AISI 304 Precision CNC Machined Slender Shafts | High-Precision Turning Parts

Product Overview

Senlan Precision manufactures SS304 precision CNC machined slender shaft components using CNC turning and polishing processes. These parts are produced strictly to customer drawings for injection mould assemblies and industrial tooling systems where straightness, surface finish, and dimensional stability are critical to functional performance.

Key Features & Advantages

• SS304 Stainless Steel Material
  Offers stable corrosion resistance, good machinability, and structural reliability for mould and industrial applications.

• Slender Shaft Precision Turning
  Optimized CNC turning strategies are applied to control straightness, concentricity, and diameter consistency along long shaft geometries.

• Polished Surface Treatment
  Fine polishing reduces surface roughness, improves sliding performance, and supports stable assembly within mould components.

• High Dimensional Consistency
  Critical tolerances are maintained to ensure reliable performance in precision mould and tooling systems.

• Built-to-Print / OEM Manufacturing
  Manufactured strictly according to customer-provided drawings, specifications, and tolerance requirements.

Application Scenarios / Industry Applications

• Injection Molding Tooling Systems
  Used as precision shafts, guiding elements, or functional components within injection mould assemblies.

• Packaging Mold Equipment
  Suitable for bottle cap moulds, closure moulds, and packaging-related mould tooling requiring stable slender shaft components.

• Medical Molding Tooling
  Applied in medical mould systems where corrosion resistance and surface quality are essential.

• Industrial Precision Assemblies
  Used in non-consumer industrial equipment requiring CNC-turned stainless steel shafts.
