Main business focus of 2R-Tec GmbH & Co. KG is the batch and high volume production of component parts of fiber-reinforced composites on the basis of recyclable thermoplastics and highly reactive thermosetting plastics.

A large in-house production depth reaching from layout of part, design of forming tool, tool construction, batch production of the fiber-reinforced composite parts up to surface refinement makes it possible to react in a flexible and contemporary way in almost each and every process step.

An up-to-date plant for processing of fiber-reinforced composites – together with our rapid forming procedure – facilitates an efficient batch production of large volumes and gurantees

highest quality resulting in a great advantage for our customers to develop new markets with these light, reinforced composites.

It is our target to develop, by constant improvement, more efficient manufacturing procedures with reproducible processes for batch production of component parts of fiber reinforced composites with thermoplastics and highly reactive thermosetting plastics as matrix.

In this connection we can lean on many years of experience in the field of fiber treatment, plastics technique, mould and fixture design and construction.

2R-Tec is resident in Germany, approx. 100 kilometers north of Frankfurt/Main, in Dautphetal (Hessen). This idyllic region is a stronghold of mould and tool design and construction as well as plastics processing for the automotive industry.

We invite you now to get a comprehensive idea of our company and the great variety of possibilities we can offer on our new website.

SERIES PRODUCTION

Mass-produced reproducible quality

Optimum and controlled manufacturing conditions belong to the production of high-quality composites.

Beside the controlled machine and tool data such as cavity pressure measurings etc. parameters as dust content, humidity and temperature are only some of the process monitored sizes which are required as frame conditions for reversible manufacturing conditions in batch and large volume production.

 In optimum conditions we produce composites on continuous, linear production lines with specially developed processes guaranteeing batch sizes of more than 100.000 pcs/year. according to component part.

 Medium batches   >     10.000 pcs./y
High volumes       >   100.000 pcs./y

DEVELOPMENT

Higher • quicker • further - we are constantly developing

More and more new tasks and demands on material of the component parts and the production processes require permanent development work.
                      Whether chemical or mechanical tests, we try to reach the optimum in quality and process flow with respect to the necessary sizes.

DESIGN

CAD/CAM design with control

With most up-to-date CAD systems we design component parts, forming tools and devices required for batch production.  Conversion of CAD data into machine data (CAM) with control and comparison of the component part tolerances guarantees slightest deviations of your specified values.

3D DIGITALIZATION

3D scanning – quick making out of data

3D scanning facilitates quick and flexible digitalization of dimensions of models, tools, prototypes and many other objects formed as you like, independent of type of material in real time.

As contactless procedure the 3D scanning provides the exact data of the component part geometry.

Size of the part to be scanned can be from 1 mm up to 10 m. For comparison of tolerances, volume models can be compared with these data with CAD design data or even new forming tools and models can be made out.

MODEL DESIGN AND CONSTRUCTION

A model always pays off

Essential parts from planning up to batch production are models and prototypes
which already pay off during the first meeting.

In particular in case of developments where weight and stiffness are important there can often be observed an excess in material. If this is eliminated the STW value (stiffness-to-weight) can still be improved.

Fixtures required for batch production (e.g. for treatment, storage, paintwork and transportation) belong to the scope of the model and fixture design and construction.

MECHANICAL TREATMENT

Component part treatment – precision makes the difference

Treatment of fiber-reinforced composites requires use of different treatments according to type of fiber and demands a lot of the cutting tool, the clamping fixture and the machine.
Special zero-point clamping systems guarantee reversible, precise treatment and quick change of clamping tools.

SURFACE REFINEMENT

The finish matters

Different coating processes and paint systems are used based on surface requirements and batch size.

For larger volumes the reversible process of dip-coating with UV paints which have an outstanding scratching resistance is an ideal coating solution with extremely short cycle times.

In case of small and initial batches as well as prototypes or big component parts up to a lot size of 300 pcs., application of paint by hand in a spray process should be favoured.

Rapid Forming

High speed – in manufacture of composites

The rapid forming process is a process optimized regarding flow and cycle
time for the production of fiber-reinforced parts of medium and large batch sizes.
In optimum conditions of process, component and forming tool up to several thousand
composite parts can be produced a day.
In case of large volumes use of variotherm forming tools made of steel with automatic
ejector equipment etc. is required.
These variotherm tools are normally heated via induction and cooled back to the
demoulding temperature with a liquid or gas cyclically to forming process.
The extremely fast hot/cold cycle is the advantage of these very special tools.

An optimized and automatic production line from precise CNC pre-cut of the
technical fabric, transportation of the fabric and the actual fully automatically controlled
forming process is guarantor for reproducible production processes and high
quality components made of fiber-reinforced composites.

Environment

Ecological and economic advantages

Important aspects for the future are the ecological and economic points of view
and the protection of raw material and resources which become more and more
important even because of legislative initiatives (reduction of CO2 emission).

For the process chain from the raw material carbon which is available nearly
indefinitely to the finished carbon component only approx. 25 % of power
is required compared to the similar part made of steel.

In addition comprehensive and environment damaging antioxidation processes,
e.g. galvanizing in electrolytic bath, are not needed.

Also the decreasing energy required for motion of lightway construction parts,
used for example in vehicles, has a positive result on the total energy balance thus
resulting in a significant reduction of the operating costs.
A current example is the new Boeing „Dreamliner“ 50 % of which consist of carbon
and needs17 to 20 % less fuel due to the weight saving.

Maintenance costs will also be reduced by approx. 15 % by use of composite materials.
