Manufacturing Solutions for Demanding Toll Manufacturing

Technical toll manufacturing requires more than available production capacity. The right process, proven process expertise and production that delivers reproducible results are equally important. Diffutherm combines specialised mixing, kneading, dispersing and reaction technologies with many years of experience in manufacturing technical products.

Production is based on customer-owned formulations. Where required, we also support the adaptation of formulations and the selection of alternative raw materials, for example in response to regulatory changes or increasing sustainability requirements. A range of manufacturing processes and batch sizes enables us to tailor production to the specific product and required production volume.

Manufacturing that fits the product

Viscosity, raw materials, formulation and the required product properties determine the demands placed on the manufacturing process. Our production capabilities are designed to cover a correspondingly broad range of requirements.

Our machinery includes a variety of technologies for manufacturing adhesives, coatings, corrosion protection products, waxes, dispersions, emulsions and other technical formulations.

The production route does not necessarily have to be fully defined from the outset. Customers with an existing formulation and clearly defined process specifications can rely on Diffutherm’s technical infrastructure for implementation.

Manufacturing solutions for different process requirements

The focus is not on the individual machine, but on the role it performs within the production process. Depending on the product, formulation and required volume, we therefore use different mixing, kneading, dispersing and reaction processes.

Mixing and kneading high-viscosity systems

High-viscosity adhesives and comparable formulations place specific demands on the mixing and kneading process. We have a range of equipment available for processing these products, covering different formulations and batch sizes.

Z-Blade-Kneaders

Z-Blade-Kneaders are used to manufacture solvent-free and solvent-based adhesives. They enable the production of semi-finished and finished products in batch sizes ranging from 1,000 to 2,000 litres.

K-Mixers

Vertical K-Mixers are available for complex adhesive formulations. With batch sizes ranging from 1,500 to 6,000 litres, they extend our capabilities for different production volumes and formulation requirements.

Butterfly Mixers

Butterfly Mixers are used, among other applications, for high-viscosity solvent-based adhesives and water-based underbody protection products. The equipment features cooling, vacuum and discharge systems and operates with batch sizes of around 1,200 litres.

Dispersing and mixing coatings, waxes and compounds

Coatings, waxes and complex compounds require controlled incorporation and distribution of their components. For these production tasks, we use different dissolver systems.

Dissolvers

Dissolvers are used, among other applications, for water- and solvent-based underbody protection coatings. The available equipment covers batch sizes ranging from 1,000 to 8,000 litres and is directly connected to the tank farm.

Master Dissolvers

Master dissolvers are available for more complex formulations. They are used, among other applications, for bitumen-based coatings as well as polyol, epoxy and polyester compounds and enable the processing of performance additives and fillers. Batch sizes range from 3,000 to 5,000 litres.

Manufacturing dispersions and emulsions

Where components need to be intensively distributed or dispersed, specialised high-shear processes are used.

High Shear Rotor Stator Mixer

At Diffutherm, the rotor-stator high-shear mixer is used, among other applications, for cavity waxes as well as water- and solvent-based dispersions and emulsions. Heating and cooling systems, vacuum technology and the rotor-stator mixing unit enable controlled processing in batches of approximately 4,000 litres.

Reactive manufacturing processes

For certain products, manufacturing involves more than mixing alone. Where controlled reactions form part of the production process, suitable reactors are available.

Reactors

Diffutherm’s reactors are used to manufacture solvent-based high-performance corrosion protection products as well as waxes. They enable, among other processes, temperature-controlled neutralisation reactions at temperatures of up to 140 °C and cover batch sizes ranging from 4,500 to 7,500 litres.

Your product is the starting point – not the machine type

Companies looking for a toll manufacturer do not necessarily need to know in advance which machine should be used to manufacture their product. The key factors are the formulation, product properties, raw materials, required volume and the demands placed on the manufacturing process.

If a proven formulation with clearly defined process parameters already exists, we can assess which of our available manufacturing technologies can meet those requirements. If the product itself has been defined but its formulation or production process has not yet been finalised, development, laboratory and manufacturing capabilities can be considered together.

This makes our machinery the technical foundation for a robust and reproducible production process.

From formulation to finished product

Diffutherm can take responsibility for more than the manufacturing step itself. Depending on the project, different services can be combined across the production process.

Formulation and development

Production is based on customer-owned formulations. Our in-house laboratory and development team support projects in which formulations need to be adapted, prepared for industrial manufacturing or adjusted to changing requirements.

We also have experience in evaluating and selecting alternative raw materials – for example, when existing raw materials need to be replaced due to regulatory requirements or when more sustainable alternatives are required.

Raw material sourcing

The raw materials required for production can be sourced by Diffutherm and made available for the respective order. This allows raw material procurement and production planning to be coordinated within a single manufacturing process.

Toll manufacturing

Our broad range of machinery covers different viscosities, product types and process requirements. Depending on the project, mixing, kneading, dispersing or reaction processes can be used.

Packaging

On request, Diffutherm can also handle the packaging of the manufactured product. This allows our scope of service to extend beyond production itself through to the finished product.

Different batch sizes for different production requirements

Production orders vary not only in formulation, but also in the required volume. Depending on the process, our different production units accommodate a variety of batch sizes and therefore provide a broad range of production volume options.

The most suitable equipment and production volume for a specific order depend on the product, formulation and process requirements. Our broad machinery base provides the flexibility required to accommodate these differences.

Process expertise for reproducible quality

Technical equipment alone does not make a reliable toll manufacturer. What matters is the ability to transfer formulations and processes safely into production and to maintain the required product quality consistently across recurring production runs.

Diffutherm combines many years of manufacturing experience with technical expertise, an in-house laboratory and its own development capabilities. Different production processes allow us to respond to the requirements of a wide range of formulations and product groups.

Confidentiality is also a central consideration for customers with proprietary formulations. Product information, formulations and process know-how are treated as sensitive elements of the collaboration.

The result is a manufacturing solution that brings together production capacity, technical understanding and reliable quality.
