About this gig

A CAD model can look perfect on screen and still create costly problems during mold manufacturing, ejection, cooling, or production. I help you identify those issues early and turn your plastic product into a practical injection mold and manufacturing ready CAD solution.

If you're unsure about your draft angles, wall thickness, undercuts, parting line, ejection, core/cavity or mold structure, send me your design. I'll review what matters and recommend the right approach before you commit to tooling.


What I offer:

  • Injection & plastic mold design
  • DFM & moldability review
  • Plastic part optimization
  • Core & cavity design
  • Parting-line development
  • Draft-angle checks
  • Wall-thickness optimization
  • Undercut identification
  • Sliders & lifters
  • Ejection system
  • Runner & gate concepts
  • Cooling-channel planning
  • Mold assembly
  • Mold components & inserts
  • Manufacturing drawings
  • STEP, STL, IGES & CAD files
  • Production-focused tooling documentation


Suitable for:

  • Product startups
  • Manufacturers
  • Engineers
  • Product designers
  • Inventors


Have a CAD file, sketch, or plastic part idea? Send it to me before ordering and let's determine what your project actually needs.
