Plastics Welding

We strive to improve the safety, efficiency, and lifespan of welded thermoplastic components on behalf of our customers. Our specialists in the welding of semi-finished plastic materials and component pieces are highly skilled and professionally qualified members of our plastic fabrication team.

Plastic welding applications that require solid bonded plastic joints include for example machine guards, chemical industry equipment, and industrial tanks. Our complex, welded plastic assemblies come from industries such as medical, aerospace, and electronics.

Our customers rely on our expertise and know-how to select the right plastics type and the appropriate plastics welding techniques ideally suited to the needs of their applications. Our experience allows preventing situations in which thermoplastic welds may be forced to malfunction or underperform.

High levels of consistency and safety requirements.

In addition to the experience and skills of our plastic welders, carefully considered ergonomics is important to upholding our high quality and safety levels. We are certified by ISO 9001:2015 and aim to continuously improve our plastic welding services, streamline our practices, and reduce costs.

Methods of Plastics welding:


Welding with Hot Gas (Air):

Welding using hot gas (or hot air) is a process that uses heat. Thermoplastic sheet parts and the components to be joined are positioned together with a plastic welding filler rod that must be the same or equivalent material in the joint region in a V-butt or T-butt slice. To form the weld, a hot gas (or air) jet from a welder gun softens and fuses the pieces together with the rod.

Hot gas welding uses are various applications, including maintenance jobs, plastic storage tanks, plastic tubes, plastic ventilation ducting, heat exchangers, safety guards, plastic panels, and more. Some of the advantages of hot air welding include:

  • Particle-free, composite components thermal welding.
  • Suitable for the welding of a wide variety of films and thermoplastics.
  • No mechanical tension on the components processed.
  • High quality welded joints that are air and water pressure resistant to help improve product lifespan.
  • Ideal for making new goods, restoring or enhancing performance with the resultant bond stronger than the initial components used in manufacturing.
  • It is possible to weld long and continuous panels, making them suitable for larger goods.
  • A manual procedure that depends heavily on the ability and experience of qualified welders.
  • Equipment is readily accessible and encourages versatility in the ergonomics of the office.
  • The welding wound is applied to the interior of the plastic pieces which protects the aesthetic quality of the exterior layers from being harmed.

Welding with Ultrasonic:

In order to produce frictional heat in the joint or weld field, ultrasonic welding requires high-frequency energy converted into mechanical activity (vibrations). The plastic is then melted into a chemical bond. The heat strength depends on the polymer loss modulus, the frequency (typically 20, 30 or 40 kHz), and the ultrasonic vibration amplitude.

Ultrasonic plastics welding is a common option for product assembly in industries including automobile, aerospace, medical, communications, and consumer appliances due to very short welding times, and the consistency of final visual appearances. The advantages of ultrasonic plastics welding include:

  • Particle-free, composite components thermal welding.
  • Suitable for the welding of a wide variety of films and thermoplastics.
  • No mechanical tension on the components processed.
  • A smooth finish of the weld area and consistent joint consistency.
  • With sophisticated control and monitoring features, the equipment is new and advanced. For validation purposes, process comparison data is available.
  • Suitable for smaller, lighter sections welding.
  • The creation of instruments is required.


Choosing the correct materials and process, and setting the welding parameters of strain, temperature and time precisely is critical. Thus, at the beginning of each project, along with the probability and potential rate at which fracture, fatigue, and/or stress corrosion can occur in a given end-use environment, we examine the interdependent factors of weld power, component geometry, speed and expense.

We provide a range of high-grade thermoplastic boards, square cylinders, U-profiles and welding rods to ensure that the application's quality, design and performance requirements can be met.

Materials that are suitable  for plastic welding include:

  • Polyethylene

  • Polycarbonate

  • PETG polyester

  • Polypropylene

  • PVC

  • ABS
