3D PRINTING FILAMENT EXTRUSION LINE/PLC TYPE

一、Double- Screw Extruder

1、Screw diameter：Φ20

2、Length diameter ratio：1:40 Optional

3、Screw direction：Parallel and same direction

4、Screw：Spindle with 40 CrNiMoAlA chromium molybdenum alloy tool steel,  screw thread adopts W6Mo5CR4V2 wear-resisting alloy steel,  hardness is HRC60,with transportation, mixing, shearing, mixer,  kneading and reflux block, building block series components, can combine according to any material recipe, to meet the needs of different extrusion process.

5、Barrel：5 sections of cylinder adopt 38 CrMoAlA nitriding steel forgings,  liner wear-resistant alloy, hardness is HRC60, via nitriding,  conditioning and ultra fine grinding process,  the surface roughness Ra≤0.4μm,  wear-resisting and corrosion resistance.

6、Heating zone：5 cast aluminum heaters fixed at  barrel,1 heater at handpiece,  each section with 1 kw heating power, covered with safety windshield outside.

7、Cooling zone：Cylinder segment using soft water circulation cooling system,each segments of cooling water flow rate is adjustable,  equipped with self-priming pump, 304 stainless steel water storage tank , water pipe and the electromagnetic valve component,etc.Can apply independent temperature control at each segments of cylinder.

8、Feeding device：Adopt screw feeding and vibration feeding methods. Feeding  speed from 0 to 50 RPM is frequency adjustable. The connection method between feeding device and host is sliding mode, it’s convenient to clean up the screw. Feeding stably, difficult to bridge.

9、Reduction gearbox：High speed heavy hard teeth surface gear transmission,  gear reduction and torque distribution box is integration structure, internal transmission parts adopt imported bearing and oil seal,  oil splash lubrication.
