I will create automotive abs plastic component injection mold dfm cad catia solidworks
Julien Mathias
About this gig
Automotive plastics live in a punishing world. Heat cycling, vibration, UV, snap fit fatigue and tooling that costs more than a car. I design ABS and ABS blend components in CATIA and SolidWorks with full DFM applied from the first feature, so your tool maker quotes with confidence.
What I design
- Automotive ABS plastic components
- Interior trim panels and bezels
- Dashboard and console parts
- Door cards, pillars and scuff plates
- Exterior grilles, covers and spoilers
- Clip, snap fit and boss features
- Heat stake and screw fixing details
- Ribs, gussets and reinforcement geometry
- Living hinges and flexible features
- Draft angles and parting line layout
- Undercut, slide and lifter planning
- Uniform wall thickness and sink prevention
What you get
- Mold ready 3D model in STEP
- Native CATPart or SolidWorks source
- Print ready STL for prototype validation
- Dimensioned PDF engineering drawings
- DFM report on draft, thickness and undercuts
- Parting line and ejection direction defined
- Revisions based on your package
Send your sketch, scan or existing CAD, mounting points, material grade, environment and production volume. Message me first so I can review the part and confirm the right package.
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.

Tooling costs more than most cars, so I take draft angles very seriously.
I engineer plastic housings for medical devices, automotive ABS components, lithium battery packs, and countertop kitchen appliances, using SolidWorks, Creo, and CATIA with full DFM from the first feature.
Uniform walls. No hidden undercuts. Defined parting lines. Honest notes on what will and will not mold cleanly. You get a prototype STL to test, then a mold ready STEP your tool maker will thank you for.
Send your components and requirements. Let's build it properly.
FAQ
What do you need to start?
Sketches, reference images, scan data or existing CAD, mating part dimensions, material grade, operating temperature, mounting method and production volume.
Which materials do you design for?
ABS, ABS PC, PP, TPO, PA6 GF and other common automotive grades. Tell me the grade and I apply the right shrinkage, draft and thickness.
Do you apply draft angles and wall thickness rules?
Yes, every surface gets correct draft for your material and texture, with uniform walls to prevent sink marks and warping.
Can you design snap fits and clips?
Yes, including standard automotive clip interfaces, heat stakes, screw bosses and retention features.
Can you work from a physical sample or scan?
Yes, send a 3D scan, photos with measurements or a dimension list and I will rebuild it as clean production CAD.
Do you handle undercuts and slides?
Yes, I identify undercuts and plan slide or lifter actions, or redesign geometry to remove them where possible.
Do you provide FEA or crash simulation?
No, this service covers CAD and DFM only. Structural, thermal and crash validation must be done by a qualified analyst.
Do you design the mold tool?
Core and cavity split review is available as an extra. Full tool design with cooling and ejection is a separate service.
Which formats do you deliver?
STEP, STP, IGES, CATPart, CATProduct, SLDPRT, X_T, STL, DXF and PDF.
