Barrel&screw material:W6Mo5Cr4V2 high speed tool steel
L/D:36:1
Length of barrel:360*9 section=3240mm
Special screw array with wear shear of flake material, super power vacuum system to reduce IV loss maximumly.
Barrel
1). Structure: The first section works for main feeding, the second section is for natural vent, and the fifth and the seventh section is set up for vacuum venting, the others are blocked.
2). Material: The material of the barrel is made of 45＃forged steel with the linear material Cr26 inside that smooth and abrasion resistant ( Integral linear section, a complete “∞”). The hardness is HRC60-64.
3). Heating: Adopt multiple step format electric heating. The first and the second zone and the machine head zone are cast copper heater and others are cast aluminum heater. The total heating power is 120kw and the max heating capacity every section can reach
500℃.
4). Cooling: Adopt soft water cooling system in the barrel and tap water cooling way outside barrel. The circulation pipes are made of stainless steel and the water inflow regulating valves are stainless valves.
The brand of electromagnetic valve is DANFOSS.
5). Length: 520*9=4680mm
