One-Day Plastics Welding Course

"The Course was great. Exactly what my staff and I needed to fast track our understanding of the Plastic Welding technology. I am much more comfortable with my knowledge of the process and realizing my colleague was a bit of a natural at it helps me know we will be successful. Thanks to Matt for his patience teaching us and to Anthony for arranging the course for us." -Brandon Jewitt, General Manager, On the Water Designs

Why you Can’t Measure Air Temperature with a Laser IR Gun and a Simple, Effective Alternative
While Laser IR Thermometers are an extremely common tool, they are entirely ineffective for measuring the outlet temperature of an air heater. To understand why, we must first understand how this tool works. Laser IR Thermometers measure the surface temperature of an object by measuring the thermal energy emitted by the target. Knowing the amount of thermal energy discharged and the emissivity of an object’s surface, the objects temperature can be determined by the device.

​WELDPLAST vs. FUSION – What’s the difference between these Leister extrusion welders?
Leister manufactures two different series of extrusion welders: WELDPLAST and FUSION. Find out about their differences and advantages. ​

​How Screw Extruders Work 
In a screw-based extruder, the turning screw grinds up the welding rod as it passes through the barrel. Both the mechanical energy of the turning screw and heat introduced along the extrusion barrel plasticize the incoming material. The barrel can be heated either with hot air or with a coil heater. ​
