D-2 Tool Steel Flanged Core Insert
Flanged Core Inserts are precision-engineered from premium D-2 tool steel to deliver excellent hardness, wear resistance, and dimensional stability. This component features a cylindrical core body, central through hole, top profile relief slots, and a flanged mounting base with positioning holes. It is designed to ensure accurate mold assembly, stable core positioning, and reliable performance in high-precision injection molding applications.
They are widely used in bottle cap molds, cosmetic packaging molds, medical device molds, plastic closure molds, automotive plastic molds, and other precision injection molding applications requiring accurate internal forming, stable alignment, and long service life.
- Material: D-2 Tool Steel
- Hardness: HRC 58–62
- Tolerance: ±0.01 mm
- Surface Finish: Polished / Ground
High-Precision Engineering
Our flanged core inserts are manufactured using precision CNC turning and grinding equipment to ensure accurate outer diameter, inner hole size, roundness, and perpendicularity. The cylindrical core body and flange base are carefully controlled to maintain stable positioning inside the mold.
This allows the insert to fit securely within the mold structure, helping reduce assembly deviation and ensuring consistent molded part quality during repeated production cycles.
