DLC Coated Core Inserts | Precision Tooling for Flip-Top Bottle Caps

Product Overview

Surface coated round core inserts are precision mold components designed for flipable bottle cap injection tooling where wear resistance, surface stability, and dimensional consistency are critical. Through controlled CNC machining and functional surface coatings, these inserts support stable molding cycles, reduced friction during demolding, and extended service life in high-volume multi-cavity injection molds.

Key Features & Technical Advantages

• Precision round core insert for injection molding applications

• Functional surface coating for improved wear and friction control

• Stable dimensional accuracy under repeated molding cycles

• Optimized geometry for flip-top and hinged cap mold structures

• Suitable for multi-cavity and high-output tooling

• Fully customized, built-to-print manufacturing based on drawings

Applications & Industry Use

• Flipable / flip-top bottle cap injection molds

• Multi-cavity molds for packaging closures

• Precision plastic molds requiring smooth demolding

• Packaging and medical plastic component tooling

Mold Structure & Design Description

In flipable bottle cap molds, round core inserts play a critical role in forming internal geometry and supporting hinge or snap-fit structures. Surface coatings are applied to reduce adhesion between plastic material and core surfaces, helping to improve demolding stability and reduce wear. Insert dimensions, coating type, and tolerances are defined according to mold design and production requirements.
