques. Here, we’ll look at the differences between these methods so you can decide which is right for your project.
