FAQ
Can you design a plastic part from a sketch or existing CAD?
Yes. Send a sketch, STEP file, photos with dimensions or your current SolidWorks model and I will design or rework it for injection molding.
What does the DFM report cover?
Draft angles, wall thickness, ribs, bosses, undercuts and snap fits, plus risks like sink marks and warpage, with clear fixes marked in the model.
Do you design the full mold or run Moldflow?
No. I design the plastic part and the core and cavity split with parting line. Full mold base design and Moldflow simulation are not included.
Which files will I receive?
STEP, IGES and STL in every package. Standard and Premium add SolidWorks SLDPRT and SLDASM source files and PDF drawings.
Can you fix a part my manufacturer rejected?
Yes. Send the supplier feedback with your part file and I will redesign it to solve the moldability issues, keeping fit and function.
