Aluminium Die Casting in India: Technology, Trends & Manufacturers

India’s aluminium die casting sector has witnessed robust growth in recent years, driven by rising automotive output, demands in aerospace, defence & energy, increasing “Make in India” push, and stricter norms for lightweight, fuel‑efficient components. Aluminium die casting manufacturers are increasingly investing in advanced technology, localization, quality, and capacity to better compete globally.

What Drives the Growth

• Automotive & EVs: As automakers shift toward lighter materials to meet emissions and efficiency regulations, aluminium parts (engine housings, transmission components, chassis parts) are in rising demand.

• Defence & Rail: There is increasing emphasis on domestic sourcing of critical components. Reduced dependency on imports is a government priority.

• Energy & Infrastructure: Switchgear, GIS (Gas Insulated Switchgear), power transmission, etc. need large, precise castings that aluminium can offer (lightweight, corrosion resistance).

• Technology & Quality: CAD/CAE/CAM, casting simulation tools, improved alloys & heat treatment, CNC machining etc., are increasingly part of die casting plants to meet high standards.

Key Players in India (Beyond the Usual)

• Taural India: A joint venture with Thoni Alutec (Germany/Poland), headquartered in Pune, Maharashtra. Taural India offers end‑to‑end sand casting aluminium solutions (from design and development through machining, painting, testing, assembly and delivery).

  • Their foundry can cast parts from ~7 kg up to 1,000 kg per casting.

  • They use advanced tools: CAD/CAE/CAM (SolidWorks, Siemens), MAGMASOFT for simulation, in‑house pattern shop, etc.

  • Recently they signed an MoU with the Maharashtra government to build a new facility in Supa (Ahilya Nagar) with investment of ₹500 crore; this plant will be ~4× the current in size.

  • They serve Energy, Defence, Railways, Marine, Aerospace, Infrastructure, EVs etc.

  • Their facility in Pune now is ~300,000 sq. ft., undertaking all steps from casting to final deliveries.
    
    

• Rockman Industries: One of the established names for aluminium die casting in India; supplies to auto sector with machined and painted assemblies etc.

• Ahresty India Pvt. Ltd.: Subsidiary of Japanese corporation, specialising in High Pressure Die Casting (HPDC), machining & assembly for automotive & industrial uses.

• Hinduja Foundries: While they also work with grey iron etc., their aluminium gravity die casting operations produce parts in range ~0.5‑16.5 kg. 

• Sipra Engineers Pvt. Ltd.: Long‐standing die cast specialist in western India, known for good automotive quality, in‑house tooling, etc.

Opportunities & Challenges

Opportunities

• The domestic demand for aluminium cast parts is increasing. According to market studies, annual aluminium demand in India is projected to grow ~9 % annually through 2025 in key sectors.
  
  

• Localization: Companies and government policies are promoting replacement of imported castings—Taural India’s supply of castings to Indian Railways (e.g., gear cases for WAP5 locomotives) is a case in point.
  
  

• Larger, heavier castings: Sand casting allows much larger sizes than many HPDC units; companies like Taural India are pushing limits (hundreds of kilograms to ~1000 kg castings). 

Challenges

• Capital investment needed for large machines, pattern shops, CAD/CAE simulation, heat treatment etc.

• Ensuring consistent alloy quality, defect control, meeting tight tolerances.

• Energy costs, raw material (aluminium alloy) supply and cost, logistics.

• Skilled workforce trained in modern casting, simulation, finishing, machining.

Taural India: Why it Stands Out

Taural India is not just another foundry; some of its distinguishing features:

• Offers sand casting for large, non‑standardized castings with high weight (up to 1000 kg), often used in heavy infrastructure, energy, defence etc.

• Full chain: From design & simulation to painting & assembly—all in one integrated facility. This reduces lead times and improves quality control.

• Recent large expansion plan: The Supa facility (₹500 crore investment) will greatly increase capacity and help decentralize manufacturing to Tier‑II/Tier‑III areas.

• Collaboration with global companies: Through JV with Thoni Alutec, they bring in European casting standards and practices. 

Conclusion

Aluminium die casting in India is going through an inflection point. With rising demand in automotive, EVs, defence, rail, energy and other sectors, manufacturers who invest in modern processes, quality, scale, and localization are well‑positioned. Taural India is a strong example of this trend—leveraging global partnerships, technology, and large scale investments, all while pursuing “Make in India” goals.
