Comprehensive solutions from a single source

In the field of innovations, DIA-Nielsen has set itself the task, with its extremely high manufacturing depth, of providing comprehensive solutions for individual products.

To give you a better insight into our manufacturing depth, these must be broken down into the individual process phases, in order to demonstrate to you how we handle the procedure from the concept stage right through to the individual packaging.

But first, there is an important question to be answered:

What can we actually do?

The classics

These and other products have been manufactured by DIA-Nielsen in thousands of different variants since the founding of the company. The so-called disposable nibs and printheads have been jointly developed for the world market in cooperation with all leading manufacturers of recording measurement devices, and we continue to market them successfully to the present day.
All individual parts are designed and produced in-house.

Dealing with lemons...

...does not come into the question if you talk to us about the production of thin-walled, geometrically complex plastic components. Whether this is a matter of narrow, thin-walled chambers, or a special tool concept for the production of a component from a single moulding in order to avoid costly assembly – our design and injection-moulding department specialises in such details. This has grown up out of the concept of the simple writing system, and has been developed further over the years by increasingly specialised and demanding solutions.

Seven times thinner than a hair...

...this is the size of the tungsten wires which we mould into plastic in this series component. This master stroke became necessary in order to meet the increasingly exacting requirements in the area of ink control systems. We readily accepted the challenges of developing the necessary modifications to the handling devices and injection-moulding machines. This component was able to go into series production before the end of the project time.

Anything but peanuts

Whether components for an artificial heart for pigs, or highly complex units for centrifuge filtration with welded-in filtration membranes – our “new” products naturally have the same claim to innovation as our classics. The knowledge of the ultrasound welding procedure coupled with the know-how of the plastic injection-moulding process lead, in the filtration unit for example, to a successful new concept of horizontal filtration. With design, tool construction and assembly – as usual – all from a single source.

Gears – The freestyle in tool construction

We completed a technical master stroke in the production of various gear drives for ventilation systems of explosion-protection systems. The problem in this special application was the design of multiple gears with up to four cogs which are moulded in a single process, in which all the individual cogs comply with strict concentricity and gear tolerances. Particularly noteworthy is the fact that these consisted of weight-reduced hollow gears, which using insert technology form a permanent connection with metal shafts and metal gears.

Groundbreaking

Long, thin-walled sleeves, whose tips must be closed. Although this component may look unspectacular, any specialist will immediately guess what pitfalls we had to avoid, in order to produce such a thin-walled (0.1 mm), long (100 mm) component completely tight at the tip using the injection-moulding process. It is (almost) impossible to produce such parts absolutely straight and without distortion. The exact knowledge of the flow paths and speeds are absolutely essential here, although success requires a particular further trick. And this is exactly what constitutes the difference between the standard solutions and our solutions - “The Intelligent Alternative”.

Penny-pinchers...

...we are still, even in the age of the €-Cent – but only when it comes to the size of some components and the rounded-down offer price. Nor are we mean when it comes to technology and implementation. This filter element for a blood-pressure measuring device is just one small example of our capabilities of fitting filtration membranes of all types into components of all sizes.

Smile

Of course you can also buy syringe preliminary filters from other well-known competitors, although you don’t have to. Especially if your ideas and needs do not correspond to the mass product, we can assist you with our flexibility. All standard membranes are of course included in our portfolio in the standard filter sizes 15, 25 and 30 mm, further processed in the clean-room also in sterile versions on request. But we will really be able to bring a smile to your face if you need special solutions for your personal requirements. This ranges from special membranes, to special sizes and geometries, and on to special colour codings and imprints or any other special requirements.
