KBS Series

Kautex Blowsystem

The KBS Series is the most versatile and scalable Platform in the Kautex Portfolio.

Powerful. Limitless. Reliable.

KBS Series – Maximum Flexibility for Diverse Applications

Designed to adapt to demanding automotive, industrial packaging, and specialty applications, the KBS Series combines modular machine architecture with extensive configuration options. From fuel tanks and drums to flat products and kayaks up to 3.5 m long, it allows manufacturers to build a production system around their products rather than adapting products to the machine.

Why KBS Series ?

Powerful

From 400 kN up to 2.720 kN clamping force, the KBS series handles even the toughest jobs - capable of producing articles up to 4 meters long. With die heads reaching 860 mm diameter, throughput of 1.300 kg/h, or accumulator volumes up to 150 liters, KBS delivers the muscle and precision you need to get things done—without compromise.

Limitless

Choose up to 7-layer extrusion systems, configure single or double stations, and integrate robot handling or linear axis automation. With KBS, your options are virtually endless - giving you the freedom to design the exact solution your production demands.

Reliable

With more than 800 systems in operation worldwide, KBS machines have proven their durability and stability for decades. When uptime, consistency, and long-term value matter most, KBS is the partner you can count on.

Process Know How

At Kautex, “Process Know-How” stands for our deep understanding of the extrusion blow molding process – from molten polymer to finished product. We highlight key aspects of machine operation and unique features such as our advanced clamping technology and more.

Clamping Unit KBS

Efficient 3-Platen System – The modular clamping unit offers scalable mold platens and clamping force, giving you the flexibility to adapt to a wide range of applications—efficient, reliable, and future-proof.
Tie-bar free Design – Enjoy unrestricted access for easy part removal and fast mold changes. The open structure ensures shorter setup times and maximum operator convenience.
Dual-Side Distribution – Integrated distributors for mold functions and cooling on both sides enable balanced and efficient cooling, simplified connections, and consistent product quality.
Ground Clearance for Tooling – Enough floor space allows the integration of devices and tools such as spreading units, blow pins, or parison-closing systems—making your production line more versatile and ready for complex geometries.

Die Heads

Continuous Co-Extrusion – Handle even the most demanding applications with up to 7-layer co-extrusion heads, delivering throughputs of up to 1,300 kg/h and die diameters of 600 mm. The result: high-volume capacity with premium parison quality.
Accumulator Heads – Benefit from buffer volumes of up to 150 liters with our FIFO (First-In-First-Out) concept. This guarantees efficient material flow, consistent melt quality, and reliable performance for large-part production.
PWDS & SFDR Integration – Optimize your material usage with advanced wall-thickness control. PWDS and SFDR technologies ensure homogeneous article walls, reduced material waste, and consistently high product quality.

Machine Layout

Flexible Machine Arrangements – No two productions are the same. That’s why KBS machines can be configured to fit your exact requirements and layout constraints.
Tailored Handling Options – Choose between robotic handling or linear axis solutions—whichever best suits your workflow for maximum efficiency and reliability.
Adaptable Orientation & Shuttling – From clamp orientation to shuttling concept, every detail can be tailored to your process. The result: a layout that delivers optimal space utilization, smooth operation, and future-ready flexibility.
