I will develop core and cavity mold toolings and 3d mechanical cad in autodesk inventor
Cindax
About this gig
Mechanical and Industrial Design Engineer with 5+ years experience engineering core and cavity mold toolings and 3d mechanical cad in autodesk inventor. I specialize in plastic tooling layouts, core/cavity splits, and production CAD geometry built for injection molding factories.
Services I Offer:
- Core and cavity separation with parting line creation, shut-off surfaces, and draft validation
- Plastic part design optimization for uniform wall thickness, rib structures, and shrinkage rates
- Multi-piece mold base assemblies with ejection pins, cooling channels, runner systems
- Detailed 2D technical drawings for mold machining with GD&T and ejector layout specs
- Moldflow analysis prep, draft reviews, and undercut identification for tooling feasibility
Tools I Use:
- Autodesk Inventor (Mold Workspace)
- Moldflow
- SolidWorks
- AutoCAD
File Formats Delivered:
- Native CAD: IPT, IAM, IDW
- Manufacturing: STEP, IGES, X_T
- Visuals: STL, PDF, DWG
Why Work With Me?
- Unlimited Revisions until complete tooling alignment
- Direct factory-ready DFM and shrinkage allowance calculations
- Error-free core/cavity splits for seamless CNC EDM machining
Please message me to discuss your project!

Mechanical & Industrial Design Engineer focused on turning physical product concepts into production-ready CAD models. I ensure every design meets precise manufacturing constraints, factory tolerances, structural integrity requirements.
Core skills: • 3D CAD modeling • Mechanical part design • Sheet metal enclosures • Plastic injection mold prep • Assembly modeling • Reverse engineering • CNC manufacturing drawings • 3D printing prep (STL).
I use SolidWorks, Fusion 360, Autodesk Inventor daily. Message me with your project details before ordering.
FAQ
What details are required to start a core and cavity mold tooling design in Autodesk Inventor?
I need your 3D CAD model or component sketch, targeted plastic resin (e.g., ABS, PP, PC), shrinkage rate expectations, and press size or tooling specs if available.
How do you establish proper parting lines and shut-off surfaces for mold toolings?
I analyze part geometry in Autodesk Inventor, locate natural draft split lines, apply necessary shut-off surfaces, and check for negative draft or undercut areas before splitting core and cavity inserts.
Do you calculate resin shrinkage allowances directly into the core and cavity CAD models?
Yes. I factor material-specific volumetric shrinkage percentages directly into the Inventor mold core and cavity models so molded parts cool to nominal print dimensions.
Which software applications are used to design the mold core, cavity, and tooling assemblies?
I use Autodesk Inventor Tooling & Mold Design workspace for core/cavity generation, supplemented by SolidWorks, Moldflow, and AutoCAD for detailed tooling drafting.
Can you handle complex plastic parts with side-actions or lifters for undercuts?
Yes. I design side-action slider blocks, angle pins, and mechanical lifter assemblies in Autodesk Inventor to release internal or external undercut geometry cleanly.
What file formats will I receive for CNC machining and EDM electrode creation?
You will receive editable native Autodesk Inventor files (IPT, IAM, IDW), universal neutral CAD files (STEP, IGES, X_T) for CNC toolpaths, and 2D engineering PDFs.
Do your 2D mold drawings include GD&T callouts and ejection pin locations?
Yes. 2D technical drawings include complete plate dimensions, ejector pin hole coordinates, water line layouts, surface finish specs, and GD&T tolerancing per ISO or ASME standards.
Will the core and cavity files work directly with my mold maker's CNC machine shop?
Yes. The geometry is generated as clean, closed solid B-rep CAD files ready for 3-axis/5-axis CNC machining, wire EDM cutting, and sinker EDM electrode extraction.
Do you offer revisions if my mold manufacturer requests small modifications?
Yes, I offer Unlimited Revisions. If your toolmaker asks for adjusted draft angles, modified runner gates, or altered ejector positions, I will update all CAD files accordingly.
Should I message you before placing a direct order?
Yes, please message me first. Reviewing your plastic part geometry beforehand ensures we confirm draft feasibility and choose the exact package tier for your mold tooling needs.
