PLASTIC WELDING
Welding stronger bonds.
On behalf of our customers, ICL Tech aims to optimise the safety, performance and lifetime of welded thermoplastics parts. Highly experienced and fully trained members of our plastic fabrication team are specialists in welding semi-finished plastic materials and component parts.
Plastic welding applications frequently include machine guards, chemical industry devices and industrial tanks that require impervious, strong bonded joints. Our smaller more complex plastic welded assemblies originate from sectors including medical, automotive and electronics.
ICL Tech’s customers rely upon our knowledge and know-how to select the plastics and welding methods best suited to their applications’ needs. For those still at the design stage, our expertise helps to avoid scenarios in which thermoplastic welds can be expected to fail, or underperform.
High standards in quality and safety.
The carefully thought out ergonomics of ICL Tech’s workplace, alongside the skills and knowledge of our plastic welders is key to maintaining our high standards in quality and safety. We are ISO 9001:2015 accredited and seek to continually improve our plastic welding services , streamline our operations, and reduce costs.
Welding Methods
Hot Gas (Air) Welding:
Hot gas (or hot air) welding, is a technique that uses heat. Sheet sections of thermoplastics – the parts to be joined - are placed in a V-butt or T-butt position with a consumable plastic welding filler rod that must be the same or similar material at the joint area. A jet of hot gas (or air) from a welder gun softens and fuses together the parts with the rod to form the weld.
Applications for hot gas welding are many and varied, and include repair works, containment tanks, vessels, ventilation ducting, heat exchangers, protective guards, panels and more.
- Particle-free, thermal welding of plastic parts.
- Suitable for welding a wide range of thermoplastics and films.
- No mechanical stress on the processed parts.
- High strength welded joints that are resistant to air and water pressure, helping to maximize the longevity of products.
- Ideal for fabricating new products, repairing, or improving functionality with the resulting bond stronger than the original materials used in fabrication.
- Long and continuous panels can be welded making it ideal for larger products.
- A manual operation that relies heavily on the skills and knowledge of trained welders.
- Equipment is easily portable, and supports flexibility in workplace ergonomics.
- The weld wound is applied to the inside of the plastic parts and this prevent damaging the cosmetic appearance of the external layers.
Ultrasonic Welding:
Ultrasonic welding involves converting high frequency energy into a mechanical motion (vibrations) to create frictional heat in the joint or weld area. This melts the plastic to from a molecular bond. The heat intensity depends on the loss modulus of the polymer, the frequency (typically 20, 30 or 40 kHz), and amplitude of the ultrasonic vibrations.
Due to very low weld times, and the quality of end visual appearances, ultrasonic welding is a popular choice for component assembly in industries including automotive, aerospace, medical, electronics, and consumer appliances.
- Rapid weld time (typically < 1 second).
- High strength, cohesive, form-fit joints.
- Almost all plastic materials can be welded ultrasonically. However, the size of the application can be limited by how easy to weld the plastic is – the easier it is to weld, the larger the size, and vice versa.
- A clean weld area finish with consistent joint quality.
- Equipment is modern and advanced with sophisticated control and monitoring features – process reference data is available for validation purposes.
- Suitable for welding smaller, thinner parts.
- Tool design is required.
Materials
It’s of crucial importance to select the right materials and method, and accurately set the welding parameters of pressure, temperature and time. So at the outset of each project, we analyse the interdependent factors of weld strength, part geometry, speed and cost alongside the likelihood and potential rate at which fracture, fatigue, and /or stress corrosion may occur in a given end-use environment.
ICL Tech offers a variety of quality thermoplastics sheet, square tubes, U-profiles and welding rods to ensure we can meet the quality, design and performance criteria of your application. Suitable materials include:
• Polyethylene
• Polycarbonate
• Polyester PETG
• Polypropylene
• PVC
• ABS
