Die head technology is the heart of every extrusion blow molding machine – it defines wall thickness accuracy, material efficiency, and overall product quality. At Kautex, we design and manufacture high-performance die heads tailored to your materials, your application, and your production goals.
Die Heads #madebykautex
Whether you’re working with accumulator heads for large, thick-walled parts or continuous heads for fast and multi-layer production, we offer the right solution. Our servo-driven tooling, optimized flow channel designs, and decades of experience in co-extrusion ensure stable processes, short cycle times, and flexible product changeovers.
All Kautex heads are modular, easy to maintain, and compatible with a wide range of plastics and recyclates – creating the foundation for efficient, reliable, and future-ready plastic processing.
Die Heads Variations
Accumulator Die Heads
Discontinuous Extrusion for Large-Scale Performance
Powerful. Precise. Proven.
Accumulator heads from Kautex are ideal for producing large, thick-walled, or technically demanding hollow parts – such as fuel tanks, IBC containers, surfboards, spoilers, or kayak shells. When long parison lengths or tough materials are involved, discontinuous extrusion is the superior process.
In this method, the melt is not extruded continuously but stored in a FIFO accumulator and then discharged in a single pulse. This results in minimal sagging, excellent wall thickness control, and consistent melt homogeneity – all critical for maximizing your productivity and product quality.
Your advantages with Kautex accumulator heads:
- Unmatched process stability for large blow-molded parts
- Handles low-viscosity and stiff-melt materials with ease
- Low-maintenance, long-life construction – built for industrial performance
- Homogeneous melt flow through optimized storage and flow channel design
- Perfectly suited for HDPE, PA, LDPE, recyclates & technical polymers
As a Kautex customer, you get more than just machinery – you gain a partner. Our specialists support you in material selection, head design, and process simulation. With our deep rheological expertise and cutting-edge manufacturing, we help you achieve reliable, efficient, and sustainable production – tailored to your needs.
Continuous Die Heads
High-Efficiency Multilayer Packaging
Faster. Multi-Layered. High-Performance.
Continuous extrusion is the go-to method for producing plastic containers up to 1,000 liters—especially for multilayer applications in consumer, industrial, pharmaceutical, or medical sectors.
In this process, polymers like PE, HDPE, PP and PA are extruded continuously to form a parison that remains unbroken—ideal for high-volume, seamless production
Why Kautex leads in continuous extrusion:
- Up to seven layers in one parison—enabling advanced barrier structures and material blends
- Optimized geometry for fast color changes.
- Superior energy efficiency thanks to optimized flow paths and die design
- Recyclate-ready configurations, tailored for sustainable material usage
This nonstop process guarantees consistent wall thickness—crucial for shelf-stable, barrier-enhanced packaging.
Your advantages with Kautex continuous heads:
- Reliable, high-throughput production
- Four- to seven-layer capability for advanced barrier performance (e.g., PA, EVOH)
- Flexible integration of recyclates alongside virgin materials
- Quick-change systems and smart split tools are used for set-up
Powered by our deep rheological expertise and state-of-the-art simulation tools, we deliver head systems that meet current demands—and tomorrow’s standards.
