On screen first. On the line second.
Calculated, not just learned the hard way.
VulcaRAMix builds a digital model of your entire mixing and vulcanization line and calculates how your profile heats up and cures — before the first metre is ever extruded. No more days of trial runs on the real machine.
One codebase for web, iOS, and Android – the same simulation at your desk as on the shop floor.
How it works
From recipe to finished profile – in five steps. Each step builds on the one before; the result is a complete digital twin of your line.
Recipe
Store your rubber compound with every relevant property. VulcaRAMix calibrates the cure kinetics automatically from your real rheometer curves.
Product
Draw or import the cross-section – parametric, freeform, DXF, or photo. Contour recognition does the rest.
Machine & line
Assemble your equipment from modules, just like in the hall. Configure it once, reuse it forever.
Simulation
One click and the physics engine runs – a fast 1D approximation for everyday work, 2D physics automatically where it makes the difference.
Result
Temperature and cure profile over time, depth, and line position – including target cure time and a warning on overtemperature.
Feature overview
Compound management
Store every compound once, cleanly – then reuse it across any number of products.

Learn moreWhy VulcaRAMix
A digital twin of your own line – machine modules are configured like the real line, not approximated as a generic oven model.
Every formula is documented with its source, symbols, and validity limits – approximations are clearly labeled as such.
A fast 1D approximation for everyday use, direction-resolved 2D physics once belt support, rotation, or nozzle geometry make the difference.
Nozzle and flow corrections come from our own measurement project, not literature values alone.
The technological foundation of the Rameckers Group's shared digital platform – not just a standalone simulation tool.
Scientific basis
VulcaRAMix is not a black box: its calculation foundations come from peer-reviewed research and our own measurement campaigns, not just literature values. The scientific background at a glance:
- Cure kinetics
- HeatStraD-verified cure model, developed through the research partnership with RWTH Aachen's IKV – calibratable from your own rheometer data.
- GEO
- Research project on flow data and heat transfer in hot-air vulcanization, together with the University of Paderborn's KTP – the basis for the holistic energy concept for air guidance and heat transfer (GAK trade publication, 2016).

- IKV HeatStraD
- A publicly funded ZIM project (2015–2017) by Gerlach and RWTH Aachen's IKV – the jointly developed "HeatStraD" measurement device made the temperature profile inside a profile cross-section visible for the first time during hot-air, infrared, and microwave vulcanization.

- From practice
- Science only makes sense when it's validated in practice. That's why the models also account for everyday factors like product position, belt contact, or shadowing – not just lab conditions.
Build your own machines – and simulate competitor machines
On the Enterprise plan you can fully construct your own machines, including modeling competitor equipment – with fine control over real machine parameters such as flow velocity, IR emitter position, and choice of microwave system.
