What is a tungsten carbide rod project report?
A tungsten carbide rod project report is a detailed project report (DPR) for a plant that mixes tungsten carbide and cobalt powders, extrudes them into rods and sinters them to full density. It sets out the process, machinery, powder costs, market, project cost, means of finance, five-year projections, DSCR and break-even.
Promoters use it to size the plant and raise a term loan; banks and investors use it to judge whether the plant can repay at volatile tungsten prices.
Also known as: tungsten carbide rod business plan, cemented carbide rod project report, solid carbide rod plant DPR, project report on tungsten carbide rod.
Tungsten carbide rod manufacturing plant cost in India
Our sample report models a plant making 73 kg of rods per day, or 24,090 kg a year over 330 working days. It starts at 60% of capacity, reaches 80% in Year 5 and sells at ₹11,700 per kg.

Tungsten carbide rod manufacturing process
Long rods for end mills and drills are made by powder extrusion. Rods shrink by about a fifth in the furnace, so the extrusion die is sized larger than the finished diameter.
- Powder milling
Tungsten carbide powder, cobalt and grain growth inhibitors are wet-milled in attritor mills for several hours to an even mix.
- Spray drying
The milled slurry is dried into free-flowing grade powder with a fixed cobalt content.
- Kneading and extrusion
Grade powder is kneaded with a plasticiser and pushed through a die as round rods, plain or with helical coolant holes.
- Drying and dewaxing
Green rods dry on V-shaped trays, then the binder is burnt off slowly so they do not bend or crack.
- Sinter-HIP
Rods are sintered in a vacuum furnace near 1,400°C and pressed with argon gas to close the last pores.
- Cutting and grinding
Blanks are cut to standard lengths such as 310 or 330 mm and centerless ground when sold as ground rods.
- Testing and packing
Each batch is checked for hardness, density, porosity and straightness, then packed in tubes with its grade sheet.
Which route should a carbide rod plant use?
Two choices shape the machinery list and the project cost: how the rod is formed, and whether you make your own grade powder. The sample report uses extrusion, in-house milling and a sinter-HIP furnace.
| Extrusion | Best for long, small-diameter rods and coolant-hole rods. Needs a plasticiser and a slow, controlled dewaxing cycle. |
|---|---|
| Isostatic or die pressing | Suits larger diameters and shorter blanks. Pressed blanks often need green machining before sintering, which adds labour. |
| Vacuum sintering only | Lower furnace cost, but some porosity can remain. Most end mill makers ask for rods that have been pressure sintered. |
| Sinter-HIP | Sintering and argon pressure in one cycle. Gives near-zero porosity and is the norm for rods sold to cutting tool makers. |
| Own grade powder | Attritor mills and a spray dryer let you set cobalt content and grain size, and reuse recycled carbide. |
| Bought grade powder | Ready-to-press powder saves the milling section but leaves less margin and less control over the grade. |
Raw materials for tungsten carbide rods
Raw materials are 61.8% of sales in our sample report, and tungsten carbide powder alone is 82% of that bill. Rods for end mills usually use fine or sub-micron powder with about 6–12% cobalt, which holds the carbide grains together.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Tungsten carbide powder | 82% | 999.81 |
| Cobalt powder | 14% | 170.70 |
| Grain growth inhibitors (VC and Cr3C2) | 2% | 24.39 |
| Paraffin wax and extrusion binder | 2% | 24.38 |
| Total | 100% | 1,219.28 |
Machinery for a tungsten carbide rod plant
The sinter-HIP vacuum furnace is the largest item, about a third of the machinery cost in our sample. Its batch size and cycle time set the plant's real output, so size it before anything else.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Sinter-HIP vacuum furnace | Sinters rods to full density under argon pressure | 194.45 |
| Kneader and screw extrusion press | Mixes powder with plasticiser and extrudes rods | 80.07 |
| Centerless grinding machines | Grinds rods to size and tolerance | 68.63 |
| Attritor mills | Wet-mills carbide, cobalt and inhibitors | 57.19 |
| Spray dryer | Turns slurry into grade powder | 57.19 |
| Quality lab | Hardness, density and microstructure checks | 51.47 |
| Dewaxing furnace and drying ovens | Dries green rods and removes binder | 40.04 |
| Cut-off and chamfering machines | Cuts blanks to length and chamfers ends | 22.88 |
| Total plant and machinery | 571.92 | |

Power, gases and manpower
Power and fuel cost ₹129.19 lakh in Year 3 of our sample, or 6.5% of sales. The furnace, mills and grinders draw most of it, and the sinter-HIP cycle also needs a steady supply of argon.
A stable power supply matters more than the tariff. A power cut in mid-cycle can scrap a full furnace load, so plants plan a DG set or a dedicated feeder.
| Category | Number | Annual cost (₹ lakh) |
|---|---|---|
| Management, supervision and administration | 7 | 25.62 |
| Skilled workers and operators | 17 | 39.78 |
| Semi-skilled and unskilled workers | 24 | 37.44 |
| Total | 48 | 102.84 |
Licences and approvals for a carbide rod plant
| Business registration | Udyam (MSME) registration and GST registration |
|---|---|
| Pollution board consent | Consent to establish and operate from the State Pollution Control Board. The category comes from the board's list under the CPCB harmonised classification, so confirm it before you buy land. |
| Gas cylinder storage | Storing compressed gas in cylinders beyond the exempt quantity needs a Form F licence from PESO under the Gas Cylinders Rules, 2016. This applies to argon and any hydrogen kept on site. |
| Factory licence | Under the Factories Act where the worker and power thresholds apply, with dust extraction for cobalt and carbide powder areas |
| Product standard | The old BIS specification for tungsten carbide for mining tools, IS 4005:1967, is withdrawn. Buyers specify rods by cobalt content, grain size, hardness and tolerance on the maker's grade sheet. |
Who buys tungsten carbide rods in India?
Most rods go to tool makers who grind them into solid carbide end mills, drills and reamers. Their customers are auto component, aerospace, die and mould and general engineering shops, so rod demand follows machining activity.
A large share of rods used in India is imported. Tungsten supply also tightened in 2026: Miningreporters reported in April 2026 that China had limited tungsten exports to a short list of approved companies for 2026 and 2027.
- Solid carbide cutting tool makers
- Tool regrinding and reconditioning shops
- Die, mould and press tool makers
- Wear part and pump plunger makers
- Tooling traders and distributors
Where a local plant wins: tool makers want short delivery, small lots, custom lengths and coolant-hole rods. A domestic maker that holds consistent grades can serve them faster than importers who ship in bulk.
Mistakes that weaken a tungsten carbide rod project report
- Taking trader prices as your selling price
B2B portals list carbide rods at ₹15,000–24,000 per kg, but those are resale prices. A plant sells to tool makers at ex-factory rates, which our sample takes at ₹11,700 per kg.
- No test for powder price swings
Tungsten carbide powder is about half of sales in the sample. The report should show DSCR when powder rises and rod prices lag behind.
- Ignoring yield and grinding losses
Furnace rejects, cut-offs and grinding stock reduce saleable output. A report that sells every kilogram of powder overstates sales.
- Expecting full orders from day one
Tool makers trial new rods on their own grinders before they switch supplier. Plan for slow early sales, as the sample's 60% first-year use does.
- Under-funding receivables
Trade receivables are the largest current asset in our sample, ₹208.49 lakh in Year 1. Without them the cash credit limit comes out too small.

Tungsten Carbide Rod project report: frequently asked questions
How much does a tungsten carbide rod plant cost in India?
Our sample report models a 73 kg per day plant at ₹1,214.67 lakh, of which plant and machinery is ₹571.92 lakh. As an indicative range, plants of 40–120 kg per day cost about ₹8–20 crore. The spread depends on whether you mill your own grade powder, the sinter-HIP furnace make and how much grinding capacity you add.
What raw materials are used to make tungsten carbide rods?
Tungsten carbide powder and cobalt powder are the main inputs, with small amounts of vanadium and chromium carbide to stop grain growth and a wax or plasticiser for extrusion. In our sample report tungsten carbide powder is 82% of raw material cost and cobalt is 14%.
Which machines are needed for tungsten carbide rod manufacturing?
An extrusion plant needs attritor mills, a spray dryer, a kneader and an extrusion press. After that come drying ovens, a dewaxing furnace, a sinter-HIP vacuum furnace, cut-off machines and centerless grinders. A quality lab with a hardness tester, density balance and microscope checks every batch. The furnace is the largest single cost.
Is tungsten carbide rod manufacturing profitable?
In our illustrative sample, the plant earns a 14% return on investment in Year 3 and breaks even at 43% of capacity. It pays back in about 4.6 years, with an average DSCR of 1.39. Profit depends heavily on the gap between powder cost and rod price, so the report should test both.
Why have tungsten carbide rod prices gone up?
Rod prices follow tungsten powder prices, and tungsten rose sharply in 2026. Miningreporters reported in April 2026 that China, the largest supplier, had limited tungsten exports to a short list of approved companies for 2026 and 2027. A project report should use powder quotes dated close to the loan application.
What is the difference between ground and unground carbide rods?
Unground rods come straight from the furnace with a slightly rough surface and extra stock on the diameter. Ground rods are centerless ground to a close tolerance, usually h6, so tool makers can load them straight into grinding machines. Ground rods sell at a higher price but need grinders, wheels and sludge handling.
Is the tungsten carbide rod project report PDF free, and can I use it for a loan?
The sample is free to view and download. It is an illustrative report that shows the format and depth of an NPCS report. Its figures are representative and not from a real project, so do not submit it to a bank. For a loan, NPCS prepares a report for your own capacity, location and lender.
