Perfect in Form and Function
Technical blow-molded parts done right.
Technical Parts
Whether air ducts, filler pipes, or complex 3D-shaped conduits – technical blow-molded parts are essential in modern vehicles. They must be lightweight, durable, media-resistant, pressure- and heat-resistant – and yet cost-effective to produce. Kautex delivers the right machines and technologies for this task.
With decades of experience in extrusion blow molding, we design highly specialized systems for powertrain and under-the-hood applications. Our technology includes suction blow molding, sequential coextrusion, and robot assisted prison positioning for sophisticated 3D geometries. The result: seamless components with complex geometry and optimal wall distribution.
From intake manifolds to turbo lines and fuel filler pipes, we offer modular solutions with advanced wall thickness control (RWDS), robotic automation, minimum scrap during production and energy-efficient performance. Whether small batch or high-volume: With Kautex, you’re equipped for any technical challenge.

Technology Focus – Suction Blow Molding.
Suction Blow Molding
Suction blow molding enables the production of complex, three-dimensional components – seamless, material-efficient, and assembly-friendly. The process draws the parison into the mold using vacuum pressure, ensuring precise shaping even for long or highly contoured parts such as air ducts and filler pipes.
Combined with systems like RWDS (Radial Wall Distribution System), wall thickness can be actively adjusted to meet specific mechanical or thermal requirements, reducing weight and improving performance. A high level of automation ensures process reliability and fast cycle times.
Technical Parts Know-How
Our KBS and K3D series machines are optimized for the efficient production of air duct systems with complex geometries. Thanks to RWDS wall thickness control, critical zones can be selectively reinforced while minimizing material use. The suction blow molding process allows for tight radii and high dimensional stability – ideal for engine bay and turbocharger applications. Robotic take-out and post-processing ensure maximum efficiency.
Your Benefit
Advantages of the suction blow molding process:
- Enables complex 3D shapes without weld seams
- Seamless components for high media and pressure resistance
- Reduced material usage thanks to optimized wall thickness
- Easier assembly with integrated functional elements
- Efficient serial production with short cycles and automated take-out
3D Parts Know-How
Kautex’s K3D series machine platforms enable the production of highly functional, three-dimensional conduit systems. Coextrusion heads, customized suction molds, and centralized article take-out reduce the need for post-processing to a minimum. 3D Pars can be manufactured in a single, fully automated step – accurate, efficient, and installation-friendly.
