Equipment

Components that define the process.

OEM-independent selection, engineering and integration of key components for demanding extrusion processes – from plasticising to forming.

Process chain

Engineering across the extrusion process.

We do not consider components in isolation, but as part of the complete process. Polymer, formulation, throughput, pressure, temperature, wear and product quality determine the engineering design.

CONTROLMeasurement & control

Screws & barrels

Designed for process, material and service life.

Screws

Geometry and material are jointly matched to polymer, fillers, pressure build-up and wear mechanism.

Single and twin screws, co- and counter-rotating
Diameter 18–800 mm, length up to 12 m
Barrier screws, mixing and shearing sections, special geometries
Nitriding, flight hardfacing and hardfacing welding
New manufacture and reconditioning

Barrels

From nitrided standard barrels to highly wear- and corrosion-resistant bimetallic systems.

Single barrels 18–800 mm, length up to 12 m
Parallel or conical twin barrels, up to 6 m or longer in multi-part design
Bimetallic liners and special materials
Housings and liners for twin-screw extruders
OEM-independent material pairing

Manufacturing & quality: Depending on the application, we work with specialised international manufacturing partners. Engineering, specification, project execution and quality assurance are coordinated for the customer; logistics and import handling can also be managed completely.

Melt pumps

Constant melt flow. Precise pressure build-up.

Gear melt pumps stabilise volumetric flow, relieve the extruder during pressure build-up and create reproducible conditions upstream of the die and downstream components.

* Theoretical output; actual throughput depends on polymer, density, viscosity, temperature and pressure conditions.

Screen changers

Filtration matched to contamination and process continuity.

Sheet

Robust single- and double-plate systems for industrial standard applications and high throughputs.

Piston

Compact single- and twin-piston systems for continuous extrusion processes.

Continuous

Automatic screen transport controlled by time or melt pressure for minimal process interruption.

Manual

Simple and economical systems for smaller throughputs and less critical applications.

Depending on the design, throughputs up to around 6,000 kg/h and standard operating pressures up to 35 MPa are possible; special versions are adapted to the specific process.

Precision Die Technology

The die as a process-defining key component.

Rheology, melt distribution, residence time, temperature control and profile uniformity are matched to the application and existing extrusion line.

Cast & Flat Dies

Mono and coextrusion dies for cast film, sheet and technical and optical applications.

Single-Manifold and Multi-Manifold
Feedblock coextrusion
Flexible lip and profile adjustment
Application-specific flow-channel geometry

Blown Film Dies

Custom die concepts for mono and coextrusion, material changes, retrofit and demanding layer structures.

Homogeneous melt distribution
Controlled residence time
Multilayer systems
Integration into existing lines

Coating Dies

Precision slot dies for liquid and paste media – from functional coatings to battery electrodes.

Anode and cathode coating
Defined coating thicknesses and patterns
Continuous and intermittent processes
Die + dosing as a matched system

Nonwoven Dies

Precision dies for meltblown, spunbond and composite nonwovens.

Working widths 1,600 / 2,400 / 3,200 mm
Optimised melt and air flow
PP, PET and other thermoplastics
High-precision manufacturing and surfaces

Automatic Die Profile Control

IM System: from measurement to closed loop.

Measure the thickness profile, calculate deviation, automatically correct adjustment bolts and measure again. The combination of precision die, mechatronic lip adjustment and inline measurement enables fast automatic profile optimisation.

MEASURE→ANALYZE→ADJUST→VERIFY

Documented PET sheet control trial

13,36 µm initial sigma3,87 µm after 6 minutes−71 % profile deviation

Test conditions and achievable values depend on the application; the case is a documented example of closed-loop control.

Rework & Retrofit

Upgrade instead of replace.

Existing extrusion lines can be selectively upgraded with new key components, revised geometries and modern control technology.

Reconditioning of screws and barrels
Rework and replacement of existing dies
Adaptation of materials and wear protection
Integration of new pumps, filters and dies
Automation and measurement-system retrofit

Complete lines

When required, we also develop and implement complete-line concepts together with selected machine-building partners.
