Certified Plastic and Thermoplastic Welder: welding, fusion, and repair services

  • Leaking Plastic? Broken Pipe? Plastic welding can establish a waterproof or air-tight part-to-part seal on a plastic object.

  • Create State of the art dual containment systems.

  • Tank Repairs.

  • Custom fabrication and repair services. 

  • Custom design and fabrication of thermoplastic equipment parts and fixtures: PVC, CPVC, Polypropylene, PVDF Kynar, Teflon, HDPE.

  • Plastic welding for polyethylene chemical compound.

  • Containment trays for chemical overflow. 

What is Plastic Welding?

Plastic welding is the process of creating a molecular bond between two compatible thermoplastics. As a result, welding offers superior strength and reduces cycle times.


There are three main steps to any weld:

  1. Pressing

  2. Heating

  3. Cooling


Plastic welding processes are primarily differentiated by their heating methods. The application of force and allowances for cooling are mechanical considerations that vary from machine to machine within the general process category. Plastic welding is also be performed on thermoplastics or HDPE pipes for water supply. Thermoplastics are often associated with legos, 3D printing, and plastic containers.


Industrial mechanics also seek to buy shields, face shields, and Dremel's to do smaller projects, but companies like ours tackle Industrial size projects at the highest level.

Butt-Fusion of Polypropylene Pipe

Butt-Fusion, also known as heat fusion,  is a process used to join thermoplastics such as Aquatherm’s polypropylene together. Rather than using glue, solder, or a mechanical connection and gasket, heat fusion physically turns the two pieces of plastic into one piece. The process is similar to welding but doesn’t require a filler material, nor does the fusion process weaken the material at the point of connection. Heat fusion makes the connection at least as strong as the pipe itself. In some cases, the connection is even more vital. 

Heat fusion works by returning the connection point to a melted state the way it was during production. This allows the polypropylene chains to join together as the connection cools for a permanent bond as if they were manufactured as one piece. This prevents any sort of chemical or physical weakness at the point of connection and results in a much lower instance of leaks or failures.
