★ DAC metal again by the depth of tempering after quenching vacuum AFA direct sales, good toughness, torque to maximize the promotion, and then chrome plated nanoscale titanium enhance its surface hardness, reduce the surface friction coefficient (wear); upgrade its surface smooth, finish AFA price, then molecular distribution is more uniform, more compact and contains corrosion resistance of chromium and titanium (corrosion resistance). Halogen-free plastic material which particularly corrosive at high temperatures will produce a strong acid gases, corrosion of metal with a strong, plus glass will increase wear and increase its corrosion area so that the AFA sales increased corrosion of the screw feeding tubes are causing great corrosion. This series of halogen-free special screw feeding tube set for a variety of halogen-free plastic plus 20-40% glass fibers, mineral fibers, and PPA, PPS, LCP, magnetic, PEI, bakelite powder and other special engineering plastics.
