Powerful. Limitless. Reliable.
KBS – Kautex Blowsystem
The KBS Series is the most versatile and scalable Platform in the Kautex Portfolio.
Designed for a wide range of applications across automotive, industrial packaging, and specialty products, it adapts seamlessly to diverse production requirements. From plastic fuel tanks, liners, and drums to flat products and even kayaks up to 3.5 m in length, the KBS offers almost limitless possibilities.
Its modular design allows manufacturers to configure the machine precisely to their needs: continuous or accumulator head technology, mono to 7-layer CoEx, single or double station setups, shuttle machines or robot machines. Beyond that, the system supports complex part handling and even the integration of components into the parison before blowing is done— unlocking new levels of efficiency and product innovation.
With the KBS, you don’t adapt your products to the machine — the machine adapts to your products.
Why KBS?
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.

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.
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.
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.
