50mm Twin Screw Extruder Barrel, 0.05mm Dimensional Tolerance WR13 SAM26 Alloy OEM Custom Barrel

Our 50mm twin screw extruder barrel hits 0.05mm ultra-tight machining tolerance. We forge each barrel with WR13 or SAM26 wear-resistant alloy. This twin screw extrusion barrel matches all co-rotating twin screw extruders across food, chemical, plastic and pharmaceutical production. Every 50mm extruder barrel passes ISO9001 full quality inspection before shipment.

If you source matching mixing accessories, jump to our twin screw kneading block & screw element series for full extrusion line spare parts.

We lock all cavity and flange dimensions within 0.05mm tolerance. The 8-shaped twin inner bore fits screw shafts without gaps. No material leakage, no unstable flow during long continuous extrusion runs.

For ultra-high precision compounding, check our 0.02mm ultra-precision twin screw barrel series for stricter tolerance options.

We use WR13 and SAM26 alloy as standard raw material for the 50mm twin screw extruder barrel. The alloy withstands abrasion from filled plastic, food powder and chemical additives. It cuts your barrel replacement frequency effectively.

If your production involves corrosive raw materials, view our anti-corrosion alloy twin screw barrel range for alternative material solutions.

We build twin screw extrusion barrels from 16mm up to 350mm center diameter. The 50mm model is our hot-selling standard size. Our engineers adjust barrel length, cooling channels and mounting hole layout fully based on your equipment drawings or samples.

We accept OEM orders for new twin screw extrusion machine assembly and worn barrel replacement. Our technical team reverses your samples or optimizes your CAD drawings for better extrusion performance. We also provide matching component layout suggestions.

If you maintain old extrusion equipment, explore our replacement twin screw barrel kits for matched full sets.

The 50mm twin screw extruder barrel runs stably across four major industries: food processing, plastic compounding, chemical mixing and pharmaceutical production. It maintains consistent output for pasta, snack food, plastic masterbatch, resin, adhesive and pharmaceutical granule manufacturing.

If you focus on food-grade extrusion, take a look at our food-grade twin screw barrel collection.

1. Food Industry: Process pasta, breakfast cereals, puffed snack raw materials
2. Plastic Industry: Modify plastic, produce color masterbatch, recycle waste plastic granulation
3. Chemical Industry: Mix resin, adhesive, filling chemical compound materials
4. Pharmaceutical Industry: Mix medical powder, prepare pharmaceutical extrusion granules

We coat anti-rust protective oil on every 50mm twin screw extruder barrel surface. We wrap barrels with shockproof foam and seal inside solid export wooden cases. Our lead time spans 5 to 60 days, adjusted by your order quantity. We guarantee on-time delivery and intact product condition.
