Beryllium Copper (BeCu) Injection Mold Pins and Sleeves | High-Polish Finish

Product Overview

Be-Cu injection molding pins and sleeves are high-performance mold components designed for applications requiring efficient heat dissipation and stable dimensional performance. Senlan Precision manufactures beryllium copper pins and sleeves with polished surface treatment to ensure smooth mold operation and consistent molding results. All components are produced under a strict Built-to-Print model, following customer drawings and technical specifications.

Key Features & Advantages

• Excellent Thermal Conductivity
  Beryllium copper material supports rapid heat transfer, improving cooling efficiency in injection mould systems.

• Polished Surface Treatment
  Controlled polishing reduces friction during mold operation and supports stable part release performance.

• High Dimensional Stability
  Precision machining ensures consistent fit between pins, sleeves, and surrounding mold structures.

• Material Selection for Mold Performance
  Be-Cu alloy is selected based on functional requirements such as cooling efficiency and mold cycle stability.

• Built-to-Print Custom Manufacturing
  All parts are manufactured strictly according to customer drawings, tolerances, and surface specifications.

Application Scenarios / Industry Use

• Injection mould pins and sleeves for packaging moulds

• Bottle cap and closure mould systems

• Medical plastic component mould tooling

• High-cavity injection moulds requiring enhanced cooling

• Precision mould assemblies with thermal control requirements

Mold Structure & Design Description

Be-Cu pins and sleeves are typically installed in core or ejector-related areas of injection moulds where thermal management is critical. These components help reduce localized heat accumulation and improve cycle consistency. Machining accuracy, concentricity, and surface finish are controlled to ensure stable integration with steel mold components and reliable long-term operation.
