3D MODELING INJECTION MOLDING SHELF PARTS

image (3).jpg

A product designer came to us to 3D model via parametric CAD modeling a shelf bracket for injection molding. He provided us with a rough concept he made inside TinkerCAD that he exported as an STL file.

First, we made 2D sketches on top of his 3D mesh to capture the key dimensions & also add the finer features he couldn't accomplish in TinkerCAD.

Once the information is captured in 2D, the object could be easily brought into 3D by extruding up the sketch with a 3-degree draft angle for injection molding.

Here was the finished part 3D modeled parametrically in order to produce a clean manufacturable STEP file (which he will email to various manufacturers to get manufacturing quotes).

As you can see, the STL file produced in TinkerCAD wasn't sufficient for manufacturing because it was just a set of triangles (mesh).

A cover plate was also 3D modeled parametrically with the appropriate draft angles, ribbings, & other design features appropriate for injection molding.

Here is a cross-sectional view of how the various parts will fit.

Multiple screenshots were provided to communicate the completion of the various key features of this project.

All 3D modeling comes with 1 round of free revision. And the client decided to implement some new features.

As always, plenty of screenshots will be provided to minimize any ambiguity to zero.


Everything looks good & the client can sleep well at night knowing that the mold will be produced faithfully to his design!
