What you'll learn

  • Understand the fundamentals of plastic materials used in automotive interior trims, including their properties, selection criteria, and applications.
  • Identify and analyze common automotive plastic interior parts such as door panels, instrument panels, pillars, and consoles
  • Gain proficiency in CATIA V5 surfacing techniques for designing and developing plastic interior trim components
  • Apply design principles, engineering standards, and manufacturing considerations (injection molding, draft, ribs, bosses, etc.) in plastic trim development.

Course content

7 sections • 112 lectures • 16h 16m total length
  • Introduction2:16
  • Introduction to Plastics2:27

    Explore how plastics form from crude oil to polymers through extraction, cracking, and polymerization, with hydrocarbons becoming monomers like ethylene, propylene, and butadiene to polymerize into resins.

  • Introduction to Plastics -22:08

    Learn how plastic resins are compounded with colorants, UV stabilizers, flame retardants, and fillers like glass fiber or talc to tailor strength, appearance, and cost, and distinguish thermoplastics from thermosets.

  • ABS5:42

    Explore ABS and plastics, distinguishing amorphous and semi-crystalline types, and outline ABS properties and automotive interior and exterior trim applications.

  • POLY CARBONATE3:28
  • Polyvinyl chloride (PVC)3:19

    Explore vinyl chloride, PVC, a dense, amorphous thermoplastic used in ducts and pipes. Understand its stiffness, heat tolerance, chemical resistance, and easy processing.

  • Polyethylene (PE)3:54
  • Polypropylene (PP)4:05

    Explore polypropylene's lightweight, cost-efficient role in automotive trims, its semi-crystalline structure, stiffness, fatigue resistance, heat tolerance, and how it suits bumpers and dashboard panels.

  • Material Table0:47

    Divide materials into three amorphous and three semicrystalline structures, provide a downloadable pdf table, and urge design engineers to print and memorize these values for interviews.

  • Shrinkage8:54

    Explore shrinkage in injection molding, how molten plastics cool and contract, and why material type (crystalline vs amorphous) drives final part size and mold design decisions.

  • Wall Thickness8:22

    Follow seven rules for plastic parts, emphasizing uniform wall thickness to prevent warpage and sink marks, core out for weight reduction, and draft, material selection, parting line, and avoiding undercuts.

  • Draft Angle5:56

    Apply draft angles to mold features to ease ejection. Keep draft angles between 0.5 and 3 degrees and maintain rib thickness at about 50 to 60 percent of wall thickness.

  • Coring3:07
  • Material Selection6:34

    Explore material selection for injection molded plastics, balancing cost, functionality, assembly, temperature resistance, strength, and regulations. Review common thermoplastics like ABS, PVC, PE, PP, and PA and their applications.

  • Parting Line4:00

    Place the parting line on the top to split core and cavity, minimize undercuts, keep it smooth, filleted, and discreet to prevent flash and ease ejection.

  • Design Guidelines9:42

    Follow a structured design flow for manufacturable plastic parts, from defining requirements to material selection and packaging data. Plan fixations, tooling direction, rib geometry, and draft angles for reliable molding.

Requirements

  • Basic knowledge of CAD software (CATIA V5 preferred, but not mandatory). Interest in automotive product design or plastic component design. Access to a computer/laptop with CATIA V5 (or similar CAD tool) installed for practice. No prior experience in plastic trims required – concepts will be explained from basics.

Description

Are you ready to become an industry-ready CATIA V5 Design Engineer?
This course is designed to transform you from a beginner into a confident professional capable of handling real-world plastic and automotive component design projects. Whether you’re a student, fresher, or working engineer looking to upgrade your skills, this structured program will help you master CATIA V5 step by step.

We’ll start with the basics of plastics, understanding materials, manufacturing constraints, and design properties essential for modern product development. Then, we’ll move into the CATIA V5 Sketcher, covering almost every command used in industrial applications with practical examples and exercises.

Next, you’ll explore Part Modeling, where you’ll learn how to create parametric components with proper design intent, ensuring every part is efficient, editable, and production-ready. The course then advances into Surface Modeling, where you’ll gain hands-on experience with essential tools like Sweep, Multi-Section, and Power Copy — critical for complex automotive design.

Finally, you’ll apply everything in real-world projects, including designing a Cap, Fog Lamp, and Armrest — just like professionals do in the industry.

By the end of this course, you’ll have a strong portfolio, industrial-level confidence, and the skills to excel as a CATIA V5 Design Engineer -- see you in the main course
