Insulation molding technology

[Weld line measures, High transfer technology]

This technology of thermal insulation layer allows resin to flow fast through the resin fluidized part before loosing heat for high transfer property.

Weld line measures, High transfer technology

[Applications]

  • Micro structure high transfer
  • Weld line measures

[Application product]

Application product

Micro structure (height 10µm)
Case study of transfer improvement
