Mold Structure & Design Description

Locating blocks and slide retainers are key structural elements that control slide movement, alignment, and repeatability within injection moulds. SKH51 material is selected for its superior wear resistance and strength, making it suitable for high-load sliding interfaces. Precision machining ensures accurate positioning, reduced friction variation, and reliable mould operation over long production cycles.

Manufacturing Capability & CNC Machining Capacity

Senlan Precision operates advanced machining equipment to meet tight tolerance requirements:

• MAKINO high-precision CNC milling centers (Japan)

• HARDINGE CNC lathes (USA)

• CNC milling, drilling, surface grinding, and profile grinding

• Controlled heat treatment coordination for SKH51 steel

Typical machining tolerances can reach ±0.002–0.005 mm, depending on component geometry.
