The performance for the *5 parallel twin screw barrel are as following:

***Material

1)*8CrMoALA(JIS SACM**5)

2)*2CrMo(JIS SCM**0)

3)9Cr*8MoV
4)CW6Mo5Cr4V2

5)Various high quality alloy steels,According to different usage, the choose for alloy is different, some require for abrasion-resistant while some require for corrsion-resistant. For standard, we have Fe-based, Ni-based, W2C alloy,Tunsten alloy etc for choice.

***Application:

various high glass fiber, mineral fiber and PPA,PPS, PA6T, LCP,VO fire protection, ferrous power, magnetic powder and etc. Meanwhile,Used for PVC + *0% CaCo3, recylced plastic material
