High Pressure Die Casting Manufacturer in Pune

Plasma Aluminium Diecasting is a high pressure die casting (HPDC) manufacturer in Pune, India, producing precision aluminium components for automotive, aerospace, electrical and industrial applications. With in - house tooling, CNC machining and powder coating, the company serves clients across Chakan, Moshi and nationally.

High pressure die casting accounts for roughly 50% of all non - ferrous castings produced globally and automotive applications drive the majority of HPDC demand in India. In the Pune - Chakan corridor alone, the push toward EV platforms has added new complexity to HPDC requirements - thinner walls, tighter tolerances and higher thermal management demands - making the choice of HPDC manufacturer one of the most consequential supply chain decisions an automotive Tier - 1 makes.

High Pressure Die Casting Manufacturer in Pune – Precision HPDC Components for Every Industry

High Pressure Die Casting (HPDC) is the backbone of modern aluminium component manufacturing. It is the process that makes high-volume, tight-tolerance, geometrically complex parts economically viable—and it is the process most commonly specified by automotive OEMs, Tier-1 suppliers and electrical manufacturers operating across Pune, Chakan and Moshi.

At Plasma Aluminium Diecasting, HPDC is our highest-volume capability. We produce precision aluminium components using high-pressure injection technology, supported by in-house tooling development, CNC post-processing and powder coating—all under one roof at our Pune facility.

Whether you are sourcing HPDC components for the first time or looking to transfer existing production from another supplier, our engineering team can take you from drawing to delivery-ready component with the technical depth and process discipline that precision manufacturing demands.

What Is High Pressure Die Casting?

High Pressure Die Casting is a process in which molten aluminium alloy is injected into a precision-machined steel die at pressures typically ranging from 1,000 to 1,500 bar. The high injection speed fills the die cavity in milliseconds and the component solidifies under pressure in a matter of seconds. The result is a component with:

  • Excellent dimensional accuracy and tight tolerances
  • Smooth, consistent surface finish suitable for direct use or minimal post-processing
  • Complex geometries including thin walls, internal cavities and integrated features
  • High production rates with short cycle times—ideal for large-volume programmes

HPDC is well suited to aluminium alloys with good castability and moderate to high strength, including ADC12 and A380, both of which Plasma works with routinely.

Our HPDC Process at Plasma – Step by Step

  1. Design and DFM Review: Our engineers review your drawing for manufacturability, flagging gate locations, draft angles, wall thickness consistency and features that may require post-machining.
  2. In-House Tooling Development: We design and fabricate the HPDC tool in-house, controlling gate design, venting and thermal management from the start.
  3. Trial Shots and First Article Inspection: First samples are measured and inspected before production is released, with full dimensional report provided.
  4. Production Casting: Components are cast in controlled cycle conditions with in-process monitoring of shot parameters.
  5. Post-Casting Processing: Where specified, components proceed to in-house CNC machining and powder coating.
  6. Final Inspection and Dispatch: Full dimensional check and visual inspection before packing and delivery.

Why HPDC Is the Right Choice for High-Volume Aluminium Components

For manufacturers who need a consistent, high-volume supply of aluminium components at competitive per-unit costs, HPDC offers an unmatched combination of advantages:

  • Cycle times of 15 to 90 seconds per shot depending on component size and wall thickness
  • Dimensional repeatability within tight tolerances across the full production run
  • The ability to integrate multiple features—ribs, bosses, holes, inserts—into a single casting, eliminating secondary assembly operations
  • Tooling that is designed for high-cycle longevity, amortising tool investment across a large production volume

For programmes in the thousands to hundreds of thousands of units per year, HPDC consistently delivers the best combination of quality, throughput and cost.

Alloys Used in Our HPDC Process

Plasma's HPDC process operates with a range of industry-standard aluminium alloys, selected based on the component's mechanical, thermal and surface requirements:

  • ADC12 (JIS standard): The most widely used HPDC alloy globally. Excellent castability, good mechanical properties and reliable surface finish. Standard choice for automotive and general industrial components.
  • A380: Preferred for applications requiring good corrosion resistance and dimensional stability. Widely used in electrical housings and enclosures.
  • LM24: Similar to ADC12 in composition, commonly used for complex castings in the Indian market.

We can also work with other aluminium alloys based on client specification. Alloy selection is reviewed during the design and quotation stage.

HPDC Tooling: Why In-House Matters

The quality of any HPDC component is determined largely by the quality of the tool that produces it. By developing and fabricating tooling in-house, Plasma eliminates the information loss and timeline risk that comes with outsourcing this critical stage.

Our in-house tooling capability means:

  • Faster first-shot timelines—typically 4 to 8 weeks for standard HPDC tools
  • Design modifications can be executed directly, without waiting on a third-party tool shop
  • Tooling is maintained, inspected and serviced within our own facility, with full lifecycle tracking
  • Gate and venting designs are optimised by our engineers who also cast the components—closing the feedback loop between tooling and production

Quality Assurance in HPDC Production at Plasma

HPDC components at Plasma are subject to a comprehensive quality programme:

  • Raw material certification review before each melt
  • Shot parameter monitoring (injection speed, pressure, fill time) throughout production
  • Dimensional inspection of first-off and periodic in-process samples
  • Visual inspection for surface defects (cold shuts, flash, porosity, mis-runs)
  • Where specified: X-ray inspection, CMM measurement reports, or statistical process control data

Serving the Pune, Chakan & Moshi HPDC Market

Plasma's HPDC manufacturing facility is strategically positioned to serve the dense industrial cluster spanning Pune, Chakan MIDC, Moshi MIDC and Chimbli. For automotive and electrical manufacturers in this corridor, a locally based HPDC supplier reduces logistics costs, compresses first-article inspection cycles and enables the kind of close engineering collaboration that remote suppliers simply cannot offer.

Frequently Asked Questions (FAQs)

High pressure die casting (HPDC) is a process in which molten aluminium is injected into a steel mould at 1,000 - 1,500 bar pressure, producing complex, dimensionally accurate components with smooth surfaces in very short cycle times. Key advantages include high production rates, excellent dimensional repeatability, the ability to produce thin - walled and complex geometries and competitive per - unit cost at high volumes.

HPDC can reliably achieve wall thicknesses as low as 1.5 to 2 mm for aluminium alloys, depending on the alloy, gate design and component geometry. Our tooling and process engineers review wall thickness requirements during the design stage to ensure the tool design supports consistent fill and solidification.

We supply HPDC components to the automotive, EV, aerospace, electrical, industrial machinery and FMCG sectors. Automotive and electrical applications represent our largest HPDC volumes, with growing demand from EV programmes that require precision battery brackets, motor housings and thermal management components.

Our quality processes are structured to align with the documentation, traceability and inspection requirements of automotive and industrial supply chains. We provide first - article inspection reports, process monitoring data and dimensional reports as standard on HPDC production. Please specify your quality standard requirements in your enquiry and we will confirm our alignment.
