We don’t just manufacture components—we solve problems. Our expert engineering team, paired with our full CAD design service, develops specialised foam solutions that meet exact performance, durability, and environmental requirements.

Uncompromising on quality
Certified to ISO 9001:2015 – because quality can’t be optional
At Kewell Converters, quality is built into every layer of our process. We operate to ISO 9001:2015 standards, ensuring consistently high-quality foam parts and bespoke foam solutions that meet even the strictest tolerances.
This matters most in high-risk sectors like defence and aerospace, where performance must be proven and reliability is non-negotiable. With a team of 30 skilled professionals and an advanced production facility, we guarantee attention to detail, accountability, and dependable delivery across every project.
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.
Quick turnaround of samples and advice on feasibility issues, quality of products supplied usually to the standard expected or above, and expectations met in terms of lead times.
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.
