Will your part run on that machine?

How do I know what machine tonnage my part needs?

Clamping force is set by the projected area of the casting — the shadow it throws on the parting plane, including runners and overflows — multiplied by the intensification pressure used to fill the die, plus a safety margin. Note that projected area is not length × width: a housing with a large bore may fill only half its bounding rectangle. A supplier who quotes without asking for projected area has not sized the job.

Take this from your CAD model — the shadow the casting throws on the parting plane, not its surface area.

Typical aluminium HPDC runs 40–100 MPa. Thin walls and pressure-tight parts sit at the higher end.

  • Add 25% for runners and overflows
  • Apply a 1.2× safety margin

India's die casting base, honestly described

India has an established aluminium die casting industry serving automotive, EV, electrical, lighting and general engineering. Suppliers range from small and mid-sized HPDC shops to fully automated plants running machines above 1,000 T.

The useful distinction for a buyer is not who owns the biggest machine. It is whether a supplier's tonnage class, alloy handling, tool room, inspection equipment and machining depth line up with the part you are placing — and whether those machines have hours free.

Seven questions to ask before you release the tool

Die casting fails late. Porosity, alloy drift and capacity problems usually surface after machining has already added value to the part.

What should I check before selecting a die casting supplier in India?

Confirm the machine your part will run on and the tonnage it needs, the porosity standard being quoted against, how pressure tightness will be proven, whether the tool room is in-house and who owns the die, how the melt is controlled, whether machining is in-house, and how much capacity is genuinely free.

Will my part actually run on that machine?

If they say"We have machines up to 900 T."
Ask forThe projected area your part presents, the intensification pressure they plan to use, and which specific machine it is scheduled on. Tonnage in a brochure is not tonnage available for your part.

What porosity level are you quoting to?

If they say"Our castings are high quality."
Ask forA written porosity standard and acceptance criteria — and for pressure-tight parts, whether vacuum assist is used. Porosity is the single biggest cause of die-cast rejections after machining.

How will pressure tightness be proven?

If they say"We do leak testing."
Ask forThe test method, pressure, dwell time and leak-rate limit, plus whether it is 100% or sampled. Impregnation is a fix, not a plan — ask how often it is used.

Is the tool room in-house, and who owns the die?

If they say"We handle all tooling."
Ask forWhether die design and manufacture are in-house or bought, expected tool life in shots, maintenance intervals, and written ownership on the PO.

How is the melt controlled?

If they say"We use ADC12."
Ask forSpectrometer records per heat, degassing practice, and how much returned scrap goes back into the melt. Alloy chemistry drift shows up as porosity and fails after machining, not before.

Is machining in-house or subcontracted?

If they say"Machining is no problem."
Ask forWhich operations run in-house, the CMM and fixture capability, and who carries the cost when a casting fails after machining value has been added.

What capacity is genuinely free?

If they say"We have plenty of capacity."
Ask forMachine hours available per month on the specific tonnage class, current utilisation, and shift pattern. A die casting cell running three shifts for an existing programme has no room for yours.

Where MESH fits

Machine list by tonnage, tool room, inspection equipment and certification scope — recorded by a MESH audit before a die caster reaches your shortlist, so the first call is about your part rather than their brochure.

Why integration matters here

A casting that fails after machining has already absorbed machining cost. When casting and machining sit with one supplier, that loss is theirs to manage rather than yours to argue about.

What to confirm

Which operations run in-house versus subcontracted, and where scrap responsibility transfers. Get it in the PO, not the quotation email.

High-pressure or gravity die casting?

Neither is better in general. Volume, geometry and mechanical requirements decide which one your part belongs to.

FAQ

Frequently asked questions

Molten aluminium alloy is forced under pressure into a reusable steel die, held while it solidifies, then ejected. High-pressure die casting on cold-chamber machines is the dominant method for aluminium, and suits complex, thin-walled components at volume.

Most established Indian die casters run cold-chamber HPDC machines from about 120 to 650 T. Larger cells at 650–900 T and 1,000–1,650 T are widely available from established suppliers. A small number of facilities report machines up to 3,000 T.

Everyday work sits in the small-component through roughly 1–1.5 kg class. Selected large-capacity plants report components up to 8 kg, and a smaller group to about 12 kg. Shot capacity and die size together set the limit, not a plant slogan.

ADC12, A380, LM24 and LM6 are the alloys most Indian die casters run every day. Selected suppliers also list A356, A360, AlSi10Cu2Fe, AlSi12 / AlSi12Fe, A413 and other application-specific grades. Confirm grade availability and melt practice before freezing the drawing.

Clamping force is set by the projected area of the casting — the shadow it throws on the parting plane, including runners and overflows — multiplied by the intensification pressure used to fill the die, plus a safety margin. Projected area is not length × width: a housing with a large bore may fill only half its bounding rectangle. Use the machine sizer on this page, then confirm against the drawing with the supplier.

Porosity is the single biggest cause of die-cast rejections after machining. Alloy chemistry drift, an undersized machine, leak paths that only show up on test, and machining a casting that was never pressure-tight all surface after value has already been added. Ask for a written porosity standard, melt records and how leak testing is actually run.

Yes. CNC / VMC machining, drilling, tapping and finishing are commonly offered with the casting. Selected plants run integrated multi-operation machining cells, CMM and leak testing under one roof. Confirm which operations are in-house versus subcontracted, and who carries the cost when a casting fails after machining.

High-pressure die casting suits high-volume, thin-wall, complex aluminium parts with a faster cycle and a higher tooling investment. Gravity die casting is generally slower, more limited by geometry, and often a better fit for lower to medium volumes and heat-treatable alloys. Volume, geometry and mechanical requirements decide which one your part belongs to.

A 3D model and 2D drawing with tolerances, aluminium alloy and temper, approximate casting weight, projected area if known, wall thickness and draft, surface-finish and leak or pressure-tightness requirements, annual volume and order frequency, first-order quantity, destination and Incoterm, and whether the die is new or existing — plus porosity standard, inspection and PPAP requirements.

ISO 9001 across most established die casters. IATF 16949 and other industry-specific systems from selected plants. Ask for certificate scope and expiry, and what inspection equipment an engineer actually saw on the floor — not only the badge.
