Custom EDM Stavax ESR Mold Components | Precision Injection Mold Core Pins

Product Overview

The customized EDM Stavax injection mold core pin is designed for high-precision plastic mould applications requiring excellent corrosion resistance, surface integrity, and dimensional stability. Manufactured from Stavax stainless mould steel and processed with EDM where complex geometries are involved, this core pin is suitable for multi-cavity injection moulds used in packaging and medical plastic components. Built-to-print manufacturing is supported.

Key Features & Advantages

• Stavax Stainless Mold Steel
  High corrosion resistance and uniform hardness, suitable for humid environments and medical-grade moulds.

• EDM Machining Capability
  Electrical discharge machining enables complex profiles, deep features, and sharp internal geometries that are difficult to achieve with conventional cutting.

• High Dimensional Accuracy
  Tight tolerance control ensures stable fit and repeatability in multi-cavity injection mould systems.

• Excellent Surface Integrity
  Controlled EDM finishing combined with post-processing reduces micro-cracks and improves mould life.

• Built-to-Print Customization
  Fully customized core pins manufactured according to customer drawings and technical specifications.

Application Scenarios / Industry Use

• Plastic bottle caps and closures

• Medical consumables and disposable moulded parts

• Cosmetic and daily packaging moulds

• Multi-cavity injection mould systems

• Precision plastic mould tooling components

Mold Structure & Design Description

The Stavax core pin functions as a critical forming element within injection mould assemblies, directly affecting part geometry and surface quality. EDM processing is applied for areas requiring sharp corners, blind cavities, or complex internal contours. The core pin is engineered to maintain concentricity, straightness, and dimensional stability under repeated injection cycles, ensuring consistent mould performance.

Frequently Asked Questions (FAQ)

Q1: Can you manufacture core pins only based on drawings?
Yes. We specialize in built-to-print manufacturing strictly according to customer drawings.

Q2: Is EDM necessary for all Stavax core pins?
No. EDM is applied only when the geometry or internal structure requires it. Conventional CNC machining is used where possible.

Q3: Are these core pins suitable for medical moulds?
Yes. Stavax stainless steel is widely used in medical and hygienic plastic mould applications.

Q4: Can you support multi-cavity mould projects?
Yes. We have extensive experience producing core pins for high-cavity injection moulds.
