±0.01mm Parallelism Mold Inserts | Precision Parts for Cosmetic Packaging Molds

Product Overview

Senlan Precision manufactures high-precision mold core inserts for cosmetic packaging plastic injection moulds. These components are produced under strict machining control to achieve parallelism within 0.01 mm, ensuring stable cavity alignment and consistent molding quality. All parts are custom-built to print, suitable for high-cavity and precision cosmetic packaging mould systems.

Key Features & Technical Advantages

• High Parallelism Accuracy
  Mold core inserts are controlled to ≤ 0.01 mm parallelism, ensuring uniform cavity geometry and reliable part consistency across multi-cavity moulds.

• Precision CNC Machining
  Manufactured using advanced CNC milling and grinding processes to maintain dimensional stability and repeatability.

• Material Options for Cosmetic Moulding
  Available in selected tool steels and stainless steels suitable for cosmetic packaging mould environments, balancing wear resistance and surface quality.

• Stable Performance in Multi-Cavity Moulds
  Designed for high-cavity cosmetic packaging moulds where alignment accuracy directly affects product appearance and assembly performance.

• Built-to-Print Manufacturing
  Fully customized according to customer drawings, tolerance requirements, and mould structure specifications.

Applications / Industry Use

• Cosmetic Packaging Moulds
  Mold core inserts for lipstick tubes, cosmetic caps, closures, and small packaging components requiring tight dimensional control.

• Plastic Injection Moulding Systems
  Suitable for precision injection moulds where cavity balance and parallelism are critical to molding quality.

• High-Cavity Production Moulds
  Widely used in moulds with multiple cavities where cumulative tolerance control is essential.

Mould Structure & Design Description

• Core Insert Function
  The mold core insert forms critical internal and external features of cosmetic packaging components, directly influencing surface finish and dimensional accuracy.

• Parallelism Control
  Parallelism within 0.01 mm ensures correct cavity alignment, reducing flash, uneven wall thickness, and part deformation during injection.

• Interface & Fit Design
  Inserts are manufactured with controlled fit tolerances to ensure stable installation and repeatable positioning inside the mould base.

Manufacturing Capability & CNC Machining

• CNC Milling & Precision Grinding
  High-precision machining processes ensure accurate geometry, tight tolerances, and consistent batch quality.

• EDM Support for Complex Geometry
  EDM machining is available for sharp corners, deep features, or complex cavity shapes when required by design.

• Small to Medium Batch Flexibility
  Capable of prototype, pilot, and production-level quantities for cosmetic packaging mould projects.
