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

Tutorial: Evaluating your Plastic Welds
​It’s important to evaluate each plastic weld to ensure your final product is strong and resilient. Particularly when speed welding with a hand tool, small defects in a single weld can be magnified as beads are built up to the base material’s thickness. Several key indicators allow you to evaluate your welds without the need for destructive tests.  

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.
