The 16-Cavity Precision Mold Core Insert is a high-precision mold component designed for multi-cavity plastic injection molds used in packaging, medical consumables, and high-volume plastic production. This insert forms the core side of the mold, shaping internal features of molded plastic parts while ensuring consistent part quality across all cavities.

Manufactured from high-performance mold steels such as STAVAX, 1.2083, or stainless tool steels, this multi-cavity core insert is engineered to provide excellent corrosion resistance, dimensional stability, and long service life in demanding injection molding environments.

The insert integrates multiple precision-machined cavities and runner channels, enabling balanced plastic flow and efficient mass production in multi-cavity mold systems.

• Multi-cavity 16-cavity mold design
• Precision machined core insert block
• Suitable for plastic injection mold tooling
• Integrated runner channel system
• Excellent wear resistance and corrosion resistance
• Replaceable modular mold insert design
• Machining tolerance up to ± 0.005 mm

Used in molds producing packaging components such as small containers, caps, lids, and cosmetic packaging parts.

Applicable for molds producing medical disposable plastic components, including connectors, caps, and laboratory consumables.

Used in molds producing precision plastic parts for household and daily-use products.

Ideal for high-efficiency molds designed to produce multiple parts per injection cycle.

Suitable for molds producing cosmetic caps, lids, and packaging accessories requiring high surface quality.

• High-precision CNC milling and machining
• Precision grinding for tight tolerances
• Advanced runner channel machining
• Mirror polishing for high surface finish
• Professional heat treatment and material processing
• Precision dimensional inspection using advanced measuring equipment

We can achieve machining tolerances up to ± 0.005 mm, ensuring consistent cavity alignment and reliable mold performance.

Multi-cavity mold inserts allow molds to produce multiple plastic parts in each injection cycle, significantly increasing production capacity.

Replaceable inserts allow worn cavities or damaged sections to be replaced without rebuilding the entire mold.

Precision machining ensures uniform cavity geometry, improving dimensional consistency across all molded parts.

Modular mold inserts reduce mold repair time and lower long-term tooling costs.

Insert-based mold structures allow easy upgrades when product designs change.
