Extruders
Mini-compounder, DSM Micro 15
DSM micro-extruder (DSM Research B.V., The Nederland) has 15ml volume capacity, co-rotating twin screw and the temperatures in the six heating zones range from room temperature to 400oC. The extruder can be fit with fibre and tape dies for the direct extrusion of fibres and tapes. The machine has computer telemetry giving data indicative of the viscosity, speed (rpm) and force (N).
Features
- Co-rotating twin screw (conical)
- 15 ml capacity
- Maximum temperature:400°C
- 6 different heating zones
- Different dies available
- Speed (rpm) and force (N) controlled
- Inert gas
- Water and pressure air cooled
- Online data recording (T, rpm, force)
- Direct inject moulding possible
Single Screw Extruder, Collin TEACH-LINE® E20T
The Extruder E 20 T of the TEACH-LINE® series are particularly aimed at the field of training and education. In combination with a wide range of modular downstream equipment, plastics processing techniques can be studied on a small scale.
Heating is provided by three barrel heating zones, two of which have air cooling and the inlet zone is water cooled. An easily removable hopper simplifies material changeovers and cleaning. Dies are connected using a quick release C-flange which simplifies mounting and de-mounting.
Features
- Screw speed: 5 – 200 rpm
- Max. throughput (LDPE): 2.5 kg/h
- A wide range of dies and downstream units are available
Twin Screw Extruder, Collin ZK25
The Collin twin-screw kneader is used in development and production of all types of polymer materials, such as thermoplastics, thermosets, elastomers, paints, foodstuffs, doughs and pastes. The control is arranged ergonomically in an operator panel positioned above the extruder. The controller serves for 15 temperature regulation zones, screw speed control, ampere meter or torque measurement, melt temperature and pressure measurement.
Features
- Applications with counter-rotating operation
- Applications with co-rotating operation
- Use as single-screw extruder
- Construction of the barrel from individual segments
- Construction of the screw from modular elements
- Easy cleaning by moving the barrel elements on a sliding rail
A number of processing tasks can be carried out, such as:
- Mixing and dispersion of pigments
- Incorporation of fillers and other additives in polymers
- Incorporation of fibre strands
- Alloying of polymers or pastes
- Degassing of volatile constituents from polymers
- Implementing continuous reactions

Injection Moulding
The micro injection moulding machine, BabyPlast CRONOPLAST S.L
Babyplast 6/10P is one of the smallest, fully hydraulic, injection moulding machines. Thanks to the unique concept of the machine platens which act as mould bolsters, the cost and dimensions of the moulds are reduced considerably. Babyplast 6/10P occupies less than 0,6m2 of floor space and is extremely quiet (< 68dB). This system is ideal for the production of micro parts suitable for all types of thermoplastic materials up to 420°C, metals and ceramic.
Applications
- Production of small precision parts
- Long and short production runs
- Laboratory tests / sample production
- Prototyping
- Medical products / clean room applications
- Technical training
Film Blowing
Film blowing unit BL 50L
- Laboratory machines for the processing of polymers with co-extrusion die
The BL 50 T blown-film tower is primarily used in teaching and research, and for demonstrating and testing the properties of polymers and polymer compounds which include:
- Optical appearance
- Haze
- Stretchability
- Maximum blow-up ratio
- Homogenisation performance of the extruder
- Gels, agglomerates and contaminants
- Dispersion of pigments and other additives
This system is also suitable to produce multi-layer composites and thin films used by the food industry or the medical field and plastic bags.
Features
- Nip roll diameter: 50 mm
- Nip roll width: 200mm
- Max. lay flat width: 170 mm
- Max. bubble diameter: 110 mm
- Take-off speed: 1 – 12 m/min
