Plastic welding? Don't get lost, we will explain.

Welding Thermoplastics

What are thermoplastics?

  • Thermoplastics are plastics or resins that will become soft when heated and begin to harden when cooled without changing the properties of the material through the process. Thermoplastics are easily recycled compared to thermosetting polymers because the polymer chain doesn’t degrade when melted down. 

 Common thermoplastics are: 

  • HDPE (High Density Polyethylene)
  • Polypropylene
  • PVC (Polyvinyl chloride)
  • ABS (Acrylonitrile Butadiene Styrene)
  • And many more…

Here at Affiliation we use hot air to soften the material and then use the correct plastic rod to fuse the materials together. This is not like ” hot gluing” this is “fusion.”

There are many plastics and they have a lot useful properties including chemical resistance, antimicrobial properties, UV stable material and some are safe to come into contact with food.

Before choosing a material ask yourself these useful questions:

  • What physical properties does this material need to have?
  • Will this material be subject to severe weather or temperature swings?
  • Is this material going to be under constant UV Light?
  • What potential chemicals will the material come into contact with?
  • Does this material need to be safe to come into contact with food?

All of these questions are viable and are necessary to find the correct plastic for your project.

Alex did awesome work welding some rock sliders on my truck. Worked with my schedule and made sure the job was done correctly. Welds look amazing and sliders are straight and solid! Will be going back to him for more custom work for the truck in the future!!
Was able to make modifications to my trailer same day! Great quality and respectful. Price was very reasonable as well. I recommend all the way. Appreciate the work!

Alex with Affiliation Welding worked directly for me for about 6 years before starting his own company. He proved himself over and over so I promoted him to head up my fabrication facility. He has done a great job for me as a welder both in metal and plastic on countless projects over the last many years. He always treated my customers, other employees and myself with utmost respect and honor. He is straight forward to work with and will tell you when a job is not a good fit. Few people could I recommend more highly to work with. He continues to do work for me on a consistent basis.
