About this gig

Struggling to convert your product idea into a moldable dsign?

Worried your part won't survive the injection molding process?


I'm a mechanical design engineer with 8+ years specializing in plastic part design and injection mold engineering. I've helped 30+ manufacturers avoid costly mold rework by getting DFM right the first time.


WHAT YOU'LL GET:

  • Precise 3D CAD model
  • Mold de-sign (core & cavity)
  • DFM analysis report
  • Draft angle & wall thickness check
  • Manufacturing-ready files (STEP, STL, IGES)


SCOPE OF WORK:

  • Product concept review & analysis
  • 3D CAD modeling with proper tolerances
  • Draft angles, wall thickness optimization
  • Parting line & gate location design
  • Core/cavity mold design
  • DFM report to prevent production issues
  • File preparation for moldmakers


I focus on designs that minimize tooling costs, reduce cycle time, and eliminate defects like warping, sink marks, and short shotssaving you thousands in mold correction fees.


Ready to get your product mold-ready? Message me now with your part details, and let's build a de sign that manufactures perfectly the first time!
