Productieproces

Het product wordt vervaardigd met behulp van precisie-overmoldingtechnologie voor metaal:

  1. SUS304 Metal Forming
    Stainless steel components are precision machined or stamped.
  2. Oppervlaktebehandeling
    Surface cleaning and activation improve bonding performance.
  3. Fluorosilicone Injection Overmolding
    FVMQ material is injected onto the metal surface under controlled temperature and pressure.
  4. Uitharden en verlijmen
    The elastomer is thermally cured to form a durable bonded structure.
  5. Kwaliteitscontrole
    De afdichtingsprestaties, hechtingssterkte en maatnauwkeurigheid worden getest.
