ELASTOMACH series · PU elastomers
ELASTOMACH PU elastomers under total control.
Low-pressure casting machines with flexible configuration and simple operation for pouring the full range of polyurethane elastomers on the market — with the temperature, metering and mixing rigour these materials demand.
- up to
- 150 kg/min output
- up to
- 1,000 litres per tank
- up to
- 150 °C temperature
- up to
- 4 additional components
Why elastomers
Few materials deliver what PU elastomers do.
Every year brings more applications for polyurethane elastomers. Hardness, abrasion resistance and elasticity deliver results few materials can match. The strict control these raw materials require is built into the ELASTOMACH series: productive efficiency and final-product quality.
- Hardness
- Abrasion resistance
- Elasticity
Technology in detail
Every step designed for a defect-free part.
-
Dynamic mixing head
Adjustable speed to suit each type of material. The head’s design geometry ensures perfect mixing.
-
Powerful, programmable heating
Electronic control keeps raw-material lines at stable, programmed temperatures. Programmed pre-heating: the machine is ready at the start of the shift.
-
Process parameters under control
Accurately controls and monitors process parameters while keeping the system stable.
-
Pouring precision
Process controls combined with high-precision gear pumps: constant flow and precise pouring.
-
Continuous recirculation
Stable viscosity and temperature right up to the pour — and less waste at start-up.
How it works
From heated tank to precise pour.
- 01 Heated tanks 2, 3 or 4 tanks up to 1,000 L, agitators in prepolymer tanks, vacuum replenishment.
- 02 Degassing Built-in vacuum pump and automatic degassing for bubble-free parts.
- 03 Recirculation Uniform temperature and viscosity, stable process.
- 04 Metering Precision gear pumps with electronic speed and pressure control.
- 05 Mixing Dynamic head: chamber geometry, rotor, speed and mixing time tuned for each system.
- 06 Pouring Pouring programs, recipes and control of every shot.

Materials and techniques
The elastomers you use, the way you produce.
Processable materials
- Hot-cast elastomers
- Cold-cast elastomers
- MDI and/or TDI systems
- Polyether or polyester
- Cellular systems
- Special formulations
Casting techniques
Bottom filling
Filling from the bottom of the mould to reduce air entrapment.
Continuous casting
Continuous production of profiles or parts.
Individual shots
Independent control of each shot.
Rotational casting
Application onto rotating parts such as cylinders and rollers.
Under vacuum
Removal of bubbles and gases during casting.
Pressurised
Optimised control for specific formulations.
Two ways to start
Standard configuration or custom-engineered.
Standard configuration
Modular build, ready to grow with your production.
- Modular structure
- 2 to 4 components
- Simple expansion
- Shorter lead time
- Easy maintenance
Custom-engineered
Designed from the customer’s specification, from micro-dosing to complete cells.
- Micro-dosing or high outputs
- Mobile systems
- Robotic integration
- Complete production cells
- Number of components to suit the project
Advanced features
Automation, safety and sustainability in one machine.
Features available depending on configuration and project.
Additive injection
Pigments, catalysts, UV stabilisers and modifiers straight into the mix: fast colour change and tuning of reactivity and cure.
Auto-calibration
Automatic correction of deviations, better output accuracy, fewer human errors and shorter set-up.
Exposure reduction
When the oven is opened: automatic gas extraction, internal equalisation and only then door release. Safer for operators.
Continuous degasser
Removes dissolved gases and feeds the machine without interruption: fewer bubbles, more stability.
Amine feeding
Closed loading compartment, automatic feeding and melting unit: less exposure to dust and vapours.
Recycled materials
Processing with recycled PU, TPU and rubber or industrial scrap: circular economy and less waste.
Cartesian robot
Three-axis movement of the mixing head: automated application, repeatability and positioning accuracy.
Mould recognition
The machine identifies the mould and loads the recipe, volume, parameters and matching automation program.
Rotational casting
Coating cylinders and rollers without a conventional mould: less waste, energy savings and thick layers in a single operation.
Vacuum batch mixing
Small quantities with programmable recipes: formulation development, pilot runs and special batches.
Operator interface
Colour touchscreen, fully PLC-controlled.
The HMI brings together recipes, real-time control, alarms and history — and connects to support and to your plant management.
- Intuitive navigation
- Recipe management
- Real-time control
- Production history
- Alarms and diagnostics
