Save Money with Axenics’ Plastic Welding Services

With more than 30 years of experience, Axenics offers clean and repeatable plastic pipe welding services which mirror our welding capabilities for metals.

Our certified welders are capable of welding polymer-based materials including:

  • Polytetrafluoroethylene (PTFE/FPA)
  • Polyvinyl Chloride (PVC)
  • Chlorinated Polyvinyl Chloride (CPVC)
  • Polypropylene (PP)
  • High density polyethylene (HDPE)
  • Polyvinylidene fluoride (PVDF)

There aren’t many organizations with the skills necessary to bend and weld Polytetrafluoroethylene (PTFE).

Plastic pipe welding is commonly used to create custom manifolds and assemblies. Welding allows for the joining of two units as an alternative to the use of bulky or expensive fittings, saving time, space and money. Plastic pipe welding, when done with precision, can be used to produce strong and complex systems that meet our customers’ exact project requirements.

Axenics welds plastic piping using heat fusion, butt welding or solvents. Our thermoplastic pipe welding process involves the joining of two polymer-based units heat to create the strongest possible bond. The two plastic units to be joined are heated simultaneously and pressed together. Once the pieces have cooled, they form a permanent bond.

Benefits of Plastic Pipe Welding with Axenics

Our highly skilled and trained welders have the ability to perform ¼-inch pipe-to-pipe welds.  Axenics uses a custom-built machine capable of repeating a simple welding process automatically to save our customers both time and money.

Plastic components are frequently used in applications where metal components could corrode or decay due to the gas or liquids being transported. We see this often in the medical device, chemical manufacturing, semiconductor and life sciences industries. Companies in each of these industries face complex challenges that can be solved by plastic pipe bending and welding.

Perhaps even more so than fabricating with metals, plastic manufacturing requires a high level of skill and expertise to ensure the integrity of the bends and welds. Our qualified technicians can weld and bend plastics to fit almost any shape and/or space requirements without the need for adding multiple joints and fixtures.

Plastic Pipe Welding Process

There are three main steps to plastic welding:

Surface Preparation

First, the technician will check each plastic component for defects. The plastic components are often cleaned and/or abraded in order to aid in the welding process.

Welding Applications

Plastic pipe welding can be performed in several ways. It is often performed with the use of heat, though it can also be done through use of a chemical solvent, depending on the type of plastics being joined. PVC, for example, is sometimes welded with the use of dichloromethane. This chemical temporarily dissolves the chemical bond in PVC, which allows the plastic component to be changed before the bond is restored.

Using heat, the plastic can be softened to make it easier to work with. Heat can be applied by using steam, hot gas, a welding rod, a laser or a hot plate. While the plastic components are soft, they are put into a vise, where pressure is applied to the pieces, causing the edges to bond together. Consistent pressure must be applied to ensure the quality and integrity of the weld.


Once the welding process is complete, the newly formed product is left to cool. Pressure may continue to be applied during the cooling process to help the product retain its shape. If pressure is not applied during cooling, the shape of the product is sometimes altered from material shrinkage.
