Twin Screw Extruders
KTE-50 to KTE-95B lines running masterbatch, PET / rPET recycling, LFT long fibre and elastomer pelletizing — full-line shots, cutter close-ups and startup runs.

Extruder running videos: watch the line before you pay for it
Extruder running videos answer a question a datasheet cannot: does the pellet come out uniform, and does the cutter keep up. Footage here is filmed in customer plants and on our own trial line, sorted by machine family.
YouTube playlists: watch the lines by machine family
Eleven playlists cover every machine family on the channel. Each cover below plays the whole playlist on this page with one click — no autoplay, nothing leaves the page. New clips join their matching playlist the day they publish, so the counts climb as the library fills.
Single Screw Extruders
One screw does the feed, the melt and the pump: smooth-bore lines pelletizing clean, free-flowing materials at the lowest cost per kilo.
Plastic Recycling & Pelletizing
PP / PE film and rigid scrap washed, dried and repelletized — two-stage degassing, screen-changer behaviour and pellet quality after the regrind.
Masterbatch Compounding
Pigment and filler concentrates at high loading: side feeding, dispersion, and the colour check straight off the die face.
Two-Stage Extrusion Lines
A twin screw compounds, a single screw pelletizes — the split that keeps heat- and shear-sensitive fills from degrading on the way to the cutter.
Kneader Pelletizing Lines
Kneader plus single screw for materials too viscous or too heavily filled for a twin screw to push — high-filler masterbatch and specialty compounds.
Lab & Pilot Extruders
Bench-scale twin screws for formulation trials: 25–50 kg on the lab line before a buyer commits to a production configuration.
Company Videos
Short films on the machine range — twin, double and triple screw — and how a line is configured around the buyer’s material rather than a catalogue.
Biodegradable & Degradable Compounds
PLA, starch (TPS) and compostable blends on air-cooling strand pelletizing — moisture- and heat-sensitive materials run without water contact so the chain does not hydrolyse.
Plastic Modification & Compounding
Filling, reinforcing and toughening cases — calcium carbonate, glass fibre and elastomer modification with the before / after pellet shot.
Kerke Extrusion Factory Tour
Walk the assembly floor: screw barrels, tooling benches and the test rig every line runs on before it ships to a customer.
Still filling: a Food Extrusion Lines playlist starts collecting clips with the next upload batch, and every list above gains videos the day they publish.
Quick answer
The extruder running videos library collects customer plant footage, trial runs and pelletizing close-ups across 11 playlists, one per machine family. Videos are hosted on our YouTube channel and published once the customer approves the clip; each playlist above plays on this page with a click-to-load player, so nothing autoplays on mobile networks.

What the extruder running videos library holds
- Line running: extruder, die, cutter and pellet flow in one continuous shot — the clip that shows surge if there is any.
- Pellet close-ups: shape, dust, uniformity, and the difference between water-ring and underwater cut on the same material.
- Trial runs: materials we have not delivered yet, filmed on the lab line so a buyer can see behaviour before committing to a configuration.
- Startup: heat-up sequence, torque ramp and first pellets, which is where most operators ask for help.
Footage is grouped the same way as the rest of the site: by machine family first, then by material. The matching parameter pages are under lines by application, and the projects behind them under case studies.
How to request footage
- Send the material, the target output and the pellet standard you sell against.
- We name the closest configuration already delivered and check whether footage exists.
- You receive the playlist and clips that match — plant footage, pellet close-up, and the trial run if the material is new to us.
- If nothing close exists, the answer is a trial: 25–50 kg on the lab line, 3–7 days.
Requests go through the quotation form or the WhatsApp button; both reach the same team. The trial process is described on service.
What to look for when you watch
Ignore the machine and watch three things. The strand or the die face: does the melt come out evenly across the whole face, or is one side starving? The cutter: does the pellet count stay constant, or does the ammeter swing? The pellet bin: are the pellets uniform, or is there a tail of fines that will block a feeder downstream? A line that looks calm in all three places is usually a line that was commissioned properly.

FAQ
Can I get the original video file or a longer cut?
The public library lives on the Kerke YouTube channel; request a longer or specific clip via kerkepm@gmail.com and we share the relevant segment.
Are these videos from real customer plants?
Both - customer lines where permission allows, and our own test floor with the customer's material running.
Can you run my material on camera?
Yes - that is exactly what a material trial delivers: 25-50 kg in, pellets, running video and a measured output report in 3-7 days.
