Expocet Ltd provides expert sourcing and supply of high-grade Aluminium Die-Castings, offering both Gravity and High-Pressure manufacturing routes. These processes are the industry standard for producing lightweight, high-strength components with excellent dimensional repeatability and "near-net-shape" accuracy.

Our manufacturing partners are ISO 9001 and IATF 16949 certified, ensuring that all automotive and industrial components meet the most rigorous global quality standards.

Technical Capabilities & Processes

We offer a versatile range of die-casting solutions tailored to your specific volume and complexity requirements:

• Gravity Die-Casting (GDC): * Weight Range: 0.2kg – 80kg

  • Best For: Medium volumes and components requiring superior mechanical properties or heat treatment (e.g., T6).

  • Advantages: Lower tooling costs compared to pressure die-casting and the ability to use sand cores for complex internal cavities.

• High-Pressure Die-Casting (HPDC):

  • Weight Range: 0.05kg – 15kg

  • Best For: High-volume production runs (thousands to millions).

  • Advantages: Rapid cycle times, exceptionally thin wall sections, and superior surface finishes that often eliminate the need for secondary finishing.

Aluminium Alloy Expertise

We supply a wide variety of international standard alloys to suit specific environmental and structural needs, including:

• LM6 / LM25: Exceptional corrosion resistance and weldability.

• LM24 / A380: The standard for high-pressure casting, offering excellent fluidity and mechanical strength.

• Specialist Alloys: High-thermal conductivity alloys for heat sinks and electronics.

A Complete "Line-Ready" Solution

Expocet manages the entire manufacturing lifecycle to deliver fully finished components ready for your assembly line:

• Precision Machining: In-house CNC milling and turning to achieve microns-level tolerances.

• Surface Treatments: Including shot blasting, powder coating, anodising, and chromating for enhanced durability and aesthetics.

• Assembly & Sub-Assembly: We can provide individual components or complete sub-assemblies, including the insertion of helicoils, bearings, and seals.

• Impregnation: Vacuum impregnation services to ensure pressure tightness for fluid-handling components.

Industry Sectors Supplied

Our aluminium die-castings are critical to sectors where weight reduction and precision are paramount:

• Automotive & EV: Powertrain components, battery housings, and structural brackets.
• Lighting & Electronics: LED housings, heat sinks, and telecommunications enclosures.
• Hand Tools & Appliances: Lightweight, ergonomic housings for professional equipment.
• Pumps & Valves: Pressure-tight bodies for domestic and industrial fluid systems.
