Aluminium, sheet metal, stainless steel and steel
For the mechanical treatment of metal surfaces, we use the following manufacturing processes, among others:
We have a factory-owned 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 choice of over 210 RAL colours, which we deliver just-in-time. For special requirements, we provide the surfaces for example with 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:
For the required 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).
Housings or front and side panels can be adapted to a new look and feel using versatile anodised coating options and printing processes, so that a new premium segment can be created and a new target group opened up to our customers.
In addition, our innovative smart surfaces create lighting effects behind perforated metal surfaces as desired or equip them with individual sensor control.
In a further stage of the value chain, we provide components with the desired surface colour and structure. In the area of colouring, we use powder coating and anodising processes, and in the area of structuring, we use mechanical treatment, screen and tampon printing, lasering and etching technologies.
After the development phase, we manufacture assemblies from different components and materials in series and prepare them for installation 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.
Final assembly is carried out manually, semi-automatically or fully automatically, depending on the assembly.
“Every year, 20 million assemblies leave our factory in Germany in a three-shift operation.”

FAQs
Please take into account that our production is geared towards medium to large series production. We are therefore unable to process requests for very small quantities for economic reasons.
We ask for your understanding that we cannot consider requests from private individuals of any kind.
