KNARR Standard Mould Bases and Components for Moulds
In 2011, Gunther UK expanded its portfolio by introducing Knarr GmbH – a fast-growing, innovative manufacturer of high-quality standard and custom mould components. Today, Knarr is a trusted name across the UK and Ireland mould-making industries, offering a vast range of industry-standard mould bases, ejector pins, pillars, bushes, sleeves, and more.
Beyond the standard range, Knarr’s advanced manufacturing capabilities allow the production of special components to exact customer drawings and specifications.
Their expertise includes:
- DLC and Cr2N-coated components – ideal for medical and food packaging industries where no lubricants are required.
- Patented stepless ejector sleeves for superior performance.
- Blade ejectors with 2 or 4 corner radii for versatile applications.
- Bespoke collapsible cores – with or without finished contours.
With competitive pricing, short lead times, and no minimum order quantity, Knarr delivers both precision and flexibility.

Major UK OEM
Gunther’s demonstrated technical knowledge allow us to confidently provide working, robust moulds that produce consistent parts. Delivering a quality product and incredible support are more important today than ever before, Gunther never fails to deliver this, which in turn helps us to provide the same service to our customers. I can’t recommend them enough.
UK Toolmaker/moulder
We’ve been working with Gunther UK since 1988, and they’ve never let us down. The combination of personal service, trustworthy advice, and consistently high-quality hot runner systems and mould components has cemented our relationship over three decades. They feel less like a supplier and more like a partner we can rely on.
