D-2 Material Collapsible Core Inserts

Optimized CNC Machining for Complex Impellers

At Leadpoint, we combine advanced Japanese and Taiwanese CNC turning, centerless grinding, optical projection grinding (PG), and coordinate grinding (JG) technologies to manufacture these collapsible core inserts with exceptional precision. Each insert undergoes rigorous inspection, ensuring ±0.001 mm dimensional tolerance and surface roughness within Ra ≤0.05 µm.

Our engineering team also provides design optimization, material recommendations, and process consultation to help clients maximize mold performance, reduce cycle time, and extend mold life.

High-Precision Engineering

Our collapsible core inserts are manufactured using state-of-the-art CNC turning and grinding equipment from Japan and Taiwan, ensuring tight tolerances and perfect roundness. Optical projection and coordinate grinding are applied to critical surfaces for precision alignment and repeatable performance.

This allows smooth collapse during mold ejection, ensuring delicate internal geometries are produced without damage, and minimizing cycle time.

Durable D-2 Tool Steel Construction

Made from D-2 high-carbon, high-chromium tool steel, these inserts offer:

• Excellent wear resistance
• High compressive strength
• Stable hardness under repetitive molding
• Long service life for high-volume production

Ideal for cosmetic packaging, medical devices, and automotive molds where durability and precision are critical.

Optimized for Complex Molds

Collapsible core inserts enable molding of parts with:

• Internal threads
• Undercuts and grooves
• Hollow cavities
• Micro-diameter features

By integrating collapsible core technology, molds are simpler, cycle times are faster, and production is more reliable.

Custom Engineering Support

At Leadpoint, every insert can be tailored:

• Custom dimensions and tolerances
• Special surface treatments
• Material recommendations
• DFM consultation and mold optimization
• Prototype and mass production support

We collaborate closely with customers from design through final production to ensure the best results.
