Why should the hot runner valve pin be plated with titanium?
Why should the hot runner valve pin be plated with titanium?
1. Improve surface hardness, increase wear resistance,
decoration and corrosion resistance to make production more usable and increase
service life.
2. PVD coating benefits
1) Extremely high hardness →Wear resistant →Extended life (generally 3 to 10 times)
2) Small coefficient of friction →Smooth, low frictional
resistance →Low wear →Extended
life
3) Not easy to interact with metal →Anti-adhesive, anti-addition →Improve strain and pull →Improve the surface quality of processed products
