Specifications

Characteristics of double-alloy tube

Double metal barrel that is 45#, 40Cr, 42CrMo other common alloy steel casting in shallow holes in the surface layer of high abrasion resistance, high resistance to corrosion of the alloy layer,life is longer than doubled nitride hardened cylinder for processing without Halogen-free high-temperature plastic, engineering plastics, plastic dual-metal fluoride superiority of utmost prominence.

SLF Characteristics of bi-metallic tube

SLF double metal tube base with 45#, 40Cr,the inner layer of iron-based alloy used(more than 64% Fe) alloy powder, made by centrifugal casting high temperature,hardness(HRC)60-64,Applicable to the general corrosion plastic raw materials.

SLN bi-metallic inner tube alloy, nickel-based alloy powder used, through sophisticated

high-temperature casting, the alloy layer and substrate toachieve a tight fusion of the alloy layer

with excellent wear and corrosion performance, but also possesses excellent resistance to heat

characteristics. Products favored by domestic and foreign customer praise. Especially in the use

of halogen-free plastic area leader.

SLP FEATURES ALL ALLOY COATED SCREW

SLP all alloy coated screw is a two-edge research and development of the latest machine screw,

the matrix used SKD61,SKD11,42CMO high strength steels, the surface alloy layer of nickel-based

alloy layer, through a special bonding process. So that with the base alloy layer precise

combination of melting into one.

By adjusting the alloy layer composition, for a variety of high corrosion, wear and tear and strong

raw material of lastic injection, extrusion.

SLP full alloy coated screw commitment, under normal use,the halogen-free plastic for more than

10 months warranty, Bakelite plastics for more than 18 months warranty.
