I will design plastic injection mold tooling cad dfm report and moldflow simulation


About this gig
Getting a plastic part manufactured is expensive. If you just send a basic 3D model to a factory, they will usually reject it, or worse, you end up paying thousands for a steel mold that doesn't work right.
I am a tooling engineer. I don't just draw 3D shapes. I design the actual molds that factories use, and I run the flow simulations to prove the part will inject properly without warping, air traps, or sink marks.
Here is what I do:
- Full injection mold CAD (core, cavity, cooling lines, sliders)
- Moldflow analysis (testing the plastic flow before you pay for tooling)
- DFM checks (fixing your design so it can actually be molded)
- Standard CAD modeling and product design
- Prepping files for CNC machining and 3D printing
- 2D technical blueprints for the factory
I also design other types of production tooling. If you need molds for metal casting, ceramics, slip casting, or even custom silicone and chocolate molds, I can handle that too.
My job is to make sure your geometry actually works on the factory floor so you don't waste your manufacturing budget on bad tooling.
Send me a message with your 3D file, sketch, or idea before you place an order.

FAQ
What do I need to send you to get started?
Just send me the 3D CAD file of your product (preferably a STEP or IGES format). If you don't have a 3D file yet and only have sketches or reference photos, that is completely fine. Just message me first, and I can build the actual 3D product model for you before we start the mold design.
Will my manufacturer actually accept these mold files?
Yes. I don't just draw shapes; I engineer for the factory floor. I run DFM (Design for Manufacturing) checks to make sure your part has the correct draft angles, wall thickness, and no impossible undercuts so your factory can tool it without any issues or extra costs.
What exact files will I receive at the end of the project?
You will get the 3D solid CAD files for the complete mold assembly (usually in STEP or Parasolid X_T formats, which is exactly what CNC machines and toolmakers use). If your factory also requires 2D technical blueprints with dimensions, just let me know and I will provide those as PDFs.
