There are many factors that can affect the weldability of plastic materials. Lubricants, modifiers, resin grade and age can all affect weldability.

Amorphous vs. Semi-crystalline are two types of plastics that should bear full scrutiny and research early on in the product design phase, which will avoid costly pitfalls once you get to the manufacturing process.

The decision to use either Thermoset Plastics or Thermoplastics is not as simple as it seems when it comes to ultrasonic welding of plastic parts.
