COLLIN tube lines are used for the production of multi-lumen resp. plastic tubes for medical applications, also multi-layer.

The spectrum of diameters ranges from thinner than a human hair (<100 µm) up to approx. 5 mm. By means of coextrusion, the properties of the tubes, with a design of up to 5 layers, are adapted to the requirements of the field of applications.

The inner geometry of COLLIN MEDICAL LINE tubes ranges from simple mono-lumen up to multi-lumen tubes, which contain up to seven channels, which are separated from each other. It is clear that all geometric parameters are extremely, narrowly tolerated. This geometric variety is multiplied by using different plastics.

Furthermore, polymer materials can be combined with metallic supporting bodies with different, geometric characteristics.

Advantages

• Up to 5 layers

• Up to 7 separate channels

• Enormous variability in production

• Continuous production, compliance with all tolerance requirements Lines, which can produce around the clock

• Highly tempered stainless steel (316L) for all product-touching parts Standard-compliant surfaces

Applications

• Minimally invasive surgeries

• Dialysis tubes

• Infusion tubes

• Catheter tubes

• Drainage tubes

• etc.

These versions combine finishing calender and the chill roll and are used for the production of thin-walled or heavy-wall films. The 3-roll unit can be used for vertical or horizontal operation.

The forces in the polishing gap can be created in a hydraulic or pneumatic way. The polishing roll is suitable for a wide range of applications such as smoothing, embossing or laminating.

The COLLIN Press Type S integrates several advantages of the COLLIN presses – and it is particularly impressive by its practical, quiet hydraulic, modern design and the vertically moveable door. Especially the good cleanability and the materials that conform to medical standards are convincing.

Exemplary applications

• Clean room technology – Design for the production of medical or pharmaceutical products

• Quality control of materials

• Production of test sheets / samples

For medical technology, pharmacy as well as food (also pet), the Medical Line Extruder presents itself as compact and modular. The machines can be used in various ways as they are powered by an innovative concept. Many different types of downstream equipment can be connected and numerous additional equipment as well as features can be realised.

Exemplary applications

• Multi-layer strand production

• Mono & multi-lumen hoses

• Mono & multi-layer applications

• Hoses for coronary invasive therapy

• Catheters

The COLLIN MEDICAL LINE Compounder is used for a variety of applications in the pharmaceutical and medical sector. Due to the compact design, the lines are easy to clean and it takes extremely short periods of time to change the material.

Exemplary applications

• Incorporation of active agents in carrier materials

• Degassing of volatile components

• Pelletizing of tablet premixes

• Mixing and dispersing of pigments

• Incorporation of solid and liquid additives

• Incorporation of organic and non-organic fibres

• Blending of polymers and pastes

• Continuous reactive extrusion

Compact design with small floor space, easy operation and accurate, reproducible positionings as well as quick changes of products and parameters are what makes COLLIN blown film lines so unique.

They are used for function tests of polymers and compounds, for the development of multi-layer films, the quality con-trol of the pigment dispersion, the control of the dispersing behaviour of compounds and extruders or for the production of small film hoses in the food or medical sector.

Blown film lines with air cooling of the film

Blown film lines with a diameter of 20 to 120 mm are suitable for the production of hoses with lay-flat widths of up to 790 mm.

Blown film lines with water cooling of the film

These COLLIN lines are used for the production of infusion bags or other mono or multi-layer products. Vertical extrusion into a water cooling ring delivers optimal film transparency, e.g. suitable for PVC-free infusion bags or blood plasma bags.

These versions combine finishing calender and the chill roll and are used for the production of thin-walled or heavy-wall films. The 3-roll unit can be used for vertical or horizontal operation.

The forces in the polishing gap can be created in a hydraulic or pneumatic way. The polishing roll is suitable for a wide range of applications such as smoothing, embossing or laminating.
