Precision 1.2083 Mold Core Insert Block for Injection Mold Tooling
Product Overview
The Precision 1.2083 Mold Core Insert Block is a high-precision mold component designed for plastic injection mold tooling used in packaging and medical plastic production. This component functions as a core insert, forming the internal geometry of molded plastic parts while ensuring dimensional accuracy and consistent production performance.
Manufactured from 1.2083 stainless mold steel (DIN standard), the insert offers excellent corrosion resistance, high hardness after heat treatment, and superior polishability. These properties make it particularly suitable for molds used in medical consumables, cosmetic packaging, and high-hygiene plastic components.
The multi-cavity structure allows the mold to produce multiple parts in each injection cycle, improving manufacturing efficiency while maintaining uniform product quality.
Product Description
A mold core insert block is a modular mold component installed inside the core side of a plastic injection mold. It is responsible for forming the internal shape, holes, and functional structures of molded plastic parts.
Instead of machining the entire mold core plate from one piece of steel, many molds adopt replaceable insert blocks. This modular structure offers several operational advantages:
- Simplified mold maintenance
- Faster replacement of worn cavities
- Reduced mold repair costs
- Improved machining precision for complex geometries
Material Properties
1.2083 stainless mold steel is widely used in precision injection molds due to its excellent material properties:
- High corrosion resistance
- Good wear resistance
- Excellent mirror polish capability
- Stable hardness and dimensional stability
