Precision Stavax High Hardness Mold Core Plate for Daily Packaging Plastic Injection

Designed for high-output cap production, this 12-cavity precision mold cavity plate serves as a core component on the fixed side (cavity side) of injection molds. It forms the outer surface of plastic caps and closures while ensuring consistent part quality across all cavities—critical for packaging lines where dimensional repeatability and cycle stability directly impact scrap rates and throughput.

• Defines the external contour and cosmetic surfaces of caps/closures
• Ensures cavity-to-cavity consistency for reliable cap fit and sealing performance
• Provides stable interfaces for gating/venting features, cooling layout, and mold alignment
• Supports high-cycle production with optimized steel selection and heat treatment

• 12 cavity pockets arranged for balanced production
• Precision-machined mating and reference surfaces for repeatable assembly
• Multiple mounting and alignment holes for secure installation
• Localized gate/vent points near each cavity for fill balance and defect reduction

Optional coatings and treatments available based on specific wear and release requirements.

• Cosmetic caps for cream jars, serum bottles, and personal care packaging
• Flip-top caps and small closure components
• Dispensing closures and overcaps

• Bottle caps for beverages, condiments, and functional drinks
• Tamper-evident closure components

• Medicine bottle caps and closures
• Packaging caps requiring consistent sealing and clean appearance

• High-precision CNC milling and contour machining
• EDM / wire EDM for tight internal features
• Precision grinding of reference planes and parting interfaces
• Controlled heat treatment (vacuum hardening + tempering)
• Polishing to required grade specifications

• Cavity-to-cavity consistency control for multi-cavity molds
• Tight control on critical sealing and cosmetic surfaces
• Verification of flatness, parallelism, and datum relations

Precision cavity plates improve cavity balance and dimensional repeatability, reducing flash, short shots, and mismatch issues in high-cavity molds.

Stable cavity geometry supports reliable thread engagement, snap-fit consistency, and sealing performance—critical for functional cap requirements.

Appropriate steel selection and controlled heat treatment resist wear and corrosion, extending service life and supporting faster maintenance.

Proper surface finishing produces clean, high-quality caps at scale, meeting consumer packaging standards.
