Metalworking: minimising dust, fumes, etc.

In order to be able to process metals, various procedures such as welding, grinding, polishing, coating, painting, cutting with lasers and plasma or metal-cutting manufacturing procedures are used. All of these procedures have one thing in common: emissions occur in the form of fine dust, dust, fumes, gases and vapours that are harmful to health and could also have a negative effect on product quality. In order to keep the load of these emissions as low as possible, Scheuch LIGNO has a suitable extraction solution for each procedure in its range. Welding fume extraction, painting systems for surface treatment and many other solutions always guarantee optimised working and production conditions for metalworking.

Optimum working and production conditions

Many harmful emissions occur in the metalworking industry. Due to the severe lack of experts in the metals industry, it is increasingly difficult for companies to find new staff. Providing a clean working environment not only increases productivity and improves staff health but also piques the interest of new experts. Scheuch LIGNO is a pioneer in extraction cleaning system and has developed highly specialised expertise in these areas thanks to its years of experience. Our entire team is highly motivated and committed to guiding the sector into an environmentally conscious future.

Surface technology plays a decisive roll in the metalworking industry, as it guarantees the highest quality standards and offers effective corrosion protection. Surface treatment of metals offers numerous procedures with the aim of improving, protecting or changing the external quality of metal parts. The basic prerequisite for perfect surfaces in the metals sector is clean working conditions, which can be achieved by optimised filtration and extraction solutions in spray booths for example. Paint adhesion problems, long processing times or quality issues are the greatest challenges for our customers. Scheuch LIGNO GmbH is happy to advise and support you with process optimisation for worry-free surface technology.

Particularly in surface treatment in the metalworking industry, there are numerous processing procedures. In order to find the right solution for every processing procedure, Scheuch LIGNO GmbH offers a wide range of tailor-made solutions.

This positive substance joining procedure is used to join metals using the effects of heat and to produce complex components. The fume emissions that occur when welding are extremely harmful to health, as the emissions contain multiple particles of various sizes, normally smaller than 1 µm. These particles can contain poisonous metals such as lead, copper, nickel and zinc depending on the material and the welding procedure. Various gases such as carbon monoxide, nitrogen oxide, ozone and volatile organic compounds occur in welding fumes. These gases can cause respiratory irritations and other health problems.

The filter cartridges used by Scheuch LIGNO have been developed especially for removing fine fumes during the welding process. They guarantee and extremely high filtration efficiency of over 99 %, which contributes to a pleasant working environment in any production hall.

Grinding is a cutting procedure with geometrically undefined cuts. The excess material is stripped using manual or automated grinding machines. Therefore, even the hardest materials can be processed. When processing materials, large quantities of dust occur, which may be carcinogenic, flammable or explosive depending on the material.

Grinding causes fine dusts and particles that can spread throughout the production hall quickly. The Scheuch LIGNO GmbH grinding booths collect all grinding particles and filter them effectively, regardless of whether these are explosive materials or normal steel dusts. The Scheuch LIGNO solutions are tailored exactly to each customer’s requirements in order to guarantee optimised collection and filtration.

Flame and plasma cutting is a thermal cutting procedure to cut metal. This releases a high concentration of particulate substances. These flam cutting fumes may contain numerous poisonous chemicals such as carbon monoxide, nitrogen oxide and benzene, which are harmful to health if inhaled.

Imagining the metalworking industry without flame and plasma cutting is no longer possible. The flame and plasma cutting systems are often operated in shifts and are some of the greatest hall polluters in the production hall. Thanks to the tested filter systems from Scheuch LIGNO with their long filter service lives, even these quantities of vapour emissions are collected and filtered efficiently.

The applications for lasers in metalworking are numerous. The metal is cut using a laser beam. Laser cutting does not cause fumes but does cause low quantities of dust and vapours due to the high temperatures.

Even low quantities of dust and vapours can have long-term health consequences. In order to prevent laser fume emissions spreading, Scheuch LIGNO offers tailor-made solutions to capture the emissions that occur directly at the source. Scheuch LIGNO solutions aim to prevent harmful substances spreading and therefore to protect employees’ health. We develop targeted collection systems to guarantee efficient and controlled extraction of these laser fume emissions.

In metal-cutting manufacturing procedures such as fully-automated CNC machines or normal drilling work, emulsions are used to improve the machining quality and the service life of the tools. Emulsion mists therefore occur, which could harm the employees’ health.

In order to counteract these challenges, Scheuch LIGNO GmbH offers specially-designed filters that filter even the smallest contamination efficiently. Scheuch LIGNO solutions guarantee a clean working environment and contribute to retaining the processing machines for the long term. Thanks to the effective filtration, the employees’ health is protected and the machine’s service life is increased at the same time.

Mechanical surface treatment includes procedures such as sanding, brushing or polishing. In order to guarantee quality requirements or corrosion protection, the metals often have to be treated mechanically. This procedure causes the finest dust particles that spread throughout the production hall and cause health problems. The Scheuch LIGNO GmbH grinding booths provide a clean and healthy working environment.

Painting is commonly-used procedure in which a layer of paint or varnish is applied to the metal’s surface. This can protect the metal from corrosion and also produce aesthetic improvements. The most modern filter technology in the Scheuch LIGNO GmbH painting systems complies with the strictest environmental regulations and quality requirements.

Here, a layer of different materials such as plastics, ceramics or metals are applied to the metal’s surface. This procedure can be used to improve the metal’s mechanical, chemical or visual attributes. The Scheuch LIGNO GmbH product range also offers solutions for this procedure.

From the painting system to the complete production process. Scheuch LIGNO GmbH considers every single customer’s problems and offers solutions for the entire surface process. In order to ensure a smooth coating process, conveyor systems are installed in conjunction with painting and drying systems to shorten the processing times. The conveyor system can be designed to be manual, automatic or semi-automatic and include lifting and lowering stations.

Drying rooms play an important part in surface treatment and are used to provide a controlled environment for drying painted surfaces. These rooms provide various benefits and are essential for high-quality, durable painting work. Scheuch LIGNO GmbH optimises the drying process and helps customers to minimise their drying times.
