Module lines are used in the packaging sector for the production of multi-polymer compounds, e. g. with carrier materials. The system allows the integration of different modules such as flat film, blown film and calendering unit as well as miscellaneous additional equipment, e. g. Corona pre-treatment or additional unwinders.

Custom-made solutions can be delivered for the following applications:

• Flat film extrusion

• Blown film extrusion

• Smoothing – Embossing

• Extrusion coating

• Laminating

• Take-off speed up to 200 m/min

• Roll position mutually adjustable in x and y direction

• Good accessibility

Press Type S particularly convinces with its quiet hydraulic aggregate, which does not run constantly. Moreover, no oil cooler is needed, resulting in a lower consumption of cooling water. Combined with an optional chiller, which is adapted to the press, a cooling water consumption can almost completely be avoided.

An additional advantage is the pneumatically, vertically movable door. Optically, the Press Type S impresses with its futuristic, reduced design.

• High pressure accuracy +/- 0.5 bar

• Very high temperature accuracy across the plate surface

• High-precision regulation of the temperature and pressure ramps

• Reduced energy consumption of the motor

• Can be used within a temperature range from 20 to 300°C, optionally up to 450°C

• User-friendly via touch-screen control

• Type SV presses are equipped with a vacuum chamber

• Test standard: standard practice for compression molding thermoplastic materials into test specimens, plaques, or sheets

• Including the extended cooling ramp up to 45°C

• Optional: Upgrade to fluoropolymer processing

COLLIN pressure filter tests can determine the difference in quality of a polymer caused by agglomerates, insufficientlydispersed fillers resp. impurities. For example, they can be used in the field of production development for optimising colour masterbatches, for quality control or output and input control of masterbatches, compounds or polymers. The pressure filter tests can also be combined with numerous extruders or compounders.

A filter cassette in pre-heating position allows for a quick, clean and manual filter change without extruder stop. During the filter change, the melt is deflected via a bypass valve in front of the filter.

• Easy and safe handling

• Improved reproducibility by double-chamber hopper

• Little idel times during screen change by cassette system

• Filter change without extruder stop

• Saving of working time due to optionally available double-chamber hopper

Applications:

• Product development – optimizing colour masterbatches

• Quality monitoring and control

• Incoming inspection and output control of masterbatches, compounds or polymers

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

Flat film lines with two rolls are particularly used for the production of films.

Flat film lines in the pilot sector are especially designed for the customer. Depending on the customer requirement, different designs of roll groups can be offered.

• Take-off speed standard up to 100 m/min, as option up to 200 m/min

• Roll position adjustable in x and z direction to one another

• Horizontal as chill roll (vertical die position)

• Diverse accessories, for example camera inspection etc.

• Upscaling to production lines
