Joining Method
Advantages
Disadvantages

Solvent Bonding

  • Good Aesthetics
  • Economic Assembly
  • Good for heat sensitive materials
  • Good Sealing and insulation
  • Possible entrapment of solvent in the joint
  • Can only be used when both materials are soluble to the same solvent
  • High Solvent Evaporation Time
  • Disassembly is not possible
  • Stress cracking/crazing

Ultrasonic Welding

  • Low Cycle Times
  • Low Capital Costs
  • Flexibility
  • Cleanliness
  • Bonding of dissimilar materials
  • Limited by the thickness of the materials
  • May Require specialized tooling
  • Noise Damage can be caused to the components or cold solder joints on some electronics (PCB’s)

Heat Staking

  • Low Cost
  • Repeatability
  • Strength of bond
  • Aesthetics
  • Ease of disassembly
  • Rebound can occur in some thermoplastics

Over Molding

  • Water resistant seal
  • Sound Absorption
  • Strength of Bond
  • Adhesion is limited to material choices
  • Expensive Tooling
  • Can not be disassembled
