I will do mold flow analysis and dfm review for your plastic injection part
Juan Carlos
About this gig
Every mold mistake is paid for in steel. I help you find short shots, sink marks, weld lines, air traps and warpage before the mold is built.
I am a mold designer based in Mexico (US time zones) with 8 years of experience in injection mold design (CSWP Mold Tools). You get engineering judgment, not just colorful plots.
WHAT YOU GET
- A clear verdict: ready, ready with changes, or not ready
- Every result rated OK / Risk / Critical against an acceptance criterion
- Prioritized actions: what to change, where and why
- DFM checklist and result images in a PDF report you can share with your mold maker
LEVELS
BASIC: DFM + fill (fill time, pressure, weld lines, air traps)
STANDARD: + pack (sink marks, shrinkage, gate freeze, 2 gate options)
PREMIUM: + cooling and warpage, 2 scenarios and a 30-min results call
HOW IT WORKS
Send your STEP file, material grade and annual volume. Message me before ordering if your part is large, multi-cavity or a family mold.
CONFIDENTIALITY
Your files and results stay yours. I never publish or share them, and I delete them 30 days after delivery. NDA available on request.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

I'm Juan Carlos, a SOLIDWORKS engineer in Mexico (US time zones) with a background in injection mold design, CNC and plastics (CSWP Mold Tools). I help engineering teams in two ways. Automation: VBA/C# macros and add-ins for SolidWorks, Excel dashboards and SQL integrations that eliminate manual work. Plastic part validation: DFM review and injection simulation (fill, pack, cooling, warpage) to catch defects before the mold is built. I understand the production problem, not just the CAD side.
FAQ
Which file formats do you accept?
STEP is preferred; IGES, Parasolid (x_t) or native SOLIDWORKS files also work. One part per order. Assemblies, multi-cavity layouts and family molds need a custom offer.
Which software do you use?
SOLIDWORKS Plastics. You receive a PDF report with images and animations; native simulation files are not included.
I don't know the exact material grade. Is that a problem?
No. Tell me the material family and the application; I will propose a common commercial grade and state it in the report as an assumption.
Can you also fix my CAD or design the mold?
The report tells you exactly what to change and where. Editing your CAD or designing the mold is a separate custom offer.
Who owns the files and the report?
You do. Your CAD, the results and the report are yours. I never publish or share them and I delete your files 30 days after delivery. NDA available.
Does simulation guarantee a perfect part?
Simulation predicts; it does not replace mold trials. It reduces risk before steel is cut, and every assumption is written in the report.
What does a revision include?
Clarifications and a re-run for small changes to the same geometry and scenario. A new geometry or a new scenario after delivery is a new order.
