Topic: Avoid Errors – Clean More Economically

Contaminated parts go into
a system at the front, and they come put clean at the back – a nice idea which
doesn’t work in actual practice. 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.
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.

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

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. 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
