FAQs
Plastic welding is a process used to join thermoplastic parts using controlled heat and pressure. Depending on the technique, energy sources such as lasers, friction, hot gas, or ultrasonic vibrations are used to melt and fuse surfaces. The result is a strong, permanent bond without adhesives or mechanical fasteners.
Plastic welding is widely used in automotive, healthcare, consumer electronics, packaging, aerospace, and industrial automation. Its ability to produce clean, precision welds makes it ideal for applications that demand reliability, tight tolerances, and visual perfection.
Common methods include laser welding, hot plate welding, ultrasonic welding, and vibration welding. Laser plastic welding, as promoted by Dynotech, stands out for its accuracy, cleanliness, and automation-friendly nature—especially in high-value production settings.
Laser plastic welding is a non-contact process that uses a focused beam to deliver heat only to specific areas. This allows for minimal material distortion, cleaner joints, and high process control. Unlike hot plate or ultrasonic methods, it is better suited for sensitive assemblies and micro-components.
Yes. Dynotech offers fully automatable welding solutions. Our systems are designed to integrate into existing production lines or as standalone modular stations. Automation enhances productivity, consistency, and traceability, making it ideal for high-throughput industries.
Absolutely. Plastic welding eliminates the need for glues, solvents, or additional materials—reducing chemical waste. It also minimises scrap rates by producing precise, repeatable welds. This aligns well with sustainable manufacturing goals and green initiatives.
