Mold Structure & Design Description

Threaded bushes function as load-bearing and positioning elements within injection mould assemblies, ensuring reliable thread engagement between mould components. H13 material is selected for its balance of strength, toughness, and thermal stability. CNC machining ensures accurate thread geometry, concentricity, and seating surfaces to support long-term mould operation.

Manufacturing Capability & CNC Machining Capacity

Senlan Precision operates advanced machining equipment to ensure consistent quality:

• MAKINO CNC machining centers (Japan)

• HARDINGE CNC systems (USA)

• CNC turning and milling for internal and external threads

• Precision grinding for critical seating and reference surfaces

• Controlled heat treatment to achieve specified HRC range

Typical machining accuracy: ±0.01 mm, depending on part geometry.

Custom Development / OEM Cooperation Process

1. Review of customer drawings and technical requirements

2. Confirmation of H13 material and hardness specification

3. CNC machining, threading, and heat treatment
