Plating describes the process of applying a firmly adhered layer to a substrate. The aim of plating is to positively influence the properties of a substrate both chemically and physically. An important criterion for assessing the quality of plating is its adhesive strength, which characterises how well the applied layer adheres to the substrate.
This parameter can be greatly influenced by treating the substrate with an angular blast media. The blast process roughens the component, and the resulting surface finish ensures a considerable improvement in adhesion, thereby significantly increasing the quality of the plating.
Clean water is the basis of all life forms.
Multi-layer filters make a valuable contribution in significantly improving the cleanliness and quality of contaminated water.
Due to its hardness, high bulk density and chemical stability, garnet is an important component of a multi-layer filter. Garnet extends the service life of the filter system and ensures a stable and high filtration rate.
Flooring / Anti-Skid
In accordance with the relevant trade regulations for non-slip flooring at work, floors must have sufficient slip resistance in all industries and environments. Equally, it must be ensured that sufficient displacement space is achieved so that aquaplaning hazards are reduced.
Foundries are high-performance centres in which castings are manufactured from a wide variety of materials for numerous industries. They undertake work ranging from complex individual parts to mass production.
Many casting processes require a uniform surface finish at the end of the machining process. The desired performance is achieved through targeted surface treatment which meets the high requirements in terms of dimensional accuracy, mechanical stress and surface quality.
Essential for an effective surface treatment process which guarantees the desired surface finish is the choice of a suitable abrasive.
The term laminate refers to a floor or decorative covering consisting of several layers. The overlay or top layer functions as protection for the laminate from everyday wear and tear. To ensure the desired abrasion resistance, fused alumina is added to the adhesive of the overlay.
Our premium quality aluminium oxide has become particularly well established, fulfilling not only the special requirements for abrasion resistance and transparency, but also the required degree of whiteness. The extremely high purity allows an unobstructed view of the decorative paper of the laminate.
Surface technology is an important factor in the maritime sector. The ever-changing weather conditions place special demands on the slip and abrasion resistance of ship deck coverings . At the same time, it is important to ensure the corrosion resistance of the coatings and of other components which are exposed to constant weathering. These special requirements can equally be met by correct pre-treatment and subsequent coating with high-quality blast media from Kuhmichel.
Masonary Cleaning | Building Restoration
Buildings are exposed to constant environmental influences and pollutants, which sooner or later lead to weathering. The result is soiled and discolored surfaces which are visually unattractive.
A cost-effective, environmentally-friendly, chemical-free solution is to clean buildings with the help of blasting media.
This removes all types of contamination whilst keeping substance loss on the substrate itself as low as possible.
Medical technology is characterised by its stringent demands on both man and machine. This area requires an uncompromising approach and complete transparancy in the documentation of all processes and products.

Steel And Metal Construction
Many forms of blasting are used in the steel and metal construction industry.
Often blasting is the only economical solution when it comes to achieving the desired component properties.
These properties include the fulfilment of specified purity and roughness values, component hardening (shot peening) and deburring.
The variety of applications, specifications and system technology require a specific selection of blast media, which function as a tool to provide the desired surface finish.
In the stone industry, the areas of application for surface treatment are very varied.
From smoothing stone surfaces to optical refinement;
from engraving of all kinds to the processing of floor slabs to improve anti-slip properties; abrasives play an important role in achieving the desired end result.
Tools undergo a multitude of machining steps from production to completion.
Their surface treatments are as individual as each tool is for its designated application.
Tool applications include descaling and deburring, as well as roughening as a pre-treatment to improve adhesion of a subsequent coating.
The use of abrasive media for surface treatment plays an important role in the manufacture and maintenance of rail vehicles, components and infrastructure. The properties of components can be significantly improved by specific treatments. Blasting is used to prepare surfaces for subsequent coatings, and to increase the service life of workpieces.
