High-Performance Presses S - Efficient, highly precise & energy saving.

The Presses S are high-performance versions of the COLLIN presses. The S series for servo hydraulics convinces by its ergonomic, space-saving and modern design – the efficient servo hydraulics by its quiet operation, the highly precise pressure control and a low energy consumption. Moreover, due to this concept, cooling water is no longer required.

Flat Film Lines with 3 rolls – smoothing calender & chill roll - Smoothing, embossing, laminating of films & sheets.

These COLLIN flat film lines combine smoothing calender and chill roll and are used in the production of thin-walled or thick-walled films. The 3-roll unit can be used for vertical or horizontal operation – the roll group can be swivelled by 90 degrees. The forces in the smoothing gap can hydraulically or pneumatically be generated. The smoothing roll is suitable for a wide selection of applications such as smoothing, embossing or laminating.

COLLIN Medical Line: Production of multi-layer multi-lumen resp. plastic hoses for medical applications

In modern medicine, a nearly immense variety of hoses is used. Examples for their field of application are hoses for invasive surgeries, dialysis hoses, infusion hoses, catheter hoses, drainage hoses etc. The range of diameters reaches from thinner than a human hair (Up to 7 separate channels in one multi-lumen hose
„The inner geometry of the hoses ranges from mono-lumen up to multi-lumen hoses containing up to seven separate channels. It is clear, that all geometric parameters are extremely narrowly tolerated. This geometric variety is multiplied by using different plastics “, explains DI Dr. Friedrich Kastner, CEO / Managing Partner COLLIN Lab & Pilot Solutions.

Depending on the application, five-layer design by coextrusion
„This ranges from PVC with special plasticizers via polyethylene, cross-linked PE, silicone rubber, thermoplastic polyurethane, polyamide up to fluoroplastic. Of course, also coextrusion is used by using up to 5 layers in order to increasingly adapt the property profile of the hose to the requirements of the field of application “, says Thomas Nick, Sales Director Medical Line COLLIN Lab & Pilot Solutions. „Furthermore, there is the combination of polymer material with metal support bodies with different geometric characteristics. “

Flexibility, precision & clean room conformity necessary
To an increasing degree, there are also requirements of variable diameters in longitudinal direction or different materials which are strung together at short distances. It is obvious that in such an environment, highest requirements regarding flexibility and precision of an extrusion line have to be fulfilled.

Beside these characteristics, it has to be noted that clean room production requires the use of special materials. Abrasion, release of dust, lubricants or vapours, which can cover the product have absolutely to be avoided. Moreover, it is necessary that there is easy access to all product-guiding line components in order to guarantee easy cleaning.

Safe documentation of process-relevant process parameters
Beside technical requirements for the production of high-precision hoses, also the control of such a line has to fulfil further characteristics: Here, the documentation of all process-relevant process parameters should especially be mentioned. These have to be recorded and stored in such a way that a manipulation of the data can safely be excluded. This requirement results in complex measures in the control software.

Beside the technical requirements of the line, also the FDA (Food and Drug Administration) standards have to be met. For that purpose, special know how is required, especially regarding the very strict documentation principles during the complete production phase of the line.

Essentially, it is divided into

  • Design Qualification DQ
  • Installation Qualification IQ
  • Operation Qualification OQ
  • Process Qualification PQ

The latter is not made at the manufacturer of the line but at the user.

Market leader with more than 45 years of experience
COLLIN Lab & Pilot Solutions, certified according to ISO 9001:2000, has been manufacturing high-precision and compact extrusion components and lines for laboratory and pilot applications for more than 45 years. This market segment requires machines and lines which can be used very flexibly under continuously changing edge conditions. As market leader in this field, all necessary pre-conditions are given to develop and successfully commission lines for the production in the medical sector.

Beside a number of special roll mills for the pre-development and production of pharmaceutical products, also lines for the production of IV bags, medical sutures and wound dressing are manufactured. The latest development is a production line for the production of medical face masks.

COMPOUNDING – BLACK MAGIC, ALCHEMY OR EXACT SCIENCE?
Read more in the COLLIN TECHNEWS 3.

Just nowadays, we are experiencing that there is a change in plastic industry. Plastic generates negative headlines again and again – from micro plastic up to plastic islands in the sea. Therefore, the topic recyc-ling becomes even more important and a burning issue – in R&D, for mechanical engineering companies or for the plastic processing industry.

In order to facilitate the recycling of polymers, the material has to be more homogenous and compatible. This, in turn, offers for companies for example the option to refeed the pellets, recycled via inhouse recycling, into the production process – and thus the own energy footprint can be improved.

Here, compounding is often the technology of choice.
Additives and fillers are incorporated into the plastic mass in order to create new characteristics. For this purpose, COLLIN offers solutions for simple to highly complex applications, which can directly be integrated into blown or cast lines. Instead of an extruder, a compounder is used, which degases the plastic and mix it with different additives. Among other things, compounding is suitable for packaging and technical or medical products.

For customers of the NGA Group, it is an advantage that the group covers the complete life cycle up to recycling: NGA does analysis and simulation, COLLIN is international pioneer in the field of compounding technology resp. product develop-ment and BritAS bolt screen changers are the perfect solution for the processing of plastic waste to pellets.

A press is not a press - COLLIN High Performance Solution - efficient, highly precise & energy saving

he customer wants to cool down by 15 K/min according to the ASTM 4703 (former 1928) for certain Polyolefins.

BUT it is not only cooling down by 15 K/min. It also needs to be controlled in a tolerance of +/- 2 K from 150° K to 90° K measured every 30 sec.

The press S servo hydraulics from COLLIN Lab and Pilot Solutions offers this accuracy, since this is very important for the density. By not controlling this cooling rate with such an accuracy, there could be variations in the density. The picture below shows the actual value and the set value.

In the market, there are many presses, which all can cool down by 150° K to 90°, but most of them are just swivelling around the cooling down line.

Besides that, the press has the following features:

  • Low noise servo hydraulic system
  • No oil cooler needed –> lower cooling water consumption
  • Pneumatic low pressure stage for the range of 0.1 to 2 bar
  • Reduced energy consumption
  • Pressure regulation via the motor rotation speed
  • Temperature range: 20 – 350°C (up to 450°C as option)
  • High temperature accuracy of +/- 1.5°C over the platens measured at 9 points
