RAPID PROTOTYPING WITH COMPOSITE TOOLING
MOLD CAVITIES

When you need 1-500 parts that need to exhibit characteristics unique to injection molded plastic, a composite tooling prototype mold by OAR Moldworks may be your answer.


Characteristics unique to a composite tooling mold:
  • Cavity/core geometry is CNC machined using your exact solid model, not cast - providing for true part geometry and shrinkage factors, no bench work necessary
  • Molds produced with composite tooling cavities and cores last longer than SLA molds and produce truer part geometry
  • Fast turnaround, less than the time of a steel mold
  • Roughly the cost of a steel mold
When a composite tooling mold by OAR Moldworks may be appropriate:
  • You need a living hinge
  • Your part requires slides or cams
  • You need the performance of injection molded plastic
  • You need color changes
When an aluminum or steel mold may be more appropriate:
  • When your part has thin, deep ribs or bosses
  • When your part requires delicate core/cavity work
  • When your specified plastic requires a heated or chilled mold
  • You’ve specified a heavily filled plastic

To do either type of mold you need a native Pro/E or Unigraphics file, or a 3-D database in IGES format, and you need to provide the plastic and colorant.
