Dense & accurate
Intensified pressure during solidification yields sound, dimensionally repeatable castings at volume.
Capability · Aluminium HPDC
Aluminium Pressure Die Casting
Automated high-pressure die casting of aluminium for dense, dimensionally accurate, repeatable components at volume — cast, machined, finished and inspected under one ISO 9001:2015 roof. Send your drawing and we'll review feasibility and quote, usually within one business day.
The Process
What high-pressure die casting is — and when to use it
In high-pressure die casting (HPDC), molten aluminium is forced into a hardened steel die at high pressure and high speed, then held under pressure as it solidifies. That rapid fill and intensified pressure produce dense parts with crisp detail, thin walls and an excellent surface straight from the die — with very little machining stock to remove afterwards.
It is the right process when you need repeatable, dimensionally consistent parts in medium-to-high volumes: housings, covers, brackets, heat sinks and structural components where wall sections are thin and net-shape accuracy matters. Tooling is a real up-front investment, so HPDC pays off when annual quantities justify it. Share your drawing and we'll recommend the alloy, tooling and finishing route that actually suits your part rather than the one that suits our shop.
- Dense, net-shape parts with thin walls and fine detail
- Repeatable dimensional accuracy, shot after shot
- Smooth as-cast surface, ready for coating or light machining
- Economical once volumes justify the tooling
Our HPDC Capability
Automated casting, built for volume and consistency
Pressure die casting is the core of everything we make. We cast in excess of 2,000 metric tonnes of processed aluminium every year across three production units, on automated high-pressure machines that hold fill, pressure and cycle parameters consistent from the first part to the last. Process discipline is backed by ISO 9001:2015 certified quality systems and Six Sigma practices, audited every year.
Machine tonnage range and your part's maximum size and weight are confirmed against your specific drawing — share your part envelope and we'll tell you exactly what we can run. The same goes for tolerances and surface finish: both are confirmed per drawing and post-treatment rather than promised in the abstract.
Controlled & audited
ISO 9001:2015 and Six Sigma-driven process control, with annual audits and stage-wise inspection.
Capacity at scale
2,000+ MT of processed aluminium a year across three units — sampling through to series production.
Materials · BS 1490 LM-Series
The aluminium alloys we typically die-cast
We cast the BS 1490 LM-series of aluminium alloys. For high-pressure die casting, a few grades do most of the work:
- LM24 (≈ A380 / ADC10) — the HPDC workhorse: a great all-round balance of castability, strength and value for housings, gearbox cases, brackets and general components.
- LM2 (≈ A383 / ADC12) — excellent fluidity for thin-section housings, covers and manifolds.
- LM6 — eutectic Al-12Si for thin, intricate, corrosion-resistant castings.
- LM20 — the pressure-die counterpart to LM6, well suited to thin, leak-tight, corrosion-resistant parts.
Final grade selection also depends on wall thickness, post-treatment and your spec sheet. Compare chemistry, international equivalents and typical applications side by side in our aluminium die-casting alloy guide, or use the live alloy selector to score every LM-series grade against the properties that matter for your part.
One-Stop Advantage
From tooling to finished, inspected part — one accountable partner
A die-cast part rarely ships straight from the machine, and juggling separate vendors for tooling, machining and finishing splits accountability and stretches lead times. We keep the whole chain in-house:
- In-house tool room designing and building pressure dies, jigs and fixtures, with DFM input before any steel is cut.
- Fettling, drilling, tapping and CNC machining to bring every casting to final tolerance.
- Shot blasting, powder and primer coating for clean, durable, corrosion-resistant finishes.
- Material and dimensional inspection with certificates of conformance and lot traceability on request.
The result: one point of contact, one quality system and one party answerable for the part from drawing to dispatch.
Applications
Where our die castings go to work
We supply aluminium pressure die castings across demanding sectors — power generation and drive (starter motors, alternator covers, driving-end covers), lighting (including LED heat sinks), cookware and appliances, agricultural equipment, and industrial components such as fans, pneumatic cylinder parts and tile cutters. As an approved supplier to OEMs including Godrej & Boyce and Lawkim Motors, we cast to specification for both domestic Indian manufacturers and export buyers. See the full range under products & applications, or read how we support export of aluminium castings worldwide.
