LET'S START WITH THE APPLICATION
Polyurethane is a family of materials with very different properties. We therefore start selecting equipment with the product, its geometry, requirements and planned production volume.
Flexible foams for seats and backs, integral foams with a compact outer skin and rigid systems for moulded furniture parts. The material composition and the mould determine the feel, density, surface and the method of further processing.
Where systems allow it, metal or other inserts are placed in the mould before pouring. The suitable dosing unit then measures and mixes the components.

In sandwich panels, the insulation core bonds the outer facings. SAIP offers CONTITECH continuous lines for production in a continuous flow and DITECH discontinuous systems for cyclic production.
The type of facing, insulation system, panel dimensions and desired output determine the line design. CEDEPA enables development trials, while ENLIVE connects production data.
Continuous or discontinuous route? ↓
The programme includes solutions for seals, filters and dampers, as well as separate dosing systems for elastomers. For these products, the quantity of each dose, repeatability, cycle time and material properties are important.
Another area is the insulation of cooling units, tanks and pipes. For this, the equipment is adapted to the geometry of the product and the filling method.

Water transfer decoration makes it possible to apply a pattern to suitably prepared three-dimensional objects. It is used on plastic, metal, wood and other suitable substrates.
This is a surface finishing process that can complement a product made of PU or another material. It does not replace the choice of base material and its design.

The product shape is not yet the complete technological process. The formulation, dosing, mixing, mould and process conditions are also important.

Discover Butterfly ↓01 / CHEMISTRY AND FORMULATIONS
Official page ↗Pozzi-Arosio is a development and production specialist for formulated polyurethane systems — known in the industry as a “system house”.
Its task is to build the material for a specific application. Flexibility, density, surface appearance and processability differ between PU families, so formulations are selected together with the product requirements and processing technology.
The programme covers flexible, integral, compact and foamed rigid systems, as well as low-density foams for insulation. Applications range from furniture and moulded items to technical parts and thermal insulation.
Explore Pozzi-Arosio
Cold-moulded foams for seats, backs, cushions and armrests. Complex geometry is formed in the mould.
A foamed part with a dense outer surface that can accurately replicate the texture of the mould and include embedded inserts.
Systems for moulded items, prototypes and furniture parts. For AROFLOW AF 514 GREEN PLUS, Pozzi-Arosio describes the possibility of colouring or DipPrint finishing.
The ranges are the manufacturer's data for the systems or families listed. They are not universal properties of polyurethane or the technical specification of your product.
02 / DOSING, MIXING AND LINES
Official page ↗SAIP develops equipment from standalone dosing units to complete polyurethane processing lines.
The choice is not determined only by kilograms per minute. The dose size, component properties, number of ingredients, mixing method, mould, desired cycle and control requirements are important. High-pressure mixing and low-pressure mixing with a mechanical mixer are different technologies; suitability depends on the specific process.
HIGH PRESSURE
High-pressure family for dosing and mixing polyurethane systems.
The manufacturer states PLC control with a touchscreen or industrial PC. The method of flow adjustment, additional components and options are determined by the unit version.
LOW PRESSURE
Dosing and mixing of foamed and non-foamed PU systems.
PLC and touchscreen allow parameter setting and display. The manufacturer states component flow control with frequency converters. Conditioning and cleaning equipment is selected according to the version.
SMALL DOSES
Special applications where small quantity and dosing accuracy are important.
SD is intended for special processes with micro quantities of PU. The required dosing size, repeatability and cycle must be defined on the basis of your product and material.
Selected machine families are shown. The flow range does not mean that every individual version reaches it. We confirm the configuration and performance for your material and application.
SAIP EL is intended for metering and mixing elastomers based on MDI prepolymers. This programme is separate from the general selection of foaming equipment.
INSULATED PANELS
Panel production in a continuous flow: facing preparation, dosing, core forming in a continuous press, then cutting and further handling of the panels.
The programme includes configurations for PUR/PIR and also for mineral wool. Mineral wool requires suitably adapted line sections; it is not the same material or the same foaming process.
Panel production in individual cycles. The solution is attractive for smaller series or a varied programme where flexibility is important.
The press, dosing unit and product handling are adapted to the dimensions, facings, insulation system and production requirements.
03 / AUTOMATION AND SOFTWARE
Official page ↗ENLIVE connects industrial automation and digital production monitoring. Its programme includes PLC control systems, HMI/SCADA user interfaces and machine vision.
Butterfly is a modular platform for process digitalisation. Together with SAIP it has been developed and tested also on continuous sandwich panel lines. The aim is to connect data from the actual process with the information needed by the operator, technologist and maintenance team.
Capturing process parameters and reviewing them together helps identify deviations and find the source of the problem.
Illustration of data linking. This is not a screenshot of the Butterfly user interface.
The selection of modules, sensors, data connections and integrations is defined for the specific line. The software supports the team’s work; it does not replace process preparation, training or maintenance.
04 / DEVELOPMENT AND TESTING
Official page ↗
CEDEPA combines an industrial test line and a laboratory for the development of insulated panels.
The centre in Tudela, Spain, enables testing of materials, facings and process solutions on an industrial scale. Development series can be carried out without interfering with the customer’s regular production.
The programme includes product development, laboratory testing, preparation for certification and line training. The project objectives, materials, scope of testing and success criteria are defined in advance.
05 / RAW MATERIALS AND SYSTEMS
Official page ↗Intertrading covers the supply of chemical raw materials, PU systems and technical advice in material selection.
The raw materials programme includes polyols, isocyanates, prepolymers, silicone additives and catalysts. The systems offer includes, among others, rigid, integral, flexible and viscoelastic foams as well as binders for agglomerates.
This is the field of chemistry and material supply. When planning a project, the selected system must be matched with the dosing equipment, product properties and production process. Current technical and safety data sheets are obtained for the specific material.
Raw materials programme Systems programmeMaterial properties determine the product requirements and the selected process.
06 / DECORATION OF THREE-DIMENSIONAL SURFACES
Official page ↗DipPrint is a decoration field within Pozzi-Arosio. Using water-transfer of the pattern, it enables finishing of three-dimensional surfaces.
The pattern is transferred from a special film onto the prepared item. Applications include suitable plastic, metal and wood substrates, as well as other materials for which the process is approved.
The solution combines decoration, process and dedicated equipment. For the product, substrate preparation, adhesion, geometry and the requirements for the final surface are checked. The manufacturer's video below shows the actual process.

ADDITIONAL TECHNOLOGICAL OPTION
With the REPUR family, SAIP is developing mechanical recycling and reuse of suitable polyurethane residues, for example from cutting and milling panels. The REPUR LT extension also addresses low-density products.
The possibility of reuse depends on the type and cleanliness of the residue and on the requirements of the new product. The share of recyclate and the achievable properties are verified by tests.
