Heat Form Technology on TPV and PP materials

Glass run:  Eliminates over molding corners  and offers a continuous flow for a higher quality part at a lower cost.

Upper retainers with and without a carrier:  Enables you to achieve more complex shapes at a lower cost (cannot be achieved with traditional stretch bending).

To manage the thermal expansion of PP/TPV, a lance carrier was added to stabilize this part and to give it added strength, The Upper Retainer was heat formed at one end because of “90” deg bend requirement. The ends were overmolded.

Heat Form Technology on TPV and PP materials

Outer belt:  Enables you to achieve more complex shapes at a lower cost (cannot be achieved with traditional stretch bending).

  • This technology was used on this Outer Belt because of the sharp angle change
  • To manage the thermal expansion of PP/TPV parts, an end cap is overmolded and has a tapered shape that allows the outer belt to grow and shrink without of seeing gaps

Roof ditch molding with and without a carrier:  Enables you to  achieve more complex shapes at a lower cost (cannot be achieved with traditional stretch bending

To manage the thermal expansion of a PP/TPV, a wire core was added to stabilize this part. The Roof Ditch was heat formed at one end because of its “S” shape with a down bend, than trimmed and over molded with end caps
