It's episode 300! Host Adrian and Sofeast head of NPD Paul Adams dig into IK ratings, what they measure (impact energy in joules), why they matter for real-world product abuse (drops, kicks, tool strikes), and how to connect use-case, environment, materials, and system-level design choices (wall thickness, ribs, radii, gate location) to hit targets like IK06–IK10.
You’ll hear practical examples (from light switches to job-site drills), polymer options (PP, HIPS, ABS, PC/ABS blends), and environment trade-offs (temperature, UV, chemicals, cost) so your spec says more than “make it rugged.”
Episode Sections:
- 00:12 – Introduction: designing for toughness via IK rating
- 01:58 – IK vs IP: ingress ≠ impact toughness
- 05:16 – What is IK? Impact energy (J); Izod/Charpy context
- 08:33 – IK scale overview: IK00 → IK10 (~20 J)
- 09:18 – Start with real-world use before materials
- 10:15 – Low-impact examples (e.g., light switches)
- 11:56 – Mid-impact examples (bench drops, tools falling)
- 12:50 – High-impact / IK10: sledgehammer territory
- 14:02 – Specify toughness explicitly: choose an IK level
- 17:02 – Mapping joules to IK (≈0.35 J to 20 J)
- 19:34 – Materials at IK06 (~1 J): PP, HIPS, ABS, PA
- 21:47 – Materials at IK09 (~10 J): high-impact ABS, PC/ABS, modified PA
- 25:51 – Designing for IK: thickness, ribs, radii
- 27:18 – Molding realities: gate location, weld lines
- 29:26 – Environment trade-offs: temperature, UV, chemicals, cost
- 33:14 – Same IK, different designs: oil vs building site
- 35:16 – Key takeaway: IK is a system rating
- 35:40 – Wrapping up
