Performance andspecification
1)We design our brand, screw andbarrel .We make sure the course of processing smoothly.
2)With almost 10 years''experience in plastic machinery, we have a well quality controlsystem.Screws are processed by high-precision special NC screwmilling machines to ensure high consistency extruding performance.We try our best to lower the cost of your budget and supply highquality screw and barrel .The special design of distribution cainetenlarges thrust bearing and adopts original bearings, guaranteeingthe long service life and the bearing of larger extrusioncapacity.
3)With suitable moulds, our screwand barrel can make high quality soft PVCpipes, hard PVC pipes ,profiles, sheets, master batch and so on.
4)According to customerrequirements , most reasonable screws and barrrels can beconfigured to achieve optimal plasticization and logisticquality.
5)Process :Laser coating TungstenCarbide, PTA melt-welding alloy, centrifugal mould bimetallic alloy, advanced nitrogen oozes handicraft , vacuumquenching , Titanizing, Nickel plating and ChormePlating.
