Precision CNC Machined Cap Mold Components | High-Polish Injection Molded Parts

Product Overview

Polishing precision CNC machined parts are critical functional components used in cap injection mould tooling, where surface quality, dimensional accuracy, and mould stability directly affect part appearance and consistency. Senlan Precision manufactures customized mould components through CNC machining and controlled polishing processes to meet strict tolerance and surface finish requirements for multi-cavity cap moulds. All parts are produced strictly according to customer drawings (Built-to-Print).

Key Features & Advantages

• Precision CNC Machining
  High dimensional accuracy ensures stable assembly and repeatable performance in cap mould systems.

• Controlled Polishing Process
  Surface polishing is applied according to mould functional requirements, improving demoulding performance and surface quality of plastic caps.

• Stable Dimensional Control
  Tight tolerance management supports high-cavity mould applications with consistent part geometry.

• Material Flexibility
  Machined from customer-specified mould steels or engineering materials based on tooling design requirements.

• Built-to-Print Manufacturing
  Fully customized production according to customer drawings, specifications, and tolerance standards.

Application Scenarios / Industry Use

• Plastic bottle cap injection moulds

• Packaging closure mould components

• Multi-cavity cap mould tooling

• Cosmetic and daily packaging mould systems

• Precision plastic moulded part tooling

Mold Structure & Design Description

Polished CNC machined parts are typically used in forming areas of cap moulds where surface quality and dimensional accuracy directly influence part appearance and sealing performance. These components may function as inserts, cores, or forming surfaces within the mould structure. Controlled polishing levels are applied based on part geometry and mould design, ensuring functional surfaces without over-polishing that could affect tolerances.

Frequently Asked Questions (FAQ)

Q1: Can polishing level be customized based on mould requirements?
Yes. Polishing is applied according to drawing specifications or functional requirements, not as a standard cosmetic finish.

Q2: Do you only manufacture according to drawings?
Yes. All parts are produced strictly based on customer drawings and technical specifications.

Q3: Are these parts suitable for multi-cavity cap moulds?
Yes. We have experience supplying precision machined and polished components for high-cavity cap mould systems.

Q4: What tolerances can you achieve?
Tolerance capability depends on part geometry and material, and will be evaluated during drawing review.
