Z51 HASCO Sprue Bushing Injection Mold Components Nozzle Tips
A sprue bushing made of hot working die steel SKD61 features the
properties of heat/wear resistance.
To prevent leakage of plastic materials, the feed throat is usually
designed into a chamfer R. The SR (spherical radius) of the mold
sprue should be 1 – 2mm larger than the sr of the injection nozzle.
Please refer to injection machine specs for the sr of the injection
nozzle.
