Custom Plastic Injection Molding Service | Precision Mold Maker & Parts Production

Product Overview

Plastic injection mold cores and mold parts manufactured by Senlan Precision are engineered for high-accuracy plastic molding applications. Produced strictly to customer drawings, these mold cores and inserts are designed for stable dimensional control, long service life, and compatibility with single-cavity and multi-cavity injection molds used in packaging and medical industries.

Core Features & Technical Advantages

• Built-to-Print manufacturing based on customer drawings or 3D data

• High dimensional accuracy suitable for precision injection molding

• Stable performance under continuous injection cycles

• Compatible with replaceable mold core and insert mold structures

• Flexible material selection according to application requirements

• Suitable for high-cavity and high-output mold configurations

Applications & Industry Use

These plastic injection mold cores and mold parts are commonly used in:

• Bottle and container packaging injection molds

• Caps, closures, and dispensing component molds

• Medical disposable and syringe injection molds

• Laboratory plastic components and healthcare tooling

• Daily-use and hygienic packaging mold systems

All applications are related to industrial injection mold tooling, not finished consumer products.

Mold Structure & Design Description

Mold cores are critical forming components within plastic injection molds, directly defining internal geometry and functional features of molded parts. Typical design considerations include:

• Accurate alignment with cavity inserts and mold bases

• Optimized draft angles and surface finish for consistent demolding

• Structural strength for multi-cavity layouts

• Replaceable core design to reduce maintenance downtime

Senlan Precision manufactures mold cores strictly according to customer-approved designs without modification unless explicitly requested.

Manufacturing Capability & CNC Machining

Senlan Precision operates advanced CNC machining equipment from MAKINO (Japan) and HARDINGE (USA) to ensure stable and repeatable precision.

Manufacturing capabilities include:

• High-precision CNC milling and turning

• EDM machining for complex internal geometries

• Surface grinding and controlled polishing

• Heat treatment coordination when required

• Full dimensional inspection based on drawings

All processes follow defined tolerances and technical specifications.

Custom Development & OEM Cooperation Process

We support OEM / Built-to-Print cooperation with a structured workflow:

1. Drawing and technical requirement review
