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

Choosing the Right Tool for your next Plastic Welding Project
Broadly, there are two types of hot air plastic welding tools: manual tools and extrusion welders. Manual tools are ideal for very small fabrication work, detailed projects, and repair work. Extrusion welders are suited for larger fabrication projects such as tanks, chutes, liners, and piping. 

Identifying Plastics for Fabrication and Repair
It's important to identify the plastic you're welding as only like plastics can be joined. The simplest way is by performing a burn test. Learn what properties to look for and how they can tell you the plastic type of your material.

Water Management at "La Casa de Suiza"
Mexico, a country stretching from Guatemala's subtropical climes in the south up to the dry Arizona desert in the north, is continuously confronted with water shortages as well as polluted subterranean and surface waters. Consequently, wastewater treatment has the two-fold objective of preventing the contamination of water bodies, while at the same time using waste water to generate purified water, which can be used for irrigation and/or sanitary purposes. Eight years ago, the company Think TIM brought European technology to Mexico to carry out this task on a small scale at domestic level, or to treat water in small establishments such as hotels, businesses, or residential developments.​

​Extrusion Welding PVC: Why You Need a Specialized Tool
When PVC is melted or burned, it emits hydrogen chloride (HCl) fumes. At room temperature HCl is a colorless gas, although it will form white fumes of hydrochloric acid upon contact with atmospheric water vapor. When welding PVC the work area should be well ventilated, either naturally or through a forced air system.

​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.

​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. ​
