GRONBACH - Industrial Metal Processing and Machining

Main page » Technologies » Industrial metal processing

Our high-performance equipment and our staff’s experience, gained over many years, enables us to implement almost any geometrical form in the field of industrial metal processing – from single functional parts for the furniture fittings industry, such as frames or mountings, to sophisticated design parts such as automotive door sills, fascia panels for dishwashers or drip trays for coffee machines. We have modern and efficient equipment and installations for all of this range of applications and different sectors. The production of a wide range of mechanical components is characterised by dimensional accuracy and durability as well as a high level of operating convenience. Our products can be used in visible areas and as turnkey functional components.

Household appliances (hinges, handles, frames, fronts, pull-out systems, OEM appliances, roll holders)
Furniture industry (citchens made of aluminium, handles, frames, drawers, shelving systems, design elements)
Lighting industry (basic elements, design elements)
Sanitary industry (shelves, holders)
System gastronomy (doors for steam ovens, doors for microwave ovens, sinks, cookers)

Tool-making

Our tool-making workshop produces high-precision tools, using top-quality steel, up-to-date techniques for heat treatment, and surface finishing, as well as incorporating standard components from leading manufacturers. Together with our engineering department, we design and produce stamping and forming tools for visible components, progressive compound tools and injection-moulding tools along with the appropriate handling equipment.

We provide testing procedures for the tools in our production department along with mould-flow analysis and numerical simulation techniques for injection-moulding tools. When required, we create one-off testing equipment to ensure that quality remains continuously high during serial production.

Development and Engineering

Our experienced designers and engineers create and implement the wishes and ideas of our customers on schedule and cost-effectively – from single components and assemblies through to complete appliances. Our development department designs ready-for-production components and assemblies, which ensures an optimised workflow. We conduct analyses to identify potential for improvement and study various constructional options and the degree of flexibility.

The following points summarise what we are able to offer:

Consultation and concept development
Draft and detailed planning
Design in 2D and 3D including animation
Support for all CAD-interchangeable formats (DXF, DWG, iges, sat, Step, …)
Production optimisation
Development of manufacturing equipment

Bonding Technology

Alongside classical bonding techniques, industrial bonding technology in the field of metal processing represents an important pillar within the range of our technological spectrum, as it enables us to combine the most diverse of materials in all possible variations with each other, e.g. metal-glass, synthetics-glass, metal-synthetics. Our equipment is of the highest technical standard and in many cases is automated, enabling us to achieve perfect, reproducible results.

Our processes use:

1K-adhesives applied manually or robot-assisted
2K-adhesives in robotic systems with high-end dosage technology
Adhesive tapes applied manually and/or robot-assisted
Stamping-bonding support equipment with unique technology for perfect positioning and pressing
Surface pre-treatment depending on the application using adhesive primer, flame treatment, plasma or pyrosil
Quick drying using heat, infrared or UV radiation

ASSEMBLY

Assembly processes are an important dimension of our manufacturing philosophy. Lean production, demography and ‘Industry 4.0’, as well as our well-known quality methods, are important factors in the organisation of our working procedures. To ensure the health and performance levels of our workforce and the consistent quality of our products, we pay great attention to ergonomics; from the individual work places, the related flexible workflow systems and capacity, and the fully automated production installations. Focussed professionals and optimised manufacturing processes lead to robust and fault-free results with systematic and precise reproducibility.
