Plastic Shredder Full Assembly – Part 6 | Fixed Blade Design in SolidWorks

🏗️ Plastic Shredder Full Assembly – Part 6 | Fixed Blade Design in SolidWorks 🏗️

Hi, Hola, Bonjour, Privet, Salaam!
Welcome back to Blueprint Bazaar, your go-to platform for clean, professional CAD, FEA, and mechanical design tutorials. In Part 6 of our Plastic Shredder Full Assembly series, we take a closer look at a component that is crucial to the functionality of the machine — the Fixed Blade.

The fixed blade serves as a stationary cutting edge that works in coordination with rotating blades to deliver the shearing action required for effective shredding. In this SolidWorks tutorial, you’ll learn how to model a precise, durable, and manufacturable fixed blade using standard part modeling tools and best practices for mechanical component design.

We’ll walk you through the entire process — from creating the base sketch and applying critical design features like fillets, chamfers, and mounting holes, to considering stress distribution and wear resistance. This component may seem simple at first glance, but its role in material reduction and shredding efficiency is absolutely vital. We also discuss how to optimize it for production using CNC or laser cutting.

🔧 What You’ll Learn

How to model a fixed blade suitable for plastic shredders using SolidWorks
Techniques for creating clean geometry with sharp and reinforced edges
Applying features like fillet, chamfer, and slot for practical assembly
