Bimetallic screw barrel in high quality

   For bimetallic screw ,we have adopted advanced technique(HP/HVOF)of surface harden Process by the whole screw surface,WPT1 alloy with corrosion resistant suits for nylon,PVC,PC,PMMA and so on.WPT2alloy corrosion resistant and high temperature resistant Suits for magnetic power ,maanetic powder,magnesium and alumimum powder.Bakelite injection and so on .WPT3 is compatible with WPT1 and WTPT2.
   For bimetallic barrel ,we have raised the proportion of tungsten contained in alloy to 30%and 50%from previous10%,and we also have increasedthe processing length to 4000mm from the previous length of 3000mm.

Technical Parameters 
Bimetallic Screw Barrel in High Quality

The main advantage of  screw barrel:

 a. Advanced Nitriding Technology 
 b. Anti-corrosion and Wear-resisting Duplex Metal Spraying Technoloy
 c. we uses special alloy powders being sprayed and welded on the screw's ridge,and uses different alloy and welding methods for the screw of different functions.

Ruian yumin machine screw co.,ltd is a factory specialized in making
 screw barrel in various materails, filter, t die, gearbox, and extruder machine
. We are largest one in Ruian city who supply main parts to machine- maker with the history over 24 years. Our workshops cover lands over
 5.000 cube meters. We have two factories in Ruian, with 4workshops. 
We have many computer-control CNC milling machines with the length 8000mm in Fanuk series,
 18000mm length deep hole drilling machine, and other advanced equipments.
 All the process is done by ourself, including nitrding treatment. 
We do nitriding treatment for 7 days and nights, 
which ensure the hardness and lifetime of screw barrel a lot
. Meanwhile, our factory and products are passed the assessment by SGS company, 
and Bureau of Veritas, TUV, and CE certificate.
