H13 (SKD61) Guide Pillars & Bushings | Precision CNC Turned Mold Components

Product Overview

SKD61 guide bushings and guide pillars are precision alignment components used in plastic injection molds to ensure accurate mold opening and closing. Manufactured through CNC turning machining under a built-to-print model, these components provide stable guidance, wear resistance, and long service life in high-cycle molding applications.

Key Features & Technical Advantages

• Manufactured from SKD61 hot work tool steel

• Excellent wear resistance and structural stability

• CNC turning machining for consistent dimensional accuracy

• Smooth guiding surface to reduce friction and mold wear

• Stable performance under repeated mold opening cycles

• Fully customized / non-standard production according to drawings

Applications & Industry Use

• Plastic injection molds for bottle and container production

• Bottle cap and closure mold systems

• Medical consumable injection molds

• Multi-cavity and high-speed injection molding tools

• Mold assemblies requiring precise guiding and alignment

Mold Structure & Design Description

Guide bushings and guide pillars are critical alignment elements within injection mold assemblies. Proper fit and concentricity ensure accurate platen alignment, minimize side loads, and protect core and cavity components. SKD61 material supports stable guidance under thermal and mechanical stress during long production runs.

FAQ (Technical & Purchasing)

Q1: Are these guide bushings standard parts?
A: No. All guide bushings and guide pillars are manufactured as non-standard parts based on customer drawings.

Q2: What machining tolerance can be achieved?
A: Typical tolerance is ±0.002–0.005 mm, depending on geometry and application.

Q3: Why choose SKD61 for mold guide components?
A: SKD61 offers good wear resistance, strength, and thermal stability for repeated mold cycles.

Q4: Can these components be used in multi-cavity molds?
A: Yes. They are suitable for high-cycle, multi-cavity injection molding systems.
