FAQ
What is DFM for injection molding?
DFM helps identify design issues that could affect molding, tooling, production cost, quality, or part release.
Can you modify my existing plastic CAD model?
Yes. I can review and modify existing CAD geometry based on injection molding and manufacturing requirements.
Can you check draft angles and undercuts?
Yes. I can evaluate draft, undercuts, wall thickness, parting-line considerations, and other moldability factors.
Can you design the plastic part and mold together?
Yes. Depending on the package, I can develop the plastic part while considering core, cavity, parting-line, and tooling requirements.
What files can I send?
You can send STEP, STP, IGES, STL, SLDPRT, DWG, PDF, sketches, dimensions, or suitable reference files.
Can you prepare the design for manufacturing?
Yes. I can optimize the CAD model with injection molding and manufacturing considerations in mind.
Do you work with complex plastic parts?
Yes. Complex geometry can be reviewed for undercuts, draft, parting lines, core/cavity requirements, and other tooling considerations.
