Coating Technology

From the first consultation and new development through the initial sample to series production, we are there for you and offer you seamlessly interlocking services. In this way, we develop the ideal surface technology as well as the corresponding production process for all sectors: according to your individual needs.

A test is the best way to show which coating is suitable for your product. That is why we test and evaluate different surface technologies for your application. In our own laboratories, we produce functional samples for you, for which we have access to a wide range of coating technologies, so that we can select the ideal technology for your product. Our portfolio ranges from PVD, CVD vacuum coating processes to all conceivable types of electroplating, dipping and painting processes to the various applications of thermal spraying.

At Bosch, we're not just coating experts, we're manufacturing specialists. Because of our broad expert knowledge, we manage to efficiently integrate new coating processes into the production chain. We work with proven product development methods such as requirements analysis, failure mode and effects analysis (FMEA), statistical design of experiments (DOE), design to cost, design thinking and much more. Our goal is to work with you to develop Cmk/Cpk-capable processes as part of an SE project (simultaneous engineering). Of course, we are also your partner when it comes to improving existing processes. Our aim is to adapt your proven manufacturing process to new requirements. We focus on efficient and smooth integration into production.

As a system supplier, we offer you state-of-the-art contract coating including continuous improvement of systems and processes. Your advantages: Your coated products are immediately available with high quality. You do not have to invest in structural measures, production and operating resources, and there is no need to invest in knowledge acquisition, employee training or operational practice. Whether small or large series production - all machines, components and processes are certified according to ISO and QM standards of the industry. We manufacture according to comprehensively documented technical standards and regularly undergo internal and external audits. This ensures traceability at all times.

Our system technology follows the requirements of our time. In a digitally networked production, you can evaluate process data as you wish and optimize your production process. We provide new technologies for you. The focus is on the seamless integration of our systems into your existing production processes with an effort that you can calculate.

We want you to be able to manufacture your perfectly coated products in the best possible way at all times. With our tailor-made training courses on site or as part of our coating academy, your employees will be comprehensively trained. With professional inspections by our experts and fast maintenance and repair services, you can produce efficiently and safely today and in the future. Because with Bosch you not only have excellent products, but also competent contacts at your side at all times.

Wherever high-performance layers are required, PVD and CVD processes are generally used. With the help of chemical or physical vapor deposition, not only extremely thin layers but also extremely hard diamond-like carbon layers with very low coefficients of friction can be produced using this vacuum-based process. The production of heavy-duty ceramic wear protection layers, which are specially designed for impact wear, is also possible with this method without any problems.

Thermal spraying refers to a universally applicable surface coating process in which a wide range of different coating materials can be melted on or surface-fuse by using thermal energy. This is done by applying the coating directly onto the component using high kinetic energy. Thermally sprayed layers enable electrical insulation and also effectively protect highly stressed components from external influences such as corrosion or wear, making your components significantly more durable.

Galvanic deposition can be used for a variety of applications and includes both the coating of complete component surfaces including internal geometries and the partial coating of defined areas. Galvanic coating is an optimal solution, especially for applications with combined functions such as wear or corrosion protection. Depending on the requirements, cost-effective coatings can also be implemented in variable quantities.

Conversion layers are non-metallic, inorganic layers on metallic surfaces that are created by a chemical process and form a particularly good adhesion base for subsequent coatings. They also serve as corrosion protection and running-in layers for tribologically stressed components.

Anodized surfaces are special and technically particularly important conversion layers, as they serve to build up or reinforce an already existing oxide layer on light metals such as aluminum or titanium. Wear resistance, corrosion protection as well as thermal and electrical insulation are significantly improved.

Dipping, doctor blading and spraying are usually simple and inexpensive methods for coating with liquid materials such as paints, silanes or sol-gel materials. They all form functional layers that strive to improve corrosion protection, increase electrical insulation and create optically attractive surfaces in different shades. Silanes can also be adjusted in a targeted manner by surface modification or functionalization of the side chains (e.g. via alkoxy or fluoride-containing groups) in the direction of wear protection, corrosion protection or wetting behavior.

As an expert in surface technology, we can select suitable wet-chemical pre-treatments and polishing steps with you. Whether roughening, smoothing, cleaning, deburring or electropolishing, we develop the process and the associated system technology to optimize your product and your processes.
