双金属机筒就是在机筒内壁浇铸一层2一3 mm的耐磨耐腐蚀的、耐高温的合金,其有效使用寿命比普通氮化机筒大大提高,对于加工工程塑料、氟塑料、聚砜、PPO殊类型的塑料等,双金属的优越性尤为明显。
本公司生产的双金属螺杆,采用特殊合金粉末在螺杆螺棱部分喷焊合金,可以针对不同功用的螺杆,
采用不同的合金和焊合方式。


Bimetal barrel is on the inner wall of the barrel, cast a layer of 2-3 m m wear-resieting corrcslon raslstanca.hah temperature resistant alloy,its affecttve mechanism for service life than ordnary nitrogen oylinder is greatly increased,for processing and engineening pastic,fuorine pastics,polysulfone.PPO different types of pastic,etc.especally the advantages of doubko metal,
Thie ccmpanry produces the bimetallic screw, the use of special aloy powder in the screw screw edge part of the spray welding alloy. can according to different functicns of the screw,
Using dfferent ways of alloy ard welded.
