I will engineer your product for prototyping and injection molding


About this gig
ABOUT MY GIG
Designing a part that looks right on screen is easy designing one that molds correctly, every time, takes real engineering.
I'm a product design engineer specializing in engineering parts for prototyping and injection molding. I help startups and product companies avoid the #1 mistake in product development: sending a non-manufacturable to the mold maker.
What I deliver:
- Design for Manufacturing (DFM) analysis for injection molding
- Draft angle, wall thickness, and rib/boss optimization
- Mold ready 3D CAD models and 2D drawings
- Prototype ready designs (3D printing before tooling)
- Material selection guidance and cost reduction recommendations
I work with clients developing consumer products, enclosures, and mechanical components who need a design that's ready for real production not just a concept. Catching design issues before tooling saves thousands of dollars in mold rework.
Having supported clients across the US, UK, and Europe, I bring a practical, manufacturing first approach to every project, with clear documentation your mold maker can use immediately.

FAQ
Can you design my part from scratch, or only review existing designs?
Both I can design new parts or optimize your existing CAD for moldability.
Do you work with a specific molder, or can I use my own?
I prepare mold ready files you can send to any injection molder or tooling shop.
What if my part has undercuts or complex geometry?
I'll review the geometry and recommend design changes or slide/lifter solutions if needed.
Do you provide a prototype before tooling?
Yes I can prepare a 3D printable version to validate fit/function before you invest in a mold.
What CAD software do you use?
SolidWorks and Fusion 360, delivered in STEP/native formats.
