Avoid errors – Clean more economically

Avoid errors – Clean more economically

01/05/2012

In addition to the utilised system, other factors also play a role in producing the required cleaning results reliably, quickly and efficiently – from the selection of suitable cleaning agents, the cleaning rack and bath maintenance, right on up to packaging the cleaned parts.

It costs money to clean workpieces and surfaces. How much effort is required depends to a great extent on the specified cleanliness requirements. But regardless of whether simple degreasing or a demanding cleaning task with residual contamination limits is involved, an holistic view of the entire process sequence not only makes it possible to reduce costs in most cases, but rather quality can be increased as well.

Cleaning as a step in the manufacturing process – Interaction amongst many factors

Ideally matching the cleaning system and process technology to actual contamination, the specified cleanliness requirements and production throughput is absolutely essential. And it’s advisable to differentiate between cleaning systems which will be used for pre and intermediate cleaning, or for fine cleaning. If a system designed for fine or micro-cleaning is used for other tasks, the user runs the risk that contamination deposits will accumulate in the system and subsequently end up back on the fine cleaned parts.

If aqueous cleaning systems are operated with tap water, substances contained in the water may cause problems for the cleaning and rinsing processes. Water hardness and salt content play an important role. Increased overall salt content may result in precipitation of limescale, lime soaps, phosphates, silicates, tensides and corrosion inhibitors. Possible consequences include reduced cleaning action and corrosion protection, as well as spots on the parts. Suitable water treatment eliminates this problem.

Quality and duration of the cleaning process, as well as how much energy it consumes, depend decisively on the utilised cleaning rack as well. Neither a spray jet nor ultrasound can release its full effect through a closed or perforated sheet metal box, nor can the cleaning agent rinse the parts thoroughly from all sides. However, this is imperative for good cleaning results. Ideal parts accessibility and material compatibility are provided by cleaning baskets made of stainless steel round wire. These are further distinguished by significantly better draining characteristics, resulting in considerably less carry-over of contamination and cleaning agent than with closed or perforated boxes. Wire baskets also allow for a shorter, energy-saving drying process.

Bath maintenance components which have been too meagrely dimensioned or incorrectly laid out for the cleaning task (e.g. oil separators, particle filters and membrane filters) quickly lead to the accumulation of contamination in the bath, and thus to poor cleaning quality. Frequent bath changes and the associated increases in cleaning agent, energy and water consumption (if applicable), as well as growing quantities of refuse and wastewater, drive operating costs up. A minimum amount of monitoring is also required in order to assure a trouble-free and economically efficient cleaning process over the longest possible period of time. For example, this applies to cleaning agent concentration, water quality, bath fill-level and filter condition. A handling process which has been adapted to the specified cleanliness requirements and suitable packaging prevent recontamination of the parts after cleaning.

Complete programme for efficient and reliable cleaning

As the world’s only trade fair focused exclusively on industrial parts and surface cleaning, parts2clean not only presents the products and services required in order to optimise the imperative cleaning step, it offers the necessary know-how as well. The exhibition portfolio of the leading international trade fair encompasses systems and processes, as well as process media and their conditioning, for degreasing, cleaning, deburring and pre-treatment of parts, parts baskets and workpiece carriers, handling and process automation, cleanroom technology, job-shop cleaning, quality assurance, test methods, analysis procedures, temporary corrosion protection, preservation, packaging and technical literature.

parts2clean will offer a complete overview of processes, procedures, media and measures for cost-efficient cleanliness in accordance with specified requirements in manufacturing and MRO processes from the 23rd through the 25th of October, 2012. Beyond this, the expert forum held at the leading international trade fair will provide simultaneous interpreting for presentations in German and English for the first time at the 10th parts2clean. The presentations will offer lots of knowledge and know-how covering all aspects of industrial parts and surface cleaning.

The 10th parts2clean will take place at the Stuttgart Exhibition Centre from the 23rd through the 25th of October, 2012. The parts2clean expert forum, which has established itself as a valuable source of knowledge and is in great demand, will be held at the anniversary event in both German and English for the first time.
