§1What this business is
Aluminium alloy ingots and scrap are melted in an oil-fired furnace. For each shot, molten metal is ladled into the pouring sleeve of the die casting machine and a piston forces it into the die cavity under pressure; the part cools, the die opens and the casting is ejected. Castings are trimmed, ground, sand-blasted or buffed, inspected and packed. NSIC has two profiles: a general die casting unit and one making automobile parts on a horizontal cold-chamber machine. Buyers are vehicle, fan, motor and appliance makers.
Capacity: General unit 105 MT of castings a year; auto-parts unit 150 MT a year.
§2Is it right for you?
Who it is for
An engineer or foundry hand with contacts among vehicle-part, fan or appliance makers.
Who it is not for
Someone with no OEM buyers — die casting is almost always made to a buyer's drawing.
Advantages
- Vehicle, fan and appliance makers buy castings all year
- Each die turns out thousands of identical parts
- Aluminium scrap can be used along with ingots
Drawbacks
- Dies are costly and each new part needs a new die
- Buyers set tight size and finish limits and reject faulty lots
- Furnace work is hot and needs safety care
- Aluminium prices move with the metal market
Skills you need
- Melting and alloy control
- Die setting and die maintenance
- Fettling, grinding and finish checks
- Getting vendor approval from OEMs
Why difficulty 4/5: Costly dies, OEM quality approvals and hot metal work.
§3Market
Who buys
- Two-wheeler, car and tractor part makers
- Fan, motor and pump makers
- Appliance and lighting makers
How it sells
- Direct supply to OEMs and their tier-1 vendors against orders
- Job work on dies supplied by the buyer
Good to know
- The auto-parts profile stamps, inspects and despatches castings after finishing.

§7Money
How the investment is worked out: Two NSIC profiles, each printing one figure for machinery and equipment plus 3 months' working capital (raw material, utilities and salary): general die casting unit ₹55.60 lakh (105 MT a year); automobile parts by die casting ₹81.0 lakh (150 MT a year). No split is given, and land and building are not included.
Working capital: Working capital for 3 months is inside each total (₹55.60 lakh and ₹81.0 lakh); the profiles print no separate figure. The auto-parts unit uses 10 MT of aluminium ingot and 0.3 MT of scrap a month.
Year not printed on the NSIC profile (an older NSIC Training-cum-Incubation Centre sheet) — check current machinery and material prices.
§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: EEPC India
- Confirm the 8-digit ITC(HS) line with DGFT or your customs broker before shipping.
- You need an Import Export Code (IEC) from DGFT before the first shipment.
§9Risks — where people fail
- Porosity and size rejections
- Metal price swings
- Dependence on one or two large buyers
- Furnace emissions and burn accidents
§1030 / 60 / 90-day plan
