  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.
 a. Advanced Nitriding TechnologyÂ
 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.

High Quality Conical Double Screw Barrel 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.Â
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.Â
We do nitriding treatment for 7 days and nights,Â
which ensure the hardness and lifetime of screw barrel a lot
. Meanwhile, our factory and products are passed the assessment by SGS company,Â
and Bureau of Veritas, TUV, and CE certificate.Â

Fructooligosaccharides (FOS) also sometimes called oligofructose oroligofructan, are oligosaccharide fructans, used as an alternativesweetener. FOS exhibits sweetness levels between 30 and 50 percent ofsugar in commercially prepared syrups. It occurs naturally, and itscommercial use emerged in the 1980s in response to consumer demandfor healthier and calorie-reduced foods.
