This is where plastic is fed through an extruder to produce a range of products including plastic film, planks, pipes, profiles, and strapping tape, to name a few, from materials like LDPE, HDPE, LLDPE, PP & PA (nylon). Using principles like Co extrusion (where a number of layers of plastic are used for strength or cosmetic purposes) and die rotation (where the die head rotates increasing quality and uniformity)

Kween B manufactures and sell a whole range of extruders from small minilab series for research and development or specialist requirements, through to the largest of extruders for mass production in the most commercial of environments. Kween B offers over 100 different new options that can be custom built for individual requirements or geared up for multi machine requirements. A range of refurbished second user models are also available for those on a tighter budget. Kween B can install and commission all machines supplied

EXTRUDERS

Single Screw for all purposes from a minilab environment up to 6 metre barrel lengths

Twin screw with Co Rotation for compounding type applications

Twin Screw with Contra rotation for applications like PVC.

EXTRUSION LINES

Blown Film –For the production of things like plastic bags, pool liners & damp proof course to name but a few made out LDPE, HDPE, LLDPE, PP, & PA (nylon)

Co extrusion Blown Film- For cosmetic, security or strength applications.

Pipe, Profile and Hoses Lines (With reinforcement if necessary)-For window profiles, garden hose and drainage pipes requirements

PP Strapping Tape-For packaging

Weaving Tape Lines-For the manufacturing of woven sheet (eg Tent material or Sacks) with or without liners

COMPOUNDING LINES

Single Screw Extrusion

Twin Screw Extrusion

Compounding is used when you wish to add a colour to the plastic, adding fillers to a plastic (to make the plastic have a special finish eg matt or to reduce the amount of plastic used in a job eg weight or cost), alloying plastics (adding metallised finishes), filtering and homogenising (making the material similar throughout eg mission critical production)

MASTERBATCH LINES

These are for the manufacture of masterbatch, whether this be the need for Intensive mixing for colouring, the adding of molten wax to the material for lubrication or the pre-dispersion of material for pellitisation which will later be added to raw plastic for extrusion

DOWNSTREAM

Kween B manufactures a full range of downstream equipment once the product has been extruded including

Calibration baths with vacuum pumps

Caterpillar Haul-offs

Cut off saws

Coilers

Stackers

FILTERS

Used to protect the final product from alien objects and impurities. Kween B offer both manual and automatic types. These include

Lantern slide screen changer with hydraulic power packs

Twin Cylinder non-stop extrusion filters with hydraulics

Manual lever spectacle type

PELLETISERS

These create small pellets from extruded plastic (which are used for colouring or mixing or filling with other materials). Kween B offer a range of pelletisers to fit all preferences and materials.

- Multi blade strand pelletiser

- Dry die face pelletisers with cooler takeoffs

- Water-ring hot die face pelletisers with dryers and takeoffs
