Custom Stainless Steel Mold Core Plates | Precision Tooling for Daily Packaging

Product Overview

Non-standard stainless steel mold core plates are critical structural components used in plastic injection molds for daily packaging parts. Manufactured strictly according to customer drawings, these core plates provide stable mold support, precise cavity positioning, and long-term dimensional reliability in high-cycle production environments.

Key Features & Technical Advantages

• Manufactured from stainless steel for corrosion resistance

• Designed as non-standard, built-to-print components

• High structural rigidity for stable mold assembly

• Precision CNC machining ensures flatness and parallelism

• Suitable for long production cycles and frequent mold operation

• Compatible with multi-cavity and high-speed injection molds

Applications & Industry Use

• Daily packaging plastic part molds

• Bottle, container, and closure injection molds

• Medical consumable and disposable product molds

• Multi-cavity injection molding systems

• Mold assemblies requiring high structural accuracy

Mold Structure & Design Description

The mold core plate serves as a primary load-bearing and positioning element within the injection mold structure. Its dimensional accuracy directly affects cavity alignment, part consistency, and mold service life. Stainless steel material improves corrosion resistance and structural stability during long-term operation.
