Precision Die Casting Punch Pins | Custom Cooling Hole (SR-Type) Mold Parts

Product Overview

Portable Die Casting Mold Parts – Precision Punch Pins with SR-Cooling Hole are high-accuracy mould components designed for efficient heat dissipation and stable forming performance in injection mould systems. Manufactured by Senlan Precision, these punch pins are produced strictly on a Built-to-Print (OEM) basis, integrating internal SR-type cooling holes to support thermal control and dimensional stability during continuous moulding operations.

Key Features & Advantages

• Precision punch pins with integrated SR cooling hole design

• Improved heat dissipation to reduce thermal deformation

• Stable dimensional accuracy under repeated mould cycles

• Suitable for portable and compact mould structures

• Custom materials, hardness, and surface finish per drawing

• Designed for long service life in high-cycle mould applications

Applications / Industry Use

• Injection mould punch and forming systems

• Packaging moulds for bottle and cap components

• Multi-cavity moulds requiring thermal balance

• Medical consumable mould tooling

• Precision mould assemblies requiring controlled cooling

Mould Structure & Design Description

Punch pins with internal SR cooling holes are engineered to manage localized heat concentration during moulding. By integrating internal cooling channels, thermal gradients around the pin tip are reduced, helping maintain consistent forming dimensions and surface quality.

Key design considerations include:

• Accurate positioning of cooling holes relative to the working tip

• Controlled wall thickness to maintain mechanical strength

• Compatibility with mould cooling circuits

• Optimized geometry for stable ejection and forming

All punch pins are manufactured strictly according to customer-supplied drawings and technical specifications.

Manufacturing Capability & CNC Machining

Production of precision punch pins follows a controlled machining workflow:

• CNC turning and milling for structural accuracy

• Deep hole drilling or EDM for SR cooling hole formation

• Precision grinding to meet tight tolerance requirements

• Optional heat treatment and surface finishing

• Final dimensional verification before shipment

Manufacturing is supported by advanced equipment from MAKINO and HARDINGE, ensuring repeatable quality suitable for export-grade mould components.
