Mold And Components Solutions

Cosmetic Caps Mold

• Client’s Problem: A packaging manufacturer struggled with inconsistent thread sealing on cosmetic bottle caps due to ±0.03mm dimensional deviations in core pins. Failed caps caused leakage during testing, delaying product launches.

• Our Approach: Root Cause: Outdated grinding tools and thermal distortion in competitor’s process.
Precision Fix: Machined core pins using Hardinge CNC lathes with hydrostatic bearings (±0.005mm repeatability).
Applied Böhler steel with OEM heat treatment to minimize residual stress.
Verified geometry with Zeiss CMM and simulated mold flow for optimal thread engagement.

• Result: 99.8% cap sealing success rate in batch trials. Reduced client’s production downtime by 40%. Secured a 3-year exclusive supply contract for their premium cosmetics line.

Multi-Cavity Mold Components

A medical device manufacturer encountered dimensional instability in their 32-cavity syringe mold cores, resulting in ±0.015mm variation and flash formation. Their existing vendor's roughing strategy caused tool deflection in deep ribs.

• Our Approach: Process Breakdown:
High-Speed Hard Milling (HSM):
Employed Makino F5 with 42,000 RPM spindle for semi-finishing (radial engagement <15%)
Used Sandvik Coromant CBN tools for hardened steel (58 HRC) machining
EDM Finishing Protocol: Applied Sodick AQ550L with 0.02mm copper electrodes for rib corners (Ra 0.1μm)

• Result: Achieved ±0.005mm core-to-cavity match. 
Eliminated 100% flash-related rejects. 
Reduced electrode consumption by 40% through adaptive EDM. 
Client approved our process as their new gold standard
