Automotive Plastic Design Parameters
Plastic Design Parameters are the engineering rules that decide whether an automotive plastic part will mold successfully, meet OEM quality, and control tooling cost.
Plastic design is not just CAD modeling.
It is about balancing Quality, Cost, and Manufacturability—before the tool is ever made.
🔍 Key Plastic Design Parameters include:
• Material Selection
• Nominal Wall Thickness
• Draft Angle
• Rib & Boss Design
• Fillets & Radii
• Tooling Direction & A-Class surface
Each of these directly impacts part quality, defects, and production feasibility.
🔹 Parameter 1: MATERIAL SELECTION
Material selection is the first and most critical decision in plastic part design.
Before geometry, ribs, or styling—
the material must be locked based on:
• Strength & impact performance
• Heat, UV & chemical resistance
• Mold flow & shrinkage behavior
Right material = stable, durable, production-ready part.
Wrong material = defects, rework, and failures.
