Precision Threaded Mold Cores | Custom Optical Cap Tooling Components

Product Overview

Custom made plastic mould parts with mold thread cores are precision functional components used in injection molds for optical thread cap applications. These thread cores are manufactured strictly according to customer drawings, focusing on dimensional accuracy, thread profile consistency, and surface integrity to ensure reliable demolding and stable performance in high-precision plastic cap molding systems.

Key Features & Advantages

• Built-to-print manufacturing based on customer-provided drawings

• High-precision thread geometry for optical and fine-pitch caps

• Stable dimensional control for repeated molding cycles

• Controlled surface finish to reduce friction and wear

• Suitable for multi-cavity and high-output injection molds

• Compatible with complex unscrewing or thread-release mechanisms

Applications / Industry Use

• Plastic bottle caps and closures with optical or fine threads

• Precision packaging molds for transparent or functional caps

• Medical and pharmaceutical container molding

• Injection molds requiring high thread accuracy and consistency

• Multi-cavity molds for mass production environments

Mold Structure & Design Description

Mold thread cores are critical components used to form internal or external threads in injection-molded caps. For optical thread cap applications, the core design must ensure accurate thread angles, pitch, and concentricity. Senlan Precision manufactures thread cores with optimized structural design to support smooth demolding, stable engagement with mold mechanisms, and consistent thread formation throughout the mold’s service life.
