High Hardness Open Twin Screw Barrel, Double Screw Extruder Barrel for Plastic Compounding
Our open twin screw barrel (double screw extruder barrel) is customized for co-rotating twin screw extruders, fully open barrel structure for easy cleaning, material switching and equipment maintenance. Adopt vacuum quenching + integral nitriding treatment, hardness up to HRC58-62, excellent wear & corrosion resistance. Applicable for masterbatch, plastic recycling, polymer modification, food extrusion and chemical compounding. Support all mainstream extruder models: ZSE, STS, TEX, BCT series. Custom inner hole diameter, length, screw matching sizes available.
Open twin screw barrel, also called open double screw extruder barrel, is the core wear-resistant part of twin screw extrusion equipment. Different from closed integral barrels, split open design allows quick disassembly without removing the whole screw assembly. Operators can directly observe internal material melting status, clean residual plastic, replace kneading blocks or screw elements in minutes, greatly reducing production downtime for frequent formula switching factories.
Our high hardness extruder screw barrel is manufactured with high-quality alloy steel base material. We adopt precision CNC machining, inner hole mirror polishing and deep nitriding heat treatment, to guarantee long service life under high temperature, high torque and abrasive material processing conditions.
-
Open Split StructureFully open barrel body, top cover removable. No need to pull out twin screws when cleaning, suitable for multi-color masterbatch, lab extrusion, frequent formula replacement production lines.
-
Ultra High Hardness Wear ResistanceDeep nitriding layer, surface hardness HRC 58–62. Resist abrasion from calcium carbonate, talc, glass fiber, carbon black filler materials. Anti-corrosion when processing acid & alkaline polymer materials.
-
Precision Machining & Stable Dimension5-axis CNC finish machining, twin 8-shaped inner hole with low tolerance, perfect fit with twin screw shafts, no material leakage, stable extrusion pressure. Inner wall mirror polishing to avoid material adhesion and dead angle carbonization.
-
Customized Size & Model MatchingCustom barrel length, opening position, heating/cooling hole layout, mounting flange hole position. Compatible with ZSE, STS, TEX, BCT, ZE series twin screw extruders, support lab small open barrels and large industrial production open barrels.
-
Long Service CycleIntegral alloy steel forging base, anti-deformation under 300℃+ long-term working temperature. Uniform nitriding layer without peeling, reduce spare parts replacement cost for extrusion factories.

Q1: What is open twin screw barrel?
A: Open twin screw barrel is split type double screw extruder barrel with removable top cover, easy to open and clean internal screw components, widely used for frequent formula switching extrusion lines.
Q2: Why choose high hardness extruder screw barrel?
A: High hardness nitrided barrel has strong wear resistance, not easy to scratch when processing filled plastic with glass fiber, calcium powder, extend service life and reduce production cost.
Q3: Can you customize open double screw barrel for our extruder model?
A: Yes, we support fully customized size for all twin screw extruder brands and models, just provide your extruder drawing or screw diameter parameter.
Q4: What’s the hardness of your twin screw barrel?
A: Our standard open twin screw barrel reaches HRC58-62 after deep nitriding treatment, much higher than ordinary barrels on market.
