• Shedding New Light On Tiny Packages
  of adhesives. Parts are clamped firmly together during the process to boost heat conduction and further encourage local melting at the joint. Welds can be shaped as a point, line, or an area. Part geometry and the clamping fixture limit the length of a weld line. Line width can be varied from several...

  sharp melting point; that is, they do not soften gradually with an increase in temperature. Rather, they remain hard until a given quantity of heat is absorbed, then change rapidly into a low-viscosity liquid. Reinforcement of crystalline polymers with fibers of glass or other materials improves...
