Perfect surfaces for the highest demands
Die-cast parts require more than just dimensional accuracy; they need flawless surface quality to meet the highest standards in the automotive, aerospace, furniture, fittings, electrical and other industries. At KULLEN-KOTI, we specialise in providing advanced brush solutions that ensure every component leaves the production line in perfect condition.
Perfect finishing of complex die-cast parts
Our expertise lies in understanding the special challenges of die-cast materials such as aluminium, zinc and magnesium. These components often have complex geometries and thin-walled structures with very high strengths in some cases, making subsequent surface treatment a crucial step in the manufacturing process. Whether it’s removing flash, ejector marks and other burrs produced during the die casting process, cleaning residues or preparing surfaces for coatings, our brushes deliver consistent results with maximum efficiency.
Your advantages with Kullen-Koti at a glance
KULLEN-KOTI has in-depth application expertise in the processing of:
- Aluminium, magnesium and zinc die casting
- Sand, mould and investment casting
- Structural and safety components
Our tools are specially designed for typical casting processes such as deburring, edge rounding, cleaning, smoothing and finishing.
High process reliability in automated lines
Stability is particularly important in series production:
- Consistent machining results
- long service life
- Short tool change times
KULLEN-KOTI tools are robust, durable and designed for continuous industrial operation, ideal for robotics and inline applications.
The right brush for every challenge
We offer a comprehensive range of brushes tailored to different requirements.
- Wire brushes with very soft and fine wires through to extremely aggressive steel wires, as well as grinding brushes with different grain sizes, ensure the desired deburring result.
- Plastic brushes and brushes with animal hair ensure gentle cleaning of parts and are used for sealing moving machine parts.
- Bei Bauteilen, die eine hohe Oberflächengüte benötigen, kommen ebenfalls unsere Schleifbürsten in unterschiedlichen Bauformen zum Einsatz. Und wenn Standardlösungen nicht ausreichen, sind unsere
- Our grinding brushes in various designs are also used for components that require a high surface finish. And when standard solutions are not sufficient, our
special brushes are designed for complex tasks such as cleaning and deburring holes, cross-cuts and automated processes. Every brush we manufacture combines durability with precision and helps manufacturers achieve high-quality results while optimising production efficiency .
Compared to other deburring methods, brush deburring can be integrated into the production line with relatively little effort, without the need for external processing of the components.
