Selected components and parts
Die Heads
Alloy steel die heads with heater bands and adjusting screws for profile optimisation, for LabEx laboratory extruders and Multi-X extruders. New to blown film? Read our beginner’s guide to blown film extrusion.
For blown film

Blown Film Die Heads
Alloy steel die heads for blown film, from single-material structures up to advanced five-layer barrier structures. Each layer count will get its own page shortly.
For pipes, tubes, profiles and filaments

Pipes & Tubes
Die heads for small-diameter pipe and tube trials on laboratory and compact extruders.

Profiles
Profile die heads for developing and testing custom cross-sections.

Filaments & 3D Print
Die heads for filament production, including materials used for 3D printing.
Extruder Screws and Barrels
Wear parts and upgrades for the extrusion unit itself. Not sure which material needs which screw design? See our guide to polymers and biopolymers.

Extruder Screws
From Ø18 to Ø30 mm, barrier and general-purpose designs, chrome-plated for a long service life.

Barrels
Smooth barrels for standard feeding, and grooved barrels for improved throughput. Both nitrided for wear resistance.
Extruder Accessories
Filtration and material feeding equipment for the extrusion unit.
Screen changers, Ø20–60 mm extruders

Manual Screen Changers
Manual screen changers for extruders from Ø20 to Ø60 mm, for quick filter replacement without stopping production for long.
Material feeding

Rip and Tip Station
Station for opening and emptying material bags directly into the feeding line.

Venturi Loaders
Compressed-air Venturi loaders for transporting material to the hopper without a separate vacuum pump.

Vacuum Loaders
Vacuum loaders for automatic, dust-free transport of granulate to the extruder hopper.

Material Hoppers
Stainless steel hoppers in various capacities for feeding, closing and material removal.

Press Feeder
Press feeder for flakes and granulated rigid materials, feeding compacted or irregular regrind into the extruder.
Film Line Components
The parts that guide, cool and shape the film between the die head and the winder.

Air Rings
Single-lip air ring with adjustable air flow, for dies up to Ø70 mm.

Calibrating Baskets
Stainless steel roller basket with one-point adjustment, for dies up to Ø70 mm.

A-Frames
Guide frame with stainless steel rollers on high-speed bearings, for stable film transport.

Take-off Units
Nip roller assembly with pneumatic open and close, for controlled film take-off.
Film Inspection Systems
Tools for checking film quality during and after production. Already seeing defects in your film? Our troubleshooting guide covers the most common causes.

Film Inspection Tools
A film inspection light panel for checking film quality and a stroboscope for inspecting fast-moving film without motion blur.
Winders
Winding solutions for different film types, roll formats and production requirements.

Winders
Single-shaft, contact and stack winders are available for different film types and winding requirements. Winders can also be built in accordance with the product and the customer’s requirements.
