Exothermic Mould Manufacturer – High-Precision Welding Solutions

Leading Exothermic Mould Manufacturer for Reliable Electrical Connections

As a trusted Exothermic Mould Manufacturer, SG Power delivers high-quality, precision-engineered moulds designed for consistent and permanent exothermic welding connections. Our exothermic moulds are manufactured using premium-grade graphite and advanced machining processes to ensure superior thermal resistance, dimensional accuracy, and long service life.

Exothermic moulds play a critical role in creating molecular-level bonds between conductors, ensuring low electrical resistance and long-term reliability. These moulds are widely used in earthing systems, lightning protection installations, railways, substations, power plants, telecom infrastructure, and industrial grounding applications.

What Is an Exothermic Mould?

An exothermic mould is a specially designed graphite mould used in the exothermic welding process (also known as thermite welding). It holds conductors in precise alignment while exothermic welding powder melts and fuses them into a permanent, corrosion-resistant joint.

Unlike mechanical clamps or bolted joints, exothermic weld connections:

Do not loosen over time

Offer equal or higher conductivity than the parent conductor

Are resistant to corrosion and environmental stress

Require no external power source

This makes exothermic moulds essential components for critical grounding and bonding systems.

Precision Manufacturing Process

As an experienced Exothermic Mould Manufacturer, we follow a stringent manufacturing and quality control process to deliver moulds that perform flawlessly in real-world conditions.

Premium Graphite Material

Our moulds are manufactured using high-density, fine-grain graphite, selected for:

Excellent thermal shock resistance

High melting point

Minimal erosion during repeated welds

Smooth internal surfaces for clean weld formation

CNC Machining for Accuracy

Each exothermic mould is CNC-machined to ensure:

Perfect conductor alignment

Accurate weld cavity dimensions

Uniform molten metal flow

Consistent weld strength

This precision directly impacts weld quality and joint reliability.

Types of Exothermic Moulds We Manufacture

Conductor to Conductor Moulds

Designed for straight, T-type, cross, or parallel conductor connections commonly used in earthing and grounding systems.

Conductor to Ground Rod Moulds

Used for bonding copper or GI conductors to copper-bonded or solid ground rods.

Conductor to Busbar Moulds

Ideal for substations, panels, and electrical rooms where busbar grounding is critical.

Custom Exothermic Moulds

As a flexible Exothermic Mould Manufacturer, we also design custom moulds based on drawings, conductor sizes, and application requirements.

Technical Advantages of Our Exothermic Moulds

High reusability with consistent weld quality

Engineered for uniform heat distribution

Reduced weld defects and slag inclusion

Minimal powder wastage

Compatible with standard exothermic welding powders

Each mould is tested to ensure dimensional accuracy and performance before dispatch.

Applications Across Industries

Our exothermic moulds are widely used in:

Electrical earthing and grounding systems

Lightning protection systems

Power generation and transmission

Railways and metro projects

Telecom towers and data centers

Oil & gas plants

Renewable energy installations (solar & wind)

Wherever safety, conductivity, and permanence are critical, exothermic moulds are the preferred solution.
