and the threaded components are made of W6Mo5CR4V2 wear-resistant alloy steel, with a
hardness of HRC60, with conveying blocks, mixing blocks, shearing blocks, banburying blocks,
kneading blocks, countercurrent blocks, building block series components, and the mandrel is
gradually splined and can be combined according to any material ratio to meet the needs of
different extrusion processes
7. Barrel material: The 5-section barrel is made of 45# nitriding steel forgings, lined with a301
wear-resistant alloy sleeve, with hardness of HRC60, and treated by nitriding, quenching and
tempering and ultra precision grinding, with surface roughness Ra ≤ 0.4μm. Wear and
corrosion resistance

the machine barrel is multi-section type, with self-cleaning function
9. Heating zone: 5 cast aluminum heaters fixed at barrel, 1 heater at handpiece, each section
with 1 kw heating power, external covered with safety protective wind hood
10.Cooling zone: The entire section of the barrel adopts a soft water circulation cooling system,
each segments of cooling water flow rate is adjustable, equipped with self-priming circulating
water pump, 304 stainless steel water storage tank, inlet and outlet water pipes and the
electromagnetic valve components,etc. Can implement independent temperature control and
cooling for each section of the barrel unit
11.Vacuum zone: Water circulation vacuum degassing device, equipped with water ring vacuum
pumps, vacuum gauge, regulating valve and other components, forming a non-clogging
dehumidification exhaust system
12.Feeding device: Adopting double screw metering type forced feeding, equipped with a horizontal
mixer, the feeding is uniform and stable, and it is not easy to bridge. The feeding speed is
adjustable by frequency conversion from 0-50rpm, and a sliding rail type fast discharge device is
installed
13.Reduction gearbox: High speed heavy duty hard tooth surface gear transmission, with an integrated
structure of gear reduction and torque distribution box, internal transmission parts adopt imported
high load bearing and oil seal, oil-immersed splash lubrication, smooth operation
14.Safeguard: Safeguard functions include: Melt pressure is interlocked with the host for overpressure
alarm protection; Melt temperature is interlocked with the host for startup and shutdown protection;
Feeding and host interlocking for startup sequence protection
