Common Concerns

Dukane strives for the upmost in customer satisfaction, but as with any technology, sometimes concerns arise that must be addressed, such as:

  • Seeing a Flash
  • Misalignment of the welded assembly
  • Damage to internal components during welding
  • Welding together of internal components
  • Diaphragming


While the above issues are known to happen to welding products, they have simple explanations and solutions:

  • Seeing a flash – Reduce the size of the energy director, reduce interference, reduce weld parameter, reduce amplitude percentage, reduce trigger force, and increase part to part spacing.
  • Misalignment of the welded assembly – Add alignment, redesign fixture, add ribs or gussets, re-dimension parts, and tighten part tolerance.
  • Damage to internal components during welding – Radius sharp corners, reduce amplitude, decrease primary weld parameter, and ensure correct molding conditions.
  • Welding together of internal components – Be sure components are made of dissimilar resin, lubricate parts, and use higher frequency system.
  • Diaphragming – Reduce amplitude, reduce primary weld parameter, change gate placement, and check for proper horn to part fit.


The solutions outlined above should work in most cases. However, if they fail to resolve the issue, or if other problems arise, contact Rochester Industrial Services, Inc. for further repair assistance.
