The service portfolio includes:
After the development phase, we manufacture assemblies from different components and materials in series and prepare them for assembly in our cost-effective plants. In addition to the development of assemblies, Gronbach’s core competencies lie in the connection of the individual components using our comprehensive bonding and joining technologies.
Functional and design-oriented components made of aluminium, sheet metal, stainless steel and steel with various methods of pre- and post-treatment, including products such as
We focus our hinges and pull-out systems on the household appliance industry, for which we have been developing and mass-producing innovative solutions for more than 50 years, including for ovens, freezers, refrigerators and dishwashers.
We adapt our existing kinematic solutions to the individual situation and customer requirements in order to achieve a perfect fit. Through our platform, we are not only able to adapt our solutions to new household appliance models, but also to alternative application areas and industries.
At Gronbach, we develop or optimise complete fan systems or individual fan elements according to customer requirements. We analyse the motorisation, power electronics, ducting and available installation space for the required flow efficiency and minimise any noise emissions at the same time.
We injection-mould the plastic fan wheels ourselves in our plants. They are used in the drive technology, automotive, railway, ventilation, air-conditioning and refrigeration technology industries, as well as in the household appliance industry and in the field of domestic ventilation.
Our fan wheels guarantee perfect concentricity and no imbalance.
We supply a wide range of industries that place the highest demands on the functionality, design and quality of their products.
Our cross-functional group of companies combines three divisions into a full-service supplier for the development and series production of devices, technical assemblies and components made of plastics and metals, as well as for the design and optimisation of ventilation systems.
Sheet metal, steel, stainless steel, aluminium
Gronbach relies on reliable and innovative surface treatments for design applications in the processes of forming and joining non-rusting metals such as stainless steel or aluminium, including by means of:
We have our own anodising plant that can support you with the following finishing processes:
In addition, various forms of pre- and post-treatment are possible, for example brushing, grinding, blasting, polishing, special pickling and lasering.
Using our own powder coating facility, we coat components with a range of over 210 RAL colours, which we deliver just in time. For special requirements, we can treat the surfaces with, for example, anti-stick or anti-fingerprint coatings.
For the visual labelling of functional components and other products, e.g. with logos, symbols or lettering, we use various processes for individual decorative and functional coatings:
To achieve a substructure of metal components and metal foils, we back-inject them with the required plastics.
We design and manufacture the plastic injection moulding tools required for this ourselves in order to avoid distortion due to shrinkage and different linear expansions. Furthermore, we integrate the desired electronics or lighting elements during back-injection moulding.
We join components using a wide variety of methods. In bonding, we use liquid adhesives, adhesive tapes and also adhesive die-cuts, which we apply manually or robotically. Optionally, different types of pre-treatment are possible, including plasma, primer, scarfing or pyrosil as well as different rapid curing methods (UV light, infrared, heat radiation).
