Barrel series
Introduction:
Jinhailuo is the best screw brand since 1978 . Nearly 40 years of experience and history in the manufacture of screw and barrel .
We have more than 10 groups furnace that depth can up to 12.5m , and a number of advanced screw and barrel professional processing equipment to meet the larger scale equipment's high quality demand . We have processed the diameter of the screw and barrel can be reached 350mm.
Jwell will continue to keep innovation and improvement . Using high quality alloy steel as the base material, controlling the whole process of the quenching and tempering , qualitative , nitriding , surface alloy process .

Conical twin screw
This series screw designed for mainly PVC products , conical twin screw rotate in lower speed , the material inside the barrel under a stable and uniform shear , shorter screw , shorter duration time of material , especially suitable for heat-sensitive material plasticizing process .
The main applications :
Including PVC pipe , PP/PVC/PE WPC extrusion , PVC skinning foaming plate , PVC profile , PVC/PP corrugated pipe , PVC floor leather products , PVC waterproof membrane .
The main technical data :
Material : 38 CrMoAlA ( JIS SACM645) 9 Cr18MoV
Heat treatment : Nitriding treatment , spraying coating Bimetallic alloy Depth of nitration layer : 0.5~0.8mm
