H13 (SKD61) Helical Threaded Cores | Precision Inserts for Cosmetic Molds

Product Overview

The SKD61 hardened die steel rifling with screw is a precision-manufactured mold component designed for cosmetic plastic injection molds requiring controlled demolding and high surface durability. Manufactured under strict dimensional control, this rifling insert is engineered to ensure stable performance, wear resistance, and reliable positioning in high-cycle cosmetic packaging molds.

Key Features & Technical Advantages

• Manufactured from hardened SKD61 hot work die steel

• Integrated screw structure for secure positioning and assembly

• High wear resistance suitable for long production cycles

• Precision rifling geometry for controlled demolding behavior

• Stable dimensional accuracy under thermal and mechanical load

• Fully customized according to drawings (Built-to-Print / OEM)

Applications & Industry Use

• Cosmetic packaging injection molds

• Bottle, cap, and closure molds with internal structure control

• Plastic molds requiring rifling or guided demolding features

• Precision molds for daily packaging components

Mold Structure & Design Description

This rifling component is designed as a functional mold insert with an integrated screw structure, allowing precise axial positioning within the mold assembly. The rifled surface geometry supports controlled plastic flow or demolding behavior, while the hardened SKD61 material ensures stability under repeated injection cycles. All dimensions, tolerances, and interfaces are manufactured strictly according to customer-approved technical drawings.
