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.
