Cleaning and Pre-Treatment of Machine Components

Space-Saving Solution with High Standards of Cleanliness

Weber Ultrasonics GmbH

Ultrasound systems with different frequencies are often used in the optics, precision engineering and electronics sectors and for precision cleaning in other areas. Multi-frequency systems keep the space needed by ultrasonic cleaning machines to a minimum. PDF-Download

Effective Removal of Particles and Machining Oils

Karl Roll GmbH & Co. KG

In order to meet cleanliness requirements, which include the absence of particles larger than 500 μm and the ability to bond and coat the surface, using a cost-effective and reliable process, a manufacturer of cold extruded parts invested in several identical perchloroethylene cleaning systems.

Precise Settings for Coating Parameters

Clemens Kubeil

It is not possible to investigate adequately every individual parameter that influences electrochemical processes. This is where numerical simulation comes in. It allows complex interrelationships in electrochemical cells to be recorded and represented and it also provides support for developing and managing procedures and processes. PDF-Download

Reliable Crankshaft Descaling

Rösler Oberflächentechnik

To ensure an absolutely scale-free surface, crankshafts forged at ThyssenKrupp Gerlach undergo a blast cleaning process. For this purpose, the company invested in an innovative shot blasting system. Integrated into a fully automatic production process, this blasting machine is used for the optimised descaling of 150 different crankshaft types. PDF-Download

Combined Painting Robot and Spray Painting Machine

Venjakob Maschinenbau GmbH & Co. KG

This newly developed system allows parts with complex edges to be painted perfectly in one pass. The machine can be structured to suit the operator’s needs. PDF-Download

Reduced Powder Consumption and Higher Throughput

Karl Bubenhofer AG

The Swiss company Bigla manufactures high-quality office furniture with a modern and practical design. The company recently switched over to an ultra-thin powder coating, and the result was a significant reduction in powder consumption and an increase in plant capacity. PDF-Download

Anti-Graffiti Powder Coating with a High Level of Protection

IGP Pulvertechnik AG

A new anti-graffiti powder coating which is highly resistant to chemicals has been developed specifically for indoor applications. A version of the product is also available with antimicrobial properties. This opens up a number of new applications in areas where high standards of hygiene are required. PDF-Download

No Heavy Metals, No Heating and Small Quantities of Sludge

Tobias Distler

Many different metal pre-treatment procedures and products are now available which are much more environmentally friendly and use significantly fewer resources than their predecessors. Considerable savings can be made on the costs of energy, water, waste water and maintenance. PDF-Download

The Ideal Solution when the Going Gets Tough

Marcus Allig

Automated systems are increasingly being used in the automotive industry to apply sealants and noise insulation materials. A new generation of modular high-pressure pumps and regulators offers both high flow rates and ease of maintenance. PDF-Download

Precision Cleaning with Modified Alcohol

Markus Mitschele

A vacuum parts cleaning machine has been developed for the Chinese company Shaanxi Elektro Ltd. to clean components for the final time before assembly. The main requirements for the cleaning process were a maximum particle size of 100 μm and a surface tension of at least 42 mN/m. PDF-Download

A “Smart” Paint Shop

Gerald Scheffels

The Smart production facility at the Daimler plant in Hambach in France officially opened its new paint shop in May 2013. This is the second Daimler plant to use the IP2 process, which dispenses with the need for primer and consists of the wet-on-wet application of water-based paints. The new paint shop, involving an investment of around 50 million euros, has reduced energy consumption at the plant and has been operating reliably since it was commissioned. PDF-Download

Cleanliness Inspection Directly at the Process

André Lohse

The basic requirement for high quality surface coatings as well as bonded or welded joints is sufficient cleanliness of part surfaces. An efficient fluorescence measuring technology allows parts’ control directly at the process. PDF-Download

Excellent Corrosion Protection from a Single Coat

Alexander Schelling

In a recent study, the influence of the curing conditions on the corrosion protection properties of coatings on a number of different substrates was investigated. In addition, powder coatings which provide corrosion protection of at least category C4 medium with a single coat were identified. The objective was to find alternatives to the widely used primid systems that provide significantly improved protection against corrosion in the low-temperature range. PDF-Download

Fast Colour Changes Bring a Rapid ROI

Gema

A new manual coating system enables all colour changes to be made in less than one minute. It has been thoroughly tested by a specialist powder coating company. PDF-Download

Controlled Discharges

Brillux Industrielack

One method of protecting electronic components from unwanted electrostatic charges, which is not only safe and reliable but also easy to use and cost-effective, is by applying a conductive ESD mixed powder coating. PDF-Download

Low-Temperature Coating for a Range of Applications

Ganzlin

Today’s powder coatings need to offer high levels of corrosion resistance, a broad palette of colours, short delivery times and low curing temperatures. A newly developed low-temperature polyester powder with a fine texture and a matt finish, which also has Qualisteelcoat certification, meets all these requirements. PDF-Download

Coating Sun Protection Systems Efficiently and Accurately

Nordson Deutschland GmbH

By investing in a modern powder coating machine, a leading manufacturer of sun protection systems was able to reduce its reject rate significantly, increase its productivity by 25% and reduce colour change times from 40 minutes to 10. This article describes the new system and reports on the operator’s experiences. PDF-Download

Stripping Thick Coatings with Lasers and Eddy Currents

Clean-Lasersysteme GmbH

Until now, laser cleaning processes have been restricted to use with thin coatings. Extensive laboratory and practical tests have now shown that a combination of a laser system and an induction process is effective in removing paint and epoxy-based coatings with a thickness of up to 25 mm.
