An apparatus for molding a composite material comprising:
- a plurality of mold pieces that cooperate to form a mold having a mold cavity for molding a composite part, the plurality of mold pieces split along a plurality of part lines configured to reduce voiding, the plurality of part lines comprising part lines running from a plurality of voiding areas of the mold cavity to an outer surface of the mold and adapted to provide bleed lines for the plurality of voiding areas.
A molding method comprising:
- assembling a plurality of mold pieces into a mold having a mold cavity, the plurality of mold pieces split along a plurality of part lines configured to reduce voiding, the plurality of part lines comprising part lines running from a plurality of voiding areas of the mold cavity to an outer surface of the mold and adapted to provide bleed lines for the plurality of voiding areas;
- applying heat and pressure to the mold to cure a composite material disposed in the mold cavity into composite part;
- and
- during curing, bleeding gas bubbles from the voiding areas of the mold cavity via the bleed lines provided by the plurality of part lines.
