Precision Die Casting Mold Inserts | Brass, Copper & SUS304 Core Pins

Product Overview

Long Life Die Casting Mold Parts – Brass Cu / SUS304 Insert Core (1.0 mm Thickness) are precision-engineered mould components designed for applications requiring thin-wall accuracy, corrosion resistance, and stable long-term performance. Manufactured by Senlan Precision on a custom / OEM / Built-to-Print basis, these insert cores combine controlled material selection with high-precision machining to support consistent mould operation in demanding production environments.

Key Features & Advantages

• Brass Cu and SUS304 material options for corrosion resistance and thermal stability

• Thin-wall insert core design with 1.0 mm thickness control

• Stable dimensional accuracy for long service life

• Suitable for high-cycle moulding operations

• Precision machining to ensure reliable fit and alignment

• Manufactured strictly according to customer drawings (Built-to-Print)

Applications / Industry Use

• Packaging mould components for bottles and containers

• Medical mould inserts requiring corrosion resistance

• Moulds with replaceable insert core structures

• High-precision mould tooling requiring long operational lifespan

Mould Structure & Design Description

Insert cores play a critical role in defining internal geometry and surface quality of moulded parts. The 1.0 mm thickness design requires precise material control and machining accuracy to prevent deformation during moulding cycles. Brass Cu provides excellent thermal conductivity, while SUS304 offers superior corrosion resistance, making these insert cores suitable for applications where stability and durability are essential.

Manufacturing Capability & CNC Machining

Senlan Precision applies controlled machining processes to achieve consistent quality:

• CNC turning for insert core geometry

• CNC milling for functional and interface features

• Precision grinding for thickness and tolerance control

• Fine surface finishing to meet drawing specifications

• Strict dimensional inspection at each critical stage

Production is supported by advanced equipment, including MAKINO (Japan) and HARDINGE (USA) precision machining centers.

FAQ – Technical & Purchasing

Q1: Can you maintain 1.0 mm thickness with tight tolerance?
Yes. Thickness control is achieved through precision grinding and verified during inspection.

Q2: How do Brass Cu and SUS304 differ in application?
Brass Cu offers better thermal conductivity, while SUS304 provides higher corrosion resistance. Selection depends on moulding conditions.

Q3: Are standard sizes available?
No. All insert cores are produced strictly according to customer drawings.

Q4: Do you support small-batch or prototype orders?
Yes. Both prototype and production quantities are supported under OEM cooperation.
