01
Resin Impregnation
Fiber bundles pass through a resin impregnator or wet out device, completely saturating with resin.
02
Preforming
Impregnated fiber bundles pass through “preformer” tools to squeeze out excess resin and align fibers into the desired shape.
03
Steel Die Polymerization
Impregnated fibers pass through a heated steel die where the resin cures and solidifies into a hardened polymer.
