How to Prepare a CAD File for CNC Plastic Machining: STEP, DXF and What Your Machinist Needs
Getting your CAD file right before submission is the fastest way to shorten lead time and avoid rework. This guide covers file formats (STEP vs DXF and when to use each), what your 2D drawing must include, how to specify tolerances for plastic materials, surface finish callouts, material specification, and the seven most common submission mistakes.
What Is Design for Manufacturing (DFM)? A Practical Guide for begineers
DFM isn't a final checklist — it's the discipline of designing parts so they can actually be manufactured. This guide covers the 7 core DFM principles, the specific rules for injection moulding, CNC machining, and plastic fabrication, what a DFM report contains, and what common DFM failures cost to fix.
Plastic Part Design for Injection Moulding: 10 Rules That Prevent Costly Rework
Most injection moulding failures are design failures — geometry created without knowing the rules. These 10 plastic part design guidelines cover wall thickness, draft angles, ribs, bosses, gate location, parting lines, shrinkage, undercuts, snap-fits, and weld lines — everything you need to know before submitting a drawing for tooling.
