Parts Heat Resistant
Description Of The Mold Sprue Bushing
The sprue bush is a part that allows plastic material to be
injected from the nozzle into the interior of the mold. It is fixed
to the mold with 2 bolts to prevent it from falling off due to the
injection pressure. In order to prevent leakage of plastic
material, the feed port is generally designed in an arc shape.
Quick Details Of The Mold Sprue Bushing

Materials Of The Mold Sprue Bushing
1. SKD61 hot work die steel can produce high-end and very durable
sprue bushing, the hardness can reach 48~52HRC. The sprue bush made
with SKD61 has the characteristics of high temperature resistance
and durability, and the quality of the molded product is excellent.
2. SUJ2 bearing steel is a commonly used manufacturing material for
the middle end sprue bushing. The heat treatment hardness is about
±HRC52.
3. S45C, the material used in the low-end mold, after the high
temperature, spray anti-rust oil and other anti-rust treatment to
prevent rust.
Size Of The Mold Sprue Bushing
The relationship between the size of the sprue sleeve and the
tonnage of the injection molding machine is as follows. the types
of plastics materials being injection molded have a littell impact
on them.
| Size of sprue sleeve | φ2.5 | φ3.0 | φ3.5 | φ4.0 | φ4.5 | φ5.0 |
| Tonnage of injection machine | 25~80T | 100~150T | 160~200T | 220~260T | 300~350T | 400~450T |
