Equipment
We focus on the key components of extrusion. For screws and barrels, we work with one dedicated specialised technology partner. JCTIMES is our partner for screen changers, melt pumps, static mixers and extrusion dies. We have worked with JCTIMES for almost ten years. These components have a decisive influence on process stability, output, product quality and scrap.
Process chain
An extrusion line is only as capable as the interaction of its key components. Screw and barrel determine plasticising and melting behaviour. Screen changer and melt pump influence filtration, pressure stability and throughput. The extrusion die ultimately determines uniform melt distribution and forming.
Correct design and coordination of these components are essential for a stable process, high output, consistent product quality and minimum scrap.
Screws & barrels
Geometry and material are matched to polymer, fillers, pressure build-up and wear mechanism.
From nitrided standard barrels to highly wear- and corrosion-resistant bimetallic systems.
JCTIMES Screen Changers
Robust single- and double-plate systems for industrial standard applications and high throughputs.
Compact single- and twin-piston systems for continuous extrusion processes.
Automatic screen transport controlled by time or melt pressure for minimal process interruption.
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.
JCTIMES Melt Pumps
JCTIMES gear melt pumps provide a uniform, reproducible melt flow and relieve the extruder of pressure build-up. They create stable process conditions upstream of the die and downstream components, supporting consistent product quality and high output.
Constant volumetric flow and stable pressure build-up for reproducible process conditions.
Design matched to polymer, throughput, pressure, viscosity and process temperature.
Available with gearbox, coupling, motor and required mechanical components.
Available with control system and support for integration into an existing extrusion line.
JCTIMES Precision Die Technology
Rheology, melt distribution, residence time, temperature control and profile uniformity are matched to the application and existing extrusion line.
Mono- and coextrusion dies for cast film, sheet, and technical and optical applications.
Custom die concepts for mono- and coextrusion, material changes, retrofit and demanding layer structures.
JCTIMES precision slot dies for demanding functional and industrial coating processes.
Precision dies for meltblown, spunbond and composite nonwovens.
JCTIMES Automatic Die Profile Control
Measure the thickness profile, calculate deviations, automatically correct adjustment bolts and measure the result again. The combination of a precision die, mechatronic lip adjustment and inline measurement enables fast automatic profile optimisation.
Test conditions and achievable values depend on the application; this case is a documented example of closed-loop control.
Die Rework & Retrofit
For rework of existing extrusion and coating dies, we work with local partners in Germany and the USA. Worn or damaged dies can be measured, reworked and readjusted to the specific process.
Depending on scope and die condition, lead time is typically no more than about 4–6 weeks. Extrusion Evolution coordinates technical alignment, rework scope and project execution.
