Quality at Kewell Converters
We have relied on Kewell Converters to accurately translate quite complex drawings for more than a decade. We would recommend them for difficult work.

Flexible with improving designs and working with sometimes inadequate files, quote turnaround time usually same day and good communication.
Engineered for high performance
Foam that performs under pressure
We understand the demands of extreme environments. That’s why our custom foam components are designed to withstand impact, vibration, temperature extremes, and environmental challenges.
Using advanced foam fabrication techniques and the latest CNC machinery, we manufacture complex foam parts to precise tolerances – whether it’s a lightweight foam panel, foam gasket, strip, or protective insert. Our expertise in specialty foams, including Zotefoams and other branded foams, enables us to match the right material to your performance needs.
Sustainable foam manufacturing
Smart solutions. Smaller footprint.
Sustainability matters — and at Kewell Converters, we act on it. Our processes are certified to ISO 14001, reflecting our commitment to sustainable foam conversion and responsible manufacturing.
We continuously optimise our production workflows to minimise waste, maximise material usage, and reduce energy consumption — without compromising quality. Our goal is to provide manufactured foam solutions that support your ESG goals without compromising performance.
