K3D – Kautex 3 Dimensional

Shaping complex Pipe Systems with Precision and Efficiency.

The K3D series is the ultimate solution for producing complex, three-dimensional pipe systems with unmatched efficiency and precision. Specifically designed for applications in the automotive industry, it combines superior functionality, compact machine size, and seamless part quality – with no welding seams and minimal material waste.

Applications such as air ducts, intake manifolds, and fuel filler pipes demand complex geometries that push conventional blow molding to its limits. Kautex’s K3D machines meet this challenge by using suction blow molding or horizontal parison insertion to form parts without pinch seams or excessive flash. The result is cost-efficient, material-saving production with consistently high quality.

For even greater flexibility, the optional SeCo technology (hard-soft-hard) enables precise control of properties such as flexibility and rigidity – making it ideal for duct sections under pressure or requiring enhanced assembly flexibility.

Why K3D?

Seamless

3D blow molding delivers superior part quality by eliminating welding seams entirely. This ensures uniform wall thickness, avoids weak points caused by material accumulation or notches, and maintains full mechanical strength. Even challenging materials - such as those with poor bonding properties or short glass fiber reinforcements - can be processed with confidence. The result: seamless, more durable products with fewer limitations.

Efficient

Lower flash weight makes 3D blow molding inherently more efficient. By reducing material waste, the process allows for smaller extruders, lower clamping forces, simpler deflashing systems, and more compact auxiliaries like conveyors, and chillers. This not only reduces capital investment but also cuts operating costs, as less material processing means lower power consumption in both drive motors and heating systems. Less waste, lower costs, greater sustainability.

Automated

The integration of smart 3D technology and automation ensures high process stability with minimal operator intervention. Precise material handling, automated part removal, and intelligent process control deliver consistent output and higher uptime. For manufacturers, this means greater productivity, fewer errors, and the flexibility to handle a wider range of applications with ease.

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 K3D

Flexibility by Design – Choose between a vertical or horizontal parting line to match your application. Horizontal molds reduce cost and complexity, while vertical molds enable suction blow molding for advanced production flexibility.

Suction Blow Molding Technology – Perfect for pipe- and channel-shaped articles, suction blow molding offers a smarter way to produce complex geometries. The process delivers seamless, more durable parts with significantly less scrap -a win for both quality and sustainability.  

Die Heads

Sequential Coextrusion (SeCo) – SeCo blow molding combines different material layers (e.g., Soft–Hard–Soft) in one part, delivering strength, flexibility, or heat resistance where needed. Perfect for complex ducts and pipes, it ensures lighter, more cost-efficient, and recyclable production with reduced material use and energy demand.

CoExtrusion – Filler pieps require a multilayer parison is no problem for K3D. Up to 7-layer CoEx is possible. 

High Temperature Ready – HT-ready machines process special materials for demanding applications like turbocharger pipes and engine-near components. With tailored options for PA or PPS, they ensure parts that withstand heat and perform reliably even under the toughest conditions.

PWDS Integration – Optimize your material usage with advanced wall-thickness control. PWDS technology ensure  homogeneous article walls even at heavily bended pipes and consistently high product quality.

Parison & Article Handling

Industrial Robots – Manage both parison and article handling, giving you maximum flexibility in product design and process flow. This ensures precise, reliable operations while opening the door to more complex geometries and integrated production steps.

K3D Options

Engineered around You - Customizable and tailored to Your specific Needs.

Starting from a standard model, we offer a wide range of upgrade options to create a tailor-made solution for every application.

Layout

K3D Machines gives you freedom in designing your production line. Choose between single- or double-station machines with either a compact mono-layer platform or a flexible CoExtruision design tailored to your products. Handling can be configured for maximum efficiency with robotic transfer or linear systems for parison handling and article take-out.

Suction Blow Molding Technology

Perfect for pipe- and channel-shaped articles, suction blow molding offers a smarter way to produce complex geometries. The process delivers seamless, more durable parts with significantly less scrap -a win for both quality and sustainability.  

Flexibility by Design

Choose between a vertical or horizontal mold parting line, depending on your application. A horizontal setup allows easy parison insertion and reduces mold costs thanks to lower complexity and clamping force. The vertical arrangement supports suction blow molding, offering flexibility for specialized production requirements.

High Temperature Ready

HT-ready machines handle special materials for demanding high temperature applications like turbocharger pipes and engine-proximate components. Special options for PA or PPS-based materials ensure reliable production of parts that withstand heat and maintain performance—engineered for durability and confidence in the toughest conditions.
