Ultrasonic Welding Plastic Parts

When you need to join two injection-molded plastic parts, it’s highly likely that ultrasonic welding is your best choice. It takes seconds and results in high-performing, long-lasting products.

Take your plastics parts to the next level with high-quality ultrasonic welding capabilities from Bruin Manufacturing. A leading injection-molded plastic fabricator, we offer our clients value-added ultrasonic welding to simplify production, eliminate downtime and further reduce an upper-level item’s total build cost.

Ultrasonic welding is an industrial technique in which high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. Unlike friction or vibration welding processes, where one of the two parts is moved to create friction, ultrasonic welding produces friction from acoustic energy that generates heat and joins the two pieces together at a molecular level.

Ultrasonic Welding Benefits

The bonds our highly skilled technicians produce with ultrasonic welding are clean, smooth and robust. The process does not leave behind beads of rough and porous filler material that can cause leaks, disturb fluid flow paths and foster bacteria growth. Also, there are no connective bolts, nails, soldering materials, and adhesives. Additional benefits of ultrasonic welding include:

  • Saves time
  • Reduces production costs
  • Produces a high-quality bond
  • Forms a tight seal

Ultrasonic Welding Applications

Ultrasonic welding is commonly used in plastics fabrication, especially for joining dissimilar materials such as hard and soft materials. Applications that can benefit from ultrasonic welding include:

Ultrasonic welding is a quick, clean, and cost-effective way to bond plastic parts. At Bruin Manufacturing, we are committed to quality and dedicated to our customers.
