Custom Plastic Injection Molding Service | Precision Mold & Parts Manufacturer

Product Overview

Custom plastic molding mold cores are precision-engineered components used as primary forming elements in plastic injection molds. Senlan Precision manufactures mold cores strictly according to customer drawings, focusing on dimensional accuracy, structural stability, and repeatable performance. These mold core parts are suitable for multi-cavity molds and high-cycle production environments across packaging and medical tooling applications.

Core Features & Technical Advantages

• Built-to-Print manufacturing based strictly on customer drawings

• High dimensional accuracy for stable mold performance

• Suitable for single-cavity and multi-cavity injection molds

• Optimized geometry for consistent filling and demolding

• Compatible with various mold steel grades and heat treatment processes

• Designed for long service life under repetitive molding conditions

Applications & Industry Use

Custom plastic molding mold cores are widely applied in:

• Plastic injection molds for packaging components

• Bottle, closure, and dispensing system molds

• Medical consumable injection molds

• High-cavity production molds requiring interchangeable cores

• OEM mold projects for export-oriented manufacturers

All applications focus on industrial mold tooling, without consumer product branding.

Mold Structure & Design Description

Within an injection mold system, mold cores function as:

• Primary shaping elements defining internal or external product geometry

• Structural components requiring precise alignment with cavity inserts

• Replaceable wear parts designed for maintenance efficiency

Design considerations include:

• Accurate fit with cavity and mold base

• Proper allowance for thermal expansion and cooling

• Surface finish requirements affecting demolding behavior

• Structural strength under injection pressure

Manufacturing Capability & CNC Machining

Senlan Precision manufactures mold core components using advanced CNC machining systems, including MAKINO (Japan) and HARDINGE (USA) precision equipment.

Manufacturing capabilities include:

• High-precision CNC milling and turning

• Profile and cylindrical grinding

• EDM machining for complex core geometries

• Controlled heat treatment and stress relief

• In-process and final dimensional inspection

These processes ensure consistency from prototype to batch production.
