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.
