Polymer mills with roll diameters of 110, 150 and 200 mm. We offer manual versions and fully automatic hands-free computerized mills used for color matching, quality control and research.
Laboratory Blown Film Lines:

12.5mm, 20mm, 25mm, 30mm, 45mm, all 30:1 L/D extruders.
Blown film lines for film lay-flat widths of up to 200 mm. Include features such as a twin-channel cooling ring, nip rolls, variable speed haul-off, slitters and winder.
   Co-extrusion lines for films with up to 9 layers. Large film tower with twin pillars, modern design enclosure, pneumatic nip rolls, infinitely variable-speed drive, high-capacity cooling ring, film wind-up, and freestanding central control cabinet incorporating all controls for the tower and extruders.

Hydraulic Laboratory Presses:
Hydraulic laboratory presses from 20 to 80 metric tons platen pressure. A double set of heating and cooling platens are standard. Available with a fully automatic platen insert cooling system as well as many platen configurations and control options.
Laboratory Filter Test:
Filter test with and without a gear pump for accurate quality testing and standardization of masterbatches and compounds. Standard filter sizes from 15 down to 5 microns.
Laboratory Single Screw Lab Extruders:
Single screw laboratory extruders with diameters of 12,5, 20, 25 and 30 mm, all with an L/D ratio of 30:1. The 20 mm extruder is available as a table top version. The 25 and 30 mm extruders are available both in vented or non-vented versions with plain screws or equipped with a Maddock mixing section, as well as a pineapple mixer at the screw tip.
Laboratory High Speed Lab Mixers:
25 and 75 liter pilot plant high-speed mixers with variable impeller speed, automatic mixing cycles and optional water-cooled impeller.
Laboratory Co-rotating Twin Screw Extruders:
Modular co-rotating twin screw extruders have clam-shell barrels and our unique super hard tool steel barrel inserts. Fully closed barrels are an option. Machines are available with 12, 16, 20 and 26 mm screw diameters and L/D ratios of 32:1 and 44:1

NEW! 12mm Twin Screw

  Laboratory Bench Top High Speed Mixers:

Bench top 10, 5 and 1.5 liter mini high-speed mixers with variable speed drive and easily removable mixing bowl.


Laboratory Chill Roll Film and Sheet Casting Lines:

12.5mm, 20mm, 25mm, 30mm, 45mm extruders, all 30:1 L/D.
Chill roll film and sheet casting lines are available both as floor and bench top versions. Flat die widths range from 125 mm for bench top versions up to 300 mm for floor versions. Dies have adjustable lips for sheet thickness from 0.3 to 1.5 mm or film thickness down to 0.01 mm. All three rolls are hard chromed, mirror polished and cored for water cooling and heating. Polishing roll is pneumatically operated.    Co-extrusion flat film and sheet lines for up to 5 layers. Suitable for producing film and sheet with materials such as PE, PP, PS, ABS, PVC, PET, PC, etc.
