Ethan
About this gig
Mechanical design engineer with 7+ years of industrial experience delivering tooling-ready CAD architectures. I provide plastic injection tooling design alongside mold flow analysis to resolve manufacturing defects before cutting steel. My work centers on building precise 3D mold assemblies and delivering clean STL file packages for physical evaluation.
Services I Offer:
- Mold flow simulation for filling, weld lines, air traps, volumetric shrinkage
- Injection mold cavity, core, and slider mechanical design
- Gate location optimization and balanced runner channel modeling
- Cooling line circuit design for cycle time reduction
- Core/cavity split and STL file preparation for rapid tooling
Tools I Use:
- Autodesk Moldflow, SolidWorks Plastics, SolidWorks CAD, Fusion 360
- File Formats Delivered: STEP, STL, X_T, IGES, SLDPRT, PDF Report
Why Work With Me?
- Unlimited Revisions
- Real-world moldmaking parameters based on resin viscosity profiles
- Direct alignment with CNC machining tolerances to avoid tooling rework
Please message me to discuss your project requirements before placing a direct order.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

FAQ
What specific CAD or resin details are required to run a mold flow analysis?
I require your 3D CAD part file in STEP or SLDPRT format, along with the specific plastic resin grade (e.g., Sabic Cycolac ABS). If you have target injection press specs, sharing those helps tune pressure limits.
What defects are identified during the mold flow simulation?
The simulation maps filling behavior, injection pressure, volumetric shrinkage, air trap locations, weld line formation, and predicted part warpage across thermal gradients.
How does running a flow simulation reduce mold manufacturing costs?
Identifying high injection pressures or bad weld line locations in software allows us to move gates or tweak wall thickness before cutting metal, preventing expensive tool modifications.
Which simulation software do you use for analysis?
I utilize Autodesk Moldflow and SolidWorks Plastics using validated material property databases for thermoplastic resins.
Can you design cooling channels for complex tool blocks?
Yes. I model optimized cooling circuits—including baffles, bubblers, and conformal channels—to establish uniform heat dissipation and minimize cycle times.
Do you balance runner systems for multi-cavity tooling setups?
Yes. I calculate and adjust runner diameters to ensure uniform pressure distribution and balanced volumetric filling across all mold cavities simultaneously.
